  • Patent number: 10462578
    Abstract: A piezoelectric contact microphone with a mechanical vibration conduction interface provides an improved mobile electronic device microphone. In an embodiment, the mechanical vibration conduction interface is placed on a bone structure and conducts vibration from the bone structure to the piezoelectric contact microphone. Because of the direct contact, this use of piezoelectric contact microphone reduces or eliminates interferences effects due to wind and other airflow over the microphone. The mechanical vibration conduction interface materials and structure are selected to provide effective transmission of vibration from the bone structure to the piezoelectric element within the piezoelectric contact microphone. This piezoelectric contact microphone enables mobile electronic devices to provide improved voice communication, voice transcription, and voice command recognition in the presence of wind noise and other noise.

    Abstract: A rotary pump in a housing which defines an annular chamber with an inlet and outlet port which are located on either side of a partition which extends across the chamber. A flexible annular diaphragm forms one side of the chamber and faces a wall on the housing which forms the second side of the chamber. The diaphragm is sealed at its innermost and outermost edges to the housing and has legs extending away azimuthally around and integral with the diaphragm. A swashplate is connected to the legs of the diaphragm such that in use, movement of the swashplate causes the diaphragm to press precessively against the wall of the housing to force fluid drawn in at the inlet on one side of the partition around the chamber and to expel the fluid at the outlet at the other side of the partition.

  • Patent number: 9271082
    Abstract: A ring-shaped surround for a loudspeaker is disclosed, in the form of a membrane formed in a shape that, when relaxed (i.e. when not being driven), has a cross sectional shape with a first portion extending in a radial direction for a first distance, a second portion extending in an axial direction for a second distance, and a third portion extending in a radial direction for a third distance, the first and second portions being connected by a first flexible join, and the second and third portions being connected by a second flexible join, the first join having a first radius of curvature that is shorter than at least one of said first and second distances, the second join having a second radius of curvature that is shorter than at least one of said second and third distances. Thus, the surround has a Z-shape, with a first radially extending portion, and a relatively sharp bend leading to an axially-extending portion.

  • Patent number: 8867778
    Abstract: A loudspeaker has a short support post joined to the forward plate; upper end of the support post in association with the fixing post is joined to the middle part of the drum paper with the fixing post; the voice coil has the upper end thereof joined to the drum paper; when the voice coil drives the drum paper to vibrate and emit sound, the upper end of the short support post sways and generates a small offset because of the lower end of the support post being retained by the forward plate such that the voice coil moves axially in the magnetic clearance without deviation, and the voice coil is incapable of touching the yoke or the forward plate to produce noise; therefore, quality of sound output from the loudspeaker is enhanced effectively.

  • Patent number: 8813906
    Abstract: A damper speaker includes a fiber cloth woven by fibers, each of the fibers is formed by a single fiber strand or several fiber strands. The fiber strand includes a first fiber, which is one or a combination of cotton, polyester and aramid fiber. When the first fiber is the combination of cotton, polyester and aramid fiber, the weight ratio of any one to the fiber cloth is 0˜100%, and the weight ratio of the other two is adjusted. When the weight ratio of the first fiber to the fiber cloth is less than 100%, the fiber cloth includes a second fiber, which is one or a combination of rayon, silk, flax, acrylic, rubber and synthetic fiber. The speaker damper includes a layer of resin, which is absorbed by and combined with the fiber cloth. The fiber cloth is then cut into a predetermined shape through a molding means.
