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
The present invention relates to a kind of mobile phone auxiliary equipment, fourth inserted by especially a kind of earphone facilitating Mobile phone talkback to operate.
Background technology
Existing mobile phone is equipped with the earphone jack (earphone interface) supporting with headset plug, be provided with central processing unit at interior of mobile phone simultaneously, memory cell and radio communication unit is connected to central processing unit, also be connected to audio coding/decoding device and audio frequency output selector switch with central processing unit simultaneously, audio coding/decoding device is connected with audio frequency output selector switch by audio amplification unit, and audio frequency output selector switch connects with boombox and earphone interface; Earphone interface connects with audio coding/decoding device, is also connected to built-in microphone with audio coding/decoding device.During call, the voice of first speaker are sent by built-in microphone, audio coding/decoding device, central processing unit, radio communication unit successively; The other side's voice, then by radio communication unit, central processing unit, audio coding/decoding device, audio amplification unit, audio frequency output selector switch, are exported by boombox or earphone interface then.At present, mobile phone has realized the function of intercom by software (as micro-letter software), but each intercommunication operation all needs to open corresponding software interface, very inconvenient.
Summary of the invention
The present invention is the above-mentioned technical problem in order to solve existing for prior art, provides a kind of earphone facilitating Mobile phone talkback to operate to insert fourth.
Technical solution of the present invention is: fourth inserted by a kind of earphone facilitating Mobile phone talkback to operate, have headset plug, it is characterized in that: be provided with microphone, microphone connects with coupling circuit, coupling circuit one tunnel directly connects with headset plug, and button of separately leading up to connects with headset plug.
The present invention, without the need to opening corresponding software interface, only needs one-handed performance button can realize Mobile phone talkback function, very convenient, is especially convenient to the uses such as driver.
Accompanying drawing explanation
Fig. 1 is the schematic block circuit diagram of the embodiment of the present invention.
Fig. 2 is the structural representation of the embodiment of the present invention.
Fig. 3 is the operation principle schematic diagram of the embodiment of the present invention.
Embodiment
As shown in Figure 1, 2, have headset plug 4, be provided with microphone 1, microphone 1 connects with coupling circuit 2, and coupling circuit 2 one tunnel directly connects with headset plug 4, and button 3 of separately leading up to connects with headset plug 4.
Implementation method is as shown in Figure 3:
When needing intercommunication, headset plug is inserted in the earphone jack of mobile phone.
After central processing unit identification headset plug inserts, first audio frequency output selector switch is switched to earphone interface, control audio decoder simultaneously and send the characteristic signal that frequency is fx, by external headphones interface, button after audio amplification unit, be transported to coupling circuit.The output signal A of coupling circuit enters central processing unit by headset plug, earphone interface, audio decoder, central processing unit utilizes fast Fourier (FFT) to convert, time domain speech signal is resolved into frequency-region signal, and then extraction frequency is the signal of fx and analyzes the change of its amplitude.When button is pressed, fx frequency signal amplitude arrives predetermined amplitude and keeps, then by the target signal filter of fx frequency corresponding in synthetic speech signal frequency domain, and utilize quick inversefouriertransform (IFFT) algorithm that frequency-region signal is converted to time domain speech signal again, the recording process of opening voice signal simultaneously; After unclamping button, fx frequency signal disappears or reduces suddenly, then stop Speech processing and the process of recording, the voice signal recorded preserved with file mode and is sent to designated user (holding the other side of the present invention) by wireless network, realizing intercommunication function.
When receiving the intercommunication information from the other side, controlling audio frequency output selector switch to boombox by central processing unit, and intercommunication information is outputted to boombox sounding by audio amplification unit after audio decoder.
Claims (1)
