Abstract
The utility model relates to a radio receiving connector device for mobile phones, which is used for switching the speech call sound of the mobile phone to radio receiving devices of a radio ear phone or an automobile vehicle radio, etc. The utility model comprises a mobile phone, a receiving connector, and a radio receiver. The utility model is suitable to various mobile phones and can hear the generated sound from a mobile phone receiver by means of the automobile radio, other radio receiving device, or the radio ear phone instead of moving the receiver of the mobile phone to the ear, which is convenient for receiving the phone when an automobile driver drives. The utility model is cheap in cost, low in electrical consumption, and convenient in operation.
Description
[technical field]
The utility model relates to a kind of mobile phone receiver sound conversion device, is used for the call of mobile phone is transformed into receiving systems such as wireless headset or automobile mounted broadcast receiver.
[background technology]
Similarly device has the mobile phone bluetooth earphone in the market, directly receives the wireless audio signal that mobile phone is launched, and is converted into the earphone voice signal.But this device only is applicable on the mobile phone of whole outfit Bluetooth technologies that present commercially available most mobile phones are inapplicable, and the mobile phone of applying Bluetooth involves great expense.
In recent years, above-mentioned shortcoming at Bluetooth technology, the technology that also has the wireless hand-free of similar mobile phone to answer is constantly come out, but these technology all are that the wireline audio signal is carried out the modulating/demodulating conversion, need thus to carry out wired connection with mobile phone, take the automobile cigarette lighter supply hub, and complex structure, technical difficulty are big, element cost height.
[utility model content]
The technical scheme that the utility model provides is to solve carries out sound conversion to various common mobile phones with wireless form, and simple in structure, cost is low, need not to take power supply around the automobile cigarette lighter supply hub etc.
The mobile phone wireless reciever device that the utility model is alleged, comprise a mobile phone, one answers a connector and a radio receiver, wherein answer the connector outside and be provided with a sound transducer (pick-up), when answering connector when being clamped on the mobile phone, the microphone of this pick-up is just in time aimed at the receiver of mobile phone, this is answered connector inside and also is provided with a circuit board, this circuit board comprises a modulation oscillator circuit and a signal oscillating amplifying circuit, the mobile phone receiver voice signal that sound transducer obtained is successively behind modulation oscillator circuit and signal oscillating amplifying circuit, convert radio signal to and send through antenna emission, receive by radio receiver with characteristic frequency.
The utility model radio receiver comprises inner casing, shell, switch, earplug, adjustment of inductance hole, antenna portals and built-in circuit board, its built-in circuit board with the specific radio wave signal that received through high frequency amplification, mixing, intermediate frequency amplification, frequency discrimination, low frequency amplify and power amplification after, be converted into voice signal through earphone speaker, received by the callee.This radio receiver also can be the vehicle-mounted radio on the automobile.
Advantage of the present utility model is, can be implemented in to need not when answering mobile phone the mobile phone receiver near ear, but utilize auto radio, other ANTENN AUDIO receiving systems or wireless headset can listen to the sound that the mobile phone receiver is sent.The utility model can be applicable to various mobile phones, the raw material and the components and parts that are adopted are cheap, the power consumptive province, conversation and stand-by time are long, easy to operate, be particularly suitable for the driver when driving a car safety, answer mobile phone easily, also can be used for occasions such as family or office.Wireless headset in the utility model also can guarantee the privacy conversed.

[embodiment]
Shown in figure one, utilize automobile mounted broadcast receiver to be as the execution mode of sound receiver:
Receiver position (1) with the wireless machine folder (11) of answering connector (6) of mobile phone is clamped mobile phone makes mobile phone receiver (1) near the wireless microphone (9) of answering connector of mobile phone.During conversation, open the wireless switch (10) of answering connector (8) of mobile phone, energized, behind the sound signal collecting that sound transducer (2) in the microphone (9) sends mobile phone receiver (1), zoom into radio frequency signals earlier through modulating oscillator (3), produce oscillator signal again, behind next stage oscillating circuit (4), carry out signal and amplify, will launch through antenna (5) through the signal after amplifying again.
Aforementioned oscillation signal frequency is adjusted into 88.7MHz or 106.5MHz can obtain the better sound effect.
With automobile mounted broadcast receiver be tuned to the frequency the same with aforementioned oscillation signal frequency, the broadcast receiver of searching for Automatic Frequency can stop when searching aforementioned oscillation signal frequency through antenna (5) emission automatically.Vehicle-mounted radio (7) can be converted to voice signal with wireless antenna (5) the institute emitted radio signal of answering in the connector (6) of mobile phone, and the loud speaker by automobile mounted broadcast receiver (7) spreads out of.
Shown in figure two, utilize wireless headset to be as the execution mode of sound receiver:
The machine folder (11) of mobile phone wireless connector is clamped mobile phone receiver position (1), make the microphone (9) of mobile phone receiver (1) near the mobile phone wireless connector.During conversation, open the switch (10) of mobile phone wireless connector (8), energized, behind the sound signal collecting that sound transducer (2) in the microphone (9) sends mobile phone receiver (1), zoom into radio frequency signals earlier, produce oscillator signal again through modulating oscillator (3), behind next stage oscillating circuit (4), carry out signal and amplify, will launch through antenna (5) through the signal after amplifying again.
The receive frequency of wireless headset is set at consistent with aforementioned oscillator signal in advance, and can finely tune by adjustment of inductance hole (15).During conversation, open wireless headset switch (13), the antenna of wireless headset receive aforementioned antenna institute emitted radio signal through 9088 integrated circuit high frequency amplifications, mixing, intermediate frequency amplification, frequency discrimination, low frequency amplify and power amplification after, be converted into voice signal through earphone speaker.
