Abstract
The utility model relates to a Bluetooth earphone comprising a Bluetooth module 10, an antenna 11, a microphone 12 and a receiver 13. The utility model is characterized in that the antenna is connected to a radio frequency interface of the Bluetooth module through a radio frequency wire; the microphone and the receiver which are used for picking /playing audio signals are connected to a codec through an analog audio interface, wherein the codec can be integrated in the Bluetooth module; thereby, analog signals obtained by the conversion of the codec can be input or output. Owing to the structure, the utility model can be conveniently connected to a cell phone to realize the wireless earphone function and the utility model can also be connected to other Bluetooth audio gateway devices to transmit audio signals. The device has the advantages of small volume, portability and convenient use.
Description
Technical field
The utility model relates to Bluetooth wireless technology, specifically is a kind of earphone by the Bluetooth wireless technology transporting speech.
Technical background
Bluetooth (Bluetooth) is the short distance radio communication standards of being joined together to develop by mobile operator and mobile computing company, is used for designing setting up a kind of small-sized, economic, short-range Radio Link between portable computer, mobile phone and other mobile device.The frequency range of regulation and stipulation work is public ISM band, and peak data rate can reach 1Mbps.At present the extensive fields of bluetooth applications is exactly a mobile phone, can use the Bluetooth wireless technology transporting speech when making a phone call, the wireless connections of realization earphone and mobile phone.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of by the Bluetooth wireless technology transporting speech, realize the device of the wireless connections of earphone and mobile phone, this device has advantages such as the complex drive mechanism of need not, volume are little, easy to carry, easy to use.
The technical solution adopted in the utility model is such: promptly a kind of bluetooth earphone, comprise bluetooth module, antenna, microphone, receiver, it is characterized in that: antenna links to each other with the radio frequency interface of bluetooth module by radio frequency line, be used to pick up/microphone and the receiver of playing audio signal, also link to each other by analog audio interface and coding decoder or the coding decoder that is integrated in the bluetooth module, the analog signal that coding decoder is converted to inputs or outputs.
Said apparatus is realized wireless earphone function because described structure not only can link to each other with mobile phone easily, can also be connected transmitting audio signal with other Bluetooth audio frequency gateway devices.Device volume is little, easy to carry, easy to use.
