Abstract

The invention provides a vibrating diaphragm and an electroacoustic transducer capable of suppressing the influence on the lowest resonant frequency and improving the mechanical strength. The invention relates to a vibrating diaphragm (144A). The present invention is provided with: a main diaphragm (1441); a sub-diaphragm (1442) connected to the outer periphery of the main diaphragm (1441); a reinforcing material (1446A) disposed on the boundary between the main diaphragm (1441) and the sub-diaphragm (1442); and the outer periphery of the sub-diaphragm (1442) is disposed so that the range of the reinforcing material (1446A) does not extend.

Description

technical field [0001] The invention relates to a diaphragm and an electroacoustic transducer. Background technique [0002] Electroacoustic transducers that convert electrical signals and sound waves to each other are installed in electroacoustic transducers such as headphones, microphones, and speakers. The electroacoustic transducer is vibrated by a diaphragm based on an electrical signal to generate a sound wave corresponding to the electric signal, or by a diaphragm vibrated based on a sound wave to generate an electrical signal corresponding to the sound wave. [0003] The conversion types of electro-acoustic transducers include dynamic type using magnetic field and capacitive type using electric field. [0004] The dynamic electro-acoustic transducer has a magnetic circuit, a voice coil, and a diaphragm. The magnetic circuit generates a magnetic field. The voice coil is a conductor arranged in the magnetic field of the magnetic circuit, and is installed on the diap...
