Abstract: A base is integrally formed with a synthetic resin case by insert molding. A fixing portion of a core is engaged with a fixing hole of the base. An assembly jig is used to press the fixing portion to caulk the core to the base. The distance between a free end of the core and a diaphragm supporting portion of the case is guraranteed at a desired value.

Abstract: An electromagnetic electroacoustic transducer, includes: a diaphragm; a magnet; an electromagnetic coil; and a casing for storing the diaphragm, the magnet and the electromagnetic coil therein. The case has at least one first sound emitting hole through which a front space on a front surface of the diaphragm in the casing communicates with a front outer space infront of the casing and at least one second sound emitting hole through which a rear space on a rear surface of the diaphragm in the casing communicates with the front outer space in front of the casing. A resonant frequency Fv2 of the rear space is set at a value in the range: F0

Abstract: A core having a coil wound thereon is fixed to a base at the bottom. The base is fixed to a case made of synthetic resin by insert molding. A diaphragm is fixed to the case in circumference, and also a magnetic flux guide member is fixed to the case in circumference. Since the diaphragm and the magnetic flux guide member is commonly fixed to the case, no variation in the distance between the diaphragm and the magnetic flux guide member would occur for every product. Further, a gap L is formed between the magnet and the magnetic flux guide member, and an air hole is formed in the magnetic flux guide member. This improves the passage of air and reduces air dumper effect without modifying the magnet in shape.

Abstract: An electroacoustic transducer 1 is provided with a diaphragm 20 which is made of a magnetic material, and to which a magnetic piece 21 is fixed; a magnetic core 22 which is placed in proximity to the diaphragm 20; a coil 23 which supplies an oscillating magnetic field to the magnetic core 22; a housing 10 which accommodates the diaphragm 20, the magnetic core 22, and the coil 23, and which has a sound release opening 11 in a top plate opposed to the diaphragm 20, the sound release opening being larger than the magnetic piece 21. A beam portion 12 is formed integrally with the housing 10 which extends from a peripheral portion of the sound release opening 11 to another peripheral portion passing above the magnetic piece 21. A gap Ga between the diaphragm 20 and the magnetic core 22, and a gap Gb between the magnetic piece 21 and the beam portion 12 satisfy relationships of GanullGbnull5Ga.
