Abstract

A wiring structure is provided for an electroacoustic transducer directly converting digital signals from a single sound source to sound waves without conversion to analog signals. The structure includes a diaphragm, and a plurality of voice coils fixed to the diaphragm. The voice coils are connected to respective cables each consisting of a stranded pair of positive and negative input lines.

First claim

The invention claimed is:

1. A headphone for digital signal assembly comprising:
a pair of right and left ear pieces, each ear piece comprising a housing including an electroacoustic transducer having a diaphragm and a plurality of voice coils fixed to the diaphragm;
only one signal processing circuit, wherein the only one signal processing circuit is in only one of the right and left ear pieces;
a longitudinally curved head band having the right and left ear pieces at its ends; and
cables respectively connected to the voice coils,
wherein the respective cables consist of a positive input line and a negative input line,
wherein each positive input line and each negative input line connected to a same voice coil form a stranded pair,
wherein the cables are disposed inside or along the head band, and
wherein the cables are configured to transmit digital signals
i) from the only one signal processing circuit in one ear piece
ii) to the electroacoustic transducer in the other ear piece.

2. The headphone assembly according to claim 1 , wherein the cables each have an electromagnetic shielding structure covering the pair of positive and negative input signal lines.

3. The headphone assembly according to claim 1 , wherein the cables each have an electromagnetic shielding structure separately covering the positive input line and the negative input line of each cable.

4. The headphone assembly according to claim 1 , wherein all cables connected to the voice coil consists of a stranded pair of positive and negative input lines.
