Title: Speaker
Inventor: MORI TOORU
IPC: H04R1/30
Filed: 1982-04-23
Abstract: PURPOSE:To make the frequency characteristics flat and to improve the directivity, by cancelling the peak on the sound pressure versus frequency characteristics due to the resonance of a diaphragm so as to make the peak coincident with the dip of the diffractive effect of an equalizer. CONSTITUTION:The shape of plane placing oppositely to the diaphragm of the equalizer 5 provided at the front surface of a speaker diaphragm 4 is taken as a shape in which the length of lateral and longitudinal axes is not coincident. That is, the path length of diffraction of sound waves is changed more or less with excellent design performance as it is, and the shape of the equalizer placed in front of the sound irradiating plane of the speaker is taken as shown in Fig. (front view). That is, when the equalizer is increased in the size, a dip frequency is lower and when smaller, the dip frequency is higher, the shape has a multiplicable effect. A frame 8 is screwed to a magnetic circuit 7, the diaphragm 4 is bonded to the frame 8 via an edge 9, the upper part of a voice coil 10 is bonded to the diaphragm 4 and arranged in a magnetic gap. The equalizer 5(diffuser) is fitted to the frame 8 with plural number of spokes to hold the gap position 8 with the diaphragm 4.

Title: Link connecting mechanism
Inventor: NISHIKAWA MASUMI
IPC: F16C11/04
Filed: 1985-03-30
Abstract: PURPOSE:To enable a smooth movement to be attained, by always pressing an engaged hole, formed in a tapered surface, to the tapered surface of a pin and removing the looseness between the engaged hole and the pin. CONSTITUTION:An O ring 5, forcing a link 4 to be pressed in the direction of a different ink 3, provides the engagement between an engaged hole 4a and a pin 7 so as to be placed always in a condition with no looseness. External force, applied in the direction of tension or compression to the link 4 serving as the second member, causes force, corresponding to a tapered component, to act tending to move the link 4 in the direction of an arrow head in the drawing, but the force is absorbed by the O ring 5. Accordingly, even if wearing is generated in a tapered surface 7a of the pin and a tapered surface of the engaged hole 4a, a mechanism, continually compensating the engagement between the tapered surfaces so as to remove a play, attains a smooth movement.
