摘要： PROBLEM TO BE SOLVED: To perform good acoustic reproduction by constituting a diaphragm to which a coil bobbin provided with a voice coil is attached by connecting at least two layers which are surface and rear layers having different internal losses from each other with the layers. SOLUTION: A magnetic circuit, which has a magnetic gap part 14 and a coil bobbin 6 which is provided with a voice coil 7, are attached to this unit, and the unit is provided with a diaphragm 5 which is supported with the coil 7, movable and placed inside the part 14. The diaphragm 5 consists of at least two layers that are surface and rear layers 5a and 5b which have different internal losses from each other and are connected together. The layer 5a is formed from a material which is hard, whose sound wave velocity is fast and whose internal loss is large. The layer 5b is formed from a material which is soft and strong, whose sound wave velocity is slow and whose internal loss is large. Because the layers 5a and 5b are stuck together when sheets are made, they are connected with each other, without being glued with adhesive, etc.

摘要： PURPOSE:To prevent the inconvenience due to vibration from generating even if an electronic equipment is arranged on supports by placing the electronic equipment on the supports inserted into the plural support insertion parts provided on a speaker box. CONSTITUTION:Four cylindrical support insertion holes 4 are provided at the prescribed location of the flat part 2a of a speaker box 2 and the diameters of these support insertion holes 4 are made slightly larger than the diameter of a cylindrical support 7. A placing plate 6 of a prescribed size where the support 7 is fixed at the location corresponding to each of the four support insertion holes 4 of the flat part 2a of the speaker box 2 is provided. Each of the four supports 7 of this placing plate 6 is inserted into the support insertion holes 4 of the flat part 2a of the speaker box 2. Further, this speaker box 2 is placed at a prescribed location, a display 1 is placed on this placing plate 6 and the display is used. Therefore, the vibration due to the sound pressure of the speaker box 2 is attenuated by the opening of the inner walls of the support insertion holes 4 and the outer periphery of the support 7.

摘要： PURPOSE:To obtain desired efficiency by combining first and second cylinders in which bass reflex type ducts are formed on a front side and a back side of a cabinet. CONSTITUTION:An aperture 13A which forms the duct 13 for bass reflex and a first cylinder 13B are formed in the inside of the front side cabinet 11 or the back side cabinet 12 of a bass reflex type speaker device 10 by integral molding. A second cylinder 13C whose cross-sectional shape is larger than that of the first cylinder 13B by a prescribed size is formed by the integral molding at a position covering the first cylinder 13B when the duct is assembled in the inside of back side cabinet 12 or the front side cabinet 11, and the front side cabinet 11 and the back side cabinet 12 are assembled, then, the duct 13 provided with a folding part with the same length as that of the first cylinder 13B and the second cylinder 13C can be formed. Therefore, it is possible to extend route length by folding the duct 13 with simple constitution, and to obtain the desired efficiency.

摘要： PURPOSE:To prevent deterioration in reproduced sound due to resonance and anti-resonance of ports by providing plural acoustic tubes (ports) whose equivalent mass is equal and whose difference differs from each other. CONSTITUTION:Two ports 12, 13 are provided onto a front face 10f of a cabinet 10 at a proper interval, lengths L12, L13 of both the ports 12, 13 are made different and each equivalent mass is made equal. Thus, the resonance of the port 12 and the anti-resonance of the port 13 are cancelled to avoid a large peak. Thus, the electroacoustic transducer is obtained, in which the deterioration in the sound quality of the reproduced sound due to the resonance and the anti-resonance of the ports is prevented.
