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 analogue 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

1 . A wiring structure for an electroacoustic transducer for digital signal comprising:
a diaphragm; a plurality of voice coils fixed to the diaphragm; and cables respectively connected to the voice coils, the cables each consisting of a stranded pair of positive and negative input lines.

2 . The wiring structure according to claim 1 , wherein the cables each have an electromagnetic shielding structure comprising a net member covering the pair of positive and negative input lines.

3 . The wiring structure according to claim 1 , wherein the cables each have an electromagnetic shielding structure comprising a conductive tube covering the pair of positive and negative input lines.

4 . The wiring structure according to claim 1 , wherein the cables each have an electromagnetic shielding structure comprising net members separately covering the positive input line and the negative input line of each cable.

5 . The wiring structure according to claim 1 , wherein the cables each have an electromagnetic shielding structure comprising conductive tubes separately covering the positive input line and the negative input line of each cable.

6 . The wiring structure according to claim 1 , wherein digital signals having different signal sequences are generated from a single sound source signal and are applied to the respective voice coils.

7 . A headphone for digital signal assembly comprising:
a pair of right and left ear pieces each comprising a housing including an electroacoustic transducer having a diaphragm and a plurality of voice coils fixed to the diaphragm; and a longitudinally curved head band having the right and left ear pieces at its ends, wherein the voice coils are connected to respective cables each consisting of a stranded pair of positive and negative input lines.

8 . The headphone assembly according to claim 7 , wherein the cables each have an electromagnetic shielding structure covering the pair of positive and negative input signal lines.

9 . The headphone assembly according to claim 7 , wherein the cables each have an electromagnetic shielding structure separately covering the positive input line and the negative input line of each cable.
