Description

A kind of bluetooth receiver
Technical field
The utility model relates to the communications field, particularly a kind of bluetooth receiver.
Background technology
Our society is just moving towards the informationization of height, and in these epoch, the communication articles for use such as mobile phone, intercom, as making people not be subject to the restriction of when and where, carry out rapidly a kind of mobile communication terminal of information transmit-receive and voice transfer, are widely used.Above-mentioned embedded in mobile phone information transceiving device and speech recognition equipment, utilize this device reception information or transmit information to the other side, compared with wire communication terminal machine, be not more subject to the restriction of when and where, use more convenient.
As mentioned above, although the communication articles for use such as mobile phone, intercom are not subject to the restriction of when and where, use easily, modern still requires to utilize that the communication such as mobile phone, intercom articles for use can be conversed more easily, transmission information.Therefore just occurred that hand-free receiver, bluetooth the function such as exempt to listen, to meet the demand of user Geng Gao.
Summary of the invention
The bluetooth receiver that provides a kind of user to receive calls in the time that mobile phone inconvenience is answered is provided the purpose of this utility model.
The technical solution adopted in the utility model is:
A kind of bluetooth receiver, comprises microphone, speech conversion circuit, power amplifier, loudspeaker, Bluetooth chip, antenna, indicator light, button; Described antenna is electrically connected with Bluetooth chip, described button connects the input of Bluetooth chip by button drive circuit, described microphone connects the input of Bluetooth chip by speech conversion circuit, described loudspeaker connect the output of Bluetooth chip by power amplifier, described indicator light connects the output of Bluetooth chip by drive circuit of indicator, described Bluetooth chip connects a storage battery.Described storage battery is connected with a charging circuit, charging circuit external charger.
State indicator light and comprise incoming call indicator light and power supply indicator.
Described button comprise answer button, hang up button, volume increases button and volume reduces button.
Described charger is 5V charger.
The utility model adopts above technical scheme, utilize Bluetooth chip to coordinate microphone and loudspeaker to realize, the object of blue teeth wireless answering cell phone phone, indicator light is set points out in the time having incoming call, and can realize answering and the adjusting of volume of phone by button, this receiver is equipped with storage battery and corresponding charging circuit, has effectively ensured the power supply of receiver.
Brief description of the drawings
Below in conjunction with the drawings and specific embodiments, the utility model is described in further details;
Fig. 1 is schematic block circuit diagram of the present utility model.
Embodiment
As shown in Figure 1, a kind of bluetooth receiver, comprises microphone, speech conversion circuit, power amplifier, loudspeaker, Bluetooth chip, antenna, indicator light, button; Described antenna is electrically connected with Bluetooth chip, described button connects the input of Bluetooth chip by button drive circuit, described microphone connects the input of Bluetooth chip by speech conversion circuit, described loudspeaker connect the output of Bluetooth chip by power amplifier, described indicator light connects the output of Bluetooth chip by drive circuit of indicator, described Bluetooth chip connects a storage battery.Described storage battery is connected with a charging circuit, charging circuit external charger.
Described indicator light comprises incoming call indicator light and power supply indicator.
Described button comprise answer button, hang up button, volume increases button and volume reduces button.
Described charger is 5V charger.
After bluetooth receiver connects with mobile phone pairing, when mobile phone terminal has phone to call in, mobile phone sends instruction by bluetooth to bluetooth receiver, bluetooth receiver arrives the instruction from mobile phone by antenna reception, deliver to Bluetooth chip processing, after processing, Bluetooth chip is lighted and is extinguished by drive circuit of indicator control electricity indicator light after processing.User selects to answer or phone refusing by answering button and hanging up button on receiver.User is in the time receiving calls, and the audio signal of the phone that Bluetooth chip sends Bluetooth of mobile phone is delivered to power amplifier, and the audio signal that power amplifier provides Bluetooth chip is amplified rear drive sound horn.User can also increase button and volume minimizing button adjusting horn volume by volume in receiving calls.Receiver is in the time of call, and the sound that microphone recipient sends also becomes the signal of telecommunication to give Bluetooth chip by speech conversion circuit conversion, after being processed, sends to mobile phone terminal bluetooth through antenna by Bluetooth chip.Bluetooth receiver provides power supply support by storage battery.Storage battery connects charging circuit, provides constant charging current to charge a battery in the time that charging circuit is connected to 5V charger, and when storage battery is full of, charging circuit connects disconnection charge protection storage battery automatically.When cell voltage is during lower than predetermined voltage, Bluetooth chip control power supply indicator provides low electricity prompting.
The utility model utilizes Bluetooth chip to coordinate microphone and loudspeaker to realize the object of blue teeth wireless answering cell phone phone, indicator light is set points out in the time having incoming call, and can realize answering and the adjusting of volume of phone by button, this receiver is equipped with storage battery and corresponding charging circuit, has effectively ensured the power supply of receiver.
