Abstract

PURPOSE:To increase comparatively both the specific gravity and rigidity of a cassette housing and to obtain better sound quality, by using the resin mixed with a ceramic material or unifying a ceramic member and the resin to form the cassette housing. CONSTITUTION:A resin part 11 consists of the composite resin mixed with a ceramic material, and a cassette housing 1 is unified with a ceramic plate 10. Thus both the specific gravity and rigidity of the housing 1 can be set at a comparatively high level respectively in order to obtain better sound quality. While the housing 1 is formed with the plate 10 having a comparatively large outer size to form a flat plate part and the part 11 which can reduce its contact area to the plate 10 by means of a rib 11d. As a result, the warp of the housing 1 due to the contraction of the part 11 can be extremely reduced. Furthermore it is possible to prevent the destruction of the plate 10 owing to the contraction of the part 11.

According to such a cheats cassette, the specific gravity and rigidity of the cassette case (1) are relatively high compared to those constructed only of resin, and better sound quality can be obtained. Also, cassette case (1)
Ceramic grate 4 with relatively large external dimensions forming a flat plate portion thereof, and this ceramic plate 01)
The cassette cassette case (1) has a relatively small contact area (1 m) with a relatively small contact area, and the warping of the cassette casing (1) due to shrinkage of the resin part (If) during molding can be extremely minimized. )01 can be prevented from being destroyed. Furthermore, a protrusion (
10a), and this protrusion (10a) is connected to the resin part (11
) so that the ceramic plate α [1] and the resin part (11) can be mechanically connected, and the ceramic plate α [11 can be prevented from coming off from the resin part (11). Since the window plate (9) is held between the 0I and the resin part (11), the resin part aυ
Even if it is made of an opaque composite resin, the inside of the cassette case (1) can be visually viewed through the window plate (9) without causing the same inconvenience.
