Abstract:
An electronic device has an exterior housing with a piezoelectric speaker disposed in an opening formed within the housing. The piezoelectric speaker includes a speaker diaphragm that is secured within the opening with a vibration isolator. The vibration isolator allows the diaphragm to vibrate independently from the housing.
Abstract:
A support frame for a thin mini speaker structure thinner than 10 mm includes a main body having a fixing hole, into which a magnet assembly is mounted to locate below a voice coil; two electrically conductive members disposed on the main body; two lead wire holders disposed on the main body between the fixing hole and the electrically conductive members and each defining a lead wire receiving groove thereon; a first damping colloid applied into the lead wire receiving grooves. Two lead wires of the voice coil are set in the first damping colloid in the lead wire receiving grooves and the electrically conductive members to respectively present an outward curved shape. A thin mini speaker lead wire assembling method is also introduced. With the above support frame and method, two ends of the voice coil windings can be directly used as lead wires to save additional tinsel leads.
Abstract:
An acoustic generator includes a vibrating body. The acoustic generator includes a frame member attached by a bonding material to an external peripheral portion of the vibrating body. The acoustic generator has an exciter provided on the vibrating body inside of the frame member. In this case, the acoustic generator further includes an extended portion of the bonding material provided to be extended on the vibrating body inside of the frame from the frame member.
Abstract:
A vibrating element including a diaphragm, a voice coil and a stiffening layer is provided. The diaphragm has a first surface and a second surface opposite to each other. The first surface includes a first conductive region and a second conductive region. The voice coil is disposed on the first surface. Two ends of the voice coil are electrically connected to the first conductive region and the second conductive region. The stiffening layer is disposed on the diaphragm. The diaphragm has a center region, which is enclosed and circled by the voice coil and includes an area of the diaphragm above the voice coil. The region outside the center region includes an inner circled zone and an outer circled zone surrounding the inner circled zone. At least one end of the voice coil is located in the inner circled zone and the stiffening layer covers the inner circled zone.
Abstract:
A vibration unit for an acoustic arrangement includes an encircling frame, a vibration member, and a weaving suspension extended between the vibration member and the encircling frame for enabling the vibration member to be reciprocatingly moved. The weaving suspension includes a plurality of reinforcing ribs radially and outwardly extended from the vibration member to the encircling frame to form a weaving-like structure, such that the vibration member is prohibited to move along a rib extending direction of each of the reinforcing ribs to ensure the vibration member to be reciprocatingly moved in a linear direction.

Abstract:
A casing for covering an outer yoke is provided; an acoustic cavity is formed by this casing; a diaphragm and the outer surface of a side wall of the outer yoke; a second elastic member is provided to join the outer circumferential edge of the casing to the outer circumferential edge of the diaphragm without any gap therebetween; this second elastic member includes pores formed by foaming and made of a material whose elastic modulus is smaller than that of a first elastic member; and pores communicating through from the back surface of the second elastic member, that is the inner side of the casing, to the front surface that is the opposite side of the back surface are eliminated.
Abstract:
A loudspeaker is disclosed, comprising a driven body and a suspension for providing a restoring force to the driven body, the suspension having a cup geometry wherein its attachment point on the fixed portion of the loudspeaker is displaced along the axis of motion relative to its attachment point on the driven body and comprising a first concentric region that is extendible to allow reciprocating axial movement of the driven body, a second concentric region which extends transversely from the first region toward one of the attachment points, and a circumferential member affixed to the suspension at a location between the first and second concentric regions, the circumferential member being relatively stiff compared to the material forming the first and second concentric regions.
