Abstract
Disclosed is a GPS automobile navigation device, comprising a micro-processor, and a GPS navigation function unit, a display unit, an audio frequency input and output unit, and a power supply unit which are respectively connected with the micro-processor. The GPS automobile navigation device of the utility model is characterized in that the micro-processor is further bidirectionally connected with a radio transmit-receive unit whose output is transmitted to a wireless earphone; the wireless earphone comprises a micro-processor, and a power supply unit, a display unit, a radio transmit-receive unit and a keyboard which are connected with the micro-processor; the audio frequency input and output unit is bidirectionally connected with the radio transmit-receive unit; and the navigation device is further provided with a pedestal connected with the wireless earphone. The GPS automobile navigation device of the utility model utilizes a wireless earphone to carry out bidirectional wireless dialogue with the navigation device, thereby facilitating the operation. When the earphone is picked up, the audio frequency of the navigation device is automatically switched to the wireless earphone. The GPS automobile navigation device also ensures the confidentiality of the dialogue.
Description
Technical field
The utility model relates to a kind of automobile GPS navigation device, specifically refers to a kind of car navigation device with wireless headset.
Background technology
Current, it is more and more wider that GPS navigation equipment uses in automobile, but along with day by day the improving and uses the people of automobile to get more and more of life, more and more higher to the requirement of navigator.The now audio frequency output of the navigator on the market all is to listen by outer sound or with wired earphone, outer sound does not have confidentiality, wired earphone again can be very inconvenient when driving, these all bring inconvenience in the use to the user, can not satisfy when driving to require to navigate and realize easily the privacy conversation.
The utility model content
For the problems referred to above, the utility model provides a kind of GPS car navigation device, realizes the wireless communication function of earphone and navigator, plays again secret effect when bringing convenience to the user.The technical solution adopted in the utility model is: a kind of GPS car navigation device, comprise microprocessor, and the GPS navigation functional unit that is connected with microprocessor respectively, display unit, audio frequency input and output unit, power supply unit, it is characterized in that: the two-way transceiving unit that exports wireless headset to that is connected with also on the processor; State wireless headset and comprise microprocessor and the power supply unit that is connected with microprocessor, display unit, transceiving unit and keyboard, audio frequency input and output unit is connected with the transceiving unit is two-way.Also be provided with the base that is connected with wireless headset on the navigator.
The beneficial effects of the utility model are, carry out the double-direction radio dialogue by wireless headset and navigator, and easy to operate, when picking up earphone, the audio frequency of navigator automatically switches in the wireless headset, and the effect of secret telephony is arranged again.

Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
Figure 1A and Figure 1B are respectively the functional-block diagram of the utility model navigator and wireless headset.As shown in the figure, navigator mainly comprises microprocessor 11, microprocessor 11 input ports connect power supply unit 15 and keyboard 14, its output port connects audio frequency input-output unit 13, display unit 16 and other functional unit 18, its input/output port connects GPS functional unit 17, also is connected with simultaneously the transceiving unit 12 that exports wireless headset to.Described wireless earphone device microprocessor 21 input ports connect power supply unit 25 and keyboard 24, its output port connects display unit 26, its input/output port connects transceiving unit 22, transceiving unit and 23 two-way connections of audio frequency input and output unit.Described transceiving unit 12 and 22 is two-way radio module, can realize output and the input of voice.
The utility model principle of work is: after sending out keyboard 14, the task requests of this key is identified and processed to the microprocessor 11 of navigator, and this task can be transmitted to wireless earphone device by the transceiving unit 12 of navigator.Display unit on the navigator device 16 shows task requests simultaneously.In addition, when navigator has audio frequency output, the microprocessor 11 of navigator just can be transmitted to wireless earphone device by the transceiving unit 12 of navigator, the wireless transmit/receive units of wireless headset is realized opening and closing by the base that contacts that navigator and wireless headset are provided with itself, when not contacting, be that earphone is when being taken away, the transceiving unit of earphone begins to start immediately, the status indicator lamp of wireless earphone device display unit 26 is opened, and can also charge to wireless headset when wireless headset contacts with navigator simultaneously.
Be the schematic diagram of the utility model navigator device such as Fig. 2, SW1, SW2, SW3 forms the keyboard 14 of present embodiment, and SW1 is for pattern or definite operation, and SW2 and SW3 are as present embodiment display unit 16 for the operation LED1 of cursor move left and right and volume plus-minus and LED2, obviously, this display unit can realize with the LCD LCD MODULE, and wherein, LED2 is used for display radio earphone executing state.
J1 is two-way radio module 12.
J3 is the contact opening of navigator and wireless headset, i.e. the charging inlet of wireless headset.
J5 is GPS module 17
Be the circuit theory diagrams of the utility model wireless headset such as Fig. 3, SW1 and SW2 form the keyboard 24 of present embodiment, and SW1 and SW2 are the operations for the volume plus-minus.LED1 be wireless headset under off position, charging indication, LED2 is the indication of wireless headset duty.
J1 is two-way radio module 22.
J4 is the charging inlet of wireless headset.
