Abstract

The invention provides Bluetooth hand-free navigation equipment which is connected with a first Bluetooth device and a second Bluetooth device in a Bluetooth manner. The first Bluetooth device sends first data and the second Bluetooth device sends second data. The Bluetooth hand-free navigation equipment comprises a Bluetooth module and a conversion module, wherein the Bluetooth module comprises a first transmission channel and a second transmission channel; by the first transmission channel, the first Bluetooth device inputs the first data into the Bluetooth module and the Bluetooth module outputs the second data to the first Bluetooth device; by the second transmission channel, the second Bluetooth device inputs the second data into the Bluetooth module and the Bluetooth module outputs the first data to the second Bluetooth device; the conversion module is connected with the Bluetooth module; and the conversion module transmits the first data from the first transmission channel to the second transmission channel and transmits the second data from the second transmission channel to the first transmission channel. A hearing effect of Bluetooth transmission cannot be influenced by noise in a vehicle; therefore, the Bluetooth hand-free navigation equipment is convenient for a driver to use.

Description

The bluetooth handsfree navigator

[technical field]

The present invention relates to a kind of bluetooth handsfree navigator, particularly a kind of bluetooth handsfree navigator of being convenient to driver's use.

[background technology]

In order in navigation, to realize the function of voice call; Usually can use mode as shown in Figure 1 to realize the bluetooth handsfree conversation at present on the portable navigation device (PND); Couple together through bluetooth betweenportable navigation device 10 and themobile phone 20; When voice were sent a telegram here,driver 30 conversed withloudspeaker 12 facing to themicrophone 11 ofportable navigation device 10.

But such design has following several shortcoming: under vehicle-mounted situation; Environment in the car can be more noisy; Need the position of manual adjustmentsportable navigation device 10 and the demand that volume adapts to conversation like this; Increaseddriver 30 use difficulty, certain influence has been arranged for safe driving; When driving motorcycle,driver 30 can not accomplish the action described in Fig. 1 basically.

[summary of the invention]

Main purpose of the present invention is to provide a kind of bluetooth handsfree navigator of the driver's of being convenient to use.

The present invention provides a kind of bluetooth handsfree navigator; Be connected with one first blue-tooth device and one second blue-tooth device bluetooth; Wherein, First blue-tooth device sends first data; And second blue-tooth device sends second data, and said bluetooth handsfree navigator comprises bluetooth module and modular converter, and said bluetooth module comprises first transmission channel and second transmission channel; Said first transmission channel is that first blue-tooth device is imported first data and exported second data through bluetooth module to first blue-tooth device to bluetooth module, and said second transmission channel is that second blue-tooth device is imported second data and exported first data through bluetooth module to second blue-tooth device to bluetooth module; Said modular converter connects said bluetooth module, and said modular converter transfers to second transmission channel with first data by first transmission channel, and second data are transferred to first transmission channel by second transmission channel.

Compared with prior art; All setting up bluetooth between bluetooth handsfree navigator of the present invention and first blue-tooth device and second blue-tooth device is connected; Sound can transfer to second blue-tooth device by first blue-tooth device after the bluetooth handsfree navigator; Also can after the bluetooth handsfree navigator, transfer to first blue-tooth device, to realize the two-way Bluetooth transmission between first blue-tooth device and second blue-tooth device, because of Bluetooth transmission can not influence auditory effect because of the internal car noise size by second blue-tooth device; Thereby avoid the operation of driver's manual adjustments portable navigation device volume, be convenient to driver's use.

[embodiment]

See also shown in Figure 2ly, the present invention provides a kind of bluetoothhandsfree navigator 50, is connected with one first blue-tooth device 60 and one second blue-tooth device, 70 bluetooths, and in present embodiment, said first blue-tooth device 60 is a bluetooth earphone; Said second blue-tooth device 70 is a bluetooth cellular phone.Wherein, First blue-tooth device 60 sends first data; And second blue-tooth device 70 sends second data; And said bluetoothhandsfree navigator 50 comprisesbluetooth module 51 andmodular converter 53; Saidbluetooth module 51 comprisesfirst transmission channel 511 andsecond transmission channel 512, and saidfirst transmission channel 511 is that first blue-tooth device 60 is also exported second data throughbluetooth module 51 to first blue-tooth device 60 tobluetooth module 51 inputs first data, and saidsecond transmission channel 512 is that second blue-tooth device 70 is imported second data and passed throughbluetooth module 51 to second blue-tooth device, 70 outputs, first data tobluetooth module 51; Saidmodular converter 53 connects saidbluetooth module 51, and saidmodular converter 53 transfers tosecond transmission channel 512 with first data byfirst transmission channel 511, and second data are transferred tofirst transmission channel 511 by second transmission channel 512.In present embodiment,bluetooth handsfree navigator 50 also comprisesformat converting module 54, and saidformat converting module 54 connectsbluetooth modules 51, and saidformat converting module 54 is in order to receive multi-media voice or navigation speech and with its conversion process; Said conversion process comprises sampling rate, bit rate, sound channel conversion.

All setting up bluetooth between bluetoothhandsfree navigator 50 of the present invention and first blue-tooth device 60 and second blue-tooth device 70 is connected; Sound can transfer to second blue-tooth device 70 by first blue-tooth device 60 after bluetoothhandsfree navigator 50; Also can after bluetoothhandsfree navigator 50, transfer to first blue-tooth device 60 by second blue-tooth device 70; To realize the two-way Bluetooth transmission between first blue-tooth device 60 and second blue-tooth device 70; Because of Bluetooth transmission can not influence auditory effect because of internal car noise is big or small, thereby avoid the operation of driver's manual adjustments PND volume, be convenient to driver's use.
