Abstract
The utility model discloses a device for converting a common earphone into a bluetooth earphone. The device comprises a machine shell and a machine core circuit which is arranged in the internal part of the machine shell. The panel of the machine shell of the device is provided with a power switch (1), a power/charging indication lamp (2) and a charging interface (3). One side surface of the machine shell of the device is provided with flattop 5pin USB earphone interface (4), a convex 5pin USB earphone interface (5) and a 4pin USB earphone interface (6). The other side surface of the machine shell of the device is provided with a 3.5mm earphone interface (7) used for a mobile phone with a microphone, a 3.5mm earphone interface (8) used for a computer, and a 2.5mm earphone interface (9). The device is provided with a bluetooth receiving module. After equipment powers on, bluetooth can be automatically turned on and connected by the mobile phone. Multiple mobile phone interfaces are arranged so that the earphones with multiple interfaces can be connected, and the bluetooth earphone can be obtained via combination. An audio amplification module is internally arranged so that an audio signal outputted by a bluetooth module can be amplified and then outputted to the multiple interfaces.
Description
Technical field
The utility model relates to mobile communication technology, particularly a kind of device that common headphones is converted into bluetooth earphone.
Background technology
Bluetooth is the radiotechnics of a kind of support equipment short haul connection (in general 10m).Can comprise mobile phone, PDA, wireless headset, notebook computer, be correlated with and carry out wireless messages exchange between numerous equipment such as peripheral hardware." bluetooth " technology of utilization, can simplify the communication between mobile communication terminal device effectively, also communicating by letter between simplified apparatus and internet Internet successfully, thus transfer of data is become more rapidly efficiently, be radio communication widening road.
Bluetooth earphone is applied in Bluetooth technology in hands-free headsets exactly, allows user can exempt impeding of irritating electric wire, comfortablely easily call in every way.Since bluetooth earphone comes out, it has been the good tool of Mobile Commerce family raising efficiency always.But bluetooth earphone is but expensive many than common earphone.People, in the time of bull's machine, have supporting Wiring type earphone, the audio of supporting earphone, call function are all relatively applicable to mobile phone, if but go out, when driving, wired earphone seems again to impede and stumbles.How a kind of device is provided, and this device is cheap compared with bluetooth earphone, can realize again bluetooth communication, and can apply fully the supporting earphone of mobile phone.
