The power supply, Bluetooth RF circuit, audio input interface and the control button that are connected with described Bluetooth audio frequency circuit respectively.
Further, described Bluetooth voice frequency converter also comprises:
The audio input interface that is connected with described Bluetooth audio frequency circuit.
Further, described Bluetooth voice frequency converter also comprises:
The microphone interface that is connected with described Bluetooth audio frequency circuit.
Further, described control button comprises next bent function button, upper one bent function button and Bluetooth pairing switching function button.
Further, described power supply comprises rechargeable battery and power circuit.
The utility model is by being connected Bluetooth voice frequency converter with traditional wired audio amplifier, the wired audio amplifier of tradition can be converted to Baffle Box of Bluetooth, greatly reduce the manner that is embodied as of Baffle Box of Bluetooth, avoided the wasting of resources, and can be applied to vehicle-mounted audio device, the automobile that does not possess bluetooth equipment is low-cost, be upgraded to bluetooth equipment easily.
Description of drawings
Fig. 1 is the applied environment schematic diagram of the Bluetooth voice frequency converter that provides of the utility model;
Fig. 2 is the structure principle chart of the Bluetooth voice frequency converter that provides of the utility model.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
The utility model adopts Bluetooth voice frequency converter to be connected with traditional wired audio amplifier, and traditional wired audio amplifier is converted to Baffle Box of Bluetooth, makes traditional wired audio amplifier and different Bluetooth mobile equipment connection, and the transmission of data with play sound.
As shown in Figure 1, Bluetooth voice frequency converter 1 is connected by wired with traditional wired audio amplifier 2, can also be connected by audio output port wired and on the computer 3, be connected by the wireless mode pairing with bluetooth Mobile audio frequency equipment 4, like this, just can be implemented on the bluetooth Mobile audio frequency equipment 4 music play by Bluetooth wireless transmission to Bluetooth voice frequency converter 1, then Bluetooth voice frequency converter 1 receives data, convert the audio format signal to, be transferred to again traditional wired audio amplifier 2, sound amplifies audio signal through wired audio amplifier 2 original inner amplifying circuits, and plays out music.
When Bluetooth voice frequency converter 1 did not recognize attachable bluetooth Mobile audio frequency equipment 4, Bluetooth voice frequency converter 1 was in computer 3 and wired audio amplifier 2 direct-connected states all the time.Therefore, Bluetooth voice frequency converter 1 does not affect computer 3 with traditional occupation mode of wired audio amplifier 2, can reduce power consumption simultaneously yet, reaches energy-conservation purpose.
If Bluetooth voice frequency converter 1 connects with mobile phone, the interface of microphone is arranged on the Bluetooth voice frequency converter 1 simultaneously, the user just can be by the function of Bluetooth voice frequency converter 1 realization with the mobile phone phonetic conversation.
Fig. 2 shows the structural principle of Bluetooth voice frequency converter, for convenience of explanation, only shows the part relevant with the utility model.
Bluetooth voice frequency converter 1 comprises Bluetooth audio frequency circuit 11, and is connected the Bluetooth RF circuit 12 that is connected with Bluetooth audio frequency circuit 11, power supply 13, audio input interface 14 and control button 17.
Bluetooth voice frequency converter 1 is centered by Bluetooth audio frequency circuit 11, and 11 power supplies of 13 pairs of Bluetooth audio frequency circuit of power supply comprise rechargeable battery and power circuit, with movement and the portability of convenient wired audio amplifier 2.
As an embodiment of the present utility model, consider the application purpose of Bluetooth voice frequency converter 1, increased audio input interface 14 and audio output interface 15.
In addition, in order to make things convenient for being connected and conversation of Bluetooth voice frequency converter 1 and mobile phone, increase microphone interface 16 at Bluetooth voice frequency converter 1, to realize Bluetooth voice call.
After Bluetooth voice frequency converter 1 pairing connects bluetooth Mobile audio frequency equipment 4, bluetooth Mobile audio frequency equipment 4 transfers data to Bluetooth audio frequency circuit 11 by Bluetooth RF circuit 12, Bluetooth audio frequency circuit 11 is converted to audio signal by decoding, by audio output interface 15 outputs.
