Description

Technical Field

[0001] The present application relates to an electronic device, and more specifically, to an earphone. Background Art

[0002] refer to Figure 1 As shown, generally, headphones with touch function usually have an external touch sensor (not shown) and a touch pad 12 to control the headphones. The touch function is operated in that the user touches the headphone housing with a finger to perform the touch action. However, since the design of the antenna 14 in the headphones also uses a conductive pad, the design of the touch pad 12 will limit the design of the antenna 14, which may cause certain interference to the antenna 14, and it is necessary to consider designing a clearance area to avoid interference. However, designing a clearance area will increase the size of the headphones. In addition, the touch sensor and touch pad 12 in general headphones will also lead to higher costs.

[0021] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application belong to the scope of protection of this application.

[0022] The following disclosure provides many different embodiments or examples for realizing different features of the provided subject matter. Specific examples of components and arrangements will be described below to simplify the present invention. Of course, these are merely examples and are not intended to limit the present invention. For example, in the following description, forming a first component above or on a second component may include an embodiment in which the first component and the second component are in direct contact, and may also include an embodiment in which an additional component is formed between the first component and the second component so that the first component and the second component may not be in direct contact. Moreover, the present invention may repeatedly refer to numbers and / or letters in various examples. This repetition is only for simplicity and clarity, and does not itself represent the relationship between the various embodiments and / or configurations discussed.

[0023] In addition, the embodiments and features in the embodiments of the present application may be combined with each other without conflict. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0024] According to an embodiment of the present application, an electronic device is provided. Figure 2 is a block diagram of an electronic device 100 according to an embodiment of the present application. Figure 2 As shown, the electronic device 100 may include a receiving unit 110 and a judging unit 120 that are signal-connected to each other. The receiving unit 110 may be used to receive a vibration signal from a user, and may transmit the vibration signal to the judging unit 120. According to an embodiment of the present application, the vibration signal may include a non-voice action instruction, such as an action instruction generated by an action performed by the user (such as a tapping action). The judging unit 120 may be used to determine whether the vibration signal is a non-voice action instruction based on the frequency of the vibration signal, so that the electronic device 100 can execute the action instruction.

[0025] In the above-mentioned electronic device 100, the vibration signal from the user can be obtained by the receiving unit 110, and the corresponding action command can be judged accordingly, so that the electronic device 100 can be controlled by the user's action, without saving control elements (such as touch sensors and touch pads) in the electronic device 100, thereby saving the design space of the electronic device 100. The saved space can be used to increase the antenna design space or increase the antenna clearance area.

[0026] In some embodiments, the receiving unit 110 may include a bone conduction sensor (also referred to as a bone conduction microphone). The principle of a bone conduction sensor is to use a film of a specific specification so that it can receive vibration signals transmitted by the user's bones instead of receiving vibration signals (such as sound) transmitted by air.

[0027] In some embodiments, the electronic device 100 may be a headset 100' (see Figure 3A ). Figure 3A Optional positions P1, P2, and P3 of the bone conduction sensor 110' in the earphone 100' are shown. The bone conduction sensor 110' can be located at the edge area of ​​the earphone 100' so that the bone conduction sensor 110' can be close to the head bone of the user. Figure 3B As shown, when the user wears the headset 100', the bone conduction sensor 110' may be adjacent to the user's zygomatic bone 202, that is, the bone conduction sensor 110' is located at a position P2 on the headset 100' that is closest to the zygomatic bone 202. In another embodiment, when the user wears the headset 100', the bone conduction sensor 110' may be adjacent to the user's temporal bone 204, that is, the bone conduction sensor 110' is located at a position P1 on the headset 100' that is closest to the temporal bone 204.

[0028] Both the vibration signal of the user's voice and the vibration signal of non-voice can be received by the bone conduction sensor 110' through the user's head bones. Therefore, only one bone conduction sensor 110' can be set in the headset 100'. Existing headsets are usually equipped with at least two air conduction microphones, one of which is used for calls and the other is used to receive external signals for example for ANC (Active Noise Cancellation). However, the present application can be provided with only one bone conduction sensor 110', thereby further saving the design space in the headset 100'. The present application can be implemented by replacing the air conduction microphone in the existing headset with a bone conduction sensor 110', so there is no need to specially design the existing headset, so that the present invention can be applied to various types of headsets. In addition, the bone conduction sensor 110' receives signals in a vibration manner, that is, there is no wind noise problem and no sound guide device is required.

[0029] In some embodiments, the vibration signal received by the bone conduction sensor 110' can be caused by the user's action. For example, the vibration signal can be caused by the user tapping the cheek bone (such as the zygomatic bone 202) with a finger. For another example, the vibration signal can also be triggered by the user's teeth biting. During use, the bone conduction sensor 110' is used in the headset 100'. The user wears the headset 100' on the ear. The user can trigger vibration by tapping a position such as the zygomatic bone 202 with a finger. The vibration is transmitted to the bone conduction sensor 110' through the cheek bone and the headset shell. After receiving the vibration, the bone conduction sensor 110' converts it into a vibration signal in a mechanical signal mode. The bone conduction sensor 110' is arranged at a position P2 or P1 close to the zygomatic bone 202 or the temporal bone 204, so that the vibration signal received by the bone conduction sensor 110' can be relatively simple, not easy to be mistakenly connected with other daily actions, and the relatively large area makes it easier to perform the tapping action.

[0030] Return to reference Figure 2 , the judgment unit 120 may specifically include an operator unit 122, and the operator unit 122 may determine whether the received vibration signal is a voice command from the user's speech or a non-voice action command from the user by training feature values ​​with an algorithm. Specifically, as described above, the receiving unit 110 may receive both a vibration signal of the user's voice and a non-voice vibration signal. Furthermore, since the frequencies of the voice vibration signal and the non-voice vibration signal are different, the operator unit 122 may determine whether the vibration signal is a voice vibration signal or a non-voice vibration signal based on the frequency of the received vibration signal by training feature values ​​with an algorithm. This determination method of the operator unit 122 may reduce the occurrence of false actions of the bone-conducted vibration control.

[0031] When the calculation subunit 122 determines that the received vibration signal is a non-voice vibration signal, the non-voice vibration signal can be transmitted to the extraction subunit 124. The extraction subunit 124 can be used to extract the voice vibration signal and the non-voice vibration signal from the non-voice vibration signal. The extracted non-voice vibration signal can be used to distinguish the action instruction, and the extracted voice vibration signal can be used to distinguish the voice instruction. The extraction subunit 124 can also be used to extract the frequency, number or combination of the non-voice vibration signal. The number can be the number of actions (such as tapping actions) performed by the user.

[0032] In addition, the judgment unit 120 may further include a mapping subunit 126. The mapping subunit 126 may be used to map the non-voice vibration signal to a corresponding action instruction, that is, the action instruction corresponding to the non-voice vibration signal may be determined. In some embodiments, the mapping subunit 126 may determine the corresponding action instruction based on the number of non-voice vibration signals. In some embodiments, the action instruction includes at least one of answering a call and active noise reduction.

[0033] For example, when the user taps the cheek once, the extraction subunit 124 can determine that the number of non-voice vibration signals is one time, and the mapping subunit 126 can determine that the corresponding action instruction is to tap once, so that the corresponding operation of answering / hanging up the phone can be performed. For another example, when the user taps the cheek twice, the extraction subunit 124 can determine that the number of non-voice vibration signals is two times, and the mapping subunit 126 can determine that the corresponding action instruction is to tap twice, so that the corresponding operation of playing (Play) / pausing (Pause) the phone can be performed. For another example, when the user taps the cheek three times, the extraction subunit 124 can determine that the number of non-voice vibration signals is three times, and the mapping subunit 126 can determine that the corresponding action instruction is to tap three times, so that the corresponding operation of ANC on / off can be performed.

[0034] The electronic device 100 may further include an execution unit 130 connected to the judgment unit 120 by signal. The execution unit 130 may execute the action instruction determined by the judgment unit 120 to perform a corresponding operation (e.g., answering a call, active noise reduction, etc.). The execution unit 130 may also execute a corresponding operation (e.g., speaking on the phone) according to the voice instruction corresponding to the vibration signal of the voice. In some embodiments, the execution unit 130 may simultaneously execute the operations corresponding to the action instruction and the voice instruction.

[0035] In addition, in some embodiments, the electronic device 100 may further include a preprocessing unit 150, which is connected between the receiving unit 110 and the judging unit 120 and is used to preprocess the vibration signal. The preprocessing unit 150 includes at least one of a filtering subunit 152 for filtering noise and an amplifying subunit 154 for amplifying the signal. In some embodiments, the amplifying subunit 154 may include a low noise amplifier (LNA).

[0036] In some embodiments, the electronic device 100 may further include a pronunciation unit (not shown), which may be used to send a confirmation notification to the user according to the action instruction. In some embodiments, the electronic device 100 may further include a vibration unit (not shown), which may be used to send a confirmation notification to the user according to the action instruction. The vibration unit includes a vibration motor, which may generate vibration to send a confirmation notification. The vibration unit is adjacent to the user's temporal bone. By designing a confirmation mechanism, misoperation can be avoided. For example, when the user triggers an action instruction through an action, a confirmation notification may be sent through the pronunciation unit or the vibration unit.

[0037] The electronic device 100 provided in the present application, such as the earphone 100', can utilize the existing microphone design of the earphone, change the microphone sound collection principle (i.e. replace the existing air conduction microphone with a bone conduction sensor), and then add calculation to achieve contactless control of the earphone to adapt to the future trend of contactless control.

[0038] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application should be included in the protection scope of the present application.
