图1是根据本发明实施例的耳机在一次使用中的音量调节方法的流程示意图。 1 is a flow chart showing a method of adjusting a volume of a headphone in one use according to an embodiment of the present invention.
根据图1所示，本发明的用于耳机的音量调节方法包括：According to FIG. 1, the volume adjustment method for an earphone of the present invention includes:
步骤S110，接收到耳机开启信号后，查询使用该耳机记录的音量调节历史数据。Step S110, after receiving the headset on signal, query the volume adjustment history data recorded by the headset.
根据该步骤S110，本发明耳机在使用时会根据经由音量调节电路输入的音量调节信号记录音量调节历史数据。According to this step S110, the earphone of the present invention records the volume adjustment history data in accordance with the volume adjustment signal input via the volume adjustment circuit when in use.
该音量调节信号可以包括音量增加调节信号和音量减小调节信号。The volume adjustment signal may include a volume increase adjustment signal and a volume decrease adjustment signal.
该音量增加调节信号和音量减小调节信号可以是脉冲信号。以音量增加调节信号为例，接收到一个脉冲，对应一次音量增加调节。The volume up adjustment signal and the volume down adjustment signal may be pulse signals. Taking the volume increase adjustment signal as an example, a pulse is received, which corresponds to a volume increase adjustment.
因此，该音量调节历史数据可以包括音量增加调节次数的累加数据和音量减小调节次数的累加数据，这可以但不局限于通过以下两个具体例子实现。Therefore, the volume adjustment history data may include accumulated data of the volume increase adjustment number and accumulated data of the volume reduction adjustment number, which may be, but is not limited to, implemented by the following two specific examples.
例子1：这可以是设置音量增加调节计数器和音量减少调节计数器，且设置音量增加调节计数器和音量减少调节计数器的初始计数值均为0，每接收到一个音量增加调节脉冲，则使得音量增加调节计数器的计数值Ci加1，而每接收到一个音量减少调节脉冲，则使得音量减少调节计数器的计数值Cj加1。Example 1: This can be set the volume up adjustment counter and the volume decrease adjustment counter, and the initial count value of the set volume increase adjustment counter and the volume decrease adjustment counter are both 0, and each time a volume increase adjustment pulse is received, the volume is adjusted and adjusted. The counter value Ci of the counter is incremented by 1, and each time a volume reduction adjustment pulse is received, the count value Cj of the volume reduction adjustment counter is incremented by one.
例子2：这也可以设置音量调节计数器，且设置音量调节计数器的初始计数值为0，每接收到一个音量增加调节脉冲，则使得音量调节计数器的计数值Cm加1，而每接收到一个音量减少调节脉冲，则使得音量调节计数器的计数值Cm减1。Example 2: This can also set the volume adjustment counter, and set the initial count value of the volume adjustment counter to 0. Each time a volume increase adjustment pulse is received, the count value Cm of the volume adjustment counter is incremented by one, and each time a volume is received. Decreasing the adjustment pulse reduces the count value Cm of the volume adjustment counter by one.
该耳机开启信号可以包括上电信号、通过按键输入的开始播放信号等等。The headphone turn-on signal may include a power-on signal, a start-up signal input through a button, and the like.
步骤S120，根据音量调节历史数据确定最新音量值。In step S120, the latest volume value is determined according to the volume adjustment history data.
在该步骤S120中，最新音量值即为最近使用的音量值。在接收到耳机开启信号后最初确定的最新音量值即为上一次使用该耳机的最终音量值。In this step S120, the latest volume value is the most recently used volume value. The latest volume value initially determined after receiving the headset on signal is the final volume value of the last time the headset was used.
该步骤S120可以进一步包括：The step S120 may further include:
步骤S121，根据音量调节历史数据确定最新音量调节值ΔV。In step S121, the latest volume adjustment value ΔV is determined based on the volume adjustment history data.
在上述例子1中，最新音量调节值ΔV＝(Ci-Cj)×Vp公式(1)； In the above example 1, the latest volume adjustment value ΔV = (Ci - Cj) × V p formula (1);
其中，Vp为每进行一次音量调节(包括音量增加调节和音量减少调节)对应的音量调节量。Among them, V p is the volume adjustment amount corresponding to each volume adjustment (including volume increase adjustment and volume reduction adjustment).
在上述例子2中，最新音量调节值ΔV＝Cm×Vp。In the above example 2, the latest volume adjustment value ΔV = Cm × V p .
步骤S122，计算最新音量调节值与设定的基准音量值的矢量和作为所述最新音量值。Step S122, calculating a vector sum of the latest volume adjustment value and the set reference volume value as the latest volume value.
该矢量和表示步骤S122中的计算需要考虑数值的正、负符号。The vector sum represents the positive and negative signs of the value to be considered in the calculation in step S122.
该设定的基准音量值即为耳机出厂时设置的播放音量值。The set reference volume value is the playback volume value set when the headset is shipped from the factory.
在上述例子1中，如果音量增加调节计数器的计数值Ci大于音量减少调节计数器的计数值Cj，则最新音量调节值为正值，最新音量值需要在基准音量值的基础上增加最新音量调节值；如果音量增加调节计数器的计数值Ci小于音量减少调节计数器的计数值Cj，则最新音量调节值为负值，最新音量值需要在基准音量值的基础上减去最新音量调节值；如果音量增加调节计数器的计数值Ci等于音量减少调节计数器的计数值Cj，则最新音量值将等于基准音量值。In the above example 1, if the count value Ci of the volume increase adjustment counter is larger than the count value Cj of the volume decrease adjustment counter, the latest volume adjustment value is a positive value, and the latest volume value needs to increase the latest volume adjustment value based on the reference volume value. If the count value Ci of the volume increase adjustment counter is smaller than the count value Cj of the volume decrease adjustment counter, the latest volume adjustment value is a negative value, and the latest volume value needs to subtract the latest volume adjustment value based on the reference volume value; if the volume is increased The count value Ci of the adjustment counter is equal to the count value Cj of the volume reduction adjustment counter, and the latest volume value will be equal to the reference volume value.
在上述例子2中，如果音量调节计数器的计数值Cm大于0，则最新音量值需要在基准音量值的基础上增加最新音量调节值；如果音量调节计数器的计数值Cm小于0，则最新音量值需要在基准音量值的基础上减去最新音量调节值；如果音量调节计数器的计数值Cm等于0，则最新音量值将等于基准音量值。In the above example 2, if the count value Cm of the volume adjustment counter is greater than 0, the latest volume value needs to increase the latest volume adjustment value based on the reference volume value; if the count value Cm of the volume adjustment counter is less than 0, the latest volume value The latest volume adjustment value needs to be subtracted from the reference volume value; if the volume adjustment counter's count value Cm is equal to 0, the latest volume value will be equal to the reference volume value.
进一步地，为了防止播放音量超过安全值而造成耳膜损失，该步骤S120可进一步包括：判断最新音量调节值是否超过设定的调节值上限，如是，则计算调节值上限与设定的基准音量值的之和作为所述最新音量值，如否，则计算最新音量调节值与设定的基准音量值的矢量和作为所述最新音量值。Further, in order to prevent the eardrum from being lost due to the playback volume exceeding the safe value, the step S120 may further include: determining whether the latest volume adjustment value exceeds the set adjustment value upper limit, and if so, calculating the adjustment value upper limit and the set reference volume value. The sum of the sum is the latest volume value, and if not, the vector sum of the latest volume adjustment value and the set reference volume value is calculated as the latest volume value.
步骤S130，根据最新音量值对接收到的音频信号进行音量调节处理及播放控制。Step S130, performing volume adjustment processing and playback control on the received audio signal according to the latest volume value.
根据该步骤S130，耳机的扬声器将以最新音量值播放接收到的音频信号，这说明在开启耳机后，耳机将以上一次使用耳机的最终音量值开始进行播放。 According to the step S130, the speaker of the earphone will play the received audio signal with the latest volume value, which means that after the earphone is turned on, the earphone starts to play the final volume value of the previous use of the earphone.
步骤S140，在播放音频信号期间，接收耳机的音量调节电路输出的音量调节信号。Step S140, receiving a volume adjustment signal output by the volume adjustment circuit of the earphone during the playing of the audio signal.
该音量调节电路可以是按键电路、触控调节电路、非接触的感应调节电路等等。The volume adjustment circuit can be a button circuit, a touch adjustment circuit, a non-contact induction adjustment circuit, and the like.
根据该步骤S140，用户可以在播放音频信号期间，通过音量调节电路进行音量调节。According to this step S140, the user can perform volume adjustment by the volume adjustment circuit during the playback of the audio signal.
步骤S150，根据音量调节信号更新音量调节历史数据，以使本次使用结束时能够通过音量调节历史数据反映本次使用结束时的最终音量值。In step S150, the volume adjustment history data is updated according to the volume adjustment signal, so that the final volume value at the end of the current use can be reflected by the volume adjustment history data at the end of the current use.
之后，可以回到步骤S110进行下一次查询，以在接收到音量调节信号后重新确定最新音量值。Thereafter, it is possible to return to step S110 for the next inquiry to re-determine the latest volume value after receiving the volume adjustment signal.
该音量调节历史数据被存储在非易失性存储器中，以在掉电后仍能保存数据不丢失。The volume adjustment history data is stored in a non-volatile memory to preserve data without loss after power down.
由此可见，根据本发明的音量调节方法，本发明耳机将能够独立进行音量调节，并且能够通过记录音量调节历史数据进行音量记忆，因此能够在开启耳机后直接以上一次使用耳机的最终音量值开始播放音频信号，进而可以避免用户在每次使用耳机时均需要进行音量调节。It can be seen that, according to the volume adjustment method of the present invention, the earphone of the present invention can independently perform volume adjustment, and can perform volume memory by recording volume adjustment history data, so that the final volume value of the earphone can be directly used after the earphone is turned on. The audio signal is played, which prevents the user from having to adjust the volume each time the headset is used.
