Embodiment 1

[0032] refer to figure 1 , which shows a flow chart of a sound quality compensation method according to an embodiment of the present invention, which is applied to a mobile terminal, and the method may specifically include the following steps:

[0033] Step 101, outputting a first audio signal through a speaker, wherein the first audio signal carries an infrasound wave signal.

[0034] Specifically, in the embodiment of the present invention, when the user is using the earphone, the mobile terminal can amplify the analog audio signal through its codec, power amplifier and other modules, and drive the speaker to output the first audio Signal.

[0035] In an embodiment of the present invention, the first audio signal carries an infrasound wave signal. That is, when the user uses the earphone to listen to sound, the audio played in the earphone includes infrasound wave signals in addition to music. In the embodiment of the present invention, the frequency of the infrasonic sig...

Embodiment 2

[0049] refer to figure 2 , which shows a flowchart of a sound quality compensation method according to another embodiment of the present invention, which may specifically include the following steps:

[0050] Step 201 , in a scene where the simulated earphone is in a standard wearing state, according to the infrasound signal collected by the microphone and output by the speaker, a standard amplitude value corresponding to the infrasound signal is obtained.

[0051] Specifically, in the embodiment of the present invention, the operator can normally wear the earphone with a standard human ear canal, thereby simulating a scene where the earphone is in a standard wearing state. In this scenario, the mobile terminal can amplify the analog audio signal through its codec, power amplifier and other modules to send the infrasonic signal to the speaker, and the speaker vibrates and radiates the infrasonic signal after receiving the signal.

[0052] In the embodiment of the present inv...

Embodiment 3

[0095] refer to image 3 , shows a block diagram of a mobile terminal according to an embodiment of the present invention. The mobile terminal in the embodiment of the present invention can realize the details of the sound quality compensation method in the first embodiment to the second embodiment, and achieve the same effect. image 3 The illustrated mobile terminal 300 includes:

[0096] The output module 301 is configured to output a first audio signal through a speaker, wherein the first audio signal carries an infrasound wave signal.

[0097] Specifically, in the embodiment of the present invention, when the user uses the earphone, the output module 301 can amplify the analog audio signal through its codec, power amplifier and other modules, and drive the speaker to output the first audio signal.

[0098] In an embodiment of the present invention, the first audio signal carries an infrasound wave signal. That is, when the user uses the earphone to listen to sound, th...

Abstract

The embodiment of the invention provides a tone quality configuration method and a mobile terminal. The method comprises the steps of outputting a first audio signal via a loudspeaker, wherein the first audio signal carries an infrasonic wave signal; according to a second audio signal collected by the microphone, acquiring a target amplitude value corresponding to the infrasonic wave signal; according to the target amplitude value, judging whether the current wearing state of an earphone is a standard wearing state; if no, extracting a locally stored target compensation array set correspondingto the target amplitude value; and performing tone quality compensation on the first audio signal according to the target compensation array set. Therefore, the wearing state of the current earphonecan be monitored during a process that a user uses the earphone, and under the condition that the wearing state is nonstandard, the current tone quality is compensated via the pre-stored compensationarray set, and thus the negative effects on middle and low frequencies when the coupling of the earphone is loosen are effectively improved, and the audition experience of the earphone user is effectively enhanced.

Description

technical field [0001] The invention relates to the technical field of audio processing, in particular to a sound quality compensation method and a mobile terminal. Background technique [0002] Earphones have been widely used in people's daily life and work. Compared with the traditional listening method of using high-fidelity speakers, earphones are small in size and easy to carry, and the listening method does not need a fixed place. With the advancement of micro-speaker technology, many excellent earphones have a very wide and flat frequency response curve, thus ensuring high-fidelity music appreciation, so they are also favored by more and more consumers. However, many manufacturers have They are very concerned about the quality of the earphone itself, but ignore that the user's wearing state of the earphone will also affect the listening effect that the earphone should bring. [0003] According to the survey, consumers usually use earphones for 1-3 hours at a time. D...
