Abstract
The utility model relates to a bluetooth headset, which comprises a bluetooth module, a bluetooth antenna, a radio frequency power amplifier and low noise amplifier module and a radio frequency switch, wherein the radio frequency power amplifier and low noise amplifier module and the radio frequency switch are connected with the bluetooth module, the radio frequency power amplifier and low noise amplifier module is connected with the radio frequency switch, and the radio frequency power amplifier and low noise amplifier module is connected with the bluetooth antenna. By adopting the structure, the bluetooth headset has a talkback function and can realize a talkback in places which are not covered by a mobile network.
Description
Technical field:
The utility model relates to communication field, specifically is a bluetooth earphone.
Background technology:
In today of mobile communication technology fast development, the use of Bluetooth technology also more and more widely, bluetooth earphone makes people break away from the constraint of wired earphone, the both hands of also having liberated the user simultaneously.But at present, the bluetooth earphone function is simple, can only realize wireless earphone function with the mobile phone pairing with Bluetooth function.If intercommunication can only realize vacation " intercommunication " by mobile phone dialing the other side phone number, and the restriction that covered by the mobile phone mobile network, in the place that does not have the mobile network to cover, mobile phone does not have signal, just can not realize intercommunication at all yet.
The utility model content:
The technical problems to be solved in the utility model is, overcomes existing technological deficiency, and a kind of bluetooth earphone that has intercommunication function and also can intercommunication in the place that does not have the mobile network to cover is provided.
Technical solution of the present utility model is, a kind of bluetooth earphone is provided, it comprises bluetooth module, Bluetooth antenna, it also comprises radio-frequency (RF) power amplification and low noise amplifier module, radio-frequency (RF) switch, described radio-frequency (RF) power amplification is connected with bluetooth module with radio-frequency (RF) switch with low noise amplifier module, described radio-frequency (RF) power amplification is connected with radio-frequency (RF) switch with low noise amplifier module, and described Bluetooth antenna is connected with low noise amplifier module with radio-frequency (RF) power amplification.
After adopting said structure, the utlity model has following advantage:
The utility model has increased radio-frequency (RF) power amplification and low noise amplifier module and radio-frequency (RF) switch on bluetooth module commonly used, increased the transmitting power of bluetooth, improved the sensitivity that receives, thereby can realize the real bluetooth intercommunication of (as 100 meters) in the certain limit, greatly facilitate the both sides member who needs intercommunication like this, and in the place that does not have the mobile network to cover (as the mountain area), both sides also can link up freely by intercommunication function.
Description of drawings:
Accompanying drawing is the functional-block diagram of the utility model bluetooth earphone;
Embodiment:
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
As shown in the figure, the utility model provides a kind of bluetooth earphone, it comprises bluetooth module, Bluetooth antenna, it also comprises radio-frequency (RF) power amplification and low noise amplifier module, radio-frequency (RF) switch, described radio-frequency (RF) power amplification is connected with bluetooth module with radio-frequency (RF) switch with low noise amplifier module, described radio-frequency (RF) power amplification is connected with radio-frequency (RF) switch with low noise amplifier module, and described Bluetooth antenna is connected with low noise amplifier module with radio-frequency (RF) power amplification.Described bluetooth module is the commercially available prod, and in the present embodiment, the model of employing is FW3303, is used for realizing Bluetooth transmission protocol, the audio frequency echo that disappears, noise suppressed, the processing of audio frequency aspects such as audio frequency amplification and man-machine interface control; The model that described radio-frequency (RF) power amplification and low noise amplifier module adopt is RDAT212, is used for realizing that the power amplification of Bluetooth transmission part and the low noise of receiving unit amplify; The model that described radio-frequency (RF) switch adopts is HWS408, is used for realizing the transmitting-receiving switching of Bluetooth RF.The model of described Bluetooth antenna is the PIFI antenna, is used for realizing the spatial emission and the reception of Bluetooth RF signal.
Operation principle of the present utility model is: utilize radio-frequency (RF) power amplification and low noise amplifier module and radio-frequency (RF) switch, increase Bluetooth transmission power and improve receiving sensitivity, and on bluetooth module, realize Bluetooth transmission protocol, audio frequency disappear echo and noise suppression algorithm, audio frequency output is amplified and microphone is imported Audio Processing such as amplification, finish the control of man-machine interface simultaneously and, on original bluetooth module, increase remote intercommunication function by software algorithm and agreement to the control of radio-frequency (RF) power amplification and low noise amplifier (RDAT212) and radio-frequency (RF) switch (HWS408).
During intercommunication, behind the microphone voice signal process noise reduction and pin echo processing of bluetooth module (FW3303) with local terminal, launch, received by the opposite end then via radio-frequency (RF) switch (HWS408), radio-frequency (RF) power amplification (RDAT212) and antenna; In the opposite end, after antenna receives this signal, pass to bluetooth module (FW3303) through radio-frequency (RF) power amplification (RDAT212) and radio-frequency (RF) switch (HWS408), bluetooth module is sent out from the loudspeaker of local terminal after it is done speech processes.So flow process realizes intercommunication.
Certainly; above-mentioned explanation is not to be limit value to essential scope of the present utility model; the utility model also is not limited in above-mentioned giving an example; the variation that those skilled in the art person has done in essential scope of the present utility model, remodeling, interpolation or replacement also should belong to protection range of the present utility model.
