Problems solved by technology

[0002] When the user uses the earphones, the environmental noise will generally affect the user's earphone use effect, and the output audio signal will generally be adjusted to make the sound pressure of the earphones within the comfortable sound pressure range; however, because the user often manually increases the volume or environmental memory In sharp environmental signals, the sound pressure of the output audio signal increases beyond the comfortable sound pressure range, resulting in damage to the user's ears

Embodiment 2

[0063] Embodiment 2 of the control method for the earphone of the present invention is proposed based on Embodiment 1. In this embodiment, after step S20, it also includes

[0064] When the sound pressure level is within a preset comfortable sound pressure level range, acquiring the duration of the sound pressure level;

[0065] When the duration is longer than a preset duration, reduce the amplitude of the audio signal to be played;

[0066] controlling the speaker of the earphone to output the audio signal to be played after the amplitude is reduced

[0067] Since the duration of the user's ears in the same sound pressure environment is longer than the preset time, the user's ears will also be damaged. Therefore, when the user is in the same sound pressure environment for a long time, the sound pressure level in the environment can be adjusted. When adjusting, in order to avoid damage to the user's hearing, the amplitude of the target audio signal is often reduced to reduce...

Embodiment 3

[0071] refer to image 3 Based on Embodiment 1 or Embodiment 2, Embodiment 3 of the control method of the headset of the present invention is proposed. In this embodiment, the control method of the headset further includes:

[0072] Step S50, collecting environmental noise signals in real time or at regular intervals;

[0073] Step S60, determining a reference noise signal according to the current operating mode of the earphone and the environmental noise signal;

[0074] Step S70, controlling the speaker to output an inverse signal of the reference noise signal for noise reduction.

[0075] In the technical solution disclosed in this embodiment, noise reduction processing can be performed on the earphone to improve user experience while reducing environmental noise in the audio signal collected by the microphone. During noise reduction, the phase of the output reverse signal is opposite to that of the reference noise signal. A microphone can be arranged in the shell or the ...

Embodiment 4

[0079] refer to Figure 4 Embodiment 4 of the control method for the earphone of the present invention is proposed based on the third embodiment. In this embodiment, the earphone includes a gesture sensor, and the control method for the earphone further includes:

[0080] Step S80, acquiring sensor data detected by the gesture sensor, and determining gesture parameters according to the sensor data;

[0081] Step S90, acquiring the target mode of the earphone according to the gesture parameter;

[0082] Step S100, controlling the earphone to switch to the target mode.

[0083] In the technical solution disclosed in this embodiment, the gesture sensor may include an ultrasonic sensor, a vibration sensor or a touch sensor, and a fingerprint acquisition module may be integrated in the gesture sensor to identify the identity of the user.

[0084] The following ultrasonic fingerprint sensor is taken as an example (refer to the ultrasonic fingerprint sensor for the implementation p...

Abstract

The invention discloses an earphone and an earphone control method, and the method comprises the steps: obtaining an output audio signal in real time or at regular time, wherein the output audio signal comprises an audio signal outputted by a loudspeaker of the earphone; acquiring a sound pressure level of the output audio signal; when the sound pressure level exceeds a preset comfortable sound pressure level interval, processing the audio signal to be played according to a target amplitude corresponding to the comfortable sound pressure level interval; and controlling the loudspeaker to output the processed audio signal to be played. According to the invention, when the sound pressure level of the collected audio signal exceeds the preset sound pressure level interval, the audio signal tobe output is adjusted, so that the output audio signal is located in the comfortable sound pressure level interval, and the hearing damage of the earphone to the ears of the user is reduced.

Description

technical field [0001] The invention relates to the field of earphones, in particular to an earphone control method and the earphone. Background technique [0002] When the user uses the earphones, the environmental noise will generally affect the user's earphone use effect, and the output audio signal will generally be adjusted to make the sound pressure of the earphones within the comfortable sound pressure range; however, because the user often manually increases the volume or environmental memory In the case of sharp environmental signals, the sound pressure of the output audio signal increases beyond the comfortable sound pressure range, resulting in damage to the user's ears. Contents of the invention [0003] The main purpose of the present invention is to provide an earphone control method and the earphone, aiming at reducing the damage to the user's ear by adjusting the sound pressure of the earphone. [0004] In order to achieve the above object, the present inv...
