The present disclosure relates generally to an electronic device and a method of controlling the electronic device using audio components (i.e., transducers) of the electronic device.
With the development of electronic technology, electronic devices have been developed to provide users with various types of multimedia-related services, such as music, video, digital broadcast, etc., as well as voice and video call services. In order to provide such services, electronic devices may be configured to include various transducers, e.g., a speaker, a receiver, earphones, a microphone, etc.
The transducers are disposed adjacent to an opening formed in one side of the housing of electronic devices so that they can efficiently receive/output audio signals from/to the outside.
As such, existing transducers are only used for the input or output of audio signals; however, they have not been used to control electronic devices.
The present disclosure has been made to address the above-mentioned problems and disadvantages, and to provide at least the advantages described below.
Accordingly, an aspect of the present disclosure is to provide an electronic device and a method of controlling the electronic device using components (i.e., transducers) used for the input or output of audio signals.
Accordingly, another aspect of the present disclosure is to use transducers included in an electronic device to control the electronic device without requiring other devices (e.g., an input unit or a sensor).
Accordingly, another aspect of the present disclosure is to intuitively use transducers to perform functions of an electronic device, thereby eliminating complicated, redundant operations.
Accordingly, another aspect of the present disclosure is to reduce the installation space required for the components of an electronic device.
In accordance with an aspect of the present disclosure, an electronic device is provided. The electronic device includes a transducer, and a processor that detects a touch of an external object which is related to the transducer, and executes a function, based on the touch.
In accordance with another aspect of the present disclosure, an electronic device is provided. The electronic device includes a first transducer, a second transducer, and a processor that detects a touch of an external object which is related to at least one of the first transducer and the second transducer, performs a first preset function when the touch is related to only the first transducer, and performs a second preset function when the touch is related only to the second transducer.
In accordance with another aspect of the present disclosure, an electronic device is provided. The electronic device includes a first transducer, a second transducer, and a processor that obtains a first audio signal via the first transducer, obtains a second audio signal via the second transducer, detects a level of the first audio signal, detects a level of the second audio signal, performs a first preset function when a level difference between the level of the first audio signal and the level of the second audio signal is within a first preset range of levels, and performs a second preset function if the level difference is within a second preset range of levels.
In according with another aspect of the present disclosure, a method of controlling an electronic device is provided. The method includes detecting a touch of an external object which is related to at least one of a first transducer and a second transducer of the electronic device, performing a first preset function when the touch is related to only the first transducer, and performing a second preset function when the touch is related only to the second transducer.
The above and other aspects, features and advantages of certain embodiments of the present disclosure will be more apparent from the following detailed description, taken in conjunction with the accompanying drawings, in which:
Hereinafter, various embodiments of the present specification will be described with reference to the accompanying drawings, in which like reference numerals are used to refer similar elements. However, it should be understood that there is no intent to limit the present disclosure to the particular forms disclosed herein. Rather, the present disclosure should be construed to cover various modifications, equivalents, and/or alternatives of embodiments of the present disclosure. As used herein, the expressions “have” and “include” refer to the existence of a corresponding feature (e.g., a numeral, a function, an operation, an element, component, etc.), and do not exclude one or more additional features.
In the present disclosure, the expressions “A or B”, “at least one of A or/and B”, and “one or more of A or/and B” may include all possible combinations of the items listed. For example, the expressions “A or B”, “at least one of A and B”, and “at least one of A or B” refer to all of (1) A, (2) B, or (3) A and B.
The expressions “first”, “second”, etc. used herein may modify various components regardless of the order and/or the importance, but do not limit the corresponding components. For example, a first user device and a second user device indicate different user devices although both of them are user devices. For example, a first element may be referred to as a second element, and similarly, a second element may be referred to as a first element without departing from the scope of the present disclosure.
It should be understood that when an element (e.g., a first element) is referred to as being “connected,” or “coupled,” to another element (e.g., a second element), the element may be directly connected or coupled directly to the other element or any other element (e.g., a third element) may be interposed between them. In contrast, it may be understood that when an element (e.g., a first element) is referred to as being “directly connected,” or “directly coupled” to another element (e.g., a second element), there are no element (e.g., a third element) interposed between them.
The expression “configured to” used in the present disclosure may be used interchangeable with the expressions “suitable for”, “having the capacity to”, “designed to”, “adapted to”, “made to”, or “capable of” according to the situation. The term “configured to” may not necessarily imply “specifically designed to” in hardware. Alternatively, in some situations, the expression “device configured to” may mean that the device, together with other devices or components, “is able to”. For example, the phrase “processor adapted (or configured) to perform A, B, and C” may mean a dedicated processor (e.g. embedded processor) only for performing the corresponding operations or a generic-purpose processor (e.g., central processing unit (CPU) or application processor (AP)) that can perform the corresponding operations by executing one or more software programs stored in a memory device.
The terms used in the present disclosure are only used to describe specific embodiments, and are not intended to limit the present disclosure. As used herein, singular forms may include plural forms as well, unless the context clearly indicates otherwise. Unless defined otherwise, all terms used herein, including technical and scientific terms, have the same meaning as those commonly understood by a person skilled in the art to which the present disclosure pertains.

At step 410, the electronic device 201, configured to include at least one component (i.e., transducer), detects a touch of an external object, related to at least one transducer.
That is, at least one transducer is installed inside the electronic device 201 and is disposed adjacent to at least one opening of the electronic device 201. At least one transducer is configured to include an audio output transducer and/or an audio input transducer. For example, the audio output transducer may include the speaker 282, the receiver 284, and the earphones 286. The audio input transducer may include the microphone 288.
In order to detect a touch of an external object, related to at least one transducer, the electronic device 201 is includes an impedance detection circuit and/or a noise detection circuit. For example, the impedance detection circuit may be configured to detect impedance created when the transducer outputs an audio signal. The noise detection circuit may be configured to detect touch noise created when the transducer receives an audio signal.
At step 430, the electronic device 201 executes a related function of the electronic device 201 based on the detected touch.
That is, when the electronic device 201 detects the touch of the external object, related to at least one transducer, the electronic device 201 recognizes the touch of the external object as an input signal, and executes a related function. For example, the electronic device 201 may execute a function of its hardware (e.g., a camera 291, a transducer, etc.), software (e.g., an application 370), or firmware, or a combination thereof
For example, when the electronic device 201 operates in a camera shoot mode, the electronic device 201 may control the camera 291 to perform a shoot function, based on a touch of an external object. The electronic device 201 may be set in such a way that when the electronic device 201 detects a touch of the external object, related to at least one transducer, during an idle mode, the electronic device 201 enters a camera shoot mode.
As another example, the electronic device 201 may control the input/output of audio signals of at least one transducer, based on a touch of an external object. For example, when a ringtone, alarm clock sound or music is output via the speaker 282 of the electronic device 201, the electronic device 201 is controls the audio signals output from the speaker 282 based on a touch of the external object. That is, when the user of the electronic device 201 touches an opening adjacent to a transducer outputting the audio signals, the electronic device 201 controls the transducer to mute or block the audio signals, such as a ringtone, an alarm clock sound or music, based on the touch. In addition, when the user of the electronic device 201 touches an opening adjacent to a transducer receiving the audio signals, the electronic device 201 controls the transducer to stop receiving the audio signal.
As another example, the electronic device 201 may control functions of a specified application or specified firmware (e.g., controlling audio volume of a music application, etc.), etc., based on a touch of an external object. For example, if the electronic device 201 detects a touch of an external object, related to at least one transducer, in a lock screen state, the electronic device 201 is capable of unlocking the lock screen or locking the screen of the electronic device 201.
The electronic device 201 obtains the number of touches detected at at least one opening during a preset period of time, and executes a preset function based on the obtained number of touches. For example, if a user repeatedly touches an opening disposed adjacent to a transducer of the electronic device 201 for a preset period of time and then removes the touch therefrom, the electronic device 201 detects touch noise that arises during the period of time. Therefore, the electronic device 201 is able to obtain the number of detections of touch noise, and execute a preset function based on the obtained number of detections of touch noise. For example, the electronic device 201 may be preset in such a way that if touch noise is detected twice during a preset period of time, the electronic device 201 enables the front and rear cameras to enter an activated mode. The electronic device 201 may also be preset in such a way that if touch noise is detected three times during a preset period of time, the electronic device 201 enables the front and rear cameras to enter a beauty shot mode.
The electronic device 201 may be configured in such a way as to recognize a touch pattern for at least one opening and execute a preset function. For example, the electronic device 201 is capable of recognizing a touch pattern for an opening disposed adjacent to the transducer, e.g., a pattern of occurrence of touch noise, a change in sensitivity of touch noise, etc. The electronic device 201 is capable of comparing the recognized pattern with a preset pattern. If the electronic device 201 ascertains that the recognized pattern is identical to a preset pattern, the electronic device 201 executes a preset function, for unlocking the lock screen of the electronic device 201.
A method of controlling the electronic device 201 using various types of transducers, e.g., an audio output transducer and an audio input transducer, is explained in detail with reference to
Referring to
At step 510, the electronic device 201 receives audio output signals, and outputs the audio output signals via an audio output transducer in operation 510.
The audio output signals may be created by users, external electronic devices, external servers, base stations, etc. If the electronic device 201 receives an audio output signal, the electronic device 201 may output various types of preset audio signals, e.g., a notification sound, music, white noise, etc. An example of the audio signal output from the electronic device 201 may also be a relatively low level of sound to such an extent that the sound can be detected, e.g., a sound created when an external object physically opens/closes an opening. If the processor applies a signal of a relatively small level, e.g., 1 mV (0.001 V), to the audio output transducer, the audio output transducer may output an audio signal that has a level to such an extent that users can just hear the audio in a quiet environment.
The audio output transducer is installed inside the housing of the electronic device 201 and is disposed adjacent to at least one opening formed in one side of the housing. For example, the audio output transducer may include the speaker 282 and/or the receiver 284.
At step 520, the electronic device 201 detects a first change in impedance at a resonant frequency of the audio output transducer.
Resonance is a phenomenon where external force drives a structure at the same natural frequency of the structure and thus the structure oscillates with greater amplitude. For example, if current is applied to the diaphragm of the speaker 282 attached to a coil at the same natural frequency of the diaphragm, the diaphragm vibrates with the highest displacement. In this case, the electronic device 201 is capable of detecting a touch of an external object, using the vibration of the diaphragm with the highest displacement.
The first impedance change on a resonant frequency of the audio output transducer may be created by a touch physically applied to an opening formed adjacent to the audio output transducer. For example, if a user touches, with an external object (e.g., the finger or a tool), at least one opening which is formed in one side of the housing of the electronic device 201, the electronic device 201 creates a first impedance change on a resonant frequency of the audio output transducer disposed adjacent to the touched opening. If the touch is removed from at least one transducer where the touch occurred, the electronic device 201 may generate a first impedance change on a resonant frequency of an audio output transducer disposed adjacent to the opening from which the touch is removed.
Referring to
Referring to
When a touch is not applied to an opening formed adjacent to the audio output transducer, the impedance peak is formed between 750˜1000 Hz in which a resonant frequency is formed. In this case, when the user touches at least one opening formed in one side of the housing of the electronic device 201 the impedance peak disappears between 750˜1000 Hz in which a resonant frequency is formed. Based on this feature, the electronic device 201 is able to determine whether a physical touch is applied to an opening formed adjacent to the audio output transducer.
The electronic device 201 may further include an impedance detection circuit for detecting a change in impedance. The impedance detection circuit may be designed in such a way as to detect impedance of an audio output transducer inside the electronic device 201, i.e., an impedance change at a resonant frequency of the audio output transducer.
At step 530, the electronic device 201 performs a first preset operation after detecting the first change in impedance at the resonant frequency of the audio output transducer.
The first preset operation may be various operations (functions) that the electronic device 201 can perform based on its received input signals. Examples of the first preset operation are an operation for controlling camera-related functions (e.g., a function for entering a camera shoot mode, a function for entering a camera shoot set-up mode), an operation for unlocking the lock screen of the electronic device 201, a function for muting or blocking a ringtone when an incoming call is received, a function for controlling an audio output transducer outputting audio signals.
The electronic device 201 may have stored a degree of change in impedance according to a physical touch applied to an opening. For example, the electronic device 201, which has stored a degree of change in impedance which can occur when a physical touch is applied to an opening, may be configured in such a way that a first preset operation is not performed by an impedance change which is generated by causes other than a physical touch. Therefore, the electronic device 201 is capable of determining whether a change in impedance that occurred in the audio output transducer is caused by a physical touch applied to the opening. If the electronic device 201 ascertains that a change in impedance is caused by a physical touch, the electronic device 201 performs the first preset operation.
At step 540, the electronic device 201 detects a second change in impedance at a resonant frequency of the audio output transducer.
The second impedance change at a resonant frequency of the audio output transducer may be caused by the first impedance change. For example, if the first impedance change at a resonant frequency of an audio output transducer is caused when a touch is applied to at least one opening formed in one side of the housing of the electronic device 201, the second impedance change may occur when the touch is removed from the touched opening or openings. Alternatively, if the first impedance change at a resonant frequency of an audio output transducer is caused when a touch is removed from at least one opening formed in one side of the housing of the electronic device 201, the second impedance change may occur when a touch is re-applied to the opening or openings.
At step 550, the electronic device 201 performs a second preset operation after detecting the second impedance change at the resonant frequency of the audio output transducer.
The second preset operation may be various operations (functions) that the electronic device 201 can perform, according to the reception of input signals, based on the first operation that the electronic device 201 has performed. For example, if the first operation is an operation for controlling camera-related functions, the second preset operation may be at least one of an operation for controlling the change between modes of a shoot mode (e.g., a mode for switching between the front and rear cameras when the camera 291 captures images, a manual shoot mode, a beauty shot mode, a panorama shot mode, etc.), an operation for controlling the camera shoot settings (e.g., ISO and shutter speed settings, etc.), etc. If the first operation is an operation for unlocking the lock screen of the electronic device 201, the second preset operation may be an operation for changing the unlock screen to the lock screen. If the first operation is an operation for muting or blocking a ringtone or controlling the audio output transducer outputting an audio signal, the second-preset operation may be an operation for re-outputting the ringtone or returning the audio output transducer to the previous state before the audio output transducer was controlled.
The electronic device 201 may have stored a degree of change in impedance according to a physical touch applied to an opening. For example, the electronic device 201, which has stored a degree of change in impedance which can occur when a physical touch is applied to an opening, may be configured in such a way that a second preset operation is not performed by an impedance change which is generated by causes other than a physical touch. Therefore, the electronic device 201 is capable of determining whether a change in impedance that occurred in the audio output transducer is caused by a physical touch applied to the opening. If the electronic device 201 ascertains that a change in impedance is caused by a physical touch, the electronic device 201 performs the second preset operation.

At step 810, the electronic device 201 receives a signal for activating an audio input transducer, and activates the audio input transducer.
The signal for activating an audio input transducer may be created by users, external electronic devices, external servers, base stations, etc. The audio input transducer is installed inside the housing of the electronic device 201 and is disposed adjacent to at least one opening formed in one side of the housing. For example, the audio input transducer may include the microphone 288.
The electronic device 201 may also be controlled by at least one of a microphone of earphones connected to the electronic device 201, a microphone included in an external electronic device (e.g., a microphone of a BT headset, a microphone of a BT speaker, etc.), etc., as well as the audio input transducer of the electronic device 201.
At step 820, the electronic device 201 detects a first touch noise that occurs in the audio input transducer.
Touch noise is refers to noise, e.g., vibration, generated when the user opens or closes, with a finger, for example, an opening formed adjacent to the audio input transducer. Touch noise may mix with signals. The electronic device 201 detects the first touch noise that occurs when a physical touch is applied to an opening formed adjacent to the audio input transducer. For example, if the user of the electronic device 201 touches, with a finger and/or a tool, at least one opening formed in one side of the housing of the electronic device 201, the first touch noise may arise at the audio input transducer disposed adjacent to the touched opening.
The electronic device 201 may further include a noise detection circuit for detecting the first touch noise that occurs at the audio input transducer.

The first preset operation may be various operations (functions) that the electronic device 201 can perform based on received input signals. Examples of the first preset operation are an operation for controlling camera-related functions (e.g., a function for entering a camera shoot mode, a function for entering a camera shoot set-up mode), an operation for unlocking the lock screen of an electronic device 201, a function for muting or blocking a ringtone when an incoming call is received, a function for controlling an audio output transducer outputting audio signals.
The electronic device 201 may have stored a degree of change in inflow of external environment noise or touch noise according to a physical touch applied to an opening. For example, the electronic device 201, which has stored a degree of change in inflow of external environment noise or touch noise, which can occur when a physical touch is applied to an opening, may be configured in such a way that a first preset operation is not performed by a change in inflow of external environment noise or touch noise which is generated by causes other than a physical touch. Therefore, the electronic device 201 is capable of determining whether a change in inflow of external environment noise or touch noise that occurred in the audio input transducer is caused by a physical touch applied to the opening. If the electronic device 201 ascertains that a change in inflow of external environment noise or touch noise is caused by a physical touch, the electronic device 201 performs the first preset operation.
At step 840, the electronic device 201 detects a second touch noise that occurs in the audio input transducer.
The second touch noise that occurs in the audio input transducer may be caused by the first touch noise. For example, if the first touch noise that occurred in the audio input transducer is caused when a touch is applied to at least one opening formed in one side of the housing of the electronic device 201, the second touch noise may occur when the touch is removed from the touched opening or openings. If the first touch noise that occurred in an audio input transducer is caused when a touch is removed from at least one opening formed in one side of the housing of the electronic device 201, the second touch noise may occur when a touch is re-applied to the opening or openings.
The electronic device 201 may be implemented in such a way as to execute a preset operation by detecting a change in flow of external environment noise, caused according to the opening/closing operation of an opening disposed adjacent to the audio input transducer, instead of detecting the first touch noise and the second touch noise. For example, since an opening disposed adjacent to the audio input transducer is generally exposed to an external environment and receives external environment noise, if the opening is touched by a user, it may block a certain amount of external environment noise by the user's touch.

The second preset operation may be various operations (functions) that the electronic device 201 can perform, according to the reception of input signals, based on the first operation that the electronic device 201 has performed. For example, if the first operation is an operation for controlling camera-related functions, the second preset operation may be at least one of an operation for controlling the change between modes of a shoot mode (e.g., a mode for switching between the front and rear cameras when the camera 291 captures images, a manual shoot mode, a beauty shot mode, a panorama shot mode, etc.), an operation for controlling the camera shoot settings (e.g., ISO and shutter speed settings, etc.), etc. If the first operation is an operation for unlocking the lock screen of the electronic device 201, the second preset operation may be an operation for changing the unlock screen to the lock screen. If the first operation is an operation for muting or blocking a ringtone or controlling the audio output transducer outputting an audio signal, the second-preset operation may be an operation for re-outputting the ringtone or returning the audio output transducer the previous state before the audio output transducer was controlled.
The electronic device 201 may have stored a degree of change in inflow of external environment noise or touch noise according to a physical touch applied to an opening. For example, the electronic device 201, which has stored a degree of change in inflow of external environment noise or touch noise which can occur when a physical touch is applied to an opening, may be configured in such a way that a second preset operation is not performed by a change in inflow of external environment noise or touch noise which is generated by causes other than a physical touch. Therefore, the electronic device 201 is capable of determining whether a change in inflow of external environment noise or touch noise that occurs in the audio input transducer is caused by a physical touch applied to the opening. If the electronic device 201 ascertains that a change in inflow of external environment noise or touch noise is caused by a physical touch, the electronic device 201 performs the second preset operation.
In various embodiments of the present disclosure, the electronic device 201 may be configured to detect a touch which is applied to or removed from an opening disposed adjacent to the audio input transducer and to perform a first or second preset operation, based on the detection result.

In this case, the processor 210 controls the camera 291 to perform a shoot function, based on the touch, when the electronic device 201 operates in a camera shoot mode or enter a camera shoot mode, based on the touch, when the electronic device 201 operates in an idle mode.

It should also be understood that the more audio input/output transducers included in the electronic device 201, the more functions that can be set to be performed.

At step 1301, the electronic device 201 detects one or more touches of an external object related to the first and/or second transducers.
For example, at least two transducers are placed inside the housing of the electronic device 201 and are, respectively, disposed adjacent to at least two openings. For example, at least two transducers include and audio output transducer and/or an audio input transducer.

The first transducer may be implemented with an audio output transducer and/or an audio input transducer. For example, the electronic device 201 may detect a change in impedance via the audio output transducer, and determine a touch related to the first transducer. The electronic device 201 may also detect noise via the audio input transducer, and determine a touch related to the first transducer.
If the electronic device 201 ascertains that the detected touch of an external object is related to the first transducer then, at step 1305, the electronic device 201 determines if the detected touch of the external object is also related to the second transducer. That is, the electronic device 201 determines whether both the touch is detected on both first transducer and the second transducer.
If the electronic device 201 ascertains that the detected touch of the external object is not related to the second transducer (i.e., the detected touch is only related to the first transducer) then, at step 1309, the electronic device 201 performs a first preset function.

On the other hand, if the electronic device 201 ascertains that the detected touch of the external object is related to a second transducer (i.e., the detected touch is related to both the first transducer and the second transducer) then, at step 1311, the electronic device 201 performs a third preset function.

At step 1501, the electronic device 201 obtains a first audio signal via a first transducer. The first transducer may include an audio input transducer. For example, if the electronic device 201 detects a touch of an external object applied to the first transducer, the electronic device 201 obtains a first audio signal according to the occurrence of touch noise.
At step 1503, the electronic device 201 is obtains a second audio signal via a second transducer. The second transducer may include an audio input transducer which differs from that included in the first transducer. For example, if the electronic device 201 detects a touch of an external object applied to the second transducer, the electronic device 201 obtains a second audio signal according to the occurrence of touch noise. At step 1505, the electronic device 201 detects the levels of the first obtained audio signal and the second obtained audio signal. For example, a level of an audio signal may refer to a level difference between a level of an audio signal created according to a touch of an external object related to a transducer and a level of an audio signal created by only the inflow of external environment noise. Additionally, the electronic device 201 is capable of distinguishing between degrees of a touch of an external object related to a transducer, using the level difference. For example, the electronic device 201 is capable of distinguishing between a touch completely closing an opening formed adjacent to the transducer and a touch partially closing the opening. Therefore, the electronic device 201 may have stored a level difference when an opening formed adjacent to the transducer is completely closed and a level difference when the opening is partially closed.
At step 1507, the electronic device 201 determines whether the difference between the levels of the first and second audio signals is within a preset range of levels. The electronic device 201 may have stored a preset range of levels. If the electronic device 201 ascertains that the difference between levels of the first and second audio signals is within a preset range of levels then, at step 1509, the electronic device 201 performs a first preset function. The first preset function may be a function for increasing/decreasing the sensitivity to an input audio signal. The first preset function may be a camera-related function (e.g., a function for entering a camera shoot mode, a function for entering a camera shoot set-up mode), a function for unlocking the lock screen of the electronic device 201, a function for muting or blocking a ringtone when an incoming call is received, etc.
On the other hand, if the electronic device 201 ascertains that the difference between levels of the first and second audio signals is not within the preset range of levels then, at step 1511, the electronic device 201 is capable of determining whether the difference between the levels of the first and second audio signals is within a second preset range of levels. The electronic device 201 may have stored a second preset range of level. If the electronic device 201 ascertains that the difference between levels of the first and second audio signals is within the second preset range of levels then, at step 1513, the electronic device 201 performs a second preset function. The second preset function may be a function for decreasing/increasing the sensitivity to an input audio signal. If the first preset function is a function for unlocking the lock screen of the electronic device 201, the second preset function may be a function for changing the unlock screen to the lock screen. If the first preset function is a function for muting or blocking a ringtone, the second preset function may be a function for re-outputting the ringtone, etc.
On the other hand, if the electronic device 201 ascertains that the difference between levels of the first and second audio signals is not within the second preset range of levels then, at step 1515, the electronic device 201 performs a third preset function. The third preset function may be a function for muting/blocking an output audio signal or a function for blocking an input audio signal. That is, the third preset function may be a function for stopping the control of the electronic device 201 using the transducer.
In various embodiments of the present disclosure, the electronic device 201 is configured to include a first transducer, a second transducer, and the processor 210.
