The technical solution of the utility model is:

Wireless vehicle mounted sound broadcasting device is characterized in that: (1) is made of onboard wireless radio receiver and phonetic synthesis broadcast device; (2) the phonetic synthesis broadcast device is made of main control module, memory device, usb data coffret, power module, keyboard, wireless transmitter module, main control module by USB host-host protocol module, document storage management module, public management module, phonetic synthesis module, music processing module, voice music output module, power management module, to press key processing module integrated.

The phonetic synthesis broadcast device is responsible for the content source that is stored in the device is converted to voice, and voice are sent to the FM radio receiver of vehicle audio by the mode of stereo radio (FM) emission.

The convertible content source of described phonetic synthesis module support comprises: the voice broadcast of the text (.txt) that support is downloaded from PC, word file (.doc), EMAIL.

Described usb data coffret is supported the USB1.1 Data Transport Protocol.

The storage file administration module is supported the Mass Storage of Microsoft file management protocol.

Described power module is supported the single battery pattern, and the input supply voltage scope is 1.0～1.5V.

Described keyboard is user key-press interface and key-press backlight read out instrument, and there are 3 buttons at the user key-press interface, be respectively play/stop, next/F.F., last one head/rewind down.

Described stereo radio FM transmitter module has three transmitting channels, can effectively avoid local radio station

Disturb.

Main control module is integrated by chip STMP1342L; Memory device is that capacity is the Flash storage chip K9F1G08 of 128MB; BA1404 is the chip of wireless transmitter module.

In the utility model, usb data coffret and USB host-host protocol module link, and power management module and power module link, and document storage management module and memory device link, keyboard and link by key processing module, the voice music output module connects wireless transmitter module.

STMP1342 mainly finishes usb data transmission, file management, phonetic synthesis and mp3 file and plays; K9F1G08 is that a capacity is the Flash memory device of 128MB, is mainly used to memory contents source and program code; Finish the stereo modulation and the emission work of sound.

Information speech broadcast device of the present utility model is the major part of native system, and following several function is arranged:

1, realize the conversion of Text To Speech;

2, the usb data coffret is provided;

3, support Mass Storage document storage management agreement;
