Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, fig. 1 is a flowchart illustrating a whisper amplifying method according to an embodiment of the present invention. The method can comprise the following steps:
step 101: and acquiring a first whisper amplifying instruction.
The first whisper amplifying instruction in this step may be an instruction for controlling a processor in the earphone to amplify the audio signal to be played by the speaker after the first amplification, for the second time. Specifically, the specific type and content of the first whisper amplification instruction in this step may be set by a designer according to a practical scene and a user requirement, and if only the audio signal with relatively small sound needs to be amplified for the second time, so that the sound played by the speaker is increased, the type of the first whisper amplification instruction may be an increase sound instruction, that is, the secondary amplification factor of the audio signal corresponding to the increase sound instruction for the second amplification is greater than 1; the type of the first whisper amplification instruction may also be an increase sound instruction corresponding to different amplification factors, that is, each increase sound instruction may correspond to a different secondary amplification factor, and the corresponding secondary amplification factors are greater than 1. If the audio signal with smaller sound needs to be amplified for the second time to increase the sound played by the speaker, the audio signal with smaller sound needs to be amplified for the second time to decrease the sound played by the speaker, the type of the first whisper amplification instruction may further include a decrease sound instruction, or an increase sound instruction and a decrease sound instruction corresponding to different amplification factors, that is, each decrease sound instruction may correspond to a different secondary amplification factor, and the corresponding secondary amplification factor is smaller than 1. The present embodiment does not set any limit to this.
It can be understood that the purpose of this step may be to determine that the once amplified audio signal to be played by the speaker needs to be amplified for the second time by the processor in the headset by obtaining the first whispering instruction. Specifically, the specific mode of obtaining the first whisper amplification instruction in this step may be set by a designer or a user, and if the specific mode is determined according to the audio signal to be played by the speaker after one amplification and the corresponding threshold, the corresponding first whisper amplification instruction is automatically generated, whether the audio signal needs to be amplified for the second time is intelligently identified, for example, when the first whisper amplification instruction only includes an increase sound instruction, whether the obtained audio signal is lower than the threshold may be determined, and if so, the first whisper amplification instruction is generated. The processor may also generate a first whisper amplification instruction according to a control instruction sent by a terminal connected to the earphone, or directly receive the first whisper amplification instruction sent by the terminal connected to the earphone, for example, when the earphone is a wireless earphone, a user may control a mobile phone (terminal) connected in pairing with the wireless earphone to send a volume adjustment instruction to the wireless earphone, the processor of the wireless earphone may generate a sound increase instruction (first whisper amplification instruction) when the current volume is the maximum volume and receives a volume increase instruction (volume adjustment instruction), and generate a sound decrease instruction (first whisper amplification instruction) when the current volume is the minimum volume and receives a volume decrease instruction (volume adjustment instruction); the user can also control to generate a corresponding first whisper amplification instruction in the APP of the mobile phone and send the first whisper amplification instruction to the wireless headset. The processor can also generate a first whisper amplification instruction according to data acquired by the human-computer interaction device in the earphone, for example, when the earphone is a wireless earphone, the processor can generate a corresponding first whisper amplification instruction by comparing data acquired by an acceleration sensor in the wireless earphone with preset gesture data, so as to realize gesture control of a user; or generating a first whisper amplifying instruction by using a volume adjusting instruction corresponding to a volume key or a signal of a touch key in the earphone. The embodiment does not limit the first whisper amplifying instruction as long as the processor can obtain the first whisper amplifying instruction
It should be noted that, because the earphone wearer (user) often only needs to amplify the speech spoken by the opposite end in a special scene for the second time in the call process, before this step, it may also be determined whether the earphone is in a speech call state; if yes, entering the step; if not, the audio signal after one-time amplification is played by using a loudspeaker. Correspondingly, the step of judging whether the whisper amplification function is started or not can be included before the step, that is, when the user does not start the whisper amplification function, the audio signal after once amplification can be directly played by using the loudspeaker as in the prior art, and after the user starts the whisper amplification function, the step can be entered to obtain the first whisper amplification instruction. If the user controls the wireless earphone to start the whisper amplifying function through the APP in the mobile phone connected with the wireless earphone in a matching mode.
Specifically, for the case that the first whisper amplification instruction is not obtained corresponding to this step, the audio signal after one amplification may be directly played by using a speaker as in the prior art.
Step 102: and according to the first whisper amplification instruction, secondarily amplifying the audio signal to be played by the loudspeaker in the earphone after the primary amplification so as to play the audio signal after the secondary amplification by using the loudspeaker.
The purpose of this step may be that the processor in the earphone performs secondary amplification on the audio signal to be played by the speaker after the primary amplification (for example, the audio signal input to the speaker to be played in the prior art) according to the obtained first whisper amplification instruction, so that the speaker plays the audio signal after the secondary amplification, thereby ensuring that the sound heard by the earphone wearer can be normal volume, and ensuring the user communication quality.
Specifically, the specific manner in which the processor performs secondary amplification on the audio signal to be played by the speaker in the earphone after primary amplification according to the first whisper amplification instruction in this step may be set by a designer according to a practical scene and a user requirement, and if only one power amplifier device (such as an amplifier in the prior art) corresponding to the speaker is provided in the earphone, the processor in this step may receive the audio signal output by the power amplifier device after primary amplification, input the audio signal to the power amplifier device again for secondary amplification, and adjust the amplification factor of the power amplifier device according to the specific type of the first whisper amplification instruction, receive the audio signal output by the power amplifier device after secondary amplification, and send the audio signal to the speaker for playing, that is, one power amplifier device is used to perform secondary amplification on the audio signal; when the earphone is provided with other power amplifier devices (secondary power amplifier devices) corresponding to the loudspeaker in addition to the power amplifier devices (primary power amplifier devices), if the amplification factor of the secondary power amplifier devices can be adjusted, the processor in the step can input the audio signals output by the primary power amplifier devices after primary amplification into the secondary power amplifier devices according to the type of the first whisper amplification instruction, and correspondingly adjust the amplification factor of the secondary power amplifier devices, so that the secondary power amplifier devices input the audio signals after secondary amplification into the loudspeaker; if the amplification factor of the secondary power amplifier is fixed, the processor in this step may input the audio signal output by the primary power amplifier after the primary amplification to the corresponding secondary power amplifier according to the type of the first whisper amplification instruction, so that the corresponding secondary power amplifier inputs the audio signal after the secondary amplification to the speaker. The present embodiment does not set any limit to this.
It can be understood that, in order to reduce the cost, in this step, the processor may input the audio signal output by the first-stage power amplifier device after the first whisper amplification instruction is received, to the second-stage power amplifier device, so that the second-stage power amplifier device inputs the audio signal after the second amplification to the speaker, and the amplification factor of the second-stage power amplifier device is a fixed value greater than 1. When the sound of the opposite end of the call is small, the sound played by the loudspeaker is increased through the secondary power amplifier. That is to say, the above-mentioned second-stage power amplifier device is different from the original power amplifier device (first-stage power amplifier device) of the earphone in the prior art, and only receives the audio signal transmitted by the processor (such as the whisper recognition chip), and the volume after its amplification can be larger than the maximum volume of the first-stage power amplifier device in principle.
In the embodiment of the invention, the audio signal to be played by the speaker in the earphone after the primary amplification is performed is amplified for the second time according to the first whisper amplification instruction, so that the audio signal after the secondary amplification is played by the speaker, and the earphone wearer can hear the audio signal after the secondary amplification played by the speaker, so that the earphone can raise or reduce the volume of the sound played by the speaker for the second time under a special scene, thereby realizing the whisper amplification function under the special scene, ensuring the conversation quality of the normal volume conversation of the earphone wearer under the special scene, and improving the user experience.
Referring to fig. 2, fig. 2 is a flowchart illustrating another whisper amplifying method according to an embodiment of the present invention. The method can comprise the following steps:
step 201: and acquiring the audio signal to be played by a loudspeaker in the earphone after one amplification.
The audio signal in this step may be an audio signal received by a speaker in the wireless headset in the prior art and amplified by a power amplifier device (primary power amplifier device) such as an amplifier. For the specific mode of the processor obtaining the audio signal in this step, the specific mode can be set by the designer, if the processor and the secondary power amplifier in this step are set between the input end of the primary power amplifier and the input end of the speaker, as shown in fig. 3, the processor (whisper identification chip) can directly receive the audio signal (analog signal) output by the primary power amplifier, that is, the audio signal (digital signal) of the digital signal received and decoded by the wireless device in the wireless earphone from the corresponding terminal is converted into the audio signal (analog signal) through the digital-to-analog converter, and then transmitted to the primary power amplifier for primary amplification, so that the processor receives the audio signal after primary amplification.
Step 202: judging whether the audio signal is lower than a threshold value; if yes, go to step 203.
It can be understood that, this embodiment is shown by taking the example of using a secondary power amplifier device in the earphone to increase the sound played by the speaker, so that the purpose of this step may be to determine whether to perform secondary amplification on the audio signal by determining whether the audio signal after primary amplification is lower than a threshold value, thereby increasing the sound played by the speaker. Specifically, the setting of the threshold in this step may be set by a designer or a user, for example, the user may input a soft-sounding audio at one end by user-definition, and identify a value corresponding to the audio as the threshold by using an APP in a mobile phone (terminal) connected to the headset. The present embodiment does not set any limit to this.
It should be noted that, for the specific manner of determining whether the audio signal is lower than the threshold in this step, the designer may set the manner by himself, for example, in order to avoid activating or closing the secondary amplification of the audio signal every moment, this step may determine whether the audio signals in the preset time period are all lower than the threshold or most of the audio signals in the preset time period are lower than the threshold, that is, identify whisper (audio signal) in a period of time and may correspondingly activate the secondary amplification of the audio signal in this time period, so as to filter the interference of sudden increase of sound at a certain moment, and maintain the harmony of sound. The present embodiment does not set any limit to this.
Correspondingly, for the condition that the audio signal is not lower than the threshold in this step, the processor may play the audio signal after the primary amplification by using the speaker, as shown in fig. 3, when the processor is disposed between the speaker and the primary power amplifier device, the processor may directly send the acquired audio signal output by the primary power amplifier device corresponding to the speaker. The present embodiment does not set any limit to this.
Step 203: and generating a first whisper amplifying instruction.
It will be appreciated that the purpose of this step may be to determine for the processor to activate a second amplification of the once amplified audio signal by generating a first whispering gallery amplification instruction. The specific content of the first whisper amplification instruction can be set by a designer, and the embodiment does not limit the specific content as long as the processor can determine that the secondary amplification needs to be performed on the audio signal by using the secondary power amplifier according to the first whisper amplification instruction.
Step 204: and according to the first whisper amplifying instruction, inputting the acquired audio signal output by the first-stage power amplifier device corresponding to the loudspeaker into the second-stage power amplifier device corresponding to the loudspeaker, so that the loudspeaker plays the audio signal output by the second-stage power amplifier device after secondary amplification.
It can be understood that, in this embodiment, the second-stage power amplifying device corresponding to the speaker is used to amplify the voice of the user wearing the earphone, that is, the amplification factor of the second-stage power amplifying device corresponding to the speaker in this step is greater than 1, and the speaker corresponding to the audio signal after the first amplification can be used to play the voice through the second amplification.
Specifically, the specific manner of playing the audio signal output by the secondary power amplifier device and amplified by the speaker in this step may be set by the designer, as shown in fig. 3, when the processor and the secondary power amplifier device are set between the speaker and the primary power amplifier device, the secondary power amplifier device may directly send the output audio signal amplified by the secondary power amplifier device to the speaker. The present embodiment does not set any limit to this.
In the embodiment of the invention, the whisper amplifying function can be intelligently identified and activated by judging whether the audio signal is lower than the threshold value, so that the user experience is improved.
It can be understood that, the above embodiments are all shown by taking amplifying or reducing the speech sound of the earphone wearer as an example, in order to further improve the speech quality of the normal volume call of the earphone wearer in a special scene, the speech sound of the earphone wearer can also be amplified or reduced in the special scene, so as to ensure that the talker at the opposite end can receive the audio signal of the normal volume call. Based on the above embodiments, please refer to fig. 4, and fig. 4 is a flowchart of another whisper amplifying method according to an embodiment of the present invention. The method can comprise the following steps:
step 301: and acquiring a second whisper amplifying instruction.

Step 302: and carrying out secondary amplification on the voice signal which is acquired by the microphone in the earphone and subjected to primary amplification according to the acquired second whisper amplification instruction.
It can be understood that the purpose of this step may be to perform secondary amplification on the audio signal (such as a voice signal input to an analog-to-digital converter in the prior art) acquired by the microphone after primary amplification by the processor in the headset according to the acquired second whisper amplification instruction, so as to perform secondary amplification on the user voice acquired by the microphone, thereby ensuring that the voice heard by the opposite end of the headset wearer during the conversation can be normal volume, and ensuring the conversation quality of both parties during the conversation.
Specifically, as to the specific way in which the processor performs the secondary amplification on the primarily amplified voice signal collected by the microphone in the earphone according to the second whisper amplification instruction obtained in this step, a way corresponding to the way in which the primarily amplified voice signal to be played by the speaker in the earphone is secondarily amplified according to the first whisper amplification instruction in the above-mentioned embodiment may be adopted, as shown in fig. 5 and fig. 6, when the processor (whisper recognition chip), the secondary power amplifier device (secondary power amplifier) corresponding to the speaker and the secondary power amplifier device (secondary power amplifier) corresponding to the microphone are arranged between the speaker and the corresponding primary power amplifier device (primary power amplifier) and between the primary power amplifier device (primary power amplifier) corresponding to the microphone and the analog-to-digital converter, the microphone in the earphone may first send the collected voice signal (analog signal) corresponding to the primary power amplifier device corresponding to the microphone, and then the processor sends the acquired voice signal output by the primary power amplifier device to a secondary power amplifier device corresponding to the microphone for secondary amplification according to the comparison between the voice signal output by the primary power amplifier device and the corresponding threshold value when the voice signal is smaller than the threshold value, and finally the voice signal after secondary amplification is input into the analog-to-digital converter to be converted into a voice signal (digital signal).
In this embodiment, according to the second whisper amplification instruction, the once amplified voice signal collected by the microphone in the earphone is amplified for the second time, so that the opposite end of the call of the earphone wearer can hear the voice signal after the second amplification, and the earphone can raise or lower the volume of the sound collected by the microphone for the second time in a special scene, thereby further realizing the whisper amplification function in the special scene and ensuring the call quality of the normal volume call of both parties in the special scene.
