Problems solved by technology

[0003] However, there are some inconveniences in the use of wired earphones. For example, when the user is in a meeting, the wired earphone is plugged into the portable device, and the earpiece of the earphone is also placed in the ear, but when the mobile phone calls, the sound is still It will be output from the speaker of the mobile phone, which will affect the progress of the meeting; for another example, the user originally plugged in the earphone to listen to music, but if he puts the mobile phone on the table and wants to use the speaker to listen to music, he must pull out the earphone to achieve
[0004] In view of the problem in the related art that the use mode cannot be freely switched when using a wired headset, no effective solution has been proposed yet

Abstract

The invention discloses an earphone, user equipment and an audio data output method, wherein the earphone comprises a speaker and an A / D (analog / digital) sampler, the A / D sampler is used for performing sampling on the current impedance of the speaker to get the current voltage of the speaker and feeding back the current voltage to a main controller of the user equipment connected with the earphone. According to the invention, free switching between sound channels can be realized in different user using environments.

Description

technical field [0001] The present invention relates to the communication field, in particular, to an earphone, user equipment and an audio data output method. Background technique [0002] Currently, personal portable devices (for example, multimedia centers, smart phones, etc.) are more and more widely used, and wired earphones become an indispensable accessory during the use of these devices. For example, if figure 1 As shown, for audio data to be played through wired earphones, the main controller (audio data source) first generates audio data and sends the audio data to the power amplifier of the earphone. After the power amplifier amplifies the audio data, it sends it to the speaker of the earphone , so that the electrical signal is converted into an acoustic signal, which can be heard by the human ear. [0003] However, there are some inconveniences in the use of wired earphones. For example, when the user is in a meeting, the wired earphone is plugged into the port...
