  • Publication number: 20210168525
    Abstract: A speaker comprises a housing, a transducer residing inside the housing, and at least one sound guiding hole located on the housing. The transducer generates vibrations. The vibrations produce a sound wave inside the housing and cause a leaked sound wave spreading outside the housing from a portion of the housing. The at least one sound guiding hole guides the sound wave inside the housing through the at least one sound guiding hole to an outside of the housing. The guided sound wave interferes with the leaked sound wave in a target region. The interference at a specific frequency relates to a distance between the at least one sound guiding hole and the portion of the housing.

  • Publication number: 20210168513
    Abstract: The present invention relates to a bone conduction speaker and its compound vibration device. The compound vibration device comprises a vibration conductive plate and a vibration board, the vibration conductive plate is set to be the first torus, where at least two first rods inside it converge to its center; the vibration board is set as the second torus, where at least two second rods inside it converge to its center. The vibration conductive plate is fixed with the vibration board; the first torus is fixed on a magnetic system, and the second torus comprises a fixed voice coil, which is driven by the magnetic system. The bone conduction speaker in the present invention and its compound vibration device adopt the fixed vibration conductive plate and vibration board, making the technique simpler with a lower cost; because the two adjustable parts in the compound vibration device can adjust both low frequency and high frequency area, the frequency response obtained is flatter and the sound is broader.

  • Publication number: 20210168522
    Abstract: A speaker comprises a housing, a transducer residing inside the housing, and at least one sound guiding hole located on the housing. The transducer generates vibrations. The vibrations produce a sound wave inside the housing and cause a leaked sound wave spreading outside the housing from a portion of the housing. The at least one sound guiding hole guides the sound wave inside the housing through the at least one sound guiding hole to an outside of the housing. The guided sound wave interferes with the leaked sound wave in a target region. The interference at a specific frequency relates to a distance between the at least one sound guiding hole and the portion of the housing.

  • Patent number: 11020514
    Abstract: An absorbable iron-based alloy medical device implant, comprising an iron-based alloy substrate (11) and a degradable polymer (13) provided on a surface of an iron-based alloy substrate (11), and a zinc-containing protective member (12) provided on the surface of the iron-based alloy substrate (11). The zinc-containing protective member (12) is either a zinc compound or a mixture comprising the zinc compound and at least one of a phosphate-containing compound, a degradable binder, or a water-soluble binder. The weight ratio of the zinc compound in the mixture is ?20% and <100%. The zinc-containing protective member (12) can delay corrosion of the iron-based alloy substrate (11) during an early stage of medical device implantation. The iron-based alloy substrate (11) is essentially corrosion-free during the early stage of medical device implantation, and is therefore able to satisfy clinical requirements of mechanical performance during the early stage of medical device implantation.
