Embodiment
Below in conjunction with drawings and Examples, the utility model is described further.
Please refer to Fig. 1, the utility model embodiment provides a kind of wireless headphone system of strengthening the vehicle mounted communication privacy, comprise car-mounted terminal and a wireless headset, it is characterized in that: also comprise a switch, when described switch uses at described wireless headset, the audio output of car-mounted terminal is connected with the input of a radio frequency sending set; Described radio frequency sending set sends to described wireless headset by voice signal through modulation; When described switch does not use at described wireless headset, the audio output of car-mounted terminal is connected with internal loudspeaker.
Please refer to Fig. 2, radio frequency sending set described in figure is included as power circuit and the audio signal input circuit of this radio frequency sending set power supply; Described audio signal input circuit is connected with a radio-frequency antenna through signal modulation circuit, baseband circuit, radio-frequency transmissions circuit successively.It mainly realizes that the audio signal that will pass from car-mounted terminal is modulated at radio-frequency carrier, and goes out by antenna transmission.
Please refer to Fig. 3, the wireless headset described in figure is included as power circuit and the antenna of this wireless headset power supply; Described antenna is connected with earphone horn through radio-frequency transmitter, baseband circuit, audio signal demodulator, audio frequency output successively.It is mainly to accept the radiofrequency signal of being modulated by audio signal of being sent by radio frequency sending set, by the signal demodulation, delivers to earphone.
Please refer to Fig. 4, system of the present utility model also comprises that one for placing the earphone support of described wireless headset, described switch is arranged on described earphone support, also is provided with described wireless headset charging circuit and described radio frequency sending set circuit on described earphone support.It mainly realizes distributing from the audio signal of car-mounted terminal output according to the position of wireless headset, gives the wireless headset charging with radio-frequency transmitter, the operating state of giving radio frequency sending set Power supply and control transmitter: emission, dormancy and outage etc.Be noted that, the contour structures of earphone support described in the utility model is owing to being conventional structure, and can be according to user's hobby design, therefore, the utility model does not describe its profile in detail, its main technical point is that the interaction that can realize wireless headset and switch gets final product, and does not just elaborate here.
Can sum up, in the utility model preferred embodiment, its method and system is a switch of series winding between car-mounted terminal and internal loudspeaker.Switch is mounted in the support with the radio frequency receiver earphone.On off state is relevant to the position of earphone.Not requiring conversation privacy and non-talking state, is in the earphone support with the earphone of radio frequency receiver, and K switch 1 is normally off, and K switch 2 is normally opens, and voice signal is directly by car-mounted terminal, to be transferred to internal loudspeaker.When requiring privacy conversation to occur, leave the earphone support with the earphone of radio frequency receiver, K switch 1 becomes normally open, and K switch 2 be normally off, and cut-out is transferred to the voice signal of internal loudspeaker by car-mounted terminal.And voice signal is passed to a radio frequency sending set by car-mounted terminal.In transmitter, voice signal is modulated on radio-frequency carrier, from antenna, spreads out of.Earphone antenna receives the radio-frequency carrier of modulation, demodulation in radio-frequency transmitter, and restoring acoustical signal, and give earphone, thus realize the privacy conversation.
The foregoing is only preferred embodiment of the present utility model, all equalizations of doing according to the utility model claim change and modify, and all should belong to covering scope of the present utility model.
