Title:
ELECTROACOUSTIC TRANSDUCER
Document Type and Number:
WIPO Patent Application WO/2020/158173
Kind Code:
A1
Abstract:
An electroacoustic transducer according to one embodiment of the present invention comprises a magnetic sound generator and a piezoelectric sound generator. The piezoelectric sound generator is connected so as to be driven in an opposite phase to the magnetic sound generator. Thus, it is possible to suppress a sound pressure dip in the vicinity of a crossover frequency even when the piezoelectric sound generator is of a relatively small diameter and improve acoustic characteristics.
