In sum, prior art utilizes bluetooth earphone that there is the problem that battery module need charge and service time is limited and part-structure is unnecessary in traditional sound equipment wireless penetration transformation as can be known, therefore is necessary to propose improved technological means in fact, solves this problem.
The utility model content
Utilize bluetooth earphone that there is the problem that battery module need charge and service time is limited and part-structure is unnecessary in traditional sound equipment wireless penetration transformation for overcoming above-mentioned prior art, main purpose of the present utility model is to provide a kind of Bluetooth audio frequency transducer, and it can realize the wireless penetration of traditional sound equipment is controlled by simple structure, cheap cost.
For reaching above-mentioned and other purpose, a kind of Bluetooth audio frequency transducer of the utility model, at least comprise: Bluetooth circuit and the antenna that is connected with described Bluetooth circuit, audio interface and power supply interface, described audio interface is connected with outer audio equipment, and described power supply interface is connected with power supply.
Preferably, described Bluetooth circuit is connected with described audio interface by audio transmission line.
Further, described audio interface is the standard audio interface, with the supporting use of the audio connecting cord of described outer audio equipment.
Further, described audio interface is male or female.
Preferably, described Bluetooth circuit links to each other with described power supply interface by a USB connecting line, and described power supply interface is used for being connected with supply socket.
Further, described power supply interface is a USB interface, directly connects low-voltage dc voltage.
Further, described power supply interface is connected with USB interface on the described outer audio equipment.
Preferably, described Bluetooth audio frequency transducer also comprises a voltage transformation module, is connected between described power supply interface and the described Bluetooth circuit, with when described power supply interface is connected with external ac power source, will export to described Bluetooth circuit after the alternating voltage transformation.
Compared with prior art, a kind of Bluetooth audio frequency transducer of the utility model make the Bluetooth audio frequency converter inside not need storage battery, and service time is long by power supply interface is set; Simultaneously, audio interface form of the present utility model is multiple, can satisfy the demand of each electric appliances or sound equipment.
