Abstract

PURPOSE:To obtain a compact tweeter which does not require any cushioning material, such as a damping material, packing, and can be manufactured at high productivity. CONSTITUTION:A tweeter unit constituted of a magnetic circuit 1 composed of a yoke 2, a magnet 3, and a plate 4, a cone type diaphragm 11, a bobbin 12, and a center cap 20 is mounted in an enclosure 21 integrally formed of a rubber material in such a manner that the outer peripheral section 18 of the diaphragm 11 is held between a base 5 provided on the outer periphery of the plate 4 and a wall surface 22 at the inner edge section on the upper surface of the enclosure 21. Therefore, this compact tweeter which can be easily fitted to a fitting section can be manufactured at a low cost.

However, since the outer casing 21 is a hard mold case in the above-mentioned configuration, in order to prevent unnecessary vibration of the diaphragm 11, the outer peripheral edge portion of the diaphragm 11 is clamped and fixed. It is troublesome to provide the dump material 19 in the part. In addition, in most of the molded cases, the equalizer portion, the ring portion, and the outer peripheral case are formed as separate parts, and the bottom portion also uses a packing member 26 or another member such as a metal plate to prevent vibration transmission. Therefore, there is a problem that the cost becomes high.

In the tweeter thus constructed,
Since the inner casing wall surface 22 of the upper surface of the outer casing 21 made of a rubber material is flexible and elastic, the outer peripheral edge portion 18 of the diaphragm 11 is formed with the base 5.
Can be firmly held and fixed by utilizing its elasticity. Further, since it has elasticity, it is not necessary to apply a dump material to the outer peripheral edge portion 18 of the diaphragm 11 or dispose a packing on the bottom surface.

Further, since the outer casing material is formed of an elastic rubber material, there is no fear of being destroyed by a little external force, and therefore the peripheral wall portion can be made thin, and the tweeter can be made compact. Further, since the bottom surface is also integrally formed as a rubber case, it has elasticity, and not only does the packing material become unnecessary, but it has an advantage that it easily fits on the mounting surface. Further, the hole 25 for taking out the cord from the terminal plate (not shown) provided by cutting out a part of the base 5 can be easily formed from the peripheral wall to the bottom surface of the outer casing 21.

According to the present invention, by using a flexible and elastic rubber material for the outer casing material, the application and insertion of the dump material required for the outer peripheral portion of the diaphragm becomes unnecessary, Since the bottom surface can be integrally formed, it is not necessary to insert a cushioning material such as packing, and the productivity is improved by the labor saving of the tweeter assembly and the integration of the parts for manufacturing the outer casing. Furthermore, since the outer casing has elasticity, it not only has the effect of damping the transmission of unnecessary vibrations to the material of the mounting portion, but it also fits easily to the mounting portion, and it is possible to reduce the wall thickness, making the tweeter case compact. Can be done. In addition, it has an excellent texture, and when used for a tweeter of a vehicle-mounted core loudspeaker, etc., it has an effect of giving a sense of security in handling because the outer casing is not a hard one but a flexible rubber material.
