Embodiment Construction

[0009] Such as figure 1 , 2 As shown, there is an earphone plug 4 and a microphone 1 is provided. The microphone 1 is connected to the coupling circuit 2 .

[0010] Implementation methods such as image 3 Shown:

[0011] When intercom is required, insert the earphone plug into the earphone jack of the mobile phone.

[0012] After the central processing unit recognizes that the headphone plug is inserted, it first switches the audio output selection switch to the headphone jack, and at the same time controls the audio decoder to send out a characteristic signal of frequency fx, which is sent to the coupling circuit through the external headphone jack and buttons after passing through the audio amplifier unit. The output signal A of the coupling circuit enters the central processing unit through the headphone plug, headphone jack and audio decoder, and the central processing unit uses fast Fourier transform (FFT) to decompose the time-domain speech signal into a frequency-dom...

Abstract

The invention discloses an earphone insert pin convenient for mobile phone talkback operation. The earphone insert pin is provided with an earphone plug (4), and is characterized by being provided with a microphone (1), wherein the microphone (1) is connected with a coupling circuit (2); one path of the coupling circuit (2) is directly connected with the earphone plug (4); and the other path of the coupling circuit (2) is connected with the earphone plug (4) through a key (3). A mobile phone talkback function can be realized conveniently by only operating the key with a single hand. In particular, mobile phone talkback is realized conveniently for drivers and the like.

Description

technical field [0001] The invention relates to an auxiliary device for a mobile phone, in particular to an earphone plug which is convenient for the intercom operation of the mobile phone. Background technique [0002] Existing mobile phones are all equipped with earphone jacks (earphone jacks) that are matched with earphone plugs. At the same time, a central processing unit is arranged inside the mobile phone, and a storage unit and a wireless communication unit are connected with the central processing unit. Connected with audio coder / decoder and audio output selection switch, audio coder / decoder is connected with audio output selection switch through audio amplifier unit, audio output selection switch is connected with built-in speaker and headphone jack; headphone port is connected with audio coder / decoder The device is connected with the audio coder / decoder and has a built-in microphone. During a call, the caller’s voice is sent through the built-in microphone, audio ...
