Description

Automobile hands-free device adapter

Technical field

The utility model relates to a kind of automobile hands-free device, particularly a kind of automobile hands-free device adapter.

Background technology

Because the generalization day by day that communication system uses, also impel vehicular telephone 3 to use universalness more, thereby the user is in order conveniently to use vehicular telephone 3 again based on the consideration of traffic safety on car, more than installing Handless 2 in the car additional, and commonly use adapter 1 with one and provide required power supply, and commonly use adapter 1 one side joints in this and be equipped with a microphone 2 and vehicular telephone 3 (seeing also shown in Figure 1) by automobile cigarette lighter 11;

But, general former times is only by the function of transferring with adapter 1, and for obtaining the output sound benefit of higher fax quality, then must in car body, be equipped with high-performance loudspeaker 12, yet, power is healed big loudspeaker 12 its relative volumes also more greatly, and add other attached outfits such as caller identification device and be arranged in the limited car body in general space, make in the car body the real no redundant space can ccontaining these optional equipments, and generally often unnecessary outfit is placed in instrument carrier panel upper limb 13 places and Windshield 14 formed spaces, so easily increase the dead angle of sight line on the contrary, and cause causing anxiety on the traffic safety, real do not see, and unnecessary distribution shuttles back and forth in wherein for we find pleasure in, more destroyed the car body overall appearance, and by being denounced by the user:

Commonly use adapter and have following deficiency:

1, when incoming call, the source of sound that then needs to cut off other earlier can be answered.

2, can't be absorbed in driving.

3, tool danger.

4, many distributions shuttle back and forth in car, destroy in the car attractive in appearance.

5, operation bothers.

6, do not have a progressive.

7, can't meet trend now.

8, take up space.

Hereat, how above-mentioned disappearance is forgone, be the place of the technical difficulties of this case creator institute desire solution.

In view of this, this case creator through the improvement that studies repeatedly, makes the utility model be born with professional attainment and technical concept that itself was possessed eventually.

Summary of the invention

Technical problem to be solved in the utility model is at the above-mentioned deficiency of prior art, and to provide a kind of easy to operate automobile hands-free device adapter that does not account for vehicle body space.

Above-mentioned technical matters of the present utility model is realized by following technology contents.

A kind of automobile hands-free device adapter is characterized in that: be provided with a hand-free communication apparatus, an acoustical equipment, a loudspeaker arrangement and a power supply device by a switch control unit in the car body internal interface, wherein:

This switch control unit is made up of a power on switch and an actuating switch, and this actuating switch is to connect to establish a loud speaker, but start this power on switch by power supply device, and when this handfree receiver unit produces the input source of sound, this switch control unit is by the sound equipment signal line, the sound equipment control signal that transmits a force disconnect order is to acoustical equipment, to intercept the source of sound that this acoustical equipment is produced, and should import source of sound by actuating switch and amplify via loudspeaker arrangement output, again when this Handless stops to produce the action of input source of sound, this switch control unit is to stop to transmit the sound equipment control signal of this force disconnect order to acoustical equipment, this moment, this acoustical equipment was the state that recovers original, so be to separate, improve the source of sound quality to reach with source of sound with acoustical equipment and hand-free communication apparatus.

Except that above-mentioned essential features, in specific implementation process, also can replenish following technology contents:

This switch control unit is made up of a plurality of relay, and the common pin of a plurality of relays is connected to winding displacement J2, and its normally closed contact is connected to winding displacement J3, and winding displacement J2 is connected in power on switch, and this winding displacement J3 is connected to acoustical equipment; This actuating switch is made up of crystal triode Q102 and Q101, is connect the loudspeaker arrangement of establishing with the pin of controlling winding displacement J1; Wherein external sound source input produces an electric current by MUTE sound equipment signal line and makes relay K 1, K2 and K3 inhale magnetic, and makes the 3 pin mutual conduction of winding displacement J2 and winding displacement J1, and the source of sound of the acoustical equipment of this winding displacement J3 is ended; And when external sound source stops to import, promptly work as this MUTE sound equipment signal line and stop received current, then the K1 of relay, K2 and K3 stop to inhale magnetic, establish the normally closed acoustical equipment continuation output source of sound that allows through a recovery closure and winding displacement J3 is connect.

This hand-free communication apparatus, a loudspeaker arrangement and a power supply device be common structure in car body, so can advance to reach easy to use, and do not account for the purpose of vehicle body space.

This hand-free communication apparatus is to be equipped with microphone and vehicular telephone.

The utility model is to utilize set sound source control circuit in this adapter, control this hands-free device employed opportunity, and when incoming call, need not to close earlier the trouble formality that sound equipment is answered again, and reach easy to operate, and it is to be established in car body inside, can advance to reach not account for the practical purpose of vehicle body space.

Advantage of the present utility model is:

1, its may command switching sound source, and need not to take great energy the source of sound of additionally closing other.

2, do not take up space.

3, easy and simple to handle.

4, tool safety.

5, tool progressive.

6, meet trend now.

7, tool practicality.

8, tool commercial competitiveness.

Be convenient and understand content of the present utility model, and the effect that can reach, conjunction with figs. is enumerated a specific embodiment now, introduction is described as follows in detail:
