Abstract

The present invention provides a car type MP3 sound converter that includes a case, within which is disposed a MP3 decoder, a frequency modulation transmitter module and a printed-circuit board constructed from related control circuits, wherein the printed-circuit board is further configured with a sound input jack, a sound output jack, a USB connector interface, a memory card connector and a related operating push button set. An electrical connection is made with the cigarette lighter connector on the case, thereby facilitating the car type MP3 sound converter to use a transmission interface of the USB connector interface or the memory card connector to acquire MP3 sound wave data stored in general storage media, whereafter the MP3 decoder implements decoding, and finally the decoded audio signals are transmitted through the frequency modulation transmitter module using a wireless method or are output through the sound output jack.

Claims
