High sound quality and Anti-dust, water etc.
As a acoustic speaker, a dynamic speaker using electromagnetic force (electrodynamic speaker) is used in many cases. In the dynamic speaker, as strong force is required, regarding a small speaker such as an earphone, in particular, the inertial force of the diaphragm is increased relatively, causing a problem of increased deviation between the electrical signal and the vibration. An electrostatic speaker has been used to solve the foregoing problem. However, in the conventional electrostatic speakers, one or a plurality of holes is required to be formed at each fixed electrode in order to transmit an acoustic wave generated by the vibration of the diaphragm to the outside.This causes a problem that dust, water, moisture, etc. are likely to come in. This invention solves mentioned problems by its new structure.

Company information
The revenue generated from technology transfer is reinvested into universities and researchers as new research funding, which is used to create further research outcomes. To ensure the smooth operation of this cycle, known as the "Intellectual Creation Cycle," we will actively promote technology transfer. The types of seeds we handle include patents, know-how, databases, and programs. We have established a collaborative framework by concluding basic technology transfer agreements with the following universities (as of June 1, 2025): - Tohoku University - Hirosaki University - Iwate University - Akita University - Fukushima University - Yamagata University - Tohoku Gakuin University - Iwate Medical University - Fukushima Medical University - Aizu University - Miyagi University - Hokkaido University - Muroran Institute of Technology - Showa Medical University
