Embodiment 1

[0046] The embodiment of the present invention provides a volume control method for earphones. The method provided in this embodiment can be applied to earphones using the Type-C interface. In order to facilitate a better understanding of the embodiments of the present invention, the Type-C interface is described below Give a brief introduction.

[0047] figure 1 A schematic diagram of the Type-C interface provided by the embodiment of the present invention, the Type-C interface can be used for interconnection between the earphone and the terminal device, wherein, such as figure 1 As shown, the Dp and Dn pins are respectively used as input pins of the left and right conversion units of the earphone, and the CC pin is a functional pin of the earphone, which can be used to transmit control signals.

[0048] For the earphone volume control method provided by the embodiment of the present invention, please refer to figure 2 , which is a schematic flow chart of the method provid...

Embodiment 2

[0067] Embodiments of the present invention provide device embodiments for implementing the steps and methods in the above method embodiments.

[0068] Figure 4 A schematic structural diagram of an earphone volume control device provided in Embodiment 2 of the present invention, as shown in Figure 4 As shown, the device includes: an acquisition module 41 , a modulation module 42 and an output module 43 .

[0069] The acquisition module 41 is configured to respectively acquire the preset volumes of the conversion units of the earphone.

[0070] The modulation module 42 is configured to modulate the audio signals to be played according to respective preset volumes to obtain output audio signals.

[0071] The output module 43 is configured to output each output audio signal to a corresponding conversion unit.

[0072] Further, the modulation module 42 is also configured to modulate the audio signal to be played according to the preset volume of the earphone when it is detect...

Embodiment 3

[0080] Embodiment 3 of the present invention provides a terminal device, including the headphone volume control device provided in Embodiment 2. The terminal device has a Type-C interface corresponding to the earphone, and is used to output an audio signal to the earphone, so that the earphone sends out audio according to the audio signal.

[0081] Specifically, after obtaining the preset volumes of the conversion units of the earphones, the terminal device modulates the audio signals to be played according to the preset volumes to obtain the output audio signals, and outputs the output audio signals to the corresponding conversion units respectively. , so that the conversion units of the earphone have different volumes respectively, which overcomes the technical problem in the prior art that the two conversion units cannot have different volumes respectively.

[0082] Those skilled in the art can clearly understand that for the convenience and brevity of the description, the ...

Abstract

The embodiments of the invention provide an earphone volume control method and apparatus, and a terminal device. After preset volume of each conversion unit of an earphone is obtained, audio signals to be played are modulated according to each preset volume, each output audio signal is obtained, each output audio signal is output to the corresponding conversion unit, each conversion unit of the earphone is enabled to have different volume, and thus the technical problem of incapability of enabling two conversion units to respectively have different volume in the prior art is overcome.

Description

【Technical field】 [0001] The present invention relates to the field of electronic technology, in particular to an earphone volume control method, device and terminal equipment. 【Background technique】 [0002] An earphone is a commonly used audio output device, which generally includes a pair of conversion units, and each conversion unit can convert a received electrical signal into an audible sound wave through a speaker. [0003] In the course of realizing the present invention, the inventor finds that there are at least the following problems in the prior art: [0004] In the prior art, the two conversion units of the earphone perform audio output according to the same electrical signal, so that the audio volumes output by the two conversion units are the same. When two users use the same pair of earphones and need to adjust the volume independently, or the users who use the earphones are a special group, and the hearing of the left and right ears is different, the existi...
