Abstract
An electro-acoustic transducer includes: a housing, a partition member disposed inside the housing, a first electro-acoustic conversion unit, and a second electro-acoustic conversion unit. The first electro-acoustic conversion unit includes a fixed electrode, a vibrating membrane, and a support member that supports a partial region of the vibrating membrane and brings a part of the vibrating membrane in contact with the fixed electrode. 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 and a sound emitting part communicate with an acoustic outlet, and the partition member supports the support member and the support member.
