Abstract
The utility model discloses an ear-hanging type digital interphone, comprising an interphone body capable of being hung on an ear. The interphone body is provided with a loudspeaker and a microphone thereon. The interphone body is internally provided with a main board, a lithium battery and an antenna. The main board integrates a sounder, a controller and a modem. The microphone collects sounds to be sampled and coded by the sounder and the controller, and then a signal is modulated by the modem and then emitted by the antenna. The antenna collects wireless signals to be modulated by the modem, and after the modulated signals are processed by the controller and the sounder, the loudspeaker plays voices. The ear-hanging type digital interphone adopts an integrated design, is light in weight, convenient to use and carry and easy to maintain, and internally adopts a digital signal processing technology combining the sounder, the controller and the modem, so that the product weight is light, the emission power is small, harm to health is avoided, and communication reliability and security are high as the digital technology is adopted to transmit wireless signals.
Description
Technical field
The utility model belongs to electronics technical field, is specifically related to a kind of supra-aural digital handset.
Background technology
At present, individual on the market carry with intercom be all portable interphone substantially, when call, need hand-held use, while call, hand-held or fixing ad-hoc location carries, as used rope band clip etc. to be fixed on waist, shoulder, arm.This intercom itself is comparatively heavy, carries inconvenience.Meanwhile, the noise of external environment condition also easily imports in call, causes in call noise larger.
Also there is the design of wearing by mode peripheral earphone modes such as wired, bluetooths, but it is unreliable that this mode connects, split-type design often all needs to operate again on earphone and intercom main frame, use complicated, earphone also easily damages and loses as accessory, on whole overall product, safeguards complicated and time consumption.
On market, also have in addition a kind of helmet-type for specific industry or wear-type customed product, the weight of this helmet own is just larger, can not wear continuously for a long time use, is also not suitable for extensive industry and uses.
Utility model content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, provide a kind of use easy to carry, converse clear, safeguard simple, wear supra-aural digital handset comfortable, aesthetic in appearance.
A kind of supra-aural digital handset, comprises the intercom body that can hang on ear, and described intercom body is provided with loud speaker and microphone, in described intercom body, is equipped with mainboard, lithium battery and antenna; On described mainboard, be integrated with vocoder, controller and modulator-demodulator, described microphone gathers sound, through vocoder, controller sample code, after modulator-demodulator modulation signal from antenna transmission; Antenna gathers wireless signal through modulator-demodulator restituted signal, and controller, vocoder signal are play voice by loud speaker after processing.
In described supra-aural digital handset, be also provided with the miniature physical interface for connecting external equipment.
In described supra-aural digital handset, be also provided with Wireless charging coil.
Described supra-aural digital handset is provided with function button group.
In described mainboard, be also integrated with wireless communication module.
The utility model adopts supra-aural integrated design, and product is light and handy, it is easy to carry to use, be easy to safeguard; Loudspeaker distance ear is very near, and lamprophonia is little to producing noise around; Microphone is convenient from mouth distance adjustment, introduces environmental noise little, and the voice of passing to the side of listening are more clear, has greatly reduced sound self-excitation simultaneously and has produced; The inner Digital Signal Processing that adopts vocoder, controller, modulator-demodulator combination, makes product very light and handy, and transmitting power is small, adopts digital technology transmitting wireless signals to healthy without harm simultaneously, and communication reliability confidentiality is very high.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is theory diagram of the present utility model.
Embodiment
Below in conjunction with specific embodiment, the utility model is described further.Should be understood that following examples are only for the utility model is described but not for limiting scope of the present utility model.
Embodiment 1
Referring to Fig. 1 and Fig. 2, a kind of supra-aural digital handset that the utility model provides, comprise the intercom body 1 that can hang on ear, the two ends of described intercom body 1 are respectively the loud speaker 2 of filling in earhole and the microphone 3 that is positioned at mouth place, in described intercom body 1, be equipped with mainboard 4, lithium battery 5 and antenna 6, on described mainboard 4, be integrated with vocoder 41, controller 42 and modulator-demodulator 43, described microphone 3 gathers sound, through vocoder 41, controller 42 sample codes, after modulator-demodulator 43 modulation signals, launch from antenna 6; Antenna 6 gathers wireless signal through modulator-demodulator 43 restituted signals, and controller 42, vocoder 41 signals are play voice by loud speaker 2 after processing, and described lithium battery 5 is for powering to mainboard 4, microphone 3 and loud speaker 2.
Embodiment 2
Described supra-aural digital handset also comprises miniature physical interface 7 and function button group 8, miniature physical interface 7, function button 8 can be arranged on the ear-hang arm of intercom body 1, also can be arranged on microphone or 3 loud speaker 2 shells, or arranged apart at different parts, also can adopt wireless technology be connected with ancillary equipment and do not arrange.
Lithium battery 5 can charge by miniature physical interface 7 connecting chargers, also can adopt the design that comprises Wireless charging coil 9 without miniature physical interface 7, now, is coordinated and is carried out wireless charging by Wireless charging coil 9.
Function button group 8 can be carried out the feature operations such as switch operating mode and volume adjusting.Mainboard 4 integrated after low coverage wireless communication module, also can connect outside appurtenances by radio communication arranges function, under this design, can not arrange function key, use miniature physical interface 7 line computers that intercom is configured and write frequently, circuit board integrated after low coverage wireless communication module, also can not need miniature physical interface 5 and directly use wireless mode to write frequently, microphone 3 gathers speech utterance, after internal module is processed by antenna 6 wireless signal emissions in the air.
The above is only preferred implementation of the present utility model, and protection range of the present utility model is also not only confined to above-described embodiment, and all technical schemes belonging under the utility model thinking all belong to protection range of the present utility model.It should be pointed out that for those skilled in the art, in the some improvements and modifications that do not depart under the utility model principle prerequisite, these improvements and modifications also should be considered as protection range of the present utility model.
