Abstract

The utility model discloses a headset interface compatible with a microphone function. The headset interface compatible with the microphone function comprises a headset socket (2) and a sealing device (3); a microphone (6) is arranged in the sealing device (3); the headset socket (2) and the sealing device (3) are respectively fixed on a printed circuit board (1); a sound through hole (4) on the headset socket (2) is arranged near the sealing device (3); and a sound pickup hole (5) on the sealing device (3) is arranged near the headset socket (2) so as to match the sound through hole (4). According to the utility model, the sound though hole inside the headset socket serves as the noise reduction MIC pickup hole to achieve the double microphone noise reduction function, and at the same time, the additional pickup hole does not require adding on the mobile phone shell, so that the processing difficulty of the mobile phone shell is reduced; the headset interface compatible with the microphone function does not weaken the dustproof and anti-static functions of the mobile phone, and is convenient in operation and suitable for all kinds of mobile phones.

Description

A kind of earphone interface of compatible microphone function

Technical field

The utility model relates to a kind of electronic product, particularly relates 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.Current 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, the mobile phone EMS memory 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 No.: 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, and the acting in conjunction by two MIC pickup hole internal circuits reaches decrease of noise functions.

In prior art, most mobile phones are to utilize said structure and in conjunction with related circuit, mobile phone is carried out to the noise abatement processing, 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 provide more passage for airborne dust and liquid suspension enter interior of mobile phone, thereby affect various performances and the useful life of mobile phone.

Summary of the invention

The purpose of this utility model 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, and earphone interface that again can compatible newly-increased microphone pickup.

The purpose of this utility model is 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 matching with continuant orifice near a side of earphone socket.

Described microphone is electret microphone or silicon micro-microphone.

The beneficial effects of the utility model are:

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 on hand set machine shell, not set up extra pickup hole, 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.

In figure, 1-printed circuit board, 2-earphone socket, 3-sealing device, 4-continuant orifice, 5-pickup hole, 6-microphone, 7-soft silica gel, 8-soft rubber, 9-housing, 10-silica gel, 11-earphone jack.

Embodiment

Below in conjunction with accompanying drawing, the technical solution of the utility model is described in further detail, but protection range of the present utility model 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, by soft silica gel 7 sealings for the wire hole of microphone, be provided with the soft rubber 8 that 1.5mm is thick in the periphery of microphone 6, be provided with the housing 9 that one deck 1mm is thick 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 be more than or equal to microphone 6 diameter 1/2.After being arranged on printed circuit board by sealing device 3, with silica gel 10, further seal, make a 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 matching with continuant orifice 4 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 utility model 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 to be independent of each other between the MIC1 of winner and noise reduction MIC, 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 for initiatively eliminating noise.Mike, by after collecting extraneous sound, after being processed, sends the sound wave contrary with noise, utilizes principle of cancellation to eliminate noise, i.e. after noise reduction MIC sampling, by after the waveform paraphase with the overlapping function that can realize noise reduction of microphone sampling.
