Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.

Referring to fig. 1, an embodiment of the present application provides a noise reduction system 10 for a wireless noise reduction earphone. The noise reduction system 10 of the wireless noise reduction earphone comprises a feedforward noise reduction channel 11, a feedback noise reduction channel 13 and an audio output module 15. The feedforward noise reduction channel 11 is used for collecting noise outside the ear canal, and performing feedforward noise reduction processing on the collected noise. The feedback noise reduction channel 13 is used for collecting noise in the ear canal and performing feedback noise reduction processing on the collected noise. The audio signal output after the feedforward noise reduction processing by the feedforward noise reduction channel 11, the audio signal output after the feedback noise reduction processing by the feedback noise reduction channel 13, and the audio signal to be played are subjected to data fusion or superposition, then transmitted to the audio output module 15, and output after being processed by the audio output module 15. It should be noted that the audio signal to be played refers to an audio signal that a user of the wireless noise reduction earphone wants to play with the wireless noise reduction earphone, and the noise refers to another audio signal that can interfere with the audio signal to be played. Under the wireless earphone on state of making an uproar that falls, no matter whether play music through the wireless earphone of making an uproar that falls, the noise can derive from various environment sounds, including the voice of people, the sound of object collision, the cracked sound of object, the sound of other playback devices broadcast etc..

The feedforward noise reduction path 11 includes a feedforward microphone 111, a first analog-to-digital converter 113 in signal connection with the feedforward microphone 111, and a feedforward ANC (active noise control) filter 115 in signal connection with the first analog-to-digital converter 113. The feedforward microphone 111 is located outside the ear canal of the wearer when the wireless noise reduction earphone is worn, and is used to pick up noise outside the ear canal (e.g., ambient noise). The feedforward microphone 111 converts the collected noise into an analog electrical signal and transmits the analog electrical signal to the first analog-to-digital converter 113. The first analog-to-digital converter 113 converts the analog electrical signal into a digital signal and transmits the digital signal to the feedforward ANC filter 115. The feedforward ANC filter 115 performs feedforward noise reduction processing on the digital signal, and then outputs the feedforward noise-reduced audio signal.

In this embodiment, the feedforward noise reduction channel 11 further comprises a first low-pass and down-sampling filter 114 connected between the first analog-to-digital converter 113 and the feedforward ANC filter 115. The analog-to-digital converter 113 usually works at a higher sampling rate, for example, 24.576M samples/sec, and in order to make the feedforward ANC filter work at a lower sampling rate, for example, 384K samples/sec, the first low-pass and down-sampling filters are used to reduce the sampling rate of the feedforward ANC filter, thereby reducing the power consumption and the order of the ANC filter, thereby reducing the area of the noise reduction chip, facilitating the miniaturization of the wireless noise reduction earphone, improving the portability thereof, and reducing the cost. The first analog-to-digital converter 113 transmits the digital signal to the first low-pass and down-sampling filter 114 after converting the analog electric signal into the digital signal. The first low-pass and down-sampling filter 114 filters and down-samples the digital signal, and then transmits the sampled digital signal to the feedforward ANC filter 115 for noise reduction.

It will be appreciated that the feedforward noise reduction path 11 may also include a first analog gain module 112 connected between the feedforward microphone 111 and the first analog-to-digital converter 113. The feedforward microphone 111, after converting the collected noise into an analog electrical signal, transmits the analog electrical signal to the first analog gain module 112. The first analog gain module 112 adjusts the analog electrical signal to increase the signal-to-noise ratio and increase the output power, and then transmits the adjusted analog electrical signal to the first analog-to-digital converter 113.

The structure of the feedback noise reduction channel 13 is similar to that of the feedforward noise reduction channel 11, and specifically, the feedback noise reduction channel 13 includes a feedback microphone 131, a second analog-to-digital converter 133 connected to the feedback microphone 131, and a feedback ANC filter 135 connected to the second analog-to-digital converter 133. The feedback microphone 131 is located in the ear canal of the wearer when the wireless noise reduction earphone is worn, and is used for collecting noise (including but not limited to echo signals of sounds played by a speaker of the wireless noise reduction earphone, for example, echo signals of played music, echo signals of speaking sounds of a user or a conversation partner of the wireless noise reduction earphone during conversation, etc.) in the ear canal of the wearer. The feedback microphone 131 converts the picked-up noise into an analog electrical signal and transmits the analog telecommunication signal to the second analog-to-digital converter 133. Second analog-to-digital converter 133 converts the analog electrical signal to a digital signal and transmits the digital signal to feedback ANC filter 135. The feedback ANC filter 135 performs feedback noise reduction processing on the digital signal, and then outputs the audio signal subjected to the feedback noise reduction processing.

It will be appreciated that the feedback noise reduction channel 13 may further comprise a second low pass and down-sampling filter 134 connected between the second analog-to-digital converter 133 and the feedback ANC filter 135. The second analog-to-digital converter 133 transmits the digital signal to the second low-pass and downsample filter 134 after converting the analog electric signal into the digital signal. The second low-pass and down-sampling filter 134 filters and down-samples the digital signal, and then transmits the sampled digital signal to the feedforward ANC filter 135 for noise reduction. The second low-pass and downsample filter 134 can perform the same function as the first low-pass and downsample filter 114, and therefore, the description thereof is omitted here.

It is to be appreciated that the feedback noise reduction channel 13 may further include a second analog gain module 132 connected between the feedback microphone 131 and the second analog-to-digital converter 133. The feedback microphone 131 transmits the analog electric signal to the second analog gain module 132 after converting the collected noise into the analog electric signal. The second analog gain module 132 adjusts the analog electrical signal to increase the signal-to-noise ratio and increase the output power, and then transmits the adjusted analog electrical signal to the second analog-to-digital converter 133.

It will be appreciated that feedback noise reduction channel 13 may also include a limiter 136 connected between feedback ANC filter 135 and audio output module 15. This limiter 136 is used for carrying out amplitude limiting processing on the audio signal after being fed back and subjected to noise reduction processing by the feedback ANC filter 135, on the one hand, it is able to eliminate the too large interference signal in the audio signal after being fed back and subjected to noise reduction processing by the feedback ANC filter 135, on the other hand, it is able to avoid that the audio signal after being fed back and subjected to noise reduction processing by the feedback ANC filter 135 is output after being fed forward and subjected to noise reduction processing by the feedforward noise reduction channel 11, and when the audio signal to be played is output by the audio output module 15 after being subjected to data fusion or superposition, because the signal is too strong, the audio output module 15 is damaged, thereby generating noise, such as "snap" sound.

It will be appreciated that the noise reduction system 10 of the wireless noise reduction headset may also include an audio echo cancellation module 12. The audio echo cancellation module 12 taps into the feedback noise reduction channel 13 from a location between the second low pass and downsample filter 134 and the feedback ANC filter 135. The audio echo cancellation module 12 collects echo signals in the played audio signals when playing audio through the wireless noise reduction earphone, and is configured to cancel the echo signals in the feedback noise reduction channel 13 (corresponding to the echo signals of the sounds played by the speaker of the wireless noise reduction earphone collected by the feedback microphone 131), and cancel the influence of the played echo signals on the noise in the ear canal collected by the feedback noise reduction channel 13, that is, to implement echo cancellation, so that the audio signals played by the speaker of the wireless noise reduction earphone are not cancelled by the feedback noise reduction channel to remove part of the audio signals, especially the audio signals of the low frequency part. The signal output by the audio echo cancellation module 12 and the signal output by the second low-pass and down-sampling filter 134 are subjected to data fusion (the fusion process is to eliminate the influence of the played echo signal on the noise audio signal in the ear canal collected in the feedback noise reduction channel), and the fused signal is transmitted to the feedback ANC filter 135.

It will be appreciated that in other embodiments, either the feedforward noise reduction path 11 or the feedback noise reduction path 13 may be omitted, i.e., the noise reduction path of the noise reduction system 10 of the wireless noise reduction headset may be one of, but need not include both, the feedforward noise reduction path 11 and the feedback noise reduction path 13.

The audio output module 15 performs digital-to-analog conversion on the audio signal output after the noise reduction processing is fed forward through the feed-forward noise reduction channel 11, the audio signal output after the noise reduction processing is fed back through the feedback noise reduction channel 13, and the audio signal generated after the data fusion is performed on the audio signal to be played, and plays the audio signal after the noise reduction processing. It can be understood that, when debugging the noise reduction performance of the noise reduction system of the wireless noise reduction earphone, the audio output module 15 may perform digital-to-analog conversion on the audio signal generated after performing the data fusion on the audio signal output after performing the feedforward noise reduction processing on the feedforward noise reduction channel 11 and the audio signal output after performing the feedback noise reduction processing on the feedback noise reduction channel 13, and play the audio signal after performing the noise reduction processing.

It is understood that feedforward ANC filter 113, feedback ANC filter 133 and audio echo cancellation module 12 may all be adaptive filters or fixed filters. In addition, the feedforward ANC filter 113, the feedback ANC filter 133 and the audio echo cancellation module 12 may each have an FIR (finite impulse response filter) structure, an IIR (infinite impulse response filter) structure, or a filter structure in which both an FIR and an IIR are mixed.

Referring to fig. 2, an embodiment of the present application further provides a debugging system 20 for debugging noise reduction parameters of a wireless noise reduction earphone. For the noise reduction system 10 described above, the noise reduction parameter may be, for example, a performance parameter (e.g., phase, delay, etc.) of the feedforward ANC filter 113 or a gain loaded on the feedforward ANC filter 113, a performance parameter (e.g., phase, delay, etc.) of the feedback ANC filter 133 or a gain loaded on the feedback ANC filter 133, or a performance parameter (e.g., phase, delay, etc.) of the audio echo cancellation module 12 or a gain loaded on the audio echo cancellation module 12. In this embodiment, the debugging system 20 includes a test sound source 21, an audio detecting device 23 and a host 25. When the debugging system 20 debugs the noise reduction parameters of the wireless noise reduction earphone, the wireless noise reduction earphone is in a power-on state, and the noise reduction function is in an on state (this corresponds to a case that the wireless noise reduction earphone is provided with an option for a user to select whether to turn on the noise reduction function, for example, the wireless noise reduction earphone is provided with a button for the user to select whether to turn on the noise reduction function). It can be understood that, the wireless noise reduction earphone is not provided with an option for the user to select whether to turn on the noise reduction function, that is, the noise reduction function of the wireless noise reduction earphone is the inherent function of the wireless noise reduction earphone, and at this time, the debugging system 20 only needs to confirm that the wireless noise reduction earphone is in the on state when the noise reduction parameters of the wireless noise reduction earphone are continuously debugged.

The test audio source 21 is used to play test audio. The test audio may be, for example, a swept frequency signal. The frequency range of the frequency sweep signal may be, for example, between 10Hz and 20 KHz. Illustratively, the lower frequency of the frequency range of the frequency sweep signal may be 10Hz, 20Hz, or any frequency value therebetween, e.g., 13Hz, 15Hz, 17Hz, while the upper frequency of the frequency range of the frequency sweep signal may be 10KHz, 20KHz, or any frequency value therebetween, e.g., 10KHz, 15KHz, or 20 KHz. It is to be understood that the frequency ranges of the frequency sweep signals listed herein are merely examples and are not limiting. The test audio source 21 can be in signal connection with the host computer 25, and start/end playing the test audio and adjust the frequency range of the played test audio under the control of the host computer 25. Alternatively, the test sound source 21 may be independently set, and start/stop of playing the test audio and adjustment of the frequency range of the played test audio are manually controlled. The test audio source may comprise one loudspeaker, or a plurality of loudspeakers. When the test sound source includes a plurality of speakers, each speaker may be placed around the wireless noise reduction earphone.

The audio detection device 23 is disposed near the wireless noise reduction earphone, and is configured to detect an audio signal output by the wireless noise reduction earphone after performing noise reduction processing on the test audio, and feed back a detection result to the host computer 25. The audio detection device 23 may be, for example, an artificial ear, and a microphone is disposed in the ear, and may collect a sound signal and be connected to the host computer 25 through an audio line. For the wireless noise reduction earphone with the noise reduction system 10, the audio signal output by the wireless noise reduction earphone after performing noise reduction processing on the test audio is the audio signal which is acquired by the feedforward noise reduction path 11, subjected to noise reduction processing on the test audio, acquired by the output audio signal and the feedback noise reduction path 13, subjected to noise reduction processing on the test audio, subjected to data fusion and played after being processed by the audio output module 15.

The host 25 and the audio detection device 23 may be connected by wire or wirelessly. In this embodiment, the host 25 and the audio detection device 23 are connected by an audio line. The host 25 is wirelessly connected to the wireless noise reduction earphone. The host 25 and the audio detection device 23 may be connected, for example, by an audio line. The host 25 and the wireless noise reduction headset may be connected, for example, by BT (Bluetooth) or BLE (Bluetooth low energy). Further, the host 25 and the wireless noise reduction earphone can communicate with each other through a predetermined frequency point, for example, a certain frequency point on the bluetooth frequency point from 2.402GHz to 2.480 GHz. The predetermined frequency point may be, for example, 2.402GHz, 2.405GHz, 2.432GHz, 2.480GHz, or some frequency point therebetween. The host 25 and the wireless noise reduction earphone communicate through a preset frequency point, so that the BT or BLE pairing time can be reduced, and the test time can be shortened.

The host computer 25 is configured to adjust the noise reduction parameters of the wireless noise reduction earphone when it is determined that the noise reduction parameters need to be adjusted based on the detection result received from the audio detection device 23, and wirelessly transmit the adjusted noise reduction parameters to the wireless noise reduction earphone for configuration.

Or, the host 25 is configured to display the detection result and receive the adjusted noise reduction parameter entered by the user based on the detection result after receiving the detection result fed back by the audio detection device 23, and wirelessly transmit the adjusted noise reduction parameter to the wireless noise reduction earphone for configuration. In one embodiment, the host 25 may display the detection result received from the audio detection device 23 through a display device connected thereto. The user can input the adjusted noise reduction parameters through the input device connected to the host computer 25 according to the display contents and his or her own experience. After receiving the adjusted noise reduction parameters input by the user, the host computer 25 wirelessly transmits the adjusted noise reduction parameters to the wireless noise reduction earphone for configuration. In another embodiment, the host 25 itself includes a display module and an input module, and the host 25 displays the detection result through the display module after receiving the detection result fed back by the audio detection device 23, receives the adjusted noise reduction parameter input by the user through the input module according to the display content, and then wirelessly transmits the adjusted noise reduction parameter to the wireless noise reduction earphone for configuration. It is understood that, in other embodiments, the user may also input the noise reduction parameter adjustment amount through the input device or the input module, and after receiving the noise reduction parameter adjustment amount, the host 25 may calculate the adjusted noise reduction parameter according to the noise reduction parameter adjustment amount and the current noise reduction parameter of the wireless noise reduction earphone determined according to the detection result. Of course, the above-listed contents are merely examples, and the present application is not limited thereto.

It can be understood that, when determining that the noise reduction parameters of the wireless noise reduction earphone need to be adjusted based on the detection result fed back by the audio detection device, the host 25 may adjust the noise reduction parameters to generate the noise reduction parameter group. The set of noise reduction parameters comprises a plurality of adjusted noise reduction parameters. The host computer 25 sequentially wirelessly transmits the adjusted noise reduction parameters in the noise reduction parameter group to the wireless noise reduction earphone for configuration. And the wireless noise reduction earphone carries out noise reduction processing on the test audio after completing configuration according to the adjusted noise reduction parameters every time, and outputs an audio signal. The audio detection device 23 detects audio signals output by the wireless noise reduction earphone after being configured with different noise reduction parameters, and feeds back detection results of each time to the host computer 25. The host 25 determines a target noise reduction parameter in the noise reduction parameter set according to a detection result of an audio signal output by performing noise reduction processing on the test audio after the wireless noise reduction earphone completes configuration each time, which is fed back by the audio detection device 23, and wirelessly transmits the target noise reduction parameter to the wireless noise reduction earphone for configuration. The target noise reduction parameters are noise reduction parameters which can obtain the optimal noise reduction performance after the wireless noise reduction earphone in the noise reduction parameter group is configured. The host computer 25 may determine the target noise reduction parameter by comparing the detection result fed back by the audio detection device 23 for each audio signal output by the wireless noise reduction headphone after the configuration is completed.

It is to be appreciated that the wireless noise reducing headsets may include a left wireless noise reducing headset and a right wireless noise reducing headset with different serial numbers. Both the left wireless noise reduction earphone and the right wireless noise reduction earphone have the noise reduction system 10. The host 25 is wirelessly connected with the left wireless noise reduction earphone and the right wireless noise reduction earphone through BLE. The audio detection device 23 includes a left audio detection device and a right audio detection device. The left audio detection device and the right audio detection device are connected to the host computer 25 through a left audio line and a right audio line, respectively. The left side audio frequency detection device and the right side audio frequency detection device respectively correspond to the left side wireless noise reduction earphone and the right side wireless noise reduction earphone and are close to the corresponding wireless noise reduction earphone. The audio signal output after the noise reduction processing is performed on the test audio by the left wireless noise reduction earphone detected by the left audio detection device and the audio signal output after the noise reduction processing is performed on the test audio by the right wireless noise reduction earphone detected by the right audio detection device are respectively fed back to the host computer 25 in the form of a left channel audio signal and a right channel audio signal. The host 25 determines the noise reduction parameters of the left wireless noise reduction earphone and the right wireless noise reduction earphone according to the detection results fed back by the left audio detection device and the right audio detection device, generates corresponding configuration information according to the noise reduction parameters and the serial numbers of the left wireless noise reduction earphone and the right wireless noise reduction earphone, and broadcasts the configuration information to the left wireless noise reduction earphone and the right wireless noise reduction earphone. The method for determining the noise reduction parameters of the left wireless noise reduction earphone and the right wireless noise reduction earphone respectively by the host 25 according to the detection results fed back by the left audio detection device and the right audio detection device may adopt the above-mentioned method for determining the noise reduction parameters, and is not described herein again. And when the serial number in the configuration information is determined to be consistent with the self serial number, the left wireless noise reduction earphone and the right wireless noise reduction earphone are configured according to the configuration information.

It can be understood that the serial numbers of the left wireless noise reduction earphone and the right wireless noise reduction earphone can be the respective bluetooth MAC addresses, so that the host 25 can respectively obtain the serial numbers of the left wireless noise reduction earphone and the right wireless noise reduction earphone when wirelessly connecting with the left wireless noise reduction earphone and the right wireless noise reduction earphone; alternatively, the serial numbers of the left wireless noise reduction earphone and the right wireless noise reduction earphone may be identifiers that the host configures for the left wireless noise reduction earphone and the right wireless noise reduction earphone to distinguish the left wireless noise reduction earphone and the right wireless noise reduction earphone. The identifier of the left wireless noise reducing headphone may for example be odd, while the identifier of the right wireless noise reducing headphone may for example be even; or the identifier of the left wireless noise reduction earphone is an English letter L, and the identifier of the right wireless noise reduction earphone is an English letter R. Of course, the above is merely an example, and the identifiers assigned to the left wireless noise reduction earphone and the right wireless noise reduction earphone by the host 25 are not limited thereto. In addition, the serial numbers of the left wireless noise reduction earphone and the right wireless noise reduction earphone can be identification codes which are respectively possessed by the left wireless noise reduction earphone and the right wireless noise reduction earphone and used for distinguishing the left earphone from the right earphone. The identification code may be, for example, an identification code that the manufacturer of the wireless noise reduction headset configures for the left and right earphones, respectively, in order to be able to distinguish between them. This identification code is foreseen by the host 25, i.e. before commissioning starts, the identification code may be entered manually into the host 25, so that the host 25 can generate corresponding noise reduction parameters for configuring the left and right wireless noise reduction headsets according to the left and right channel audio signals fed back by the audio detection device 23 in combination with the identification code.

It is understood that in other embodiments, the host 25 may be wirelessly connected to one of the left wireless noise reducing headset and the right wireless noise reducing headset, and the wireless noise reducing headset that is not wirelessly connected to the host 25 knows the bluetooth MAC address of the other wireless noise reducing headset in advance. Since the wireless noise reduction earphone not wirelessly connected with the host 25 knows the bluetooth MAC address of another wireless noise reduction earphone in advance, the wireless noise reduction earphone not wirelessly connected with the host 25 can be connected with another wireless noise reduction earphone through a bluetooth signal. The wireless noise reduction earphone not wirelessly connected to the host 25 may know the bluetooth MAC address of another wireless noise reduction earphone in advance by manually writing in at the time of factory shipment. Illustratively, the host 25 is wirelessly connected to the left wireless noise reducing headset, and the bluetooth MAC address of the left wireless noise reducing headset is known in advance by the right wireless noise reducing headset. Because the right wireless noise reduction earphone knows the Bluetooth MAC address of the left wireless noise reduction earphone in advance, the right wireless noise reduction earphone can be connected with the left wireless noise reduction earphone through Bluetooth signals. For example, the bluetooth MAC address of the left wireless noise reduction earphone may be written into the right wireless noise reduction earphone together with the bluetooth MAC address of the right wireless noise reduction earphone when the manufacturer configures the bluetooth MAC address for the right wireless noise reduction earphone. In this case, the host 25 determines the noise reduction parameters of the left wireless noise reduction earphone and the right wireless noise reduction earphone according to the detection results fed back by the left audio detection device and the right audio detection device, respectively, generates corresponding configuration information according to the noise reduction parameters and the serial numbers of the left wireless noise reduction earphone and the right wireless noise reduction earphone, and broadcasts the configuration information to the left wireless noise reduction earphone through BLE. And when the serial number in the configuration information is determined to be inconsistent with the self serial number, the configuration information is transmitted to the right wireless noise reduction earphone for configuration in a Bluetooth mode. The host 25 may determine whether the previous configuration of the noise reduction parameters of the left and right wireless noise reduction earphones is successful according to the detection result subsequently fed back by the audio detection device. This way, the connection between the host and the wireless noise reduction earphone can be simplified.

According to the method and the device, the host of the debugging system is wirelessly connected with the wireless noise reduction earphone to transmit the noise reduction parameters, so that the debugging and the configuration of the noise reduction parameters can be carried out after the earphone is assembled, the problem that the wireless noise reduction earphone does not have a wired connection interface and is not beneficial to carrying out noise reduction performance debugging in the prior art can be avoided, the noise reduction parameters obtained by carrying out noise reduction performance debugging on the wireless noise reduction earphone before the wireless noise reduction earphone is assembled can be avoided, and the problem that the noise reduction parameters are inapplicable due to the change of characteristics such as a sound cavity after the wireless noise reduction earphone is assembled can be solved.

The host and the wireless noise reduction earphone can be conveniently and rapidly connected by adopting BT or BLE, and the wireless noise reduction earphone does not need to be additionally provided with other wireless communication modules. The host machine and the wireless noise reduction earphone are communicated through the preset frequency points, so that the pairing and connection time of wireless connection can be reduced, and the debugging time is further saved.

The left wireless noise reduction earphone and the right wireless noise reduction earphone are distinguished through serial numbers, the host machine distinguishes detection results of audio signals output by the left wireless noise reduction earphone and the right wireless noise reduction earphone fed back by the left and right audio detection equipment through left and right audio signals, and the noise reduction parameters and the serial number respectively generate configuration information corresponding to the left wireless noise reduction earphone and the right wireless noise reduction earphone, and wirelessly transmitting the configuration information to the left wireless noise reduction earphone and the right wireless noise reduction earphone, when the serial number in the configuration information is determined to be consistent with the self serial number, the configuration is carried out according to the configuration information, so that the noise reduction performance of the left wireless noise reduction earphone and the noise reduction performance of the right wireless noise reduction earphone can be debugged simultaneously, and the debugging time can be further saved.

When the host determines that the noise reduction parameters of the wireless noise reduction earphone need to be adjusted based on the detection result, the host adjusts the noise reduction parameters to generate a noise reduction parameter group comprising a plurality of adjusted noise reduction parameters, and wirelessly transmits the adjusted noise reduction parameters in the noise reduction parameter group to the wireless noise reduction earphone in sequence for configuration, so that a target noise reduction parameter capable of obtaining optimal noise reduction performance is determined from the noise reduction parameter group based on the test result of each group of noise reduction parameters, and the target noise reduction parameter is transmitted to the wireless noise reduction earphone for configuration.
