Abstract
An electroacoustic transducer includes a diaphragm, a diaphragm support connected to a part of the diaphragm in a direction of vibration of the diaphragm, a driver connected to the diaphragm support to vibrate the diaphragm, a driver support connected to the driver opposite to the diaphragm to support a part of the driver, a base connected to the driver support and having a larger area than the diaphragm, and a frame connected to the base from a same side as the driver support and disposed within a gap between an outside of the diaphragm and an outside of the driver.
Claims19
An electroacoustic transducer comprising:
- a diaphragm;
- a diaphragm support connected to a part of the diaphragm in a direction of vibration of the diaphragm;
- a driver connected to the diaphragm support and configured to vibrate the diaphragm;
- a driver support connected to the driver opposite to the diaphragm and configured to support a part of the driver;
- a base connected to the driver support and having a larger area than the diaphragm;
- a frame connected to the base from a same side as the driver support and disposed with a gap between an outside of the diaphragm and an outside of the driver.
A method of manufacturing electroacoustic transducer comprising:
- a first step forming a first structure including a diaphragm, a diaphragm support, a first frame, and a beam, wherein:
- the diaphragm support is connected to a part of the diaphragm in a direction of vibration of the diaphragm;
- and
- the first frame surrounds an outer circumference of the diaphragm and second frame surrounds an outer circumference of the driver;
- and
- the beam connects the diaphragm and the first layer,
- a second step forming a second structure which includes a driver, a driver support, and a second frame, wherein:
- the driver vibrates the diaphragm;
- and
- the driver support supports a part of the driver;
- and
- a base connected to the driver support and having a larger area than the diaphragm;
- and
- the second frame which surrounds the outer circumference of the driver,
- a third step connecting the first structure and the second structure,
- a fourth step removing or breaking the beam, wherein:
- the first frame is disposed with a gap between the outer circumference of the diaphragm and the outer circumference of the driver.
