Abstract
The utility model relates to a mobile phone microphone device suitable for being used in a vehicle, which can be used for answering or calling by a mobile phone without being used for holding. Mainly comprises an output amplifier, a loudspeaker and a microphone which are connected with the output amplifier, and an input amplifier which is connected with the microphone. The output end of the input amplifier and the input end of the output amplifier are connected with a plug through wires, and the connecting plug is connected with the mobile phone. The device is fixed on the vehicle cigarette lighter through the plug-in terminal plug-in connection, and the microphone and the loudspeaker are close to a user, so that the device is convenient for making a call when a vehicle runs.
Description
The utility model relates to a kind of telephone device, relates to a kind of the need or rather and grips the mobile phone microphone apparatus that can answer or give orders or instructions with hand.
General mobile phone can cooperate loudspeaker to be plugged on the cigar lighter of vehicle, needn't grip receiver with hand and just answer and can emit the signal that mobile phone is answered by loudspeaker.But be difficult to accomplish in vehicle ' grip receiver simultaneously again with a hand push-button dialing, go to make a phone call if decontrol both hands, the driving that equals to stunt causes the danger of driving to increase greatly.
The purpose of this utility model is that the microphone apparatus to mobile phone makes improvements design, makes overall structure simple, and not needing to grip receiver with hand when using in vehicle can answer or give orders or instructions.
The utility model improves the mobile phone microphone apparatus of structure, comprise housing and be arranged on housing interior output amplifier and loud speaker thereof, the housing front end face is provided with the inserting terminal of pegging graft and connecting with the vehicle cigar lighter, the output amplifier input is drawn and is connected with attachment plug by lead from the housing rear end face, attachment plug connects mobile phone, it is characterized in that:
Also comprise by microphone and connect the originating circuit that the input amplifier input constitutes; The input amplifier output connects described attachment plug by described lead.
Described originating circuit is arranged in the described housing or independently is arranged in another housing.
Loud speaker, the equidistant user of microphone are very near, can utilize this device to use mobile phone directly to answer or give orders or instructions in vehicle.
Further specify technology of the present utility model below in conjunction with the embodiment accompanying drawing
The mobile phone microphone apparatus perspective view of Fig. 1, improvement structure.
One of mobile phone microphone apparatus electricity theory diagram of Fig. 2, improvement structure.
Two of the mobile phone microphone apparatus electricity theory diagram of Fig. 3, improvement structure.
The mobile phone microphone apparatus of Fig. 4, improvement structure is used connection diagram.
Referring to Fig. 1, Fig. 4, the mobile phone microphone apparatus before improving includes housing 3, lead 5 and attachment plug 32, is equiped with output amplifier 1 in the housing 3 and is attached thereto the loud speaker 2 that connects.The inserting terminal 31 of housing 3 front ends can be plugged on the cigar lighter 8 in the vehicle and fix, and the attachment plug 32 of housing 3 rear ends is plugged on the mobile phone 4 and is connected by the interior output amplifier 1 of lead 5 and housing, directly answers realizing.
This improvement structure is in the lead 5 between housing 3 and attachment plug 32, insert one and (can adopt telephone set speaking circuit sheet by input amplifier 61, as LS285A) originating circuit that connects and composes with microphone 62, this originating circuit can be installed in the housing 6, and (also can be installed in the housing 3) makes the lead 5 that connects output amplifier 1 input originally also connect the output of input amplifier 61 simultaneously.
Referring to Fig. 3, improve the mobile phone microphone apparatus of structure, its workflow of listening to circuit is: mobile phone 4 receives telephone signal; Telephone signal reaches output amplifier 1 through attachment plug 32, lead 5, the voice emplifying signal; The output of output amplifier 1 is connected with loud speaker 2, directly emits the voice signal that process is amplified by loud speaker 2.
Referring to Fig. 4, improve the mobile phone microphone apparatus of structure, the workflow of its originating circuit is: give orders or instructions facing to microphone 62 in mobile phone dialing back, the signal input microphone 62 of giving orders or instructions, microphone 62 connects the input of input amplifier 61, input amplifier 61 amplifies voice signal, and the voice signal after the amplification is delivered to mobile phone 4 through lead 5, attachment plug 32, is spread out of indirectly by mobile phone 4.
When the device of this improvement structure uses in installing, as shown in Figure 4, because the inserting terminal 31 of housing 3 is plugged on the interior cigar lighter 8 of car, mobile phone 4 then is installed on the handle 9 of user's side, therefore housing 3 is all very near from the user with mobile phone, the tape input amplifier of promptly being installed 61 and the housing 6 of microphone 62 are very near apart from the user, can realize the purpose of directly giving orders or instructions fully.
Device of the present utility model compared with wireless microphone be not difficult to find: wireless microphone is (wireless Microphone) need to there be transmitter and receiver also to link respectively and be installed on microphone and the mobile phone structure Complexity is apparent, and for transmitter and receiver are installed in respectively microphone and mobile phone In, the then internal structure of necessary corresponding adjustment microphone and mobile phone, thereby installation is also than trouble. This The device of utility model only needs to add microphone and input amplifier in wiring, and namely device itself has oneself Structure and do not affect other structures independently, but finished same function, not only reduced cost And be convenient to the user and reequip voluntarily extended function.
