DETAILED DESCRIPTION

[0019] Various exemplary embodiments of the present application will now be described in detail with reference to the accompanying drawings. It should be noted that unless otherwise specifically stated, the relative arrangements of components and steps, numerical expressions and numerical values set forth in these embodiments do not limit the scope of the present application.

[0020] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the present disclosure, its application, or uses.

[0021] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0022] In all examples shown and discussed herein, any specific values should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0023] It should be noted that like reference numerals and letters refer to like items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0024] like Figure 1 As shown, the present application provides an OWS headset 10, including a first speaker 102, a first microphone 103 and a processor 101, wherein: The first microphone 103 is arranged at the sound leakage position, and is used to pick up the ambient sound to obtain the ambient audio signal, and the ambient audio signal at least includes the sound leakage audio signal at the sound leakage position of the OWS headset; The processor 101 is connected to the first speaker 102 and the first microphone 103 respectively. The processor 101 is used to obtain the ambient audio signal picked up by the first microphone 103, generate a leakage cancellation audio signal based on the ambient audio signal, and control the first speaker 102 to play the leakage cancellation audio signal. The leakage cancellation audio signal has the same amplitude and opposite phase as the leakage audio signal. The first speaker 102 is disposed adjacent to the first microphone 103 and is configured to play a sound leakage cancellation audio signal under the control of the processor 101 .

[0025] It is understandable that the OWS earphones involved in this application also have the functions of traditional OWS earphones, that is, Figure 2 As shown, the OWS headset also includes a second speaker 104 and a second microphone 105, wherein the second speaker 104 is a speaker for realizing the traditional playback function of the OWS headset, for example, for playing the valid audio signal (audio and video call voice, multimedia audio, etc.) received by the OWS headset, and the second microphone 105 is used to pick up the sound signal of the wearer of the OWS headset.

[0026] On the basis of the second speaker 104 and the second microphone 105, the OWS headset provided by the present application further includes a first speaker 102, a first microphone 103 and a processor 101. Among them, the processor 101 can reuse the processor 101 in the traditional OWS headset, of course, it can also be an additional processor 101 provided on the basis of the traditional OWS headset. The processor 101 can be exemplarily an MCU. Taking the processor 101 reused in the traditional OWS headset as an example, Figure 2 As shown, the processor 101 is also connected to a second speaker 104 and a second microphone 105 .

[0027] In this embodiment, the first microphone 103 is arranged at the sound leakage position, and the first speaker 102 is arranged adjacent to the first microphone 103 as close as possible. The sound leakage position is the position where the sound leakage audio signal is most obvious, such as the position where the sound leakage volume is the largest, which can be determined based on experience or experiments. On this basis, the first microphone 103 can collect the sound leakage audio signal. It can be understood that when there is noise in the environment where the OWS headset is located, the first microphone 103 can also pick up the noise signal. Based on this, the sound signal picked up by the first microphone 103 in the OWS headset provided by this application is recorded as an ambient audio signal, and the ambient audio signal at least includes the sound leakage audio signal at the sound leakage position of the OWS headset.

[0028] In one embodiment of the present application, the first microphone 103 is located on the central axis of the OWS headset. Figure 3 As shown, when the first microphone 103 is located on the central axis of the OWS headset, the first microphone 103 can pick up leaked audio signals from all directions. Figure 3 The dotted line in FIG is the central axis of the OWS headset, and the arrows located around the first microphone 103 are used to illustrate the propagation direction of the leakage audio signal.

[0029] Based on the above content, in the OWS headset approved by this application, the processor 101 is specifically used to execute the following steps S10 to S30.

[0030] Step S10: Acquire the ambient audio signal picked up by the first microphone 103.

[0031] Step S20: generating a sound leakage cancellation audio signal according to the ambient audio signal.

[0032] Among them, such as Figure 3 As shown, the leakage cancellation audio signal has the same amplitude as the leakage audio signal and an opposite phase.

[0033] In one embodiment of the present application, the ambient audio signal is directly regarded as a leakage audio signal. Based on this, an audio signal with the same amplitude and opposite phase as the ambient audio signal is generated according to the ambient audio signal, which is recorded as a leakage cancellation audio signal.

[0034] Step S30: Control the first speaker 102 to play the sound leakage canceling audio signal.

[0035] Based on step S30 above, the first speaker 102, under the control of the processor 101, plays the sound leakage cancellation audio signal. This cancels out the ambient sound signal at the leakage location. Because the ambient sound signal includes the leakage audio signal, the leakage audio signal is canceled out. This prevents the sound leakage produced by the OWS headset from being heard by nearby users, preventing privacy breaches and disrupting nearby users.

[0036] In addition, in one embodiment of the present application, the first speaker 102 is located on the central axis of the OWS headset. Figure 3 As shown, when the first speaker 102 is located on the central axis of the OWS headset, the leakage-canceling audio signal played by the first speaker 102 can propagate in all directions to cancel out the leakage-canceling audio signals in all directions. The arrows around the first speaker 102 indicate the propagation directions of the leakage-canceling audio signal.

[0037] The present application provides an OWS headset, comprising: a first speaker, a first microphone, and a processor, wherein: the first microphone is arranged at a sound leakage position, and is used to pick up ambient sound to obtain an ambient audio signal, and the ambient audio signal includes at least a leakage audio signal at the sound leakage position of the OWS headset; the processor is connected to the first speaker and the first microphone respectively, and the processor is used to obtain the ambient audio signal picked up by the first microphone, generate a leakage cancellation audio signal according to the ambient audio signal, and control the first speaker to play the leakage cancellation audio signal, and the leakage cancellation audio signal has the same amplitude and opposite phase as the leakage audio signal; the first speaker is arranged adjacent to the first microphone, and is used to play the leakage cancellation audio signal under the control of the processor. The OWS headset can achieve the cancellation of leakage audio signals. In this way, the leakage sound generated by the OWS headset will not be heard by people around, so it will not cause privacy leakage and will not disturb people around.

[0038] In one embodiment of the present application, Figure 2 As shown, the OWS headset further includes a second speaker 104, and the processor 101 is connected to the second speaker 104. The processor 101 is further configured to execute any of the following steps S40 to S70. It should be noted that any of the following steps S40 to S70 is executed before the above step S10.

[0039] Step 40 : When the second speaker 104 plays a valid audio signal, the first microphone 103 and the first speaker 102 are turned on.

[0040] In this embodiment, when the second speaker 104 plays a valid audio signal, the OWS headset may experience sound leakage. Therefore, when the second speaker 104 plays a valid audio signal, the first microphone 103 and the first speaker 102 are activated, thereby canceling out the leaked audio signal through steps S10 to S30. This prevents the first microphone 103 and the first speaker 102 from being activated unnecessarily, thereby reducing the power consumption of the OWS headset.

[0041] Corresponding to the above step S40 , when the second speaker 104 does not play a valid audio signal, the first microphone 103 and the first speaker 102 are turned off.

[0042] Step S50 : obtaining the actual sound pressure level of the effective audio signal, and turning on the first microphone 103 and the first speaker 102 when the actual sound pressure level is greater than the preset sound pressure level.

[0043] In this embodiment, the preset sound pressure level is the minimum sound pressure level of the effective audio signal when the OWS headset generates a leakage audio signal that can be heard by people around due to the effective audio signal played by the second speaker 104. On this basis, when the actual sound pressure level of the effective audio signal is greater than the preset sound pressure level, the leakage audio signal has the possibility of privacy leakage and interference with people around. Based on this, when the actual sound pressure level of the effective audio signal played by the second speaker 104 is greater than the preset sound pressure level, the first microphone 103 and the first speaker 102 are turned on, and then the leakage audio signal is offset through the above steps S10 to S30. In this way, the first microphone 103 and the first speaker 102 can be avoided from being turned on unnecessarily, thereby reducing the power consumption of the OWS headset.

[0044] Corresponding to the above step S50 , when the actual sound pressure level is less than or equal to the preset sound pressure level, the first microphone 103 and the first speaker 102 are turned off.

[0045] Step S60 , detecting whether the valid audio signal contains privacy information, and if so, turning on the first microphone 103 and the first speaker 102 .

[0046] In one embodiment of the present application, the semantics corresponding to the valid audio signal can be identified, and it can be further determined whether the semantics include preset sensitive words, such as passwords, ID numbers, etc. If included, it is determined that the valid audio signal contains privacy information. In the case where the valid audio signal contains privacy information, there is a possibility that people around can learn the privacy information through the leaked audio signal. Based on this, in the case where the valid audio signal contains privacy information, the first microphone 103 and the first speaker 102 are turned on, and then the leakage audio signal is offset through the above steps S10 to S30. In this way, while solving the problem of privacy leakage, the first microphone 103 and the first speaker 102 can be avoided from being turned on unnecessarily, thereby reducing the power consumption of the OWS headset.

[0047] Corresponding to the above step S60 , when the valid audio signal does not contain the privacy information, the first microphone 103 and the first speaker 102 are turned off.

[0048] In step S70, the OWS headset further includes a switch control, and the processor 101 is connected to the switch control. The processor 101 is further configured to detect whether the switch control is triggered, and when the switch is triggered, turn on the first microphone 103 and the first speaker 102.

[0049] In this embodiment, if Figure 2 As shown, the OWS headset also includes a switch control, which can be a physical button or a touch button. The switch control is used for the user of the OWS headset to trigger according to needs. For example, when the user's conversation through the OWS headset involves private information, or when the user is in a quiet environment, the switch control can be triggered to turn on the first microphone 103 and the first speaker 102, and then cancel the leaked audio signal through the above steps S10 to S30. In this way, the first speaker 102 and the first microphone 103 can be turned on when the user needs it, which avoids the first microphone 103 and the first speaker 102 being turned on when it is not necessary, thereby reducing the power consumption of the OWS headset.

[0050] The present application also provides a method for canceling sound leakage from an OWS headset, which is applied to the OWS headset provided in any of the above embodiments. Figure 4 As shown, the OWS earphone sound leakage cancellation method provided in this application includes the following steps S410 to S430.

[0051] Step S410: Acquire an ambient audio signal picked up by a first microphone, where the ambient audio signal at least includes a leaked audio signal at a sound leakage position of the OWS headset.

[0052] Step S420: generating a sound leakage cancellation audio signal according to the ambient audio signal, wherein the sound leakage cancellation audio signal has the same amplitude and opposite phase as the sound leakage audio signal; Step S430: Control the first speaker to play the sound leakage canceling audio signal.

[0053] It should be noted that the specific implementation of the above steps S410 to S430 is the same as the specific implementation of the above steps S10 to S30, and will not be repeated here.

[0054] In one embodiment of the present application, the OWS earphone sound leakage cancellation method provided by the present application further includes any one of the following steps S411 to S414 before the above-mentioned step S410.

[0055] Step S411 : when the second speaker plays a valid audio signal, turn on the first microphone and the first speaker.

[0056] Step S412: obtaining an actual sound pressure level of the effective audio signal, and turning on the first microphone and the first speaker when the actual sound pressure level is greater than a preset sound pressure level.

[0057] Step S413 : detecting whether the valid audio signal contains privacy information, and if so, turning on the first microphone and the first speaker.

[0058] Step S414: detecting whether the switch control is triggered, and turning on the first microphone and the first speaker if the switch is triggered.

[0059] It should be noted that the specific implementation of the above-mentioned step S411 is the same as the specific implementation of the above-mentioned step S40, the specific implementation of the above-mentioned step S412 is the same as the specific implementation of the above-mentioned step S50, the specific implementation of the above-mentioned step S413 is the same as the specific implementation of the above-mentioned step S60, and the specific implementation of the above-mentioned step S414 is the same as the specific implementation of the above-mentioned step S70, which will not be repeated here.

[0060] In one embodiment of the present application, the above-mentioned step S420 is specifically implemented through the following steps S421 to S423.

[0061] Step S421: When the OWS is in a non-noise reduction mode, extract a leakage audio signal from the ambient audio signal.

[0062] Step S422: When the OWS headset is in the noise reduction mode, the ambient audio signal is determined as a leakage audio signal.

[0063] In this embodiment, when the OWS is in a non-noise reduction mode, it indicates that the user of the OWS headset has a need to perceive the external environmental noise, for example, the user of the OWS headset is in a waiting room and needs to listen to the information played by the station loudspeaker. On this basis, since the ambient audio signal collected by the first microphone contains external environmental noise, if the ambient audio signal is directly regarded as a leakage audio signal, through the above steps S420 and S430, there is a problem of weakening the external environmental noise, resulting in the user being unable to perceive the external environmental noise in a timely and accurate manner. In order to avoid the occurrence of this problem, when the OWS headset is in a non-noise reduction mode, it is necessary to extract the real leakage audio signal from the ambient audio signal to offset only the real leakage audio signal.

[0064] Correspondingly, when the OWS headset is in noise reduction mode, it means that the user of the OWS headset does not need to perceive the external environmental noise. At this time, although the ambient audio signal contains external environmental noise, the ambient audio signal can also be directly determined as a leakage audio signal.

[0065] Step S423: Generate a leakage-cancelling audio signal according to the leakage audio signal.

[0066] In this embodiment, an audio signal having the same amplitude and opposite phase as the leakage audio signal is generated according to the leakage audio signal obtained in step S422 or step S421 as the leakage cancellation audio signal.

[0067] In one embodiment of the present application, the extraction of the leakage audio signal from the ambient audio signal in the above step S421 is specifically implemented through the following steps S421 - 1 and S421 - 2.

[0068] Step S421 - 1 : determining audio features of the valid audio signal according to the valid audio signal played by the second speaker.

[0069] Step S421 - 2 : extracting the leakage audio signal from the ambient audio signal according to the audio signal characteristics.

[0070] It is understood that the leaked audio signal is generated by the effective audio signal leaking into the external environment. Therefore, the audio characteristics of the leaked audio signal are the same as those of the effective audio signal (e.g., frequency, timbre, pitch, etc.). Based on this, the audio signal characteristics of the effective audio signal are first determined based on the effective audio signal. Furthermore, the components of the ambient audio signal that are consistent with the determined audio signal characteristics are extracted to obtain the leaked audio signal.

[0071] This application provides a method for extracting a leakage audio signal from an ambient audio signal through the above-mentioned steps 421-1 and S421-2.

[0072] The present application also provides an OWS earphone sound leakage compensation device 500, which is applied to an OWS earphone provided by any of the above OWS earphone embodiments, such as Figure 5 As shown, the OWS earphone sound leakage compensation device 500 includes: An acquisition module 510 is configured to acquire an ambient audio signal picked up by the first microphone, where the ambient audio signal includes at least a leaked audio signal at a sound leakage position of the OWS headset; A generating module 520 is configured to generate a sound leakage cancellation audio signal according to the ambient audio signal, wherein the sound leakage cancellation audio signal has the same amplitude and opposite phase as the sound leakage audio signal; The control module 530 is configured to control the first speaker to play the sound leakage canceling audio signal.

[0073] In one embodiment of the present application, the OWS earphone sound leakage cancellation device 500 provided by the present application further includes: An activation module, configured to activate the first microphone and the first speaker when the second speaker plays a valid audio signal; Alternatively, obtaining an actual sound pressure level of the effective audio signal, and turning on the first microphone and the first speaker when the actual sound pressure level is greater than a preset sound pressure level; Alternatively, detecting whether the valid audio signal contains privacy information, and if so, turning on the first microphone and the first speaker; Alternatively, it is detected whether the switch control is triggered, and if the switch is triggered, the first microphone and the first speaker are turned on.

[0074] In one embodiment of the present application, the generating module 520 is specifically configured to: extract the leakage audio signal from the ambient audio signal when the OWS is in a non-noise reduction mode; When the OWS headset is in noise reduction mode, the ambient audio signal is determined as a leakage audio signal; A leakage-cancelling audio signal is generated according to the leakage-audio signal.
