Detailed Description
The following description of the exemplary embodiments of the present application, taken in conjunction with the accompanying drawings, includes various details of the embodiments of the application to assist in understanding, which are to be considered exemplary only. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the present application. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.
Fig. 1A is a block diagram of a wireless headset according to an embodiment of the present application. In consideration of various environmental noises when a user uses the wireless headset in an actual scene, and the condition that the quality of transmitted audio is seriously affected once the noise reduction microphone fails, the embodiment provides the wireless headset which can monitor the working state of the noise reduction microphone in real time. Optionally, the wireless headset in this embodiment may be a true wireless bluetooth headset. Further, the wireless headset in this embodiment may be a single headset or may be dual (i.e. including a left headset and a right headset); it should be noted that, in the case that the wireless earphones are two, each wireless earphone has the structure and the function of the wireless earphone provided by the present embodiment. As shown in fig. 1, the wireless headset 100 may specifically include: a storage unit 101, a sound production unit 102, a noise reduction microphone 103, and a processor 104.
The storage unit 101 is a memory inside the wireless headset 100, and reference signal data is stored therein. The reference signal data is used for generating the audio signal, and may specifically include playback parameters, such as frequency, amplitude, etc., necessary for generating the audio signal.
The sound emitting unit 102 may be constituted by a device having a function of playing an audio signal, such as a speaker. Alternatively, the sound generating unit 102 is connected to the storage unit 101, and may acquire the reference signal data from the storage unit 101 according to a set time period and play the audio signal based on the reference signal data. Specifically, the sound generation unit 102 generates an audio signal according to the reference signal data and plays the audio signal.
Exemplarily, in order to realize real-time monitoring of the working state of the noise reduction microphone under the condition that a user does not sense the noise reduction microphone, in this embodiment, the reference signal data is high-frequency signal data; wherein the frequency of the reference signal data is greater than the maximum tolerable frequency of the user, such as 21 kHz. The audio signal played by the sound generating unit 102 based on the reference signal data is substantially a high frequency signal. Further, in order to reduce the complexity of the calculation, the frequency of the reference signal data in this embodiment is preferably a single frequency.
Alternatively, the wireless headset 100 in the present embodiment may have one or two sound emitting units. With one sound emitting unit, the sound emitting unit can be used not only to play audio signals determined based on the reference signal data, but also to play audio contents such as songs and the like in a scene where the user uses the wireless headset. Furthermore, in the case of having one sound generating unit, in order not to affect the normal use of the user, the sound generating unit may play the audio signal at the gap between two pieces of audio content played by the wireless earphone for the user. For example, a first song is played followed by an audio signal determined based on the reference signal data, and a second song is played thereafter.
To further enhance the user experience, as an alternative to the embodiment of the present application, the wireless headset 100 in the present embodiment may have two sound emitting units, including the sound emitting unit 102 dedicated to playing the audio signal determined based on the reference signal data, and the sound emitting unit dedicated to playing the audio content in the scene where the user uses the wireless headset (not shown in fig. 1A).
In this embodiment, the noise reduction microphone 103 may be configured to collect an audio signal played by the sound generating unit 102, and perform noise reduction processing on the collected audio signal to obtain a noise-reduced audio signal; optionally, the noise reduction microphone 103 is connected to the processor 104, and may send the noise-reduced audio signal to the processor 104, and then the processor 104 may determine the working state of the noise reduction microphone 103 according to the state detection rule associated with the reference signal data and the noise-reduced audio signal. The processor is a processing chip of the wireless headset 100. In this embodiment, the working state of the noise reduction microphone may be a normal working state or an abnormal working state; the state detection rule may be a condition that needs to be satisfied when the noise reduction microphone is in a normal operating state, which is set in advance based on the reference signal data; alternatively, the state detection rule may also be stored in the storage unit 102, and further, the state detection rule may be stored in the storage unit 102 in association with the reference signal data. Further, the processor 104 may process the noise-reduced audio signal, may obtain the state detection rule associated with the reference signal data from the storage unit 102, and may compare the obtained state detection rule with result data obtained by processing the noise-reduced audio signal to determine the operating state of the noise-reduction microphone 103.
Further, the noise reduction microphone 103 may also be used to collect audio content in a wireless headset scene used by a user, such as human voice in a call scene. Alternatively, in a scenario where the user uses the wireless headset, if the noise reduction microphone 103 is in the process of acquiring the audio signal and the user is using the wireless headset (e.g., in transit), the noise reduction microphone 103 may substantially acquire a mixed signal including the audio signal and the audio content, such as the voice in a conversation scenario. The noise reduction microphone may perform noise reduction processing on the mixed signal, and further, the processor 104 may adopt a signal separation technique to separate the noise-reduced mixed signal transmitted by the noise reduction microphone 103, and extract a noise-reduced audio signal therefrom; the operating state of the noise reduction microphone 103 is then determined based on the state detection rules associated with the reference signal data and the noise reduced audio signal.
Optionally, the wireless headset in this embodiment may further include a main microphone (not shown in fig. 1A), where the main microphone is specifically used for collecting audio content in a scenario where the user uses the wireless headset, such as human voice in a conversation scenario; since the actual environment of the user is complex and the human voice may include ambient noise, the noise reduction microphone 103 is used for noise reduction. Optionally, in this embodiment, the audio content collected by the noise reduction microphone 103 may be transmitted by the main microphone.
Specifically, the working principle of the wireless headset in this embodiment for realizing real-time monitoring of the working state of the noise reduction microphone is as follows: after determining that the wireless headset 100 establishes a communication connection with an intelligent terminal such as a mobile phone, the sound generating unit 102 acquires reference signal data from the storage unit 101 at set time intervals, and plays an audio signal based on the reference signal data; the noise reduction microphone 103 collects the audio signal played by the sound production unit 102, performs noise reduction processing on the collected audio signal, and then transmits the noise-reduced audio signal to the processor 104; the processor 104 processes the noise-reduced audio signal, and compares the state detection rule with the result data obtained by processing the noise-reduced audio signal to determine the operating state of the noise-reduced microphone 103. In the case that the wireless headset 100 is a true wireless bluetooth headset, the wireless headset 100 establishes a communication connection with an intelligent terminal, such as a mobile phone, where the wireless headset establishes a communication connection with a bluetooth module in the intelligent terminal through the bluetooth module therein.
According to the technical scheme, the sound production unit used for playing the audio signal based on the reference signal data built in the storage unit of the wireless earphone is introduced, the sound production unit, the noise reduction microphone and the processor are matched with one another, and based on the state detection rule, the working state of the noise reduction microphone can be monitored in real time. The problem of the prior art can't monitor the microphone operating condition that makes an uproar is solved, for avoiding making an uproar the microphone that makes an uproar to appear breaking down and lead to transmitting the phenomenon that the audio quality is relatively poor establishes, for can real-time supervision make an uproar the microphone operating condition provides a new thinking that makes an uproar.
In a song playing scene, because the intelligent terminal may carry transmission noise in the process of transmitting a song to the wireless headset, the main microphone in the wireless headset can collect the environmental noise of the user, and then in order to ensure the quality of the played song, the noise reduction microphone is required to perform noise reduction processing. For another example, in a call scenario, a main microphone in the wireless headset collects voice and environmental noise of a user, and then a noise reduction microphone is also required to perform noise reduction processing to ensure call voice quality.
Furthermore, in order to improve user experience, under the condition that it is determined that the noise reduction microphone is in an abnormal working state, the processor 104 starts an active noise reduction model built in the wireless headset, performs noise reduction processing on audio content acquired by the main microphone, such as voice in a call scene, by the active noise reduction model, and transmits the voice after the noise reduction processing to the beneficiary, where the beneficiary is the user of the other party. It is worth noting that under the condition that the noise reduction microphone is monitored to be in fault, the active noise reduction model is adopted to reduce noise, output sound can be guaranteed to achieve the noise reduction effect, and user experience is greatly improved.
On the basis of the above embodiments, as an optional manner of the embodiments of the present application, the noise reduction microphone 103 and the sound generating unit 102 in the present embodiment are in the same coupling cavity, and the axial center of the sound generating unit 102 and the sound hole of the noise reduction microphone 103 are in the same axial line, as shown in fig. 1B. It should be noted that, in the present embodiment, by setting the noise reduction microphone 103 and the sound generating unit 102 in the above manner, it can be ensured that a large part of the audio signal played by the sound generating unit 102 can be collected by the noise reduction microphone 103, that is, the audio signal leakage is reduced, and a foundation is laid for ensuring that the working state of the noise reduction microphone is accurately identified.
Furthermore, the main microphone and the noise reduction microphone 103 in this embodiment are not in the same coupling cavity, and the sounding unit dedicated to playing the audio content in the scenario where the user uses the wireless headset and the sounding unit 102 dedicated to playing the audio signal determined based on the reference signal data are not in the same coupling cavity, so that it is ensured that the process of testing the working state of the noise reduction microphone 103 does not affect the normal use of the wireless headset by the user.
For example, on the basis of the foregoing embodiment, as an optional manner of the embodiment of the present application, the processor 104 may upload the noise-reduced audio signal transmitted by the noise-reduction microphone to the server, and the server determines the operating state of the noise-reduction microphone 103 according to the state detection rule associated with the reference signal data and the noise-reduced audio signal. Optionally, the server is preset with a corresponding signal processing algorithm, and may perform signal processing on the noise-reduced audio signal to obtain a signal parameter; then, the server may determine the operating state of the noise reduction microphone 103 based on a state detection rule associated with pre-stored reference signal data and a signal parameter obtained by performing signal processing on the noise-reduced audio signal. Specifically, the uploading of the noise-reduced audio signal to the server by the processor 104 may be that the processor 104 cooperates with a communication module (not shown in fig. 1A) in the wireless headset 100, such as a bluetooth module, to transmit the noise-reduced audio signal to a client in the intelligent terminal, and then the audio signal is transmitted to the server by the client.
It can be understood that, since the wireless headset 100 directly transmits the noise-reduced audio signal to the server, a certain bandwidth is occupied, and the use of the user is affected. Therefore, in consideration of bandwidth occupation and power consumption of the wireless headset, the present embodiment preferably monitors the operating state of the noise reduction microphone 103 using the wireless headset local processor 104. For example, the processor 104 may perform signal processing on the noise-reduced audio signal to obtain signal parameters; the operating state of the noise reduction microphone 103 is then determined based on the state detection rules and signal parameters associated with the reference signal data. Signal parameters may include, but are not limited to, amplitude, frequency, distortion, and the like; correspondingly, the state detection rule may include, but is not limited to, the conditions that the amplitude, frequency, distortion and the like need to be satisfied when the noise reduction microphone is in a normal operating state.
Specifically, the processor 104 may perform fourier transform on the noise-reduced audio signal to obtain a frequency domain signal corresponding to the noise-reduced audio signal; analyzing the frequency signal to obtain parameters such as amplitude, frequency and distortion of the noise-reduced audio signal; thereafter, it may be determined whether parameters such as the amplitude, frequency, and distortion of the noise-reduced audio signal satisfy the state detection rule, for example, whether the amplitude of the noise-reduced audio signal is within the amplitude range set in the state detection rule, to determine the operating state of the noise reduction microphone 103. The present embodiment provides an alternative way of determining the operational state of a noise reduction microphone.
Alternatively, after determining the operating state of the noise reduction microphone 103, the processor 104 may upload the determined operating state of the noise reduction microphone 103 to the server. Specifically, the processor 104 cooperates with a communication module, such as a bluetooth module, in the wireless headset 100 to transmit the determined working state of the noise reduction microphone 103 to a client in the smart terminal, and then the working state is transmitted from the client to the server. It should be noted that, by adding the operation of uploading the working state of the noise reduction microphone to the server, the purpose is to facilitate the server to perform state statistical analysis, and once the noise reduction microphone fails, even if a large amount of returned goods are returned to the factory, the return of the returned goods is not required to be performed with human labor for re-detection.
Fig. 2 is a flowchart of an operating condition monitoring method according to an embodiment of the present application. The embodiment of the application is suitable for the situation of monitoring the working state of the noise reduction microphone in the wireless earphone (such as a true wireless Bluetooth earphone). This embodiment may be performed by an operation status monitoring device, which may be implemented in software and/or hardware, and may be integrated in the wireless headset, in particular in a processor in the wireless headset. As shown in fig. 2, the method includes:
s201, acquiring a noise-reduced audio signal transmitted by a noise-reduction microphone in the wireless earphone; the audio signal after noise reduction is obtained by carrying out noise reduction processing on the collected audio signal played by the sound production unit in the wireless earphone by the noise reduction microphone; the audio signal played by the sound emitting unit is determined based on the reference signal data built in the storage unit of the wireless headset.
As an optional mode of the embodiment of the present application, the noise reduction microphone and the sound generating unit are located in the same coupling cavity of the wireless headset, and an axis of the sound generating unit and a sound hole of the noise reduction microphone are located on the same axis. The method can ensure that most of the audio signals played by the sound production unit can be collected by the noise reduction microphone, namely, the audio signals are reduced from leaking, and a foundation is laid for ensuring the accurate identification of the working state of the noise reduction microphone.
Exemplarily, in order to realize real-time monitoring of the working state of the noise reduction microphone under the condition that a user does not sense the noise reduction microphone, in this embodiment, the reference signal data is high-frequency signal data; wherein the frequency of the reference signal data is greater than the maximum tolerable frequency of the user, such as 21 kHz. And the audio signal played by the sound production unit based on the reference signal data is a high-frequency signal substantially. Further, in order to reduce the complexity of the calculation, the frequency of the reference signal data in this embodiment is preferably a single frequency.
S202, determining the working state of the noise reduction microphone according to the state detection rule associated with the reference signal data and the noise-reduced audio signal.
As an optional manner of the embodiment of the present application, determining the working state of the noise reduction microphone according to the state detection rule associated with the reference signal data and the noise-reduced audio signal may specifically be performing signal processing on the noise-reduced audio signal to obtain a signal parameter; the operating state of the noise reduction microphone is determined based on the state detection rules and the signal parameters associated with the reference signal data.
For example, after the working state of the noise reduction microphone is determined, the working state of the noise reduction microphone can be uploaded to the server, so that the server can perform state statistical analysis, and once the noise reduction microphone fails, even if a large amount of returned goods are returned to a factory, the noise reduction microphone does not need to be input to perform re-detection.
Further, for improving user experience, under the condition that it is determined that the noise reduction microphone is in an abnormal working state, an active noise reduction model built in the wireless headset can be adopted, noise reduction processing is performed on audio content collected by the main microphone, such as voice in a conversation scene, through the active noise reduction model, the voice after the noise reduction processing is transmitted to a beneficiary party, and the beneficiary party is an opposite party user at the moment. It is worth noting that under the condition that the noise reduction microphone is monitored to be in fault, the active noise reduction model is adopted to reduce noise, so that the output sound can be guaranteed to achieve the noise reduction effect, and the user experience is greatly improved.
It should be noted that, for a specific implementation process of the working state monitoring method provided in this embodiment, reference may be made to the specific content of the wireless headset in the foregoing embodiment, and details are not described here again.
