Abstract
The utility model discloses a kind of onboard wireless radio frequency earphone system, comprise signal adapter, controller, selector switch, power amplifier module, radio-frequency signal generator, radio-frequency transmissions antenna, radio frequency earphone and earphone support.In-car entertainment system is by output audio signal access less radio-frequency earphone system after mobile phone signal, reception signals, multimedia signal dispose, less radio-frequency earphone system is by Audio Signal Processing, then selector switch is entered, one tunnel connects loudspeaker after power amplifier module, another road connects radio-frequency antenna and launches after radio-frequency signal generator, is received by radio frequency earphone.The utility model is connected between original vehicle entertainment system and loudspeaker, when radio frequency earphone is placed on earphone support, loudspeaker is automatically selected to play sound, when radio frequency earphone leaves earphone support, automatic selection radio frequency earphone sound reproduction sound, facilitates occupant and uses.
Description
Technical field
The utility model relates to a kind of earphone system, and specifically a kind of onboard wireless radio frequency earphone system, belongs to vehicle electronics field.
Background technology
Along with popularizing of family-sized car, people obviously increase the time in car, and in car, call is inevitable.In order to traffic safety, bluetooth handsfree call is a good solution, and therefore on-vehicle Bluetooth system obtains significant progress.But often drive for some but the user of preference earphone, bluetooth earphone is not a perfect solution.Because Bluetooth communication is point-to-point communication protocol, can not realize point-to-multipoint communication, namely a bluetooth earphone can not be multiple speech ciphering equipment services simultaneously, can not meet the compatibility requirement of radio in car, apparatus for media playing and mobile phone communication.Vehicle entertainment system current in addition does not all have the Handfree agreement of Supporting connectivity bluetooth earphone, does not realize connection bluetooth earphone function.
Summary of the invention
For above-mentioned prior art Problems existing, the utility model provides a kind of onboard wireless radio frequency earphone system, and this onboard wireless radio frequency earphone system can realize wireless headset by vehicle entertainment system and receive calls, and listens to radio and multimedia.
For achieving the above object, a kind of onboard wireless radio frequency of the utility model earphone system, comprises signal adapter, controller, power amplifier module, radio-frequency signal generator, radio frequency earphone, radio-frequency transmissions antenna, selector switch and earphone support; The sealing of described signal adapter, controller, power amplifier module, radio-frequency signal generator, radio-frequency transmissions antenna, selector switch is arranged on earphone base inner, and radio frequency earphone is placed on earphone support, and its outer shape is mated with earphone support; Earphone support arranges contact switch; Contact switch connects controller.
Audio signal through signal adapter process laggard enter selector switch, a road through power amplifier module amplify after connect loudspeaker, another road forms radiofrequency signal through radio-frequency signal generator, is sent by radio-frequency antenna, is received by radio frequency earphone.
Controller triggers by KL.15 ignition signal, control signal converter, selector switch, power amplifier module, radio-frequency signal generator radio-frequency transmissions antenna and radio frequency earphone.
Radio frequency earphone controls the break-make of contact switch when being placed in earphone support.
The utility model onboard wireless radio frequency earphone system structure is simple, easy to operate.This system, by integrated to Vehicular media player, radio and mobile phone signal, automatically selected sound source, is automatically selected player, makes user in enjoyment media music or while listening to transport information, does not delay and receive mobile communication information.
Accompanying drawing explanation
Fig. 1 is the utility model structure composition schematic diagram;
Fig. 2 is that the utility model signal moves towards schematic diagram.
Detailed description of the invention
Below in conjunction with detailed description of the invention, the utility model is further illustrated:
A kind of onboard wireless radio frequency earphone system, comprises signal adapter, controller, power amplifier module, radio-frequency signal generator, radio frequency earphone, radio-frequency transmissions antenna, selector switch and earphone support; The sealing of described signal adapter, controller, power amplifier module, radio-frequency signal generator, radio-frequency transmissions antenna, selector switch is arranged on earphone base inner, and radio frequency earphone is placed on earphone support, and its outer shape is mated with earphone support; Earphone support arranges contact switch; Contact switch connects controller.
Audio signal through signal adapter process laggard enter selector switch, a road through power amplifier module amplify after connect loudspeaker, another road forms radiofrequency signal through radio-frequency signal generator, is sent by radio-frequency antenna, is received by radio frequency earphone.
Controller triggers by KL.15 ignition signal, control signal converter, selector switch, power amplifier module, radio-frequency signal generator radio-frequency transmissions antenna and radio frequency earphone.
Radio frequency earphone controls the break-make of contact switch when being placed in earphone support.
During use, automotive ignition, vehicle entertainment system is opened, and less radio-frequency earphone system is also opened thereupon.When radio frequency earphone is placed on earphone support, contact switch turns on/off, and controller controls selector switch, automatically selects loudspeaker to play sound; When radio frequency earphone takes off from earphone support by user of service, contact switch disconnects/connects, and controller controls selector switch, and selector switch selects radio frequency earphone to play sound automatically.
Radio frequency earphone adopts the transmission frequency of 2.4GHz, and this band transmissions is stablized, and antijamming capability is strong, and receiving range can reach about 10 meters, can meet the instructions for use of all users in car.Radio frequency earphone has volume knob, can control volume.
Described earphone support is provided with volume control switch, makes to regulate volume convenient.
Earphone support is arranged earphone charging inlet, when earphone is placed in earphone support, charging inlet connects radio frequency earphone simultaneously and charges.
