Embodiment 1

[0028] Embodiment 1 of the present invention provides a solution to obtain the corresponding signal gain value by obtaining the pressure between the earphone and the ear, and adjust the audio signal gain value output by the earphone according to the obtained signal gain value to improve the sound quality of the earphone. as follows:

[0029] Such as figure 1 As shown, the method for improving the sound quality of earphones in Embodiment 1 of the present invention, the method includes:

[0030] Step 101, detecting the pressure between the earphone and the ear contact surface to obtain a pressure value.

[0031] The pressure value is used to adjust the gain value of the audio signal output by the earphone, and generally ranges from 0 to 8N.

[0032] Step 102, according to the preset corresponding relationship between pressure and signal gain, determine the obtained signal gain value corresponding to the pressure value.

[0033] Wherein, the corresponding relationship between ...

Embodiment 2

[0050] The method for improving the sound quality of earphones provided by Embodiment 2 of the present invention (taking low-frequency signals as an example) is as follows:

[0051] Such as image 3 As shown, by adding a pressure sensor 302 on the periphery of the existing earphone head 301 (the pressure sensor 302 can be arranged in the earphone head, and then a through hole is set on the earphone head 301, the pressure sensor 302 is exposed through this through hole, and then contact with the human ear), to detect the airtightness between the headphone head 301 and the human ear when it is inserted into the ear, and according to the result detected by the pressure sensor 302, it is fed back to the control terminal, and the gain of the earphone output signal is increased to compensate for the sealing A poor level will leak the lost acoustic signal, thereby improving the sound quality and sense of hearing.

[0052] In order to obtain a better user experience, the material of ...

Embodiment 3

[0072] Such as Image 6 As shown, the mobile terminal in Embodiment 3 of the present invention includes:

[0073] The first detection module 601 is configured to detect the pressure between the earphone and the contact surface of the ear to obtain a pressure value.

[0074] The pressure value is used to adjust the gain value of the audio signal output by the earphone, and generally ranges from 0 to 8N.

[0075] The determining module 602 is configured to determine the obtained signal gain value corresponding to the pressure value according to the preset corresponding relationship between pressure and signal gain.

[0076] Wherein, the corresponding relationship between the preset pressure and the signal gain can be obtained through the preliminary test, and the signal gain can be a target gain (a gain that needs to be adjusted to be achieved), or a gain that needs to be compensated.

[0077] An adjustment module 603, configured to adjust the audio signal gain value output by...

Abstract

The invention provides a method for improving sound quality of a headset. The method comprises the following steps: detecting a pressure between contact surfaces of the headset and ears so as to obtain a pressure value; determining a signal gain value corresponding to the obtained pressure value according to a corresponding relationship between a preset pressure and a signal gain; and adjusting an audio signal gain value output by the headset according to the signal gain value. The invention also provides a mobile terminal. According to the method provided by the invention, the signal gain value corresponding to the detected pressure value can be determined according to the corresponding relationship between the preset pressure and the signal gain, and the audio signal gain value output by the headset is adjusted according to the signal gain value in order to improve the sound quality of the headset. The aim of performing compensation on audio leakage generated due to an insufficient fit degree between the headset and human ears is fulfilled; an ideal sound quality effect can be achieved in different wearing states of a user; the auditory feeling is improved; and wearing discomfort due to a structural sealing design is avoided.

Description

technical field [0001] The present invention relates to the technical field of communication, and more specifically, to a method for improving sound quality of earphones and a mobile terminal. Background technique [0002] With the rapid development of mobile smart terminals, current mobile phones integrate more and more functions. In order to bring the ultimate user experience, the technical indicators of some functions have also been greatly improved. Taking music as an example, the current smart terminal integrated with Hi-Fi (High-Fidelity, high-fidelity) elements can provide users with sound quality enjoyment that is basically comparable to that of existing high-end music players. But good sound quality is determined by many aspects, including the choice of music source, the design of the circuit, etc. Of course, it is also inseparable from the earphones that match the smart terminal. [0003] At present, the earphones equipped with smart terminals are basically in-ear...
