Title: Loudspeaker grill
Inventor: NANBA OSAMU
IPC: H04R1/02
Filed: 1997-11-21
Abstract: PROBLEM TO BE SOLVED: To eliminate the need for a large-scale processing machine by combining plural resin components and stretching a cloth over the surface of the combined components, so as to reduce the cost of metallic dies and to decrease the metallic die processing term. SOLUTION: A loudspeaker 2 is built in a display device 1 and a speaker grill 3 is fitted to the front side. The speaker grill 3 is formed by combining resin components 4, 5, fixing them by machine screw 6 and covering the surface of them with a cloth 7. In this case, since the size of the display device 1 is large, the size of the speaker grill 3 is increased also. Since the two resin components 4, 5 are combined, the cost of the metallic die for the speaker grill 3 will not increase. Because the surface of the components is covered by the cloth 7, the external appearance is not a problem even if the two resin components 4, 5 combined and they are fixed by the machine screw 6, and conversely, a sense of a high class product is provided to the product.  Since the speaker grill 3 is configured with the two resin components 4, 5, it is sufficient that a metallic die be small and the cost of the metallic die be reduced.
