  • Publication number: 20240147149
    Abstract: An acoustic device including: a vibrating film which has waterproofness; a support which is located alongside the vibrating film in a direction and supports the vibrating film; a waterproof which is in contact with the support; an insulating plate which is located on an opposite side of the waterproof to a side where the support is arranged, and which has a first through hole leading to the vibrating film; and a metal plate which is located on an opposite side of the insulating plate to the waterproof, which has a second through hole communicating with or containing the first through hole, and which is fixed in a state pressing the insulating plate along the direction.

  • Patent number: 11543782
    Abstract: A timepiece is provided which ensures connection reliability and improves antenna characteristics. This timepiece includes a wristwatch case which houses a timepiece module, and an antenna which is provided on the upper surface of the wristwatch case in a discontinuous annular shape along the circumferential direction of the wristwatch case and electrically connected to the timepiece module in the wristwatch case from outside the wristwatch case. As a result, since the antenna is electrically connected to the timepiece module in the wristwatch case from outside the wristwatch case, the antenna and the timepiece module are unfailingly and favorably connected to each other. Accordingly, the connection reliability of the antenna is ensured and radio waves are favorably received. In addition, the reception performance and the antenna gain are improved, whereby the antenna characteristics are improved.

  • Publication number: 20220175262
    Abstract: A detection device of a body-worn device including a back cover provided with a protective glass that is a light transmissive transparent section, a holder attached to the back cover and positioned opposing the protective glass, a circuit board arranged between the back cover and the holder, an optical sensor provided on the undersurface of the circuit board opposing the protective glass so as to detect light, and energizing members arranged between the holder and the circuit board so as to force the circuit board and the optical sensor toward the protective glass. By being forced toward the protective glass by the energizing members, the circuit board reliably and favorably presses the optical sensor against the protective glass, whereby the optical sensor reliably and favorably comes in close contact with the protective glass in a stable state.

  • Patent number: 11237526
    Abstract: An antenna device includes a parasitic antenna which is a metal member used as a windshield fixing frame of a wristwatch type electronic device, and a feed antenna which is a conductor. The parasitic antenna has an annular shape, and is disposed close to the feed antenna, and is electromagnetically or capacitively coupled with the feed antenna, and acts as a parasitic antenna to which power is fed from the feed antenna in a non-contact manner, and thereby the feed antenna and the parasitic antenna act in cooperation with each other as a circular polarized antenna for receiving radar waves which are circularly polarized waves having a predetermined wavelength.

  • Publication number: 20170090327
    Abstract: An image forming apparatus including a binder pattern transfer section which transfers, at a first point, a binder pattern to a transfer belt moving in a predetermined direction, and a color pattern transfer section which transfers a color pattern to the transfer belt at predetermined timing, at a second point located on a lower flow side in a movement direction of the transfer belt than the first point, in which the color pattern transfer section applies electric charge to the binder pattern transferred by the binder pattern transfer section when the binder pattern passes through the second point along with a movement of the transfer belt, instead of transferring the color pattern to the transfer belt.
