Abstract

A wireless digital music player has a support base, a portable storage device having digital music and audio data stored therein, and a player; the portable storage device and the player are fitted to the support base; the player has a control circuit capable of reading the music and audio data stored in the portable storage device, and has an emission circuit electrically connected to an output terminal of the control circuit for transmitting the music and audio data wirelessly at an intended frequency; thus, a radio can play the music and audio data after it is tuned to the same frequency as the emission circuit of the player to receive radio signals transmitted from the emission circuit.

Claims

1. A wireless digital music player, comprising

a support base;

a portable storage device fitted to the support base;

the portable storage device having digital music and audio data stored therein; and

a player fitted to the support base;

the player having a control circuit inside for reading the digital music and audio data stored in the portable storage device;

the player having a data socket electrically connected to the control circuit;

the player having a power supply circuit electrically connected to the control circuit for supplying power to the control circuit;

the player having an emission circuit electrically connected to an output terminal of the control circuit for transmitting the music and audio data wirelessly at an intended frequency;

the support base having a holding cavity for the player to be inserted therein;

the support base having a data plug in the holding cavity for the data socket of the player to be connected thereto;

the support base having a data socket electrically connected to the data plug thereof for the portable storage device to be connected thereto;

thereby being capable of making a radio play the music and audio data of the portable storage device after the radio is tuned to a same frequency as the emission circuit of the player to receive radio signals transmitted from the emission circuit.

2. The wireless digital music player as claimed in claim 1, wherein the portable storage device is a portable hard disk.

3. The wireless digital music player as claimed in claimed 1, wherein the portable storage device is a flash disk.

4.
