    摘要： In the surface-mounted electromagnetic sound generating body in which a thin resin casing incorporating a sound generating unit is formed with a sound release hole, a sound leakage prevention member separate from the casing is provided around the sound release hole. This arrangement reduces the number of processes for assembling the surface-mounted electromagnetic sound generating body in the manufacture of a mobile phone and at the same time minimizes the volume occupied by the surface-mounted electromagnetic sound generating body on a printed circuit board.

    摘要： The invention provides an electroacoustic transducer wherein the resonant chamber is given a space and volume necessary for resonance and the vibration system is given an efficient air damping effect and thereby undesired vibrations are suppressed with the resonant effect maintained. The electroacoustic transducer according to the invention is provided with a resonant chamber for resonating with the vibration of a diaphragm and a sound ejecting hole for communicating the resonant chamber with the outside air formed on a position off to the central axis of the diaphragm. Furthermore, an air damping means for compensating the lowering of the air damping effect due to the dislocation of the sound ejecting hole from the central axis of the diaphragm is provided on the inner wall of the resonant chamber so as to surround the central axis of the diaphragm.

    摘要： A push-pull transducer system is provided for the reproduction of high fidelity sound to be used with amplifiers or receivers of high quality. The system consists of connecting two loudspeakers of the same size in face-to-face relationship so that where they are joined or bolted to face each other, there is provided an airtight connection.These loudspeakers can be joined directly together using a sealant for the airtight connection, or they can be attached to a mounting board, using sealing rings, if necessary. The loudspeakers are connected in series to produce push-pull air currents for the production of sound.
