Title: Electromagnetic electroacoustic transducer
Inventor: MASUDA MITSUHIRO
IPC: H04R9/06
Filed: 2002-10-28
Abstract: <P>PROBLEM TO BE SOLVED: To improve frequency characteristics of an electromagnetic electroacoustic transducer by effectively using a resonance effect in a rear space of a diaphragm in the electromagnetic electroacoustic transducer.  <P>SOLUTION: The electromagnetic electroacoustic transducer is constituted by forming a first sound emission hole which communicates a front space of the diaphragm with an external space on the front side of a case which stores the diaphragm, a magnet and an electromagnetic coil and a second sound emission hole which communicates the rear space of the diaphragm with the external space on the front side of the case. In this case, resonant frequency Fv2 of the rear space of the diaphragm is set as a value within a range of F0<Fv2≤Fv1 to resonance frequency F0 of the diaphragm and resonant frequency Fv1 of the front space of the diaphragm. Thus, the frequency characteristics are made flat by improving drop of sound pressure in a frequency band between the resonance frequency F0 and the resonant frequency Fv1. In addition, the frequency characteristics are made flat by a superposing action of harmonic components of the resonant frequency Fv2 also in a frequency band lower than the resonance frequency F0.  <P>COPYRIGHT: (C)2004,JPO
