Title:
ELECTROACOUSTIC TRANSDUCER AND UNIT FOR ELECTROACOUSTIC TRANSDUCER
Document Type and Number:
Japanese Patent JP2022160797
Kind Code:
A
Abstract:
To obtain an electroacoustic transducer and a unit for the electroacoustic transducer capable of reproducing high-quality sound by improving the reduction in sound pressure in an intermediate frequency band between low and high frequencies while achieving miniaturization.SOLUTION: An electroacoustic transducer 10 is provided with a port 36 leading the frequency band component of at least a part of sound radiated from a first diaphragm 28 in the direction opposite to a direction in which the front face 38A of a second diaphragm 38 faces to an external space S1 on the front face 38A side of the second diaphragm 38. The electroacoustic transducer 10 is provided with the port 36 so as to be configured such that the sound pressure of a synthesized sound in the vicinity of a crossover frequency of the sound radiated from the first diaphragm 28 and the second diaphragm 38 when a drive unit 16 generates vibration is the sound pressure or more at the crossover frequency of sound radiated from only one of the first diaphragm 28 and the second diaphragm 38.SELECTED DRAWING: Figure 1
