Embodiments of this application relate to the field of terminal technologies, and in particular, to a sound channel configuration method, an electronic device, and a system.
With the development of terminal technologies, wireless sound boxes are increasingly popular. An electronic device (like a smart screen or a television) can be connected to one or more sound boxes, and different sound boxes play sounds of different sound channels, to achieve a better sound playing effect. For example, in a sound box system including two sound boxes, one sound box is configured to play audio of a left sound channel of the electronic device, and the other sound box is configured to play audio of a right sound channel of the electronic device, to provide more stereo sound experience for a user.
In a process of establishing a connection between an electronic device and a sound box, a sound channel corresponding to the sound box needs to be configured to complete sound channel configuration, to establish a sound box system of the electronic device. Currently, in a sound channel configuration process, a user needs to manually perform a plurality of operations on the electronic device to provide each sound box with a corresponding sound channel by using a sound box name. However, the user usually cannot determine an actual sound box specifically corresponding to a sound box name displayed on the electronic device. Therefore, the user needs to reconfirm a sound box name recorded on the sound box or in a sound box specification, and perform sound channel configuration after comparison. This is a cumbersome operation process and affects user experience.
To resolve the foregoing technical problem, embodiments of this application provide a sound channel configuration method, an electronic device, and a system. According to the technical solutions provided in embodiments of this application, a first electronic device whose sound channel is to be configured can adaptively perform sound channel configuration based on a sound intensity of a collected first sound and a second sound intensity reported by a second electronic device, thereby simplifying user operations and improving user experience.
To achieve the foregoing technical objective, embodiments of this application provide the following technical solutions.
According to a first aspect, a sound channel configuration method is provided, and is applied to a first electronic device. The method includes: receiving a first operation of a user, where the first operation is used to trigger the first electronic device to perform sound channel configuration; determining a first sound intensity of a first sound based on a sound collected by a first sound collection apparatus of the first electronic device; determining, based on the first sound intensity, a target sound channel in to-be-configured sound channels of the first electronic device; receiving at least one second sound intensity sent by one or more second electronic devices; determining a target device in the second electronic devices based on the at least one second sound intensity; and matching the target sound channel with the target device.
The first operation is, for example, a sound channel configuration operation. The sound channel configuration operation includes, for example, a touch operation (for example, an operation of tapping a control for confirming to start the sound channel configuration) of the user on a display of the first electronic device, a voice operation indicating the sound channel configuration, an operation of inputting a sound channel configuration command by using a physical button on the first electronic device, and an operation of inputting the sound channel configuration command by using a remote control.
In this way, the first electronic device may automatically complete sound channel configuration in response to the sound channel configuration operation of the user. In a sound channel configuration process, the user only needs to complete a simple operation of generating the first sound, does not need to confirm a name of the second electronic device (for example, a wireless sound box), and does not need to perform more operations on the display of the first electronic device. In this way, user operations in the sound channel configuration process are effectively simplified, and user experience is improved.
According to the first aspect, the determining a first sound intensity of a first sound based on a sound collected by a first sound collection apparatus of the first electronic device includes: if a sound feature of the sound collected by the first sound collection apparatus of the first electronic device meets a preset condition, determining that the collected sound is the first sound, and determining the first sound intensity of the first sound, where the sound feature includes one or more of a frequency feature, an amplitude feature, a waveform feature, and a duration feature.
For example, a sound frequency of tapping a sound box by a human knuckle is generally 800 Hz to 1200 Hz. In a sound pickup process, the first electronic device picks up a sound in the frequency range, and obtains a corresponding sound intensity. Further, optionally, the first electronic device may determine whether a feature of the picked-up sound in the frequency range matches a feature (for example, a sound waveform has one or more peaks) of a sound emitted by tapping a sound box by using the human knuckle. If the two features match, the first electronic device determines that the picked-up sound in the frequency range is the sound emitted by tapping the sound box by using the human knuckle, and determines that the sound is indeed a sound generated when the user wants to perform sound channel configuration on the first electronic device and taps the sound box by using the knuckle, and is not an interference sound like a human sound, music, or environmental background noise.
In this way, the first electronic device determines the first sound by using the sound feature, and then performs sound channel configuration by using the first sound, to avoid interference caused to the sound channel configuration process when another sound is collected.
According to the first aspect or any one of the foregoing implementations of the first aspect, the first sound collection apparatus includes M microphones, where M is a positive integer greater than or equal to two. In a case in which the to-be-configured sound channels include a first sound channel and a second sound channel, and the first sound channel or the second sound channel is a left sound channel or a right sound channel, a quantity of the first sounds is two, the target device includes a first target device and a second target device, and the first target device or the second target device is located on a left side of the first electronic device or located on a right side of the first electronic device. The determining, based on the first sound intensity, a target sound channel in to-be-configured sound channels of the first electronic device includes: determining, based on first sound intensities of first sounds collected by the M microphones for a first time, that the to-be-configured sound channel is the first sound channel. The determining a target device in the second electronic devices based on the at least one second sound intensity includes: determining a first target device in the second electronic devices based on at least one second sound intensity received for a first time. The matching the target sound channel with the target device includes: matching the first sound channel with the first target device. The determining, based on the first sound intensity, a target sound channel in to-be-configured sound channels of the first electronic device includes: determining, based on first sound intensities of first sounds collected by the M microphones for a second time, that the to-be-configured sound channel is the second sound channel. The determining a target device in the second electronic devices based on the at least one second sound intensity includes: determining a second target device in the second electronic devices based on at least one second sound intensity received for a second time. The matching the target sound channel with the target device includes: matching the second sound channel with the second target device.
According to the first aspect or any one of the foregoing implementations of the first aspect, the to-be-configured sound channels of the first electronic device include the left sound channel and the right sound channel; and the determining, based on the first sound intensity, a target sound channel in to-be-configured sound channels of the first electronic device includes: if it is determined, based on the first sound intensity, that the first sound comes from the left side or the right side of the first electronic device, determining that the target sound channel is the left sound channel or the right sound channel. The determining a target device in the second electronic devices based on the at least one second sound intensity includes: determining, as the target device, a second electronic device corresponding to a larger second sound intensity in the at least one second sound intensity.
For example, it is assumed that the to-be-configured sound channels of the first electronic device include the left sound channel and the right sound channel, a sound box A is located on the left side of the first electronic device, and a sound box B is located on the right side of the first electronic device. In this case, the sound channel configuration process may include the following steps: The user taps the sound box A by using the knuckle, and the first electronic device collects a tapping sound by using the microphone, to determine the first sound intensity. It is determined, based on the first sound intensity, that a current sound-emitting position is located on the left side of the first electronic device, and a correspondence should be established between a second electronic device at the position and the left sound channel. Then, the first electronic device needs to determine which second electronic device of the sound box A and the sound box B is the second electronic device at the current sound-emitting position. In other words, the sound box A or the sound box B is the first target device or the second target device.
Correspondingly, in a process in which the user taps the sound box A by using the knuckle, the sound box A and the sound box B can also collect the tapping sound by using microphones included in the sound box A and the sound box B. It may be understood that the sound box A is the second electronic device at the sound-emitting position, and the sound box A is closer to the sound-emitting position than the sound box B. Therefore, a sound intensity of the tapping sound collected by the sound box A should be greater than a sound intensity of the tapping sound collected by the sound box B. The sound box A and the sound box B send the sound intensities of the tapping sound collected by the sound box A and the sound box B to the first electronic device, and the first electronic device obtains second sound intensities of the tapping sound collected by the second electronic devices. Therefore, the first electronic device can determine, based on the second sound intensities, whether a to-be-paired second electronic device is specifically the sound box A or the sound box B. For example, if the first electronic device determines that the sound intensity of the tapping sound collected by the sound box A is large, the first electronic device determines that the second electronic device at the current sound-emitting position is the sound box A. Therefore, the first electronic device establishes the correspondence between the sound box A and the left sound channel, to complete left sound channel configuration.
Then, the user may further tap the sound box B by using the knuckle, and the first electronic device and the second electronic devices repeat the foregoing steps, so that the first electronic device can automatically complete right sound channel configuration based on a sound intensity of the tapping sound received by the microphone of the first electronic device and sound intensities that are of the tapping sound received by the second electronic devices and that are sent by the second electronic devices and received by the first electronic device.
In this way, the user can complete sound channel configuration on the first electronic device by using only a simple tapping operation. Operation steps are simple, sound channel configuration efficiency is high, and user experience can be effectively improved.
According to the first aspect or any one of the foregoing implementations of the first aspect, the first sound collection apparatus includes M microphones, where M is a positive integer greater than or equal to two. When a quantity of the to-be-configured sound channels is greater than two, the determining, based on the first sound intensity, a target sound channel in the to-be-configured sound channels of the first electronic device includes: determining, based on a first quantity of the first sound intensities in the first sound intensities, a second quantity of the target sound channels in the to-be-configured sound channels of the first electronic device, where the first quantity is M times the second quantity. The determining a target device in the second electronic devices based on the at least one second sound intensity includes: determining, based on a second sound intensity corresponding to the first quantity of the first sound intensities, a second quantity of the target devices in the second electronic device. The matching the target sound channel with the target device includes: determining, based on the first quantity of the first sound intensities, a correspondence between the second quantity of the target sound channels and the second quantity of the target devices; and matching the second quantity of the target sound channels with the second quantity of the target devices based on the correspondence.
According to the first aspect or any one of the foregoing implementations of the first aspect, the to-be-configured sound channels of the first electronic device include a left front sound channel, a left rear sound channel, a right front sound channel, and a right rear sound channel; and there are a plurality of first sounds. The determining, based on the first sound intensity, a target sound channel in to-be-configured sound channels of the first electronic device includes: if it is determined, based on the first sound intensity, that the first sound comes from a left side of the first electronic device, determining that the target sound channel is the left front sound channel or the left rear sound channel; or if it is determined, based on the first sound intensity, that the first sound comes from a right side of the first electronic device, determining that the target sound channel is the right front sound channel or the right rear sound channel. The determining a target device in the second electronic devices based on the at least one second sound intensity includes: determining, for each first sound, a second electronic device corresponding to a larger second sound intensity in second sound intensities corresponding to each first sound as a candidate target device, where a quantity of candidate target devices is equal to a quantity of the first sounds; for first sound intensities corresponding to a same sound collection apparatus in first sound intensities that correspond to the first sounds from the left side of the first electronic device, determining a candidate target device corresponding to a larger first sound intensity as a target device corresponding to the left front sound channel, and determining a candidate target device corresponding to a smaller first sound intensity as a target device corresponding to the left rear sound channel; and for first sound intensities corresponding to a same sound collection apparatus in first sound intensities that correspond to the first sounds from the right side of the first electronic device, determining a candidate target device corresponding to a larger first sound intensity as a target device corresponding to the right front sound channel, and determining a candidate target device corresponding to a smaller first sound intensity as a target device corresponding to the right rear sound channel.
In some embodiments, if the quantity of the to-be-configured channels of the first electronic device is greater than two, in a sound box system in which there are two or more second electronic devices in each direction of corresponding directions on two sides of a central axis of the first electronic device, because the microphone of the first electronic device is generally located at corresponding positions on the two sides of the central axis of the first electronic device or located at corresponding positions on the central axis, the first electronic device cannot directly determine the to-be-configured sound channel based on the first sound intensity collected by the microphone at one time, and needs to wait until collection of some or all of the first sound intensities is completed, so that the to-be-configured sound channel can be determined. The some of the first sound intensities include all first sound intensities corresponding to a one-side direction of the central axis of the first electronic device.
For example, the first electronic device is a four-channel surround device, that is, the first electronic device may output four-channel audio, and needs to establish a pairing relationship with four second electronic devices. However, the first electronic device is configured with only two microphones, and the first electronic device cannot distinguish between the left front sound channel and the left rear sound channel or distinguish between the right front sound channel and the right rear sound channel based on first sound intensities collected by the two microphones at one time. Therefore, the first electronic device can further confirm the to-be-configured sound channels only after obtaining all first sound intensities corresponding to the left side of the first electronic device, or all first sound intensities corresponding to the right side of the first electronic device, or all first sound intensities.
In this way, in a multi-channel scenario in which a quantity of the to-be-configured sound channels is greater than two, the user may also complete sound channel configuration on the first electronic device by using a simple tapping operation. Operation steps are simple, sound channel configuration efficiency is high, and user experience can be effectively improved.
According to the first aspect or any one of the foregoing implementations of the first aspect, a sound-emitting position of the first sound includes a first position of the target device or a second position near the target device.
In some embodiments, the first sound intensity includes, for example, a sound intensity of a sound that corresponds to a position of the second electronic device and that is collected by the first electronic device by using a microphone of the first electronic device. A sound corresponding to the position of the wireless sound box may further include a sound generated at or near the position of the wireless sound box, for example, a sound generated when the user beats the wireless sound box, a sound generated when the user makes a finger, claps, or coughs near the wireless sound box, and audio played by the wireless sound box. A position near the second electronic device indicates that a sound generating position is near the position of the second electronic device, for example, a distance between the sound generating position and the position of the second electronic device is less than or equal to a preset threshold. For example, the user may tap the sound box A by using the knuckle, or may make a sound at a position near the sound box A and away from another sound box.
In this way, a sound is generated at the position of the wireless sound box or at a position near the position of the wireless sound box, so that a sound intensity of the sound collected by the wireless sound box is largest, and the wireless sound box is positioned by using the sound intensity of the sound.
According to the first aspect or any one of the foregoing implementations of the first aspect, after the receiving a first operation of a user, the method further includes: obtaining a first Bluetooth name of the second electronic device; and the receiving at least one second sound intensity sent by one or more second electronic devices includes: obtaining a second Bluetooth name of the second electronic device; and determining the at least one second sound intensity based on a newly-added suffix of the second Bluetooth name compared with the first Bluetooth name.
In some embodiments, after enabling a Bluetooth function, the first electronic device can scan for a nearby device that has enabled Bluetooth and is in a to-be-paired state, and obtain a Bluetooth ID of the device. For example, in a Bluetooth scanning process, the first electronic device can obtain a Bluetooth ID list that includes a Bluetooth ID of the second electronic device.
In some embodiments, after the second electronic device edits the Bluetooth ID based on the second sound intensity, in a process of scanning for the nearby device that has enabled Bluetooth and is in the to-be-paired state, the first electronic device can obtain a Bluetooth ID edited by the second electronic device. In other words, the second electronic device sends the edited Bluetooth ID to the first electronic device, so that the first electronic device determines the second sound intensity based on a second Bluetooth ID. In this case, in the Bluetooth scanning process, if the first electronic device finds that some or all Bluetooth ID suffixes in the Bluetooth ID list obtained through scanning change, the first electronic device determines a Bluetooth device whose Bluetooth ID suffix changes as a to-be-paired second electronic device, and obtains a corresponding second sound intensity. The change of the Bluetooth ID suffix includes, for example, a newly-added suffix of the changed Bluetooth ID compared with an original Bluetooth ID. For example, the original Bluetooth ID does not have a suffix, and a suffix is added to the changed Bluetooth ID compared with the original Bluetooth ID; or the original Bluetooth ID has a suffix, and another suffix is added to the changed Bluetooth ID compared with the original Bluetooth ID. A large-screen device determines a corresponding device identity based on a part of the Bluetooth ID that does not change (that is, determines that the device and a device corresponding to the Bluetooth ID that has a newly-added suffix part are a same device), and determines that the second sound intensity is a newly-added suffix part of the Bluetooth ID.
For example, it is assumed that an original Bluetooth ID (that is, a Bluetooth ID before the sound box A determines the second sound intensity) of the sound box A is XXX, and an original Bluetooth ID (that is, a Bluetooth ID before the sound box B determines the second sound intensity) of the sound box B is XXXX. In the Bluetooth scanning process, the first electronic device determines that a suffix is added to the Bluetooth ID of the sound box A, where the Bluetooth ID of the sound box A changes from XXX to XXX-120, and a suffix 120 is added, and therefore determines that the sound intensity collected by the sound box A is 120 dB; and determines that a suffix is added to the Bluetooth ID of the sound box B, where the Bluetooth ID of the sound box B changes from XXXX to XXXX-60, and a suffix 60 is added, and therefore determines that the sound intensity collected by the sound box B is 60 dB.
In this way, the first electronic device may determine the second sound intensity by simply comparing a change between a first Bluetooth ID and a second Bluetooth ID, thereby simplifying a process of determining the sound intensity.
According to the first aspect or any one of the foregoing implementations of the first aspect, the receiving at least one second sound intensity sent by one or more second electronic devices includes: obtaining second Bluetooth names of the one or more second electronic devices, where the second Bluetooth names include at least one piece of second sound intensity information, and the at least one piece of second sound intensity information indicates the at least one second sound intensity; and determining the at least one second sound intensity based on the second Bluetooth names.
In some embodiments, the second electronic device edits the Bluetooth ID based on a preset rule, and adds second sound intensity information to the Bluetooth ID. In this case, in a process of scanning a to-be-paired device, the first electronic device can determine an edited Bluetooth ID that meets the preset rule. Then, the first electronic device parses the edited Bluetooth ID based on the preset rule, and can obtain the second sound intensity (for example, obtain the second sound intensity from a preset field).
According to the first aspect or any one of the foregoing implementations of the first aspect, the first sound is generated by a second operation of the user, and the second operation includes one or more of the following content: an operation of tapping the target device by using the knuckle of the user, and an operation of making a sound by the user at or near the target device; or the first sound is generated by the target device by playing audio.
According to the first aspect or any one of the foregoing implementations of the first aspect, in a case in which the first sound is generated by the second operation of the user, the method further includes: prompting the user to perform the second operation.
In some embodiments, after detecting the sound channel configuration operation of the user, the first electronic device may further display operation guide information to guide the user to separately tap each to-be-paired second electronic device. The operation guide information may include a text, a picture, an animation, and/or a video.
In this way, the user can easily understand a sound channel configuration process, and avoid a sound channel configuration failure caused by an operation error.
According to the first aspect or any one of the foregoing implementations of the first aspect, the method further includes: prompting the user that the sound channel configuration is completed.
In some implementations, after determining that the sound channel configuration is completed, the first electronic device may further display prompt information or play a voice prompt, to prompt the user that the sound channel configuration is completed for use. Alternatively, each time a sound channel is configured, the first electronic device displays prompt information once or plays a voice prompt, to present the sound channel configuration process to the user.
In this way, the user can determine, based on the prompt, that the sound channel configuration is completed, and may start to play a sound, thereby improving user interaction and improving user experience.
In some embodiments, after completing sound channel configuration, the first electronic device may invoke an audio management module to identify a sound channel that is configured, where an identifier indicates a correspondence between the sound channel and the second electronic device. Then, in a sound playing process, the audio management module may send, based on the identifier, source audio of different channels to a corresponding second electronic device for playing. An audio file to be played by the first electronic device should include multi-channel audio, where each piece of source audio corresponds to one sound channel, and the first electronic device plays corresponding source audio by using different sound channels, so that a stereo sound effect can be implemented.
According to a second aspect, a sound channel configuration method is provided, and is applied to a second electronic device. The method includes: determining a second sound intensity of a first sound based on a sound collected by a second sound collection apparatus of the second electronic device; sending the second sound intensity to a first electronic device; and receiving an audio file sent by the first electronic device, where the audio file is sent by the first electronic device after the first electronic device determines, based on a first sound intensity and the second sound intensity, a target sound channel that matches the second electronic device, the audio file corresponds to the target sound channel, the first sound intensity is a sound intensity that is of the first sound and that is determined by the first electronic device, and the target sound channel is a sound channel in to-be-configured sound channels of the first electronic device; and playing audio based on the audio file.
In some embodiments, if the second electronic device does not establish a pairing connection to another electronic device, the second electronic device is in an unpaired state. When the second electronic device is in the unpaired state, if it is determined that a sound feature of a collected sound meets a preset condition, that the collected sound is a sound used for pairing is determined. In this case, the second electronic device determines a second sound intensity of the sound, and edits, by using the second sound intensity, a Bluetooth ID used for pairing.
According to the second aspect, the determining a second sound intensity of a first sound based on a sound collected by a second sound collection apparatus of the second electronic device includes: if a sound feature of the sound collected by the second sound collection apparatus of the second electronic device meets a preset condition, determining that the collected sound is the first sound, and determining the second sound intensity of the first sound, where the sound feature includes one or more of a frequency feature, an amplitude feature, a waveform feature, and a duration feature.
In this way, the second electronic device determines the first sound by using the sound feature, and then sends a sound intensity of the first sound to the first electronic device, so that the first electronic device performs sound channel configuration by using the first sound, to avoid interference caused to a sound channel configuration process when another sound is collected.

In some scenarios, to implement a stereo sound effect, an electronic device (for example, a large-screen device) needs to establish connections to at least two wireless sound boxes. In a sound playing process, the at least two wireless sound boxes can form a sound box system to work in coordination. In the sound box system, one wireless sound box corresponds to one sound channel, and respective audio playing effects are created at different positions, so that the sound box system formed by the wireless sound boxes can provide good auditory experience for a user.
For example, as shown in
It can be learned that the sound box system provides a more stereo sound playing effect for the user on a premise that the wireless sound boxes in the sound box system separately establish correspondences with different sound channels of the electronic device, and the different sound channels are configured for corresponding wireless sound boxes to output sounds corresponding to the sound channels.
In some embodiments, after detecting a sound channel configuration operation of the user, the electronic device starts to perform Bluetooth scanning, and obtains and displays a Bluetooth identity document (identity document, ID) list that is obtained through scanning. The user configures a sound channel for a sound box at a corresponding position based on the Bluetooth ID. After detecting a selection confirmation operation performed by the user on the Bluetooth ID, the electronic device establishes a Bluetooth connection to the sound box and establishes a correspondence between the sound box and a corresponding sound channel. However, during initial sound box pairing, the sound box Bluetooth ID is usually a default name, and the user may not immediately establish a correspondence between the Bluetooth ID and a corresponding sound box. For example, in the scenario shown in
In some other embodiments, after detecting an operation of pressing a physical button on the sound box by the user, the sound box sends a signal to the electronic device, and the electronic device highlights the Bluetooth ID of the sound box in a displayed Bluetooth ID list, so that the user can confirm the Bluetooth ID of the sound box. Then, after establishing a pairing relationship with the sound box in response to an operation of tapping the highlighted Bluetooth ID by the user, the electronic device further needs to detect a sound channel configuration operation of the user, and perform sound channel configuration on the sound box. However, it can be learned that this sound channel configuration method still depends on manual confirmation of the user, and the user performs a plurality of sound channel configuration operations on the display, which makes it difficult for the user to perform operations and reduces user experience.
Based on this, embodiments of this application provide a sound channel configuration method. After a sound channel configuration operation of a user is detected, an electronic device can automatically configure a corresponding sound channel for each sound box based on a sound intensity collected by the electronic device and a sound intensity collected by each sound box whose sound channel is to be configured, thereby reducing operation difficulty of the user and improving user experience.

The internal memory 121 may include a program storage area and a data storage area. The program storage area may store an operating system, an application required by at least one function (for example, a voice playing function or an image playing function), and the like. The data storage area may store data (for example, audio data and an address book) and the like created in a process of using the first electronic device 100. In addition, the internal memory 121 may include a high-speed random access memory, or may include a nonvolatile memory, for example, at least one magnetic disk storage device, a flash memory, or a universal flash storage (universal flash storage, UFS). The processor 110 runs instructions stored in the internal memory 121 and/or instructions stored in a memory disposed in the processor, to perform various function applications of the first electronic device 100 and data processing.
The audio module 170 is configured to convert digital audio information into an analog audio signal for output, and is also configured to convert analog audio input into a digital audio signal. The audio module 170 may be further configured to code and decode an audio signal. In some embodiments, the audio module 170 may be disposed in the processor 110, or some functional modules in the audio module 170 are disposed in the processor 110. The first electronic device 100 may implement an audio function such as music playing and recording by using the audio module 170, the application processor, and the like. The audio module 170 may include, for example, a speaker, a receiver, and a microphone.
The microphone, also referred to as a “mic” or a “sound conducting device”, is configured to convert a sound signal into an analog audio electrical signal. The first electronic device 100 may collect a surrounding sound signal by using the microphone. The microphone may be a built-in component of the first electronic device 100, or may be an external accessory of the first electronic device 100.
In some embodiments, the first electronic device 100 may include one or more microphones. Each microphone or a plurality of microphones cooperate to implement a function of collecting sound signals in all directions, and converting the collected sound signals into analog audio electrical signals, and may further implement a noise reduction function, a sound source identification function, a directional recording function, and the like.
For example,
It should be noted that, for “up”, “down”, “left”, and “right” described in subsequent embodiments, refer to the orientation shown in
In some embodiments, the first electronic device 100 can determine a position relationship between the electronic device and another device based on sound signals of the another device that are collected by the plurality of microphones of the first electronic device 100. For example, the another device is a sound box. The plurality of microphones of the first electronic device 100 are separately installed at different positions in the first electronic device 100. Therefore, distances between the microphones and the sound box are different. The first electronic device 100 can collect, by using each microphone, the sound signal sent by the sound box. A shorter distance between the microphone and the sound box indicates a larger collected sound intensity. Therefore, the first electronic device 100 may determine a position relationship between the sound box and the first electronic device 100 by using the sound intensity, to perform sound channel configuration. For example, it is assumed that a sound box A emits a sound signal, and to-be-configured sound channels of the first electronic device 100 include a left sound channel and a right sound channel. As shown in
In some embodiments, the first electronic device 100 may further include more microphones. The microphone may be a directional microphone, and may collect a sound signal in a specific direction. Alternatively, the microphone may be a non-directional microphone, to collect sound signals in all directions, or may collect a sound signal within a specific range based on a position of the microphone in the first electronic device 100.
A quantity of microphones is not specifically limited in embodiments of this application.
The sensor module 180 may include a pressure sensor, a distance sensor, an optical proximity sensor, a fingerprint sensor, a temperature sensor, a touch sensor, an ambient light sensor, and the like.
The pressure sensor is configured to sense a pressure signal, and can convert the pressure signal into an electrical signal. In some embodiments, the pressure sensor may be disposed on the display 193. There are many types of pressure sensors like a resistive pressure sensor, an inductive pressure sensor, and a capacitive pressure sensor. The capacitive pressure sensor may include at least two parallel plates made of conductive materials. When a force is applied to the pressure sensor, capacitance between electrodes changes. The first electronic device 100 determines an intensity of pressure based on the change in the capacitance. When a touch operation is performed on the display 193, the first electronic device 100 detects an intensity of the touch operation by using the pressure sensor. The first electronic device 100 may also calculate a touch position based on a detection signal of the pressure sensor.
The touch sensor is also referred to as a “touch component”. The touch sensor may be disposed on the display 193, and the touch sensor and the display 193 form a touchscreen, which is also referred to as a “touch screen”. The touch sensor is configured to detect a touch operation performed on or near the touch sensor. The touch sensor may transfer the detected touch operation to the application processor to determine a type of the touch event. Visual output related to the touch operation may be provided by using the display 193. In some other embodiments, the touch sensor may also be disposed on a surface of the first electronic device 100 at a position different from that of the display 193.
In some embodiments, the first electronic device 100 displays a sound box pairing confirmation interface by using the display 193, and after detecting, by using the touch sensor, that a user taps to start a pairing operation or receiving, by using the wireless communication module 160, a control instruction of a remote control, automatically establishes a correspondence between the sound box and a corresponding sound channel, to complete sound channel configuration.
The button 190 includes a power button, a volume button, and the like. The button 190 may be a mechanical button, or may be a touch button. The first electronic device 100 may receive button input, and generate button signal input related to a user setting and function control of the first electronic device 100.
The indicator 191 may be an indicator, and may be configured to indicate a power status, or may be configured to indicate a message, a notification, or the like.
For ease of description, the following embodiments are described by using an example in which the first electronic device 100 is a large-screen device and the second electronic device 200 is a wireless sound box. A person skilled in the art should understand that, unless otherwise specified, various forms or combinations of various forms of another electronic device, a single second electronic device, a plurality of second electronic devices, or the like also fall within the scope of embodiments of this application.
In some embodiments, when sound channel configuration is performed for the large-screen device, a correspondence between the wireless sound box at a corresponding position and a corresponding sound channel needs to be established. For example, in a scenario shown in
For example, a user may make a sound at or near a position of the wireless sound box 200, and the large-screen device detects the sound, and determines, based on a sound intensity of the sound, a to-be-configured sound channel corresponding to the wireless sound box at a position of the sound. As shown in
As shown in
Correspondingly, the user may further tap the sound box B by using the knuckle, and the large-screen device 100 and the wireless sound box 200 repeat the foregoing steps, so that the large-screen device 100 can automatically complete right sound channel configuration based on a sound intensity of the tapping sound received by the microphone of the large-screen device 100 and a sound intensity that is of the tapping sound received by the wireless sound box 200 and that is sent by the wireless sound box 200 and received by the large-screen device 100.
In this way, the user can complete sound channel configuration on the large-screen device by using only a simple tapping operation. Operation steps are simple, sound channel configuration efficiency is high, and user experience can be effectively improved.
It should be noted that sound intensities of the sound emitted by the user at or near the position of the wireless sound box each time should be uniform and close. For example, the sound is a tapping sound generated after the user taps the wireless sound box, and the user should tap each wireless sound box with a same or similar force each time, so that sound intensities of all tapping sounds are similar, to avoid a sound channel configuration error caused by a large difference between the sound intensities of the tapping sounds. In addition, the wireless sound boxes should have the same or similar sound receiving performance, to avoid a sound channel configuration error caused by a large difference in the sound receiving performance of the wireless sound boxes. Details are not described again in the following.
The following describes in detail the sound channel configuration method provided in embodiments of this application.
For example,
S501: A large-screen device detects a sound channel configuration operation of a user, and determines to start sound channel configuration.
The sound channel configuration operation includes, for example, a touch operation (for example, an operation of tapping a control for confirming to start the sound channel configuration) of the user on a display, a voice operation indicating the sound channel configuration, an operation of inputting a sound channel configuration command by using a physical button on the large-screen device, and an operation of inputting a sound channel configuration command by using a remote control.
In some embodiments, after detecting the sound channel configuration operation, the large-screen device determines that sound channel configuration needs to be performed and that pairing with a wireless sound box is required, and establishes a pairing relationship like a Bluetooth pairing relationship or a Wi-Fi pairing relationship. Then, the large-screen device can configure, based on the paring relationship, a sound channel of the large-screen device for a corresponding wireless sound box, so that sound playing of the large-screen device can be subsequently implemented by using the configured wireless sound box. In this case, after detecting the sound channel configuration operation, the large-screen device starts to scan to-be-paired devices, and then establishes correspondences between a sound channel and some or all devices in the to-be-paired devices by performing the following steps, to complete sound channel configuration.
For example, in an interface 601 shown in (a) in
In some embodiments, after detecting the sound channel configuration operation of the user, the large-screen device further needs to determine a quantity of to-be-configured sound channels, to subsequently determine data of a to-be-paired wireless sound box that needs to be detected, to perform pairing. For example, if the large-screen device determines that the to-be-configured sound channels include a left sound channel and a right sound channel, the large-screen device needs to detect only two wireless sound boxes to perform pairing. For another example, if the large-screen device determines that the large-screen device is a 5.1-channel device, the large-screen device needs to complete pairing with six wireless sound boxes to complete sound channel configuration.
S502: The large-screen device obtains a Bluetooth TD of the wireless sound box.
In some embodiments, after enabling a Bluetooth function, the large-screen device can scan for a nearby device that has enabled Bluetooth and is in a to-be-paired state, and obtain a Bluetooth ID of the device. For example, in a Bluetooth scanning process, the large-screen device can obtain a Bluetooth ID list that includes the Bluetooth ID of the wireless sound box.
It should be noted that a sequence of performing step S501 and step S502 is not limited in this embodiment of this application. For example, when the Bluetooth function is enabled on the large-screen device, the large-screen device may start to scan a Bluetooth device when no sound channel configuration operation of the user is detected; or the large-screen device starts to scan a Bluetooth device after determining that the sound channel configuration operation of the user is detected.
S503: The large-screen device collects a sound and determines a first sound intensity of the sound.
In some embodiments, the first sound intensity includes, for example, a sound intensity of a sound that corresponds to a position of the wireless sound box and that is collected by the large-screen device by using a microphone of the large-screen device. For example, after determining that the sound channel configuration needs to be started, the large-screen device performs sound pickup by using the microphone of the large-screen device, and determines a first sound intensity of the picked-up sound. There are one or more first sound intensities, corresponding to a quantity of microphones configured for the large-screen device. For example, if the large-screen device includes two microphones, the two microphones separately collect sound intensities of the sound corresponding to the position of the wireless sound box, and the large-screen device obtains two first sound intensities.
In some embodiments, when determining that a sound feature of the collected sound meets a preset condition, the large-screen device determines that the collected sound is a sound used to configure a sound channel, and then determines the first sound intensity of the sound. The sound feature includes one or more of a frequency feature, an amplitude feature, a waveform feature, and a duration feature.
For example, a sound frequency of tapping a sound box by a human knuckle is generally 800 Hz to 1200 Hz. In a sound pickup process, the large-screen device picks up a sound in the frequency range, and obtains a corresponding sound intensity. Further, optionally, the large-screen device may determine whether a feature of the picked-up sound in the frequency range matches a feature (for example, a sound waveform has one or more peaks) of a sound emitted by tapping a sound box by using the human knuckle. If the two features match, the large-screen device determines that the picked-up sound in the frequency range is the sound emitted by tapping the sound box by using the human knuckle, and determines that the sound is indeed a sound generated when the user wants to perform sound channel configuration on the large-screen device and taps the sound box by using the knuckle, and is not an interference sound like a human sound, music, or environmental background noise.
In the scenario shown in
In some embodiments, a sound corresponding to the position of the wireless sound box may further include a sound generated at or near the position of the wireless sound box, for example, a sound generated when the user beats the wireless sound box, a sound generated when the user makes a finger, claps, or coughs near the wireless sound box, and audio played by the wireless sound box. A position near the wireless sound box indicates that a sound generating position is near the position of the wireless sound box, for example, a distance between the sound generating position and the position of the wireless sound box is less than or equal to a preset threshold. For example, in the scenario shown in
In some embodiments, an electronic device collects a sound within preset time after the sound channel configuration operation of the user is detected, and determines a first sound intensity of the sound. If no sound is collected within the preset time, the sound channel configuration is stopped. For example, the preset time is 5 minutes, and the electronic device detects a sound whose sound frequency ranges from 800 Hz to 1200 Hz within 5 minutes after the sound channel configuration operation of the user is detected. If the sound in the sound frequency range is detected within 5 minutes, the first sound intensity is determined; and if no sound in the sound frequency range is detected within 5 minutes, the sound channel configuration is stopped.
S504: The wireless sound box collects the sound, determines a second sound intensity of the sound, and edits the Bluetooth ID by using the second sound intensity.
In some embodiments, if the wireless sound box does not establish the pairing connection to another electronic device, the wireless sound box is in an unpaired state. When the wireless sound box is in the unpaired state, if it is determined that a sound feature of a collected sound meets the preset condition, that the collected sound is a sound used for pairing is determined. In this case, the wireless sound box determines the second sound intensity of the sound, and edits, by using the second sound intensity, a Bluetooth ID used for pairing. The sound feature includes one or more of the frequency feature, the amplitude feature, the waveform feature, and the duration feature.
In some embodiments, the second sound intensity includes, for example, a sound intensity of a sound that corresponds to a position of the wireless sound box and that is collected by the wireless sound box by using a microphone of the wireless sound box. There are one or more second sound intensities, corresponding to a quantity of to-be-paired wireless sound boxes. For example, the quantity of the to-be-paired wireless sound boxes is 2, and the two wireless sound boxes respectively collect sound intensities of sounds corresponding to respective locations. In this case, a quantity of the second sound intensities is 2.
For example, in the scenario shown in
It should be understood that, in addition to using the sound intensity as a suffix of the Bluetooth ID to edit the Bluetooth ID, the wireless sound box may also use the sound intensity as a prefix of the Bluetooth ID, a character inserted in the middle of the Bluetooth ID, and the like to edit the Bluetooth ID. Alternatively, the wireless sound box may not edit the Bluetooth ID, but edit another field in the Bluetooth protocol.
S505: The wireless sound box sends an edited Bluetooth ID to the large-screen device.
In some embodiments, after the wireless sound box edits the Bluetooth ID based on the second sound intensity, in a process of scanning for the nearby device that has enabled Bluetooth and is in the to-be-paired state, the large-screen device can obtain a Bluetooth ID edited by the wireless sound box. In other words, the wireless sound box sends the edited Bluetooth ID to the large-screen device.
S506: The large-screen device determines the second sound intensity based on the Bluetooth ID.
In some embodiments, in the Bluetooth scanning process, if the large-screen device finds that some or all Bluetooth ID suffixes in the Bluetooth ID list obtained through scanning change, the large-screen determines the Bluetooth device whose Bluetooth ID suffix changes as a to-be-paired wireless sound box, and obtains a corresponding second sound intensity. The change of the Bluetooth ID suffix includes, for example, a newly-added suffix of the changed Bluetooth ID compared with an original Bluetooth ID. For example, the original Bluetooth ID does not have a suffix, and a suffix is added to the changed Bluetooth ID compared with the original Bluetooth ID; or the original Bluetooth ID has a suffix, and another suffix is added to the changed Bluetooth ID compared with the original Bluetooth ID. The large-screen device determines a corresponding device identity based on a part of the Bluetooth ID that does not change (that is, determines that the device and a device corresponding to the Bluetooth ID that has a newly-added suffix part are a same device), and determines that the second sound intensity is a newly-added suffix part of the Bluetooth ID.
For example, as shown in Table 1, it is assumed that, in the scenario shown in
In some embodiments, the electronic device receives the second sound intensity within the preset time after collecting the sound, that is, performs step S505 and step S506 within the preset time after step S503 is performed. If no second sound intensity is received within the preset time, the sound channel configuration is stopped. For example, the preset time is 10 minutes, and the electronic device detects, within 10 minutes after collecting the sound, a device whose Bluetooth ID changes, and determines the second sound intensity. If the device whose Bluetooth ID changes is detected within 10 minutes, the second sound intensity is determined; or if no device whose Bluetooth ID changes is detected within 10 minutes, the sound channel configuration is stopped.
In some implementations, if in step S504, what is edited by the wireless sound box is not the Bluetooth ID, but the another field in the Bluetooth protocol, step S505 is that the wireless sound box sends an edited Bluetooth protocol field to the large-screen device, and step S506 is that the large-screen device determines the second sound intensity based on the Bluetooth protocol field.
In some implementations, in step S504, the wireless sound box edits the Bluetooth ID based on a preset rule, and adds second sound intensity information to the Bluetooth ID. In this case, in step S506, in a process of scanning a to-be-paired device, the large-screen device can determine an edited Bluetooth ID that meets the preset rule. Then, the large-screen device parses the edited Bluetooth ID based on the preset rule, and can obtain the second sound intensity (for example, obtain the second sound intensity from a preset field). In other words, the large-screen device does not need to determine a changed Bluetooth ID based on the Bluetooth ID list previously obtained through scanning, and then determine the second sound intensity based on a changed part.
In some scenarios, after determining the sound intensity, the wireless sound box may further directly send the sound intensity to the large-screen device. For example, if the wireless sound box and the large-screen device are connected to a same wireless network, the wireless sound box can directly send the sound intensity to the large-screen device through a Wi-Fi connection. Based on this, the large-screen device and the wireless sound box may not need to perform step S502 and step S505, and in step S504, the wireless sound box does not need to edit the Bluetooth ID.
It should be noted that an execution sequence of step S503 and step S504 to step S506 is not limited in this embodiment of this application. For example, the large-screen device first collects the sound, determines the first sound intensity of the sound, then receives the Bluetooth ID sent by the wireless sound box, and determines the second sound intensity (that is, first performs step S503, and then performs step S504 to step S506). For another example, the large-screen device first receives the Bluetooth ID sent by the wireless sound box, determines the second sound intensity, then collects the sound, and determines the first sound intensity of the sound (that is, first performs step S504 to step S506, and then performs step S503). For another example, when collecting the sound and determining the first sound intensity of the sound at the same time, the large-screen device receives the Bluetooth ID sent by the wireless sound box and determines the second sound intensity (that is, performs step S503 in parallel with step S504 to step S506).
S507: The large-screen device determines a correspondence between the wireless sound box and the sound channel based on the first sound intensity and the second sound intensity.
In some implementations, after obtaining the first sound intensity, the large-screen device can roughly determine the to-be-configured sound channel based on the first sound intensity.
For example, in the scenario shown in
In some implementations, after roughly determining the to-be-configured sound channel, the large-screen device can determine, based on the second sound intensity, which wireless sound box is specifically the wireless sound box at the sound-emitting position, to establish a correspondence between the wireless sound box at the sound-emitting position and the to-be-configured sound channel.
For example, in the scenario shown in
S508: The wireless sound box performs pairing with the large-screen device and performs sound channel configuration.
In some embodiments, after determining the correspondence between the wireless sound box and the sound channel, the large-screen device sends a pairing request to a corresponding wireless sound box. Correspondingly, the wireless sound box sends a pairing response, and the large-screen device completes pairing with the wireless sound box based on the pairing response, establishes a pairing relationship like a Bluetooth pairing relationship and a Wi-Fi pairing relationship, and configures a determined to-be-configured sound channel for the wireless sound box. The configuring the to-be-configured sound channel for the wireless sound box indicates that a correspondence between the to-be-configured sound channel and the wireless sound box is established, and subsequently, a sound of the corresponding sound channel is played by using the wireless sound box. Optionally, the configuring the to-be-configured sound channel for the wireless sound box may also be described as providing the wireless sound box with the to-be-configured sound channel.
For example, in the scenario shown in
Correspond to the scenario shown in
In some other embodiments, the step of establishing the pairing relationship between the large-screen device and the wireless sound box and the step of performing sound channel configuration on the wireless sound box by the large-screen device may be performed in a same step, or may be separately performed in different steps. For example, as described in step S508, after determining the to-be-configured sound channel and the corresponding to-be-paired wireless sound box, the large-screen device may pair with the wireless sound box and complete configuration on the to-be-configured sound channel. In other words, the step of establishing the pairing relationship and the step of configuring the sound channel are synchronously performed. For another example, after determining the second sound intensity in step S506, the large-screen device may determine a wireless sound box corresponding to a largest second sound intensity. Then, the large-screen device can directly establish the pairing relationship with the wireless sound box. In this case, in step S508, based on the established pairing relationship, the large-screen device needs to only complete sound channel configuration, and does not need to perform pairing. In other words, the step of establishing the pairing relationship and the step of configuring the sound channel are performed separately.
In some embodiments, after completing sound channel configuration, the large-screen device may invoke an audio management module to identify a sound channel that is configured, where an identifier indicates a correspondence between the sound channel and the wireless sound box. Then, in a sound playing process, the audio management module may send, based on the identifier, source audio of different channels to a corresponding wireless sound box for playing. For example, in the scenario shown in
It should be noted that, in the steps shown in
In this way, based on the sound channel configuration method provided in this embodiment of this application, the large-screen device can automatically complete sound channel configuration in response to the sound channel configuration operation of the user. In a sound channel configuration process, the user needs to only complete a simple operation such as tapping the wireless sound box, does not need to confirm a name of the wireless sound box, and does not need to perform more operations on the display of the large-screen device. In this way, user operations in the sound channel configuration process are effectively simplified, and user experience is improved.
In some implementations, after determining that the sound channel configuration is completed, the large-screen device may further display prompt information or play a voice prompt, to prompt the user that the sound channel configuration is completed for use. Alternatively, each time a sound channel is configured, the large-screen device displays prompt information once or plays a voice prompt, to present the sound channel configuration process to the user.
In some embodiments, after detecting the sound channel configuration operation of the user, the large-screen device may further display operation guide information to guide the user to separately tap each to-be-paired wireless sound box. The operation guide information may include a text, a picture, an animation, and/or a video.
In some scenarios, if the large-screen device determines that there is one to-be-configured sound channel, step S503 may not be performed, that is, the first sound intensity does not need to be collected. Then, based on an obtained second sound intensity, the large-screen device directly pairs with the wireless sound box that collects a largest second sound intensity, and configures the sound channel for the wireless sound box. In other words, after determining the Bluetooth device whose Bluetooth ID suffix changes, the large-screen device establishes a correspondence between the Bluetooth device and the to-be-configured sound channel, to complete sound channel configuration.
In some other scenarios, in a sound box system, for example, in a dual-channel sound box system (that is, a stereo sound box system including the left sound channel and the right sound channel), in which there is only one wireless sound box in each direction corresponding to two sides of the central axis of the large-screen device, the large-screen device can directly determine the to-be-configured sound channel based on the first sound intensity collected by the microphone of the large-screen device at one time. In this case, the to-be-configured sound channel may be directly determined after the first sound intensity is determined in step S503, without waiting for receiving the second sound intensity to determine the to-be-configured sound channel. For example, in the dual-channel sound box system, after collecting the tapping sound, the large-screen device may determine, based on the first sound intensity of the tapping sound, that the to-be-configured sound channel is the left sound channel or the right sound channel. Optionally, a current scenario also includes a scenario in which one wireless sound box is configured in a central axis direction of the large-screen device.
For example,
S801: A large-screen device detects a sound channel configuration operation of a user, and determines to start sound channel configuration.
S802: The large-screen device obtains a Bluetooth ID of a wireless sound box.
Optionally, for step S801 and step S802, refer to related descriptions of step S501 and step S502. Details are not described herein again.
S803: The large-screen device collects a sound and determines, based on a first sound intensity of the sound, a to-be-configured sound channel.
For example, it is assumed that the large-screen device includes a left sound channel and a right sound channel. In the scenario shown in
Optionally, for remaining content of step S803, refer to related descriptions of step S503. Details are not described herein again.
S804: The wireless sound box collects the sound, determines a second sound intensity of the sound, and edits a Bluetooth ID by using the second sound intensity.
S805: The wireless sound box sends an edited Bluetooth ID to the large-screen device.
Optionally, for step S804 and step S805, refer to related descriptions of step S504 and step S505. Details are not described herein again.
S806: The large-screen device determines, based on a Bluetooth ID suffix, a wireless sound box whose second sound intensity is largest, and determines a correspondence between the wireless sound box and the to-be-configured sound channel.
For example, in the scenario shown in
Optionally, for remaining content of step S806, refer to related descriptions of step S506 and step S507. Details are not described herein again.
S807: The wireless sound box performs pairing with the large-screen device and performs sound channel configuration.
Optionally, for step S807, refer to related descriptions of step S508. Details are not described herein again.
Then, step S802 to step S807 are cyclically performed to complete configuration on all sound channels of the large-screen device.
In this way, in the method shown in
Further, optionally, the large-screen device may further display prompt information indicating that wireless sound box pairing is completed, thereby increasing interest of a sound channel configuration process in which the user participates, and further improving user experience.
In some other scenarios, compared with the foregoing dual-channel sound box system in which there is only one wireless sound box in each direction of corresponding directions on two sides of the central axis of the large-screen device, in a sound box system in which there are two or more wireless sound boxes in each direction of corresponding directions on two sides of the central axis of the large-screen device, because the microphones of the large-screen device are generally located at corresponding positions on the two sides of the central axis of the large-screen device or located at corresponding positions on the central axis, the large-screen device cannot directly determine the to-be-configured sound channel based on the first sound intensities collected by the microphones at one time, and needs to wait until collection of some or all of the first sound intensities is completed, so that the to-be-configured sound channel can be determined. The some of the first sound intensities include all first sound intensities corresponding to a one-side direction of the central axis of the large-screen device.
For example, the large-screen device is a four-channel surround device, that is, the large-screen device may output four-channel audio, and needs to establish the pairing relationship with four wireless sound boxes. However, the large-screen device is configured with only two microphones, and the large-screen device cannot distinguish between a left front sound channel and a left rear sound channel or distinguish between the right front sound channel and the right rear sound channel based on first sound intensities collected by the two microphones at one time. Therefore, the large-screen device can further confirm the to-be-configured sound channels only after obtaining all first sound intensities corresponding to the left side of the large-screen device, or all first sound intensities corresponding to the right side of the large-screen device, or all first sound intensities.
For example, as shown in
It is assumed that after a user taps the wireless sound box 200 by using a knuckle, the first sound intensity and the second sound intensity that are determined by the large-screen device 100 are shown in Table 2 below. It is assumed that the user first taps the sound box Ain the scenario shown in
In other words, the method shown in
The following uses the four-channel surround sound box system shown in
Scenario 1: The user sequentially taps the wireless sound box located in one direction of the central axis of the large-screen device, and then sequentially taps the wireless sound box located in the other direction of the central axis of the large-screen device.
In some embodiments, the large-screen device can determine the to-be-configured sound channel only after obtaining first sound intensities corresponding to all the wireless sound boxes located in the one-side direction of the central axis of the large-screen device. Then, the large-screen device may first complete sound channel configuration on the determined to-be-configured sound channel based on the first sound intensities and the corresponding second sound intensities, and then continue to perform sound channel configuration on another sound channel.
For example, an example in which in the four-channel surround sound box system (that is, two wireless sound boxes are configured in the one-side direction of the central axis of the large-screen device) shown in
In other words, each time after detecting a tapping sound, the large-screen device 100 can determine a corresponding candidate target device (that is, the to-be-paired device) based on the second sound intensity. Therefore, a quantity of the to-be-paired devices is equal to a quantity of the tapping sounds made by the user by tapping the wireless sound box (as shown in
Then, as shown in Table 2, the first sound intensity corresponding to the sound box A tapped by the user by using the knuckle is vertically compared with the first sound intensity corresponding to the sound box D tapped by the user by using the knuckle, that is, the first sound intensity 100 dB that corresponds to the sound box A and that is collected by the microphone 31 is greater than the first sound intensity 90 dB that corresponds to the sound box D, and the first sound intensity 90 dB that corresponds to the sound box A and that is collected by the microphone 32 is greater than the first sound intensity 70 dB that corresponds to the sound box D. Therefore, it is determined that the sound box A is located at a position that is on the left side of the large-screen device 100 and that is close to the large-screen device 100 and a corresponding to-be-configured sound channel is the left front sound channel; and that a sound box D is located at a position that is on the left side of the large-screen device 100 and that is far away from the large-screen device 100, and a corresponding to-be-configured sound channel is the left rear sound channel. In this case, the left front sound channel may be configured for the sound box A, and the left rear sound channel may be configured for the sound box D, to complete sound channel configuration corresponding to the left side of the large-screen device.
Similarly, as shown in
It should be noted that, in a general situation, as shown in
It should be noted that, in this embodiment of this application, a tapping sequence in which the user sequentially taps the wireless sound boxes located in the one-side direction of the central axis of the large-screen device is not specifically limited. For example, in the sound channel configuration scenario of the four-channel surround sound box system shown in
Scenario 2: The user cross-taps the wireless sound boxes located on two sides of the central axis of the large-screen device.
In some embodiments, in this embodiment of this application, a sequence of tapping the wireless sound box 200 by the user is not limited. In this case, the user may start tapping the wireless sound box on the other side before tapping all wireless sound boxes in one-side direction of the central axis of the large-screen device is completed. Therefore, the large-screen device first determines a side, on the central axis of the large-screen device, on which the first sound intensities are all determined, and then preferentially performs sound channel configuration on the side.
For example, an example in which in the four-channel surround sound box system (that is, two wireless sound boxes are configured in the one-side direction of the central axis of the large-screen device) shown in
In some embodiments, in the foregoing scenario 1 and scenario 2, each time after determining the first sound intensity, the large-screen device needs to perform the step of determining the to-be-configured sound channel. However, in the scenario in which there are two or more wireless sound boxes in each direction of corresponding directions on the two sides of the central axis of the large-screen device, the large-screen device can determine the to-be-configured sound channel only after obtaining the first sound intensities at least twice. Therefore, in the foregoing scenario 1 and scenario 2, the large-screen device may first determine the quantity of the wireless sound boxes in each direction of the corresponding directions on the two sides of the central axis of the large-screen device, determine a minimum quantity of the wireless sound boxes in a direction on one side, and determine the minimum quantity as a preset threshold. Then, in the sound channel configuration process, after obtaining a quantity that is of the first sound intensity and that is equal to the preset threshold, the large-screen device starts to determine the to-be-configured sound channel, thereby reducing calculation power consumption of the large-screen device. For example, in the four-channel surround sound box system scenario shown in
In some other embodiments, the large-screen device may further uniformly perform the step of determining the to-be-configured sound channel after obtaining all first sound intensities. For example, in the four-channel surround sound box system scenario shown in
In this way, after obtaining all the first sound intensities, the large-screen device determines the to-be-configured sound channel in a centralized manner, and performs sound channel configuration, so that accuracy of sound channel configuration can be improved.
It should be noted that, the foregoing correspondence between a moment for determining the to-be-configured sound channel and the sequence of tapping the wireless sound box by the user in the scenario in which there are two or more wireless sound boxes in each direction of the corresponding directions on the two sides of the central axis of the large-screen device is described merely as an example. If more than two microphones are configured in the large-screen device, or a microphone configuration position is different from the position shown in
In some other scenarios, it is assumed that the large-screen device is configured with two microphones (for example, the microphone 31 and the microphone 32) shown in
In this way, the sound channel configuration method provided in embodiments of this application can be applied to large-screen devices including different sound channel types, and sound channel configuration on the large-screen devices can be adaptively completed, thereby improving user experience.
