## Abstract

A wireless music transmission device for wirelessly controlling volume-adjustment and song-selection functions of iPod includes a wireless earphone and a wireless music transmitter. The wireless music transmitter is electrically connected to iPod. The wireless earphone and the wireless music transmitter both have a radio frequency integrated circuit, so as to transmit control signals of volume-adjustment and song-selection functions between wireless earphone and wireless music transmitter via radio frequency integrated circuits.

## Claims

### Claim 1

A wireless music transmission device for wirelessly controlling volume-adjustment and song-selection functions of iPod, comprising:
a wireless earphone, including a speaker unit, a volume-adjustment and song-selection unit, and a first radio frequency integrated circuit, the first radio frequency integrated circuit being electrically connected to the speaker unit and the volume-adjustment and song-selection unit; and
a wireless music transmitter, including a second radio frequency integrated circuit, a microprocessor, an analog/digital converter and a connection interface, the second radio frequency integrated circuit being electrically connected to the microprocessor and the analog/digital converter and wirelessly coupled to the first radio frequency integrated circuit, the wireless music transmitter being electrically connected to i-Pod through the connection interface, so as to control the volume-adjustment and song-selection functions of iPod via the wireless music transmitter and the wireless earphone.

### Claim 2 (depends on 1)

The wireless music transmission device of claim 1, wherein the first radio frequency integrated circuit of the wireless earphone transmits control signals in radio form to the second radio frequency integrated circuit of the wireless music transmitter.

### Claim 3 (depends on 2)

The wireless music transmission device of claim 2, wherein the control signals are provided to select songs and adjust volume.

### Claim 4 (depends on 2)

The wireless music transmission device of claim 2, wherein the first radio frequency integrated circuit of the wireless earphone transforms digital audio signals received from the second radio frequency integrated circuit of the wireless music transmitter into analog audio signals and transmits the analog audio signals to the speaker unit for playing.

### Claim 5 (depends on 1)

The wireless music transmission device of claim 1, wherein the second radio frequency integrated circuit of the wireless music transmitter transmits control signals received from the first radio frequency integrated circuit of the wireless earphone to the microprocessor for controlling the volume-adjustment and song-selection functions of iPod through the connection interface.

### Claim 6 (depends on 5)

The wireless music transmission device of claim 5, wherein the control signals are provided to select songs and adjust volume.

### Claim 7 (depends on 5)

The wireless music transmission device of claim 5, wherein the analog/digital converter of the wireless music transmitter transforms analog audio signals received from iPod into digital audio signals and transmits digital audio signals to the first radio frequency integrated circuit of the wireless earphone through the second radio frequency integrated circuit.

### Claim 8 (depends on 1)

The wireless music transmission device of claim 1, wherein the connection interface is an Universal Asynchronous Receiver/Transmitter interface.
