Referring to
The electronic device 400 may be configured to include: a display 410; a housing (or body) 420 on which the display 410 is mounted to be fixed; and additional devices that are formed in the housing 420 in order to thereby execute functions of the electronic device 400. The additional devices may include the first speaker 401, the second speaker 403, a microphone 405, sensors (such as a front camera module 407, an illuminance sensor 409, or the like), communication interfaces (e.g., a charging or data input/output port 411, an audio input/output port 413, or the like), a button 415, or the like.
The display 410 may include the flat panel type of display or a bent display that can be curved, bent, or rolled without being damaged through a thin and flexible substrate like paper. The bent display may be coupled to the housing 420 so that a curved shape thereof may be maintained. In addition to the bent display, the electronic device 400 may be implemented by a display device that can be freely bent and unfolded, such as flexible displays. The display 410 may have the flexibility to be folded and unfolded by replacing glass substrates, which enclose a liquid crystal in an, an LED, an OLED, or an active matrix OLED (AMOLED), with plastic films.
The electronic device 400 may be connected to one audible device (for example, the audible device that operates as a master among the audible devices 500) of the audible devices 500 (for example, the first audible device 510 and the second audible device 520). The electronic device 400 may be connected to the audible device 500 based on wireless communication ((e.g., Bluetooth, Bluetooth low energy (BLE), or the like)).
When the electronic device 400 is connected to the audible device 500, the electronic device 400 may determine state information (such as wearing state information or the battery level (e.g., information on the remaining amount of the battery)) corresponding to the audible device 500. The electronic device 400 may control the operation of the audible device 500 (e.g., the first audible device 510 or the second audible device 520) based on the state information of the audible device 500.
The electronic device 400, for example, may control at least one of the first audible device 510 or the second audible device 520 to perform the first work (e.g., a stereo audio output function based on the first audible device 510 and the second audible device 520) and the second work (e.g., a health coaching function for the user), which are performed by the interworking between the electronic device 400 and the audible devices 500.
When controlling the operation related to the first work and/or the second work of the audible device 500, based on whether or not the audible device 500 is worn on the user, the electronic device 400 may distribute the works of the audible device 500 such that the audible device 500, which is worn on the user's body (such as the ears), may perform the first work and/or the second work.
When controlling the operation related to the first work and/or the second work of the audible device 500, based on the balancing of the battery level between the first audible device 510 and the second audible device 520, the electronic device 400 may distribute the works of the audible device 500 such that the corresponding audible device 500 may perform the first work and/or the second work. For example, if the electronic device 400 detects that the battery level of one (e.g., the first audible device 510) of the first audible device 510 or the second audible device 520 is lowered to be equal to, or less than, a reference voltage (for example, 3.6V), the electronic device 400 may adjust the sound quality, which is to be transmitted to the audible device (e.g., the first audible device 510) of which the battery level is lowered to be equal to, or less than, the reference voltage, to be lower (for example, 192 Kbps→96 Kbps) than the sound quality that is transmitted to the other audible device (e.g., the second audible device 520), and may transmit the same.
The electronic device 400 may distribute the works of the audible device 500 such that at least one of the first audible device 510 or the second audible device 520 may perform the first work and/or the second work based on whether or not the audible device 500 is worn on the ear and based on the battery level.
The electronic device 400 may control the audible device, which is worn on the ear and of which the battery level is high, to operate the first work and the second work, which are performed by the interworking between the electronic device 400 and the audible device 500.
For example, as shown in
As another example, when both the first audible device 510 and the second audible device 520 are worn on the ears and the electronic device 400 is connected with the second audible device 520 as a master, it may be assumed that the battery level (e.g., the remaining amount of the battery) 515 of the first audible device 510 becomes higher than the battery level (e.g., the remaining amount of the battery) 525 of the second audible device 520 or the second audible device 520 is taken off, as shown in
The electronic device 400 may determine the wearing or non-wearing state of the corresponding audible device 500 based on state information that is received from the first audible device 510 or the second audible device 520. The electronic device 400 may compare the voltage of the audible device 500 based on the state information that is received from the first audible device 510 or the second audible device 520, and may make a control to give priority for performing the operation to the audible device of a high voltage (e.g., the first audible device 510) to then perform the corresponding operation. The electronic device 400 may control the second audible device 520 to operate in the standby state (e.g., the sleep state) in order to thereby minimize the current consumption of the second audible device 520.
Although the battery level of the first audible device 510 is higher than the battery level of the second audible device 520, the user may wear only the second audible device 520 on the ear without recognizing the same. The electronic device 400 may obtain, from the audible device 500, sensed information that is measured by various sensors provided in the audible device 500, and may determine the audible device (e.g., at least one of the first audible device 510 or the second audible device 520) to be worn on the user's ear based on the same. For example, if the electronic device 400 detects that only the second audible device 520 is worn on the user's ear, even though the battery level of the first audible device 510 is higher than the battery level of the second audible device 520, the electronic device 400 may control the second audible device 520 to process the works that have been allocated to the first audible device 510.
Examples in which the electronic device 400 controls the operation according to the state information of the audible device 500 will be described in detail with reference to the drawings.
The audible device 500 may represent an audio output device that is connected with the electronic device 400 in wireless communication in order to thereby receive audio signals of sound sources (e.g., audio data) that are reproduced in the electronic device 400 and are transmitted through streaming, and in order to thereby output the received audio signals through a provided speaker (or a receiver). The audible device 500 may be configured by a pair of audible devices, such as the first audible device 510 and the second audible device 520 for the left ear and the right ear of the user, respectively. The audible device 500 including the first audible device 510 and the second audible device 520 may be worn on the user's body part (e.g., the left ear or the right ear), and may provide sound information through provided speakers (or receivers). The audible device 500 may be configured to include a processor, an input unit (e.g., a microphone, buttons, or the like), an output unit (e.g., a receiver/speaker), a communication circuit (e.g., a communication module), a storage unit (e.g., a memory), or the like. The audible device 500 may be configured to include a variety of sensors. The sensors, for example, may include a biometric sensor (such as, an HRM (heart rate monitoring) sensor, a gyro sensor, a geomagnetic sensor, a GPS sensor, a body temperature detection sensor, a GSR (galvanic skin response) sensor, an ECG (electrocardiogram) sensor, or a PPG (photoplethysmogram) sensor).
The audible device 500 may include a housing (or a body) 550, and the housing 550, for example, may include a portion that is detachably mounted on the user's ear, a speaker, a battery, a wireless communication circuit, a memory, a processor, or the like.
The audible device 500 may be connected to the electronic device 400 (e.g., a mobile device, a smart phone, a tablet PC, etc.) by wireless communication. For example, in the case of wireless communication, the audible device 500 may process the audio signals (for example, applying an audio filter or amplifying the signal) received through an antenna, and may output sounds through the output unit. The audible device 500 may analyze the input audio signal, and if the input audio signal is determined to be a noise, the audible device 500 may eliminate the input audio signal. If no audio signal of more than a specific value is generated for a specific period of time, the audible device 500 may operate, at least in part, in the low power mode.
The audible device 500 may change the role of a master or a slave based on the connection with the electronic device 400 in order to reduce the battery consumption difference. The audible device 500 may perform the role conversion depending on the battery level, and may seamlessly perform the works through the exchange for the allocated works (e.g., the works requiring the current consumption of the audible device 500) upon the role conversion. The audible device 500 may seamlessly adjust the works between the first audible device 510 and the second audible device 520 in consideration of the battery level and the wearing state in order to thereby effectively operate the battery life and in order to thereby allow one audible device to process the works of the other audible device so that the usability may increase.
The audible device 500 may detect the battery level of each audible device, and may detect whether or not the user is wearing the corresponding audible device 500 by using various sensors (e.g., an HRM (heart rate monitoring) sensor, an acceleration sensor, etc). the audible device 500 may perform wireless communication between the first audible device 510 and the second audible device 520 based on wireless communication (e.g., Bluetooth communication, BLE communication, etc.), or one (e.g., a master) of the first audible device 510 or the second audible device 520 may communicate with the electronic device 400. The audible device 500 may seamlessly exchange the works between the first audible device 510 and the second audible device 520 by determining the battery level and the wearing state.
The work distribution of the audible device 500 may include the work distribution based on the battery ratio or the work distribution depending on the usage. For example, the work distribution of the audible device 500 may be performed in the case where the workload ratio can be adjusted to be closer (or approximate) to the battery ratio in the work distribution determination cycle or in the case where either of the audible devices cannot be used (e.g., taking-off or power-off). The workload may be expressed by the current consumption for the corresponding operation in the battery measurement cycle. When the work distribution determination cycle may be expressed by the time for which the battery 1 is consumed when the work having a minimum workload is independently executed on the assumption that the total amount of the battery is expressed to be 100. A work distribution method according to the battery ratio or the usage will be described in detail with reference to the drawings illustrated below.
The first audible device 510 and the second audible device 520 of the audible device 500 may be charged (e.g., wired charging or wireless charging) by interworking with the charging device 600. For example, when the audible device 500 is placed on the charging device 600, the audible device 500 may perform the charging operation based on the voltage supplied from the charging device 600. The audible device 500 may be applied with power, which is transmitted through an electrical circuit from the charging device 600, through an electrical circuit, and may charge the internal battery based on the applied power.
The audible device 500 may exchange information (e.g., power information) on the charging power (e.g., the charging voltage and the charging current) with the charging device 600 by using communication. For example, the audible device 500 and the charging device 600 may perform communication for the transmission and reception of information through each electrical circuit. Alternatively, the audible device 500 and the charging device 600 may perform communication for the transmission and reception of information through short-range communication (e.g., BLE, Zigbee, NFMI, NFC, etc.).
The audible device 500 may selectively receive at least one of a plurality of charging powers from the charging device 600. The audible device 500 may process the battery charging by using at least one charging power, which is selected. For example, the audible device 500 may receive the first charging power (e.g., a normal charging power) from the charging device 600, and may perform the charging to correspond to the first charging power, which has been received. The audible device 500 may make a request to the charging device 600 for the second charging power (e.g., a high-speed charging power) that is greater than the first charging power, which is used for the normal charging, through communication with the charging device 600. Accordingly, the audible device 500 may be supplied with power corresponding to the second charging power from the charging device 600. The audible device 500 may perform high-speed charging by using the second charging power supplied from the charging device 600. If the second charging power, which has been requested, is not supplied, the audible device 500 may perform the normal charging by using the power (e.g., the first charging power) supplied from the charging device 600.
The audible device 500 may include a PMIC, a charger IC, or the like. For example, the PMIC may be mounted in an integrated circuit or a SoC semiconductor. The PMIC may include a charger IC. The charge IC may include a charger IC for the wireless charging method. The wireless charging method, for example, may include an electromagnetic resonance method, a magnetic induction method, or an electromagnetic wave method, and additional circuits for the wireless charging (such as a coil loop, a resonance circuit, or a rectifier) may be added.
The audible device 500 may include a battery, and the battery may be charged through a separate charging device 600 (e.g., a battery charging dock or a cradle). The battery of the audible device 500 may be charged by directly receiving the output power of a power supply device (e.g., a travel adapter (TA) or a power supply).
The charging device 600 may include one or more batteries, and may include a charging circuit for charging the audible device 500 (e.g., the first audible device 510 or the second audible device 520). The charging device 600 may be configured to include a coil for wireless charging. When the direct current (DC) power is supplied from the power supply device (e.g., a travel adapter (TA) or a power supply), the charging device 600 may convert the DC power into the alternating current (AC) power, and may transmit the power to the audible device 500 through an electrical circuit (e.g., a charging terminal or a transmission coil for wireless charging). The power supply device may be integrally included in the charging device 600, or may be implemented to be a separate device (e.g., a charger).
The charging device 600 may include a housing (or a body) 650, and the housing 650, for example, may include a communication circuit, a power interface, a control circuit, a battery, and at least one coupling recess (e.g., a fixing member) that is configured to accept the audible device 500.
The charging device 600 may control the power supply device to supply the first voltage (e.g., a reference voltage of 5V) or the second voltage (e.g., a high voltage of 10V), which is greater than the first voltage (e.g., the reference voltage of 5V). For example, if the charging device 600 detects the connection of the power supply device, the charging device 600 may control the power supply device to output the first voltage, and thereafter, may control the power supply device to output the second voltage in response to a request of the audible device 500. The charging device 600 may control the power supply device to gradually change the maximum voltage to a low voltage to then be supplied. For example, when a connection of the power supply device is detected, the charging device 600 may control the power supply device to output the second voltage (e.g., the maximum voltage of 10V), and thereafter, may control the power supply device to output the third voltage (e.g., 7V), which is lower than the second voltage, in response to a request of the audible device 500. The third voltage may be greater than the first voltage and may be less than the second voltage. The charging device 600 may output the output power of the power supply device based on information (e.g., power information) related to the charging power (e.g., the charging voltage and the charging current) that is required by the audible device 500.
The charging device 600 may configure a high-speed charging mode or a normal charging mode depending on whether or not the power supply device supports the high-speed charging. The charging device 600 may receive a variety of information about the ID of the power supply device or the type thereof from the power supply device. The charging device 600 may determine whether or not the power supply device supports the high-speed charging mode by using the received information. If the power supply device supports the high-speed charging mode, the charging device 600 may configure the charging mode to be the high-speed charging mode.
The charging device 600 may receive a request for the second charging power greater than the first charging power through communication with the audible device 500. The charging device 600 may transfer the second charging power to the power supply device through communication with the power supply device, and may control the power supply device to supply the second charging power. For example, the charging device 600 may make a control to make a request to the power supply device for the output voltage that is greater than the normal charging power for the audible device 500 and to receive the output voltage that is greater than the normal charging power from the power supply device.
As shown in
The electronic device 400 and the first audible device 510 may be connected with each other through the first wireless communication, and the first audible device 510 and the second audible device 520 may be connected with each other through the second wireless communication. The first wireless communication and the second wireless communication may be implemented by the same communication scheme, or by different communication schemes.
The electronic device 400 may operate as a mater device for the audio streaming between the electronic device 400 and the first audible device 510, and may transmit the audio streaming reproduced by the electronic device 400 to the first audible device 510.
The first audible device 510 may operate as a slave device for the electronic device 400, and may operate as a master device for the second audible device 520. The first audible device 510 may receive the audio streaming (e.g., the first audio streaming for the first audible device 510 or the second audio streaming for the second audible device 520) through the first wireless communication from the electronic device 400. The first audible device 510 may output the received audio streaming (e.g., the first audio streaming for the first audible device 510) through the speaker. In addition to the output of the audio streaming, the first audible device 510 may transmit the audio streaming (e.g., the second audio streaming for the second audible device 520) to the second audible device 520 through the second wireless communication.
The second audible device 520 may operate as a slave device for the first audible device 510. The second audible device 520 may receive the audio streaming (e.g., the second audio streaming for the second audible device 520) through the second wireless communication from the first audible device 510. The second audible device 520 may output the received audio streaming (e.g., the second audio streaming for the second audible device 520) through the speaker.
In the operating state as shown in
The audible device 500 may identify the first state information of the first audible device 510 and the second state information of the second audible device 520 in order to thereby change the role of a master between the first audible device 510 and the second audible device 520. For example, if the first battery level of the first audible device 510 is greater than the second battery level of the second audible device 520 while both the first audible device 510 and the second audible device 520 are worn on the ears, the first audible device 510 having the first battery level may be determined to be a master device in order to thereby maintain the role of a master. As another example, if the first battery level of the first audible device 510 is less than the second battery level of the second audible device 520 while both the first audible device 510 and the second audible device 520 are worn on the ears, the second audible device 520 may be determined to be a master device in order to thereby change the role of a master/slave. As another example, if the first audible device 510 is worn but the second audible device 520 is not worn, or if the battery level of the second audible device 520 is equal to, or less than, a specific level (or the power is expected to be turned off), the first audible device 510 may remain to be the role of a master, and may further perform the works that are allocated to the second audible device 520. As another example, if the second audible device 520 is worn but the first audible device 510 is not worn, or if the battery level of the first audible device 510 is equal to, or less than, a specific level (or the power is expected to be turned off), the role of a master may be changed such that the second audible device 520 is determined to be a master device and the works, which have been allocated to the first audible device 510, may be distributed to the second audible device 520.
In the operating state as shown in
If the first battery level is higher than the second battery level, the electronic device 400 may determine the first audible device 510 having the first battery level to be a master device, and may maintain the connection with the first audible device 510. If the second battery level is higher than the first battery level, the electronic device 400 may determine the second audible device 520 of the second battery level to be a master device, and may determine to change the connection of the audible device 500. The electronic device 400 may process the operation that is related to the execution of a connection with the second audible device 520. For example, the electronic device 400 may process a signal communication operation for a connection (e.g., pairing) with the second audible device 520 based on the first wireless communication. The electronic device 400 may provide a control signal that allows the second audible device 520 to operate as a master in the signal communication operation. When the electronic device 400 switches the connection from the first audible device 510 to the second audible device 520, the electronic device 400 may perform an operation of releasing the connection with the first audible device 510. The electronic device 400 may instruct to configure a connection with the second audible device 520 through the first audible device 510, and may process an intermediate operation (or a relay operation) in order for the first audible device 510 to configure a connection between the electronic device 400 and the second audible device 520 (for example, an operation of transferring a control signal of the electronic device 400).
In the operating state as shown in
If the first battery level is higher than the second battery level, the first audible device 510 may be determined to be a master device so that the current role thereof may be maintained. The first audible device 510 may provide the electronic device 400 with information on the determination of the master device.
If the second battery level is higher than the first battery level, the first audible device 510 may determine the second audible device 520 to be a master device, and may determine the role change (for example, a master a slave). The first audible device 510 may process the operations that are related to the role change from the master device to the slave device. For example, the first audible device 510 may process the signal communication operation to allow the second audible device 520 to operate as a master device based on the second wireless communication. The first audible device 510 may provide information to allow the second audible device 520 to configure communication with the first audible device 510 based on the first wireless communication in the signal communication operation with the second audible device 520. The first audible device 510 may control the second audible device 520 to operate as a master and may perform an operation of releasing the connection with the electronic device 400 when changing the role thereof. The first audible device 510 may provide information to allow the electronic device 400 to configure a connection with the second audible device 520 through the first wireless communication.
In addition to the role change, the first audible device 510 and the second audible device 520 may exchange, or redistribute, the works, which have been allocated (distributed) to the respective audible devices 510 and 520. For example, Work 1 that has been allocated to the first audible device 510 may be distributed to the second audible device 520 in order for the second audible device 520 to perform the operation related thereto, and Work 2 that has been allocated to the second audible device 520 may be distributed to the first audible device 510 in order for the first audible device 510 to perform the operation related thereto. The dynamic work distribution, will be described in detail with reference to the drawings illustrated below.

As shown in
In addition to the role change, the first audible device 510 and the second audible device 520 may exchange, or redistribute, the works, which have been allocated (distributed) to the respective audible devices 510 and 520. For example, when the role of the first audible device 510 is changed due to taking-off or the expectation of power-off, Work 1, which has been allocated to the first audible device 510, may be distributed to the second audible device 520 in order for the second audible device 520 to perform the operations related thereto. The second audible device 520 may operate to process Work 1 as well as previously allocated Work 2. The dynamic work distribution, according to various embodiments, will be described in detail with reference to the drawings illustrated below.

Hereinafter, in various embodiments, the dynamic work distribution, according to the state of the audible device 500, will be described.
Referring to
The step of creating the work distribution combination table (1110) may include obtaining and creating all work distribution combinations that can be operated between the first audible device 510 and the second audible device 520 or the battery consumption rates corresponding to the work distribution combinations.
The step of monitoring (1120) may include periodically checking the battery ratio and determining the work redistribution if there is a more suitable combination than the current battery ratio of each audible device 510 or 520, or if the counterpart audible device is not available.
The step of redistributing works (1130) may include redistributing works between the first audible device 510 and the second audible device 520 through an appropriate protocol according to the work redistribution combination when the work redistribution is determined.
Hereinafter, the steps of redistributing works of the audible device, according to various embodiments, will be described in detail.
The works may include a work that consumes the current in the first audible device 510 and the second audible device 520. The workload may include the current that is consumed for the corresponding operation in the battery determination (measurement) cycle. The work distribution determination cycle may be expressed by the time in which the battery 1 is consumed when the work having the minimum workload is independently executed on the assumption that the total amount of the battery is 100.
The classification of the works of the audible device 500 may be shown as illustrated in Table 1 below.
The work distribution may be performed if the workload ratio can be adjusted to be closer to the battery ratio in the work distribution determination cycle, or if one of the audible devices is not available (e.g., taking-off or power-off).
Hereinafter, the work distribution based on the battery ratio will be described.
The workload ratio that is closer to the battery ratio will be described. Table 2 below may represent the example of the works allocated to the audible device 500.
The works may be classified into undistributable works (e.g., works fixed to the first audible device 510 and the second audible device 520), distributable works, and exchangeable works. The fixed works, for example, may refer to works (L Dedicated works or R Dedicated works) that are fixed to the left audible device (e.g., the first audible device 510 or the L piece) and the right audible device (e.g., the second audible device 520 or the R piece) in Table 2. The distributable works may represent works for sensors or music in Table 2. The exchangeable works may represent master works or slave works in Table 2.
The work distribution, for example, may be made by eight combinations between the first audible device 510 and the second audible device 520, including the fixed works, as shown in Table 3, and the workload ratio of the first audible device 510 and the second audible device 520 may be calculated.
The work distribution may be performed to distribute the work in which each audible device has a closest R/L workload ratio to the current battery R/L ratio (e.g., the battery ratio of each of the first audible device 510 and the second audible device 520) in the battery measurement cycle. For example, referring to Table 3, on the assumption that the current battery R/L ratio is 3.0, the works may be redistributed according to Combination 2 that has the closest value in Table 3.
The steps of applying the work distribution method described above may be performed as follows.
Provided that the first audible device 510 (e.g., the L piece) and the second audible device 520 (e.g., the R piece) have the same amount of battery, which is 100, the workload distribution may be dynamically performed as shown in Table 4 below so that the first audible device 510 and the second audible device 520 operate until Timeline 11. Table 4 below may show an example of the dynamic work distribution method when the amount of battery of each of the first audible device 510 and the second audible device 520 is 100 in various embodiments.
On the contrary, in the case where the sensor work is fixed to the first audible device 510 (e.g., the L piece) and the music work is fixed to the second audible device 520 (e.g., the R piece), the first audible device 510 and the second audible device 520 may operate until Timeline 10. Table 5 below may show an example of a fixed work method when the amount of battery of each of the first audible device 510 and the second audible device 520 is 100.
If the battery difference between the first audible device 510 and the second audible device 520 significantly increases, the difference of the usage time may become greater. For example, if it is assumed that the operation is initiated in the state in which the battery amount of the first audible device 510 (e.g., the L piece) is 100 and the battery amount of the second audible device 520 (e.g., the R piece) is 40, the audible devices may operate until Timeline 7, as shown in Table 6 below, in the case of using the dynamic work distribution method, according to various embodiments, whereas the audible devices may operate until Timeline 4, as shown in Table 7 below, in the case of using the fixed work method. Table 6 and Table 7 below may show an example of the dynamic work distribution method (Table 6) and the fixed work method (Table 7) when the battery amount of the first audible device 510 (e.g., the L piece) is 100 and the battery amount of the second audible device 520 (e.g., the R piece) is 40.
Hereinafter, the work distribution according to the wearing (usage) state will be described.
In the case where the workload is fixedly distributed (for example, the reproduction of music is fixed to the first audible device 510 (e.g., the L piece) and the sensor work is fixed to the second audible device 520 (e.g., the R piece)), if the user, for example, exercises while wearing only the second audible device 520, sensor data cannot be obtained so that an exercise coaching function is not available. In addition, if either of the audible devices is discharged first, the function that is fixed to the corresponding audible device is not available.
The availability of the audible device 500 is determined in order to dynamically distribute the works to the available audible device. Therefore, even though the user uses only one of the audible devices, the functions can be used without dependency on the hardware. This will be described with reference to
If the audible device 500 determines that the user uses only one of the audible devices, the audible device 500 may transfer the work of the audible device, which is not in use, to the available audible device in order to thereby allow the available audible device to perform the work of the other audible device.
Referring to the illustration of
The load balancer 1230 may receive the related state information based on at least one of the in-ear detector 1210 or the power manager 1220, and may determine whether or not the first audible device 510 is in use while being worn on the user or whether or not the first audible device 510 is expected to be turned off due to a low battery based on the related state information.
If the load balancer 1230 determines that the first audible device 510 is not in use by the user (that is, the first audible device 510 is not worn on the user) through the in-ear detector 1210, or if the load balancer 1230 determines that the first audible device 510 is expected to be turned off through the power manager 1220, the load balancer 1230 may distribute the works of the first audible device 510 to the second audible device 520. For example, in various embodiments, in the case where the user takes off the first audible device 510, or in the case of a low battery, distributable works may be transferred to the other audible device so that the other audible device may perform the related works.
Referring to
In the description above, the timing and criteria for the work distribution have been described. Hereinafter, the description will be made of a sequence in which the works are distributed.
The work distribution may be differently processed depending on whether or not the work is related to the connection with the electronic device 400, and thus, the works may be classified into two types as the example shown in Table 8.
Currently, most audible devices provide a function of receiving music data by means of streaming through a Bluetooth connection with the electronic device 400 and reproducing the same. In this case, the roles of a master and a slave of the audible devices may be shown as the example of Table 9 below.
As shown in Table 9, the works to be exchanged by the audible devices may include the master/slave roles. Due to this, a method is required, which can seamlessly change the connection with the electronic device 400 in order to not discontinue the reproduction of the sound source during the work exchange between the audible devices.
Hereinafter, according to various embodiments, the step of exchanging works between the first audible device 510 and the second audible device 520 will be described in consideration of the works that are related to the connection between the audible device 500 and the electronic device 400 and the works that are not related to the same (for example, depending on the battery difference during the streaming) with reference to
In
The transfer of the battery state information (e.g., the battery level) may be perform by a slave device in the case where the electronic device 400 is connected with a master device, or may be performed by the audible device, of which the battery level is high, in the case where the electronic device 400 is not connected. For example, in various embodiments, the priority for transferring the battery state information may be given to the slave audible device, or may be given to the audible device that has a high battery level depending on the connection or non-connection with the electronic device 400. Since a master device takes lead in the work distribution when the electronic device 400 is connected, it may be preferable to receive the battery state information from a slave device. In addition, in the case where the electronic device 400 is not connected, the audible device, which has a higher battery level, may play the role of transferring the battery state.
Referring to
In step 1303, the first audible device 510 may determine whether or not the work redistribution is to be made. The audible device may determine the work redistribution when the adjustment of the workload ratio is required according to the work distribution determination cycle or one of the audible devices is not available (e.g., taking-off or power-off). For example, the load balancer of the first audible device 510 may determine the workload ratio according to the battery ratio of the first audible device 510 to the second audible device 520, and may determine the work distribution according to the result thereof.
The first audible device 510 may compare the second battery level of the second audible device 520 with battery state information of the first audible device 510 (hereinafter, the first battery level). The first audible device 510 may determine the work distribution based on the comparison result. For example, as described above, the first audible device 510 may distribute the work that has the closest R/L workload ratio of each audible device to the battery ratio of each of the first audible device 510 and the second audible device 520. For example, the load balancer of the first audible device 510 may determine the work distribution from the master role and Work 1 to the slave role and Work 2 with respect to the first audible device 510, and may determine the work distribution from the slave role and Work 2 to the master role and Work 1 with respect to the second audible device 520.
In step 1305, the first audible device 510 may transmit, to the second audible device 520, a notification of work redistribution initiation, which contains work redistribution information.
In step 1310 (e.g., step 1307 to step 1323), the first audible device 510, the second audible device 520, and the electronic device 400 may perform the operation for exchanging the connection-related works.
In step 1307, the first audible device 510 may transmit a master/slave conversion command to the electronic device 400. The first audible device 510 may include information on the time required for the master/slave conversion (e.g., the conversion time) in the same to then be transmitted.
In step 1309, the electronic device 400 may transmit, to the first audible device 510, buffering sound source data in consideration of the conversion time of the first audible device 510 from the master to the slave. For example, the electronic device 400 may transmit, to the first audible device 510, the buffering sound source data in order to seamlessly reproduce the same during the master/slave conversion time of the first audible device 510. The buffering sound source data may contain the first sound source data for the first audible device 510 and the second sound source data for the second audible device 520.
In step 1311, the first audible device 510 may transmit the master/slave conversion command to the second audible device 520.
In step 1313, the first audible device 510 may transmit the buffering sound source data to the second audible device 520 sequentially or in parallel to the conversion command. For example, the first audible device 510 may transmit, to the second audible device 520, the buffering sound source data (e.g., the second sound source data) in consideration of the master/slave conversion time.
In step 1315, the first audible device 510 may transmit, to the electronic device 400, connection information by which the electronic device 400 may connect to the second audible device 520. The first audible device 510 may transmit, to the electronic device 400, connection information, such as the MAC address and/or security information of the second audible device 520, through out of band (00B). The first audible device 510 and the second audible device 520 may recognize the connection information between them in the course of the pairing between a master and a slave, and the electronic device 400 may cache the connection information to then reuse the same in the next conversion operation.
In step 1317, in response to the reception of the connection information of the second audible device 520 from the first audible device 510, the electronic device 400 may perform a direct pairing with the second audible device 520 based on the received connection information.
In step 1319, the first audible device 510 may notify the electronic device 400 that the preparation for the role conversion is completed, and may disconnect from the electronic device 400. The step 1319 may be performed prior, or in parallel, to operation 1317.
In step 1321 and step 1323, the first audible device 510 and the second audible device 520 may change roles. For example, the first audible device 510 may change the role from a master to a slave in step 1321, and the second audible device 520 may change the role from a slave to a master in step 1323. The first audible device 510 and the second audible device 520 may maintain the works (e.g., Work 1 and Work 2) that were previously configured when changing the roles.
In step 1330 (e.g., step 1331 to step 1339), the first audible device 510 and the second audible device 520 may perform the operation of distributing works that are not related to the connection.
In step 1331, the first audible device 510 may transmit, to the second audible device 520, Work 1 and information related thereto. For example, the first audible device 510 may transmit, to the second audible device 520, Work 1, which has been distributed to the first audible device 510, and the context (e.g., status information) for resuming Work 1 in the second audible device 520. Provided that Work 1 of the first audible device 510 is a work related to the sensor operation, the first audible device 510 may provide the second audible device 520 with a command to perform the work for the sensor operation and the context related to currently measured health information (e.g., the accumulated distance, calories, or steps) in order for the second audible device 520 to continuously perform the work for the sensor operation.
In step 1333, the second audible device 520 may transmit, to the first audible device 510, Work 2 and information related thereto. For example, the second audible device 520 may transmit, to the first audible device 510, Work 2, which has been distributed to the second audible device 520, and the context (e.g., status information) for resuming Work 2 in the first audible device 510.
In step 1335 and step 1337, the first audible device 510 and the second audible device 520 may perform the work redistribution. For example, the first audible device 510 may change the operation work from Work 1 to Work 2 in step 1335, and the second audible device 520 may change the operation work from Work 2 to Work 1 in step 1337.
In step 1339, the first audible device 510 may transmit a notification of work redistribution termination to the second audible device 520. For example, in response to the reception of Work 2 and the context from the second audible device 520, and in response to the work redistribution completion thereof, the first audible device 510 may identify whether or not the work redistribution by the first audible device 510 and the second audible device 520 is completed. The first audible device 510 may notify the second audible device 520 of the work redistribution termination when determining the work redistribution completion.
Referring to
In step 1403, the second audible device 520 may determine whether or not the work redistribution is to be made. The audible device may determine the work redistribution when the adjustment of the workload ratio is required according to the work distribution determination cycle or one of the audible devices is not available (e.g., taking-off, a low battery, or power-off). For example, the load balancer of the first audible device 510 may expect that the power will be turned off due to a low battery, and may determine the work distribution according to the result thereof.
In step 1405, the second audible device 520 may transmit, to the first audible device 510, a notification of work redistribution initiation, which contains work redistribution information.
In step 1410 (e.g., step 1407 to step 1421), the first audible device 510, the second audible device 520, and the electronic device 400 may perform the operation for exchanging the connection-related works.
In step 1407, the first audible device 510 may transmit a master/slave conversion command (e.g., a request for connection conversion into the second audible device 520) to the electronic device 400. The first audible device 510 may include information on the time required for the master/slave conversion (e.g., the conversion time) in the same to then be transmitted.
In step 1409, the electronic device 400 may transmit, to the first audible device 510, buffering sound source data in consideration of the conversion time of the first audible device 510 from a master to a slave. For example, the electronic device 400 may transmit, to the first audible device 510, the buffering sound source data in order to seamlessly reproduce the same during the master/slave conversion time of the first audible device 510. The buffering sound source data may contain the first sound source data for the first audible device 510 and the second sound source data for the second audible device 520.
In step 1411, the first audible device 510 may transmit the buffering sound source data to the second audible device 520. For example, the first audible device 510 may transmit, to the second audible device 520, the buffering sound source data (e.g., the second sound source data) in consideration of the master/slave conversion time.
In step 1413, the first audible device 510 may transmit, to the electronic device 400, connection information by which the electronic device 400 connects to the second audible device 520. The first audible device 510 may transmit, to the electronic device 400, connection information, such as the MAC address and/or security information of the second audible device 520, through OOB. The first audible device 510 and the second audible device 520 may recognize the connection information between them in the course of the pairing between a master and a slave, and the electronic device 400 may cache the connection information to then reuse the same in the next conversion operation.
In step 1415, in response to the reception of the connection information of the second audible device 520 from the first audible device 510, the electronic device 400 may perform a direct pairing with the second audible device 520 based on the received connection information.
In step 1417, the first audible device 510 may notify the electronic device 400 that the preparation for the role conversion is completed, and may disconnect from the electronic device 400. Step 1417 may be performed prior, or in parallel, to step 1415.
In step 1419 and step 1421, the first audible device 510 and the second audible device 520 may change roles. For example, the first audible device 510 may change the role from a master to a slave in step 1419, and the second audible device 520 may change the role from a slave to a master in step 1421. The first audible device 510 and the second audible device 520 may maintain the works (e.g., Work 1 and Work 2) that were previously configured when changing roles.
In step 1430 (e.g., step 1431 to step 1437), the first audible device 510 and the second audible device 520 may perform the operation of distributing works that are not related to the connection.
In step 1431, the first audible device 510 may transmit, to the second audible device 520, Work 1 and information related thereto. For example, the first audible device 510 may transmit, to the second audible device 520, Work 1, which has been distributed to the first audible device 510, and the context (e.g., status information) for resuming Work 1 in the second audible device 520. Provided that Work 1 of the first audible device 510 is a work related to the sensor operation, the first audible device 510 may provide the second audible device 520 with a command to perform the work for the sensor operation and the context related to currently measured health information (e.g., an accumulated distance, calories, or steps) in order for the second audible device 520 to continuously perform the work for the sensor operation.
In step 1433 and step 1435, the first audible device 510 and the second audible device 520 may perform the work redistribution. For example, the first audible device 510 may have no work to be executed therein according to the work redistribution in step 1433, and the second audible device 520 may have Work 2, which has been redistributed, in addition to existing Work 1 according to the work redistribution in step 1435. For example, the second audible device 520 may process all works related to Work 1 and Work 2 sequentially, periodically, or in parallel.
In step 1437, the second audible device 520 may transmit a notification of work redistribution termination to the first audible device 510. For example, in response to the reception of Work 1 and the context from the first audible device 510, and in response to the work redistribution completion thereof, the second audible device 520 may identify whether or not the work redistribution by the first audible device 510 and the second audible device 520 is completed. The second audible device 520 may notify the first audible device 510 of the work redistribution termination when determining the work redistribution completion.
In the case where the audible device 500 is not connected with the electronic device 400, the audible device 500 may omit the operation for the connection-related work distribution between the first audible device 510 and the second audible device 520, and may perform the operation for connection-unrelated work distribution in the embodiments of
Referring to
In step 1503, the controller 880 may obtain data. The controller 880 may perform an operation that is related to the acquisition of the data to correspond to the work distribution (measurement) determination cycle. The data may contain the first data that is related to the first audible device 510 and the second data that is related to the second audible device 520. The first data may contain data related to state information (e.g., the battery level of the first audible device 510 (e.g., the remaining amount of the battery included in the first audible device 510, hereinafter, referred to as the first battery level)), wearing information, or taking-off information of the first audible device 510. The second data may contain data related to state information (e.g., the battery level of the second audible device 520 (e.g., the remaining amount of battery included in the second audible device 520, hereinafter, referred to as the second battery level)), wearing information, or taking-off information of the second audible device 520.
In step 1503, the controller 970 may determine the state of the audible device 500 (e.g., the first audible device 510 or the second audible device 520) based on the first data and the second data, which are obtained. The controller 970 may detect the battery level of the first audible device 510 (e.g., the remaining amount of the first battery included in the first audible device 510, hereinafter referred to as the first battery level) based on the first data, and may detect the battery level of the second audible device 520 (e.g., the remaining amount of the second battery included in the second audible device 520, hereinafter referred to as the second battery level) based on the second data. The controller 970 may determine whether or not the first audible device 510 is in use by the user (e.g., wearing or non-wearing) based on the first data, and may determine whether or not the second audible device 520 is in use by the user (e.g., wearing or non-wearing) based on the second data. The controller 970 may determine whether or not the first audible device 510 is expected to be turned off based on the first data (e.g., the first battery level), and may determine whether or not the second audible device 520 is expected to be turned off based on the second data (e.g., the second battery level). The controller 970 may compare the first battery level with the second battery level, and may determine which battery level is higher among the first battery level or the second battery level based on the comparison result.
In step 1507, the controller 970 may determine whether or not the work redistribution is to be made. When it is determined that the adjustment of the workload ratio between the first audible device 510 and the second audible device 520 is required based on the obtained data, the controller 970 may determine the work redistribution of the first audible device 510 and the second audible device 520. When it is determined that one of the first audible device 510 or the second audible device 520 is not available (e.g., taking-off, a low battery, or power-off) based on the obtained data, the controller 970 may determine the work redistribution of the first audible device 510 and the second audible device 520.
If the work redistribution is not determined in step 1507 (No in step 1507), the controller 970 may proceed to step 1503 in order to thereby process the execution of step 1503 and subsequent operations.
If the work redistribution is determined in step 1507 (Yes in step 1507), the controller 970 may transmit a work redistribution notification to the connected audible device 500 in step 1509. For example, the controller 970 may transmit, to the second audible device 520 connected, a work redistribution notification that includes work redistribution information.
In step 1511, the controller 970 may determine whether or not to change the roles. For example, the controller 970 may determine whether or not the role change between the first audible device 510 and the second audible device 520 is required.
If it is determined that the role change is required in step 1511 (Yes in step 1511), the controller 970 may perform an operation that is related to the connection-related work distribution in step 1513. The controller 970, as described in the example with reference to step 1310 of
In step 1515, the controller 970 may perform an operation that is related to the connection-unrelated work distribution after the role change. The controller 970, as described in the example with reference to step 1330 of
If it is determined that the role change is not required in step 1511 (No in step 1511), the controller 970 may perform the operation that is related to the connection-unrelated work distribution, instead of performing the operation that is related to the connection-related work distribution, in step 1515.
In the case where the audible device 500 is not connected with the electronic device 400, the audible device 500 may not perform the operation that is related to the connection-related work distribution in
When the controller 970 determines the state in which the first audible device 510 is not available (e.g., a low battery) based on the first battery level of the first audible device 510, the controller 970 may transmit a power-off notification of the first audible device 510 to the second audible device 520. In this case, in response to the work redistribution notification of the second audible device 520, the controller 970 may process the execution of the operation that is related to the aforementioned connection-related work and/or connection-unrelated work.
Referring to
In step 1603, the controller 970 may receive data. For example, the controller 970 may receive a power-off notification of the first audible device 510 or a work redistribution notification from the first audible device 510, which is connected.
In step 1605, the controller 970 may determine whether the received data corresponds to the power-off notification or to the work redistribution notification.
If the received data is the power-off notification in step 1605 (Yes in step 1605), the controller 970 may determine whether or not the work redistribution is to be made in step 1607. In response to the reception of the power-off notification from the first audible device 510, which is connected, the controller 970 may determine the state in which the first audible device 510 is not available (e.g., a low battery or power-off) in order to thereby determine the work redistribution of the first audible device 510 and the second audible device 520.
The controller 970 may transmit a work redistribution notification to the connected audible device 500 in step 1609. For example, the controller 970 may transmit, to the first audible device 510 connected, a work redistribution notification that includes work redistribution information.
In step 1611, the controller 970 may perform an operation that is related to the connection-related work distribution. The controller 970, as described in the example with reference to step 1410 of
In step 1613, the controller 970 may perform an operation that is related to the connection-unrelated work distribution after the connection with the electronic device 400 and the role change. The controller 970, as described in the example with reference to step 1430 of
If the received data is not the power-off notification in step 1605 (No in step 1605), the controller 970 may determine whether or not the received data corresponds to the work redistribution notification in step 1615. The controller 970 may receive, from the first audible device 510, the work redistribution notification according to the adjustment of the workload ratio. The controller 970 may receive a non-wearing (e.g., taking-off) notification from the first audible device 510, and, in response to the non-wearing notification, may determine the state in which the first audible device 510 is not available (e.g., taking-off) in order to thereby determine the work redistribution of the first audible device 510 and the second audible device 520.
If the received data is not the work redistribution notification in step 1615 (No in step 1615), the controller 970 may process the execution of the corresponding operation in step 1617. For example, the controller 970 may receive sound source data from the first audible device 510, and may process an operation that is related to the output of the received sound source data through the speaker.
If the received data is the work redistribution notification in step 1615 (Yes in step 1615), the controller 970 may perform an operation that is related to the connection-related work distribution with the first audible device 510 connected and/or an operation that is related to the connection-unrelated work distribution in step 1619.
In the case where the controller 970 is not connected with the electronic device 400, the controller 970 may not perform the operation that is related to the connection-related work distribution in
When the controller 970 determines the state in which the second audible device 520 is not available (e.g., a low battery) based on the second battery level of the second audible device 520, the controller 970 may transmit a power-off notification of the second audible device 520 to the first audible device 510. In this case, in response to the work redistribution notification of the first audible device 510, the controller 970 may process the execution of the operation that is related to the aforementioned connection-related work and/or connection-unrelated work.

The electronic device 400 and the first audible device 510 may be connected with each other by the first wireless communication, and the first audible device 510 and second audible device 520 may be connected with each other by the second wireless communication. In this case, the first audible device 510, which is connected with the electronic device 400 by the first wireless communication, may be a slave device with respect to the electronic device 400, and may be a master device with respect to the second audible device 520, which is connected by the second wireless communication. The second audible device 520, which is not connected with the electronic device 400, may be a slave device with respect to the first audible device 510, which is connected by the second wireless communication.
The master/slave operation between the first audible device 510 and the second audible device 520 of the audible devices 500 may be pre-configured, and the electronic device 400 may establish a connection with the audible device 500, which is configured to be a master, through the first wireless communication. The electronic device 400 may determine the audible device to which the electronic device 400 attempts to connect among the first audible device 510 and the second audible device 520. For example, the electronic device 400 may compare the state information (e.g., the channel state, the signal strength, the battery level, or the wearing state) of the first audible device 510 with the state information (e.g., the channel state, the signal strength, the battery level, or the wearing state) of the second audible device 520, and may determine the audible device that has better state information (e.g., a good channel state, a strong signal strength, a high battery level, or the state in which the audible device is worn) to be a master device in order to thereby attempt to connect thereto.
The first wireless communication and the second wireless communication may be the same communication scheme, or may be different communication schemes. For example, the first wireless communication and the second wireless communication may include wireless communication, such as BT, BLE, or NFMI. The first wireless communication and the second wireless communication are not limited thereto, and may include a variety of other wireless communication schemes, such as WiFi, NFC, ZigBee, UWB, or IrDA.
In step 1703, the controller 880 may obtain data from the connected audible device 500 (e.g., the first audible device 510). The data may contain the first data that is related to the first audible device 510 and the second data that is related to the second audible device 520. The first data may contain data that is related to state information (e.g., the battery level of the first audible device 510 (e.g., the remaining amount of battery included in the first audible device 510, hereinafter, referred to as the first battery level)), wearing information, or taking-off information of the first audible device 510. The second data may contain data that is related to state information (e.g., the battery level of the second audible device 520 (e.g., the remaining amount of battery included in the second audible device 520, hereinafter, referred to as the second battery level)), wearing information, or taking-off information of the second audible device 520.
The controller 880 may obtain the first data and the second data from the first audible device 510 in the case where the electronic device 400 and the first audible device 510 of a master are connected with each other. For example, the first audible device 510 may receive the second data from the second audible device 520, and may provide the electronic device 400 with the first data of the first audible device 510 and the second data of the second audible device 520, which is received from the second audible device 520.
In step 1705, the controller 880 may determine the state of the audible device 500 (e.g., the first audible device 510 or the second audible device 520) based on the first data and the second data, which are obtained.
For example, the controller 880 may determine the first battery level of the first audible device 510 (e.g., the remaining amount of the battery of the first audible device 510) based on the first data, and may determine the second battery level of the second audible device 520 (e.g., the remaining amount of battery of the second audible device 520) based on the second data.
For example, the controller 880 may determine whether or not the first audible device 510 is in use by the user (e.g., wearing or non-wearing) based on the first data, and may determine whether or not the second audible device 520 is in use by the user (e.g., wearing or non-wearing) based on the second data.
For example, the controller 880 may determine whether or not the first audible device 510 is expected to be turned off based on the first data (e.g., the first battery level), and may determine whether or not the second audible device 520 is expected to be turned off based on the second data (e.g., the second battery level). The controller 880 may compare the first battery level with the second battery level, and may determine which battery level is higher among first battery level and the second battery level based on the comparison result.
In step 1707, the controller 880 may determine whether or not the work redistribution is to be made. When it is determined that the adjustment of the workload ratio between the first audible device 510 and the second audible device 520 is required based on the obtained data, the controller 880 may determine the work redistribution of the first audible device 510 and the second audible device 520. When it is determined that one of the first audible device 510 or the second audible device 520 is not available (e.g., taking-off, a low battery, or power-off) based on the obtained data, the controller 880 may determine the work redistribution of the first audible device 510 and the second audible device 520.
If the work redistribution is not determined in step 1707 (No in step 1707), the controller 880 may proceed to step 1703 in order to thereby process the execution of step 1703 and subsequent steps.
If the work redistribution is determined in step 1707 (Yes in step 1707), the controller 970 may redistribute the works that are configured (allocated) to the first audible device 510 and the second audible device 520 in step 1709.
The controller 880 may determine the workload ratio by the battery ratio of the first audible device 510 and the second audible device 520 in order to thereby distribute the works according to the result thereof. For example, the controller 880 may redistribute the works from a master and Work 1 to a slave and Work 2 with respect to the first audible device 510, and may redistribute the works from a slave and Work 2 to a master and Work 1 with respect to the second audible device 520.
If one audible device is expected to be turned off due to a low battery, the controller 880 may redistribute the works of the audible device, which is expected to be turned off, to the other audible device according to the result thereof. For example, if the audible device, which is expected to be turned off, is a master device, the controller 880 may redistribute the master and the works that are allocated to the audible device, which is expected to be turned off, to the other audible device.
In step 1711, the controller 880 may transmit a work redistribution notification to the audible device 500. For example, the controller 880 may transmit, to the first audible device 510 connected, a work redistribution notification that includes information on the work redistribution and/or a master/slave conversion command.
In step 1713, the controller 880 may process the execution of the corresponding step.
If the master role and the slave role of the first audible device 510 and the second audible device 520 are changed, the controller 880 may make a control to: disconnect from the currently connected audible device (e.g., the first audible device 510); connect to the audible device (e.g., the second audible device 520), of which the role has been changed to a master, by means of a direct pairing; and perform the related works based on the connected audible device.
The controller 880 may store connection information for connecting to the first audible device 510 or the second audible device 520, or may obtain the same from the first audible device 510, which is connected. The connection information may contain the MAC addresses and/or security information of the first audible device 510 and the second audible device 520. The controller 880 may recognize the connection information of the audible devices 500 in the course of the pairing the electronic device 400 with the audible devices 500, and the controller 880 may cache the connection information to then reuse the same in the next conversion step.
Referring to
In step 1803, the controller 970 may transmit data to the connected electronic device 400. The controller 970 may transmit, to the electronic device 400, the first data related to the first audible device 510 (e.g., the first battery level, wearing information, or taking-off information of the first audible device 510) and the second data related to the second audible device 520 (e.g., the second battery level, wearing information, or taking-off information of second audible device 520), which is received from the second audible device 520.
The controller 970 may receive control information from the connected electronic device 400 in step 1805, and may determine whether the received control information corresponds to the first control information or the second control information in step 1807. The first control information may contain a work redistribution notification that allows the audible device 500 to perform the dynamic work distribution operation (e.g., the first function). The second control information may contain information that allows the audible device 500 to perform the operation (e.g., the second function) that is instructed by the electronic device 400.
If it is determined that the received control information is the first control information in step 1807 (Yes in step 1807), the controller 970 may process the execution of the corresponding step based on the first control information in step 1809. The controller 970 may process the execution of the step related to the first function in response to the work redistribution notification received from the electronic device 400. The controller 970 may process the execution of the step related to the connection-related work distribution between the first audible device 510 and the second audible device 520 and/or the connection-unrelated work redistribution in response to the work redistribution notification. For example, the controller 970 may process the execution of at least one of the steps of: changing the roles between the first audible device 510 and the second audible device 520 (e.g., a mastera slave); disconnecting from the electronic device 400 according to the role change and establishing a connection with the electronic device 400 by the other audible device; exchanging works; and distributing works.
If it is determined that the received control information is the second control information in step 1807 (No in step 1807), the controller 970 may process the execution of the corresponding steps based on the second control information in step 1811. The controller 970 may process the execution of the step related to the second function in response to the data or commands received from the electronic device 400. The controller 970 may receive, from the electronic device 400, the first audio streaming for the first audible device 510 and the second audio streaming for the second audible device 520. The controller 970 may process the first audio streaming to be output through the speaker, and may process the second audio streaming to be transmitted to the second audible device 520 connected and to then be output through the speaker of the second audible device 520.
As described above, the electronic device 400 or the audible device 500, for example, may perform the dynamic work distribution based on the battery level and the wearing state of the audible device 500. According to an embodiment, it may be assumed that the first battery level of the first audible device 510 is higher than the second battery level of the second audible device 520, and it may be assumed that the first audible device 510 is not worn (e.g., the second audible device 520 is worn) on the user. In this case, even though the battery level of the first audible device 510 is higher than the battery level of the second audible device 520, when the second audible device 520 is worn on the user, the electronic device 400 or the audible device 500 may process the works corresponding to the first audible device 510 to be performed by the second audible device 520. In addition, in the case where the first audible device 510 is a master device, the roles may be changed between the first audible device 510 and the second audible device 520 such that the second audible device 520 may operate as a master device.

In step 1905, the controller 970 may compare the battery ratio and the reference ratio. The controller 970 may compare at least one of a plurality of reference ratios with the battery ratio. A plurality of reference ratios may correspond to the examples described with reference to Table 1 to Table 7 above, and, for example, may correspond to the workload ratios of the first audible device 510 and the second audible device 520.
In step 1907, the controller 970 may determine the operation (e.g., at least one of the role conversion or the work distribution) of the audible device 500. For example, the controller 970 may determine the role conversion and/or the work distribution for at least one of the first audible device 510 or the second audible device 520 based on at least some of the comparison result. The controller 970 may determine a reference ratio that is closest to the battery ratio among the plurality of reference ratios, and may determine the step corresponding to the determined reference ratio.
In step 1909, the controller 970 may control the operation of at least one of the first audible device 510 or the second audible device 520 based at least some of the determination. The controller 970 may operate to convert the role of at least one of the first audible device 510 or the second audible device 520 and to redistribute the works of at least one of the first audible device 510 or the second audible device 520.
Referring to
In step 2003, the controller 970 may determine the state information. For example, the controller 970 may analyze and determine the state of the audible device 500 based on at least some of the first state information related to the first audible device 510 and the second state information related to the second audible device 520.
In step 2005, the controller 970 may determine whether or not taking-off or power-off of at least one of the first audible device 510 or the second audible device 520 is detected based on at least some of the determination result.
If the state of one of the first audible device 510 or the second audible device 520 corresponds to the taking-off state or the power-off expectation state in step 2005 (Yes in step 2005), the controller 970 may determine the operation of at least one of the first audible device 510 or the second audible device 520 based on the usage (wearing) state in step 2007. The controller 970 may convert the roles of the first audible device 510 and the second audible device 520, and may determine the work redistribution such that the works of the audible device, which is taken off or of which the power is expected to be turned off, may be performed by the other audible device.
If the first audible device 510 and the second audible device 520 do not correspond to the taking-off state or the power-off expectation state in step 2005 (No in step 2005), the controller 970 may determine the operation of at least one of the first audible device 510 or the second audible device 520 based on the battery ratio in step 2009. The controller 970 may determine the role conversion and/or the work distribution for at least one of the first audible device 510 or the second audible device 520 based on the battery ratio.
In step 2011, the controller 970 may control the operation that is determined in step 2007 or step 2009. The controller 970 may operate to convert the role of at least one of the first audible device 510 or the second audible device 520 and to redistribute the works of at least one of the first audible device 510 or the second audible device 520.
