Abstract
The invention discloses an earphone interface compatible with a microphone function. The earphone interface comprises an earphone socket (2) and a seal device (3); a microphone (6) is arranged in the seal device (3), and the earphone socket (2) and the seal device (3) are fixedly mounted on a printed circuit board (1) respectively; a sound transmission hole (4) is formed in the earphone socket (2) close to the seal device (3); a sound picking hole (5) matched with the sound transmission hole (4) is formed in the seal device (3) close to the earphone socket (2). According to the invention, the sound transmission hole in the earphone interface is used as the sound picking hole for denoising MIC, so that the double-microphone denoising function is achieved without arranging additional sound picking hole in a cellphone casing, and the machining difficulty of the cellphone casing is reduced; the earphone interface does not affect the functions of the cellphone including anti-dust, anti-static and the like, is easy to implement, and is suitable for various cellphones.
Description
Technical field
The present invention relates to a kind of electronic product, particularly relate to a kind of earphone interface of compatible microphone function.
Background technology
Mobile phone, have another name called mobile phone, is a kind of portable telephone terminal that can use in the broader context.The development speed of mobile phone is rapid, and short 40 years, mobile phone has just developed into the 4G epoch.Present mobile phone except the most basic call function, can also be used to receiving and dispatching mail and short message, surfs the Net, plays games, takes pictures and sees a film etc.Now, mobile phone has become very important instrument in people's life.
Yet people when using the mobile phone various functions, are usually perplexed by some problems, such as: there is no in the charge condition situation not have suddenly electricity, cell phone capacity is little, touch screen malfunctioning and noise etc. suddenly, wherein the impact of noise on human is the most frequently.Noise is present in communication process, Recording Process, music process and video display process.The mobile phone noise mainly contains two kinds of internal noise and external noises, and internal noise is produced by circuit itself, and external noise produces due to the residing environment of people, and which kind of noise all can produce certain impact when people use mobile phone.
Chinese patent application number: 200620022811.2, a kind of mobile phone of turnover pickup is disclosed, its MIC physical location as shown in Figure 1, it comprises two MIC, MIC1 is arranged on the end of mobile phone, MIC2 is arranged on clamshell phone line centered by cover turnover shaft A, near in the two side areas of this cover turnover shaft, or the middle section position of bar phone, the back side.This patent arranges two MIC pickup holes on phone housing, the acting in conjunction by two MIC pickup hole internal circuits reaches decrease of noise functions.
In prior art, most mobile phones are utilize said structure and in conjunction with related circuit, mobile phone carried out noise abatement and process, and this structure can effectively reach noise reduction effect.But, this structure need to arrange at least two pickup holes on hand set machine shell, this has not only increased difficulty of processing and the production cost of hand set machine shell, and for airborne dust and liquid suspension enter interior of mobile phone, provide more passage, thereby affect various performances and the useful life of mobile phone.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, when providing a kind of and not changing cell phone appearance, not reducing dustproof and electrostatic-proof function, earphone interface that again can compatible newly-increased microphone pickup.
The objective of the invention is to be achieved through the following technical solutions: a kind of earphone interface of compatible microphone function, it comprises earphone socket and sealing device, microphone is arranged in sealing device, earphone socket and sealing device are fixedly mounted on respectively on printed circuit board, earphone socket is provided with continuant orifice near a side of sealing device, and sealing device is provided with the pickup hole of with continuant orifice, matching near a side of earphone socket.
Described microphone is electret microphone or silicon micro-microphone.
The invention has the beneficial effects as follows:
1. utilize the pickup hole of the continuant orifice of earphone socket inside as noise reduction MIC, when reaching the diamylose decrease of noise functions, need to not set up extra pickup hole on hand set machine shell, thereby reduced the difficulty of processing of hand set machine shell;
2. make airborne dust and liquid suspension be difficult for entering into interior of mobile phone, guaranteed reliability and the stability of operating handset, extended the useful life of mobile phone;
3. this invention can not reduce the functions such as dustproof and antistatic of mobile phone, and it is convenient to implement, and is applicable to all kinds of mobile phones.

Embodiment
Below in conjunction with accompanying drawing, technical scheme of the present invention is described in further detail, but protection scope of the present invention is not limited to the following stated.
As shown in Figure 2, a kind of earphone interface of compatible microphone function, it comprises earphone socket 2 and sealing device 3, and microphone 6 is arranged in sealing device 3, and earphone socket 2 and sealing device 3 are fixedly mounted on respectively on printed circuit board 1.
As described in Figure 3, be provided with microphone 6 in described sealing device 3, microphone 6 is placed in the middle part of sealing device 3, the wire hole of microphone is sealed with soft silica gel 7, be provided with the thick soft rubber of 1.5mm 8 in the periphery of microphone 6, be provided with the thick housing of one deck 1mm 9 in the outside of soft rubber 8, this housing is that hard plastic glue is made; Be provided with a pickup hole 5 on the surface of sealing device 3, the diameter in this pickup hole 5 is more than or equal to 1/2 of the diameter of microphone 6.After being arranged on sealing device 3 on printed circuit board, with silica gel 10, further seal, make cavity of sealing device 3 inner formation, guaranteed the pickup effect of microphone 6.
Described microphone 6 is electret microphone or silicon micro-microphone.
As shown in Figure 4, earphone socket 2 is provided with continuant orifice 4 near a side of sealing device 3, sealing device 3 is provided with the pickup hole 5 of with continuant orifice 4, matching near a side of earphone socket 2, continuant orifice 4 setting of aliging with pickup hole 5, thereby make earphone jack also can use as the pickup hole, therefore do not need to offer again extra pickup hole on hand set machine shell.
As shown in Figure 5, be the present invention's schematic diagram in kind, main MIC1 is arranged on the mobile phone bottom, the receiver J-Horner 11 of compatible noise reduction MIC is arranged on the mobile phone top, make between the MIC1 of winner and noise reduction MIC and be independent of each other, on cell phone mainboard, be provided with the Dolby circuit corresponding with main MIC1 and noise reduction MIC.
MIC1 and noise reduction MIC, one is mainly used in keeping stable conversation clearly, and one is used for initiatively eliminating noise.Mike, by after collecting extraneous sound, after processing, sends the sound wave opposite with noise, utilizes principle of cancellation to eliminate noise, i.e. after noise reduction MIC sampling, with after the waveform paraphase with the overlapping function that can realize noise reduction of microphone sampling.
