Problems solved by technology

However, this unrestrained performance of electrostatic speakers can cause another problem, that is, the electrodes and vibrators can easily deviate from their position setting (positioning)

Embodiment Construction

[0031] The invention is described in more detail by way of example with reference to the accompanying drawings.

[0032] figure 1 The appearance of the electrostatic speaker 1 according to the preferred embodiment of the present invention is schematically shown. FIG. 2 shows the electronic configuration and cross-sectional configuration of the electrostatic speaker 1 .

[0033] The electrostatic speaker 1 includes a vibrator 10 , conductive cloths 20U and 20L, elastic members 30U and 30L, and a string 40 . In the embodiment of the present invention, both the conductive cloths 20U and 20L have the same constitution, and both the elastic members 30U and 30L have the same constitution. For convenience, both reference numerals 20U and 20L are denoted by the same reference numeral "20", and both reference numerals 30U and 30L are denoted by the same reference numeral "30". In order to simplify the display in a visual and easy-to-grasp manner, the aforementioned constituent elem...

Abstract

An electrostatic speaker is constituted of a vibrator, conductive cloths, and elastic members, which are laminated together and woven together using strings. Since all the constituent elements are restrained in positioning by strings, the overall structure thereof is not substantially changed even when the electrostatic speaker is deformed in shape by bending or curving, wherein it is possible to secure the prescribed positional relationship between the constituent elements, which are not deviated in positioning. It is possible to introduce a sheet composed of a thermoplastic resin, which holds the vibrator and elastic members therein. The conductive cloths can be replaced with film electrodes, each of which is formed such that a conductive polymer layer is formed on a base film composed of a thermoplastic resin.

Description

technical field [0001] The present invention relates to an electrostatic speaker in which a vibrator held between opposing electrodes vibrates in response to an audio signal to generate sound. [0002] This application claims priority from Japanese Patent Application No. 2007-251158 and Japanese Patent Application No. 2008-132235; the entire contents of both applications are hereby incorporated by reference. Background technique [0003] The electrostatic speaker includes opposing electrodes that are spaced apart from each other at a predetermined distance and hold a plate-shaped vibrator (or vibrating member) having conductive properties therebetween. Due to a change in voltage applied between opposing electrodes in an electrostatic speaker to which the vibrator is supplied with a bias voltage, an electrostatic force applied to the vibrator changes to cause the vibrator to displace. Displacement occurs repeatedly in the vibrator due to a change in applied voltage in respon...
