  • Patent number: 8090138
    Abstract: A vehicle audio device includes a vibrator (30), a first threaded member (20), a second threaded member (32), and a ring-shaped resilient member (25). The first threaded member (20) includes a tubular portion (22), an external thread (22m) formed on an outer surface of the tubular portion (22), and a flange (24) formed on one end of the tubular portion (22). The resilient member (25) is fitted around the tubular portion (22) of the first threaded member (20) so as to axially oppose the flange (24) of the first threaded member (20). The second threaded member (32) includes a ring-shaped portion (32f) axially opposing the resilient member (25) from the side of the resilient member (25) not opposing the flange (24) of the first threaded member (20). Internal threads (32w) are formed on an inner surface of the ring-shaped portion (32f) and are engageable with the external threads (22m) of the first threaded member (20). The vibrator (30) is mounted to one of the first and second threaded members (20, 32).

  • Patent number: 7912239
    Abstract: A flat speaker comprising a vibrating plate including a spiral voice coil, a lead portion extracted from the vice coil and reinforced by the reinforcing member, and an electric supply line; an edge portion supporting the vibrating plate; and a yoke, supporting the edge portion, on which the permanent magnet arranged to face the voice coil. The flat speaker 1 of the invention includes a vibrating membrane 2 of an insulating base film 3 with a spiral or meandering voice coil 4 formed on one or both faces thereof, a permanent magnet 5 arranged on corresponding location facing the voice coil 4; and a yoke 6 on which the permanent magnet 5 is arranged. The vibrating membrane 2 is avoided from hitting the permanent magnet by providing a perforated sheet on the back face of the yoke to control acoustic resistance.

  • Patent number: 7907742
    Abstract: An exciter for directly vibrating a board treated for dustproofing and heat dissipation, provided with a vibrator comprised of an outer yoke, a permanent magnet, and inner yoke, having a coil fixed inserted between the outer yoke and inner yoke, and having a coupler member for coupling the exciter to the surface of the board. The coupler member and vibrator are connected by an elastic member. A closed space is formed in the exciter by providing a sealing member between the outer yoke and coupler member. A through hole is formed in the outer yoke. Due to the vibration of the vibrator at the time of coil excitation, air convection is caused through the through hole between the closed space and the outside space.

  • Publication number: 20090093579
    Abstract: The oxide fine particle-containing polysiloxane composition of the present invention is obtained by mixing (A) silicon oxide fine particles and/or metal oxide fine particles with (B) polyfunctional polysiloxane in an organic solvent in the presence of a basic compound, an acidic compound or a metal chelate compound and thereby dispersing the oxide fine particles (A) in the organic solvent. In the oxide fine particle-containing polysiloxane composition, the oxide fine particles are highly dispersed in the organic solvent without using phosphoric acid or the like having an organic group of 6 or more carbon atoms or a compound having an oxyalkylene group. A polysiloxane-based cured product obtained from such an oxide fine particle-containing polysiloxane composition has excellent transparency and is hardly yellowed even at high temperatures.
