Electro-acoustic transducer

An electro-acoustic transducer comprising:

• a housing that includes an acoustic outlet for emitting a sound to the outside;
• a partition member disposed inside the housing;
• a first electro-acoustic conversion unit disposed inside the housing;
• and
• a second electro-acoustic conversion unit disposed inside the housing, wherein the first electro-acoustic conversion unit and the second electro-acoustic conversion unit each include:
• a fixed electrode;
• a vibrating membrane which is disposed opposite to the fixed electrode and vibrates in accordance with a potential difference generated between the fixed electrode and the vibrating membrane, on the basis of an electrical signal;
• and
• a support member that supports a partial region of the vibrating membrane and brings a part of the vibrating membrane into contact with the fixed electrode,
• wherein a distance between the vibrating membrane and the fixed electrode in a thickness direction of the fixed electrode becomes longer as the distance from the partial region to an outer side increases,
• wherein the first electro-acoustic conversion unit and the second electro-acoustic conversion unit are disposed facing each other across the partition member so that a sound emitting part of the first electro-acoustic conversion unit and a sound emitting part of the second electro-acoustic conversion unit communicate with the acoustic outlet, and
• the partition member supports the support member of the first electro-acoustic conversion unit and the support member of the second electro-acoustic conversion unit.
