摘要： A planar acoustic transducer wherein flat square-shaped permanent magnets (m18, m28, m38) are arranged on a yoke (20) with their pole faces upside so that the pole faces having different polarities may be positioned alternately. A vibrating film (26) is arranged in parallel with the pole faces of the magnets (m18, m28, m38) on the upper surface side of the yoke (20), and spirally wound paired coils (L18, L28, L38) are arranged correspondingly to the magnets (m18, m28, m38) on the front and rear surfaces of the film (26). Each of paired coils (L18, L28, L38) is spirally wound so that the paired coil may have a similar figure to that of the outer edge of the pole face of the corresponding magnet (m18, m28, m38), and the inner periphery of the coil may be positioned on the outside of the pole face from the position corresponding to the outer edge of the pole face, and then, the outer peripheries of the coils may not overlap each other. Therefore, the paired coils (L18, L28, L38) are interlinked with magnetic fluxes in the direction along the vibrating film (26).

摘要： A loudspeaker includes a diaphragm, an edge, and a voice coil. The diaphragm includes a groove having a concave cross section. Also, the diaphragm is in a horizontally or vertically elongated shape. The edge is coupled to an outer circumference of the diaphragm, and has a roughly half-round shaped cross section. The voice coil is bonded to the groove. The voice coil is thicker than a depth of the groove. Also, the voice coil has a cross section in which a dimension in a direction along a plane of the diaphragm is longer than a dimension in a direction perpendicular to the plane of the diaphragm.

摘要： According to the present invention, the horizontal sections of the components of the condenser microphone are formed in an elliptical or a running track shape while the area of a diaphragm responding to sound pressure is maintained to be equal to or larger than a certain size, thus preventing a reduction in sensitivity to sound pressure as well as occupying the minimum internal space of each of various electronic products that trend toward miniaturization and thinness. Furthermore, a circular raised portion is formed at the center of the horizontal part of the casing, or a groove having an arcuate, triangular or rectangular section is formed on the horizontal part of the casing, so that the flatness of the casing and the gap between a diaphragm and a backplate are uniformly maintained, thus preventing the variations in the characteristics of the condenser microphone.

摘要： The present invention is directed to a sound reproduction device which includes an LCD (20), which is an exemplary front panel, a case (22), and an electromechanical acoustic transducer (23). TheLCD (20) isoperabletoperformapredeterminedoperation in response to an electrical signal applied thereto. A space (24) for sound emission is formed between the case (22) and the LCD (20). The electromechanical acoustic transducer (23) is connected to the case (22), and emits sound to the space (24). If the electromechanical acoustic transducer (23) emits the sound to the space (24), energy of the emitted sound causes the LCD (20) to vibrate and thereby to externally output the sound.

摘要： A loudspeaker comprising an enclosure 31 provided with a second diaphragm disposed at an opening, and at least one sound generator 40 coupled acoustically with the enclosure. The sound generator is provided with a first diaphragm 27, wherein the second diaphragm has an area greater than an area of the first diaphragm. In the present invention, shape of the enclosure, positioning and shape of the first and the second diaphragms can be designed at a designer's option. Thus a small-sized electronic apparatus can be obtained with a greater designing freedom, while a large-sized diaphragm prevents a decrease of generated sound pressure.

摘要： The modifications to the computer consist of placing piezoelectric patches behind the LCD and directly to the back wall of the laptop lid. Damping materials and stiffeners are also added to the back wall to reduce structural resonance. A system consisting of an audio amplifier (5) and transformer (6) is used to drive the piezo speaker (7).

摘要： A flat panel rectangular or elliptical loudspeaker has one or more anisotropic diaphragms (14, 15), made of double skinned fluted polypropylene copolymer (core flute) or corrugated cardboard, having a longitudinal bending strength greater than the transverse bending strength. The diaphragm is vibrated by a driver unit (16) which comprises a magnet (17) and voice coil (18). In this version the magnet (17) is mounted on the rear diaphragm (15) and the voice coil (18) is mounted on the front diaphragm (14). The two diaphragms (14, 15) are mounted at their edges to a frame (11) with the driver unit (16) mounted in the space enclosed by the frame and the diaphragms.

摘要： A planar diaphragm loudspeaker (10) incorporating a planar diaphragm (12) having multiple sound producing regions (36, 38, 40), a support frame (16), and one or more electromagnetic drivers (18) coupled to the sound producing regions on the rear surface (26) of the diaphragm. A first sound producing region (40) is formed generally centrally on the rear surface (26) of the diaphragm (12), and second (36) and third (38) sound producing regions are formed on opposite sides thereof. The sound producing regions comprise raised portions on the rear surface of the diaphragm which are symmetrical about both first and second orthogonal axes (x, y) for balance. Cross members (22) extend between opposite sides of the support frame (16) so as to overlay all of the sound producing regions to selectively mount separate electromagnetic drivers for coupling to each sound producing region, as well as to mount one or more anchors (70) extending from the cross members to the perimeters of the second and third sound producing regions in order to isolate them from the first sound producing region. The support frame is constructed from hollow rectangular channel frame members (74) which are joined together by L-shaped corner connectors (76).
