摘要： A vibration unit includes an encircling frame defining a vibration cavity therewithin, a vibration member disposed in the vibration cavity, and a suspension including an elastic diaphragm having a periodical wave-shape extended between the vibration member and the encircling frame to support the vibration member within the vibration cavity. The wave-shape diaphragm provides a 3-dimensional connection between the vibration member and the encircling frame to self-generate a repelling force to against a lateral movement of the vibration member so as to ensure the vibration member to be reciprocatingly moved in a linear direction.

摘要： An acoustic device includes a diaphragm, a frame, and a suspension element that couples the diaphragm to the frame such that the diaphragm is movable in a reciprocating manner relative to the frame. The suspension element includes a first surround element and a second surround element that have respective inner landings between which a region proximal to an outer edge of the diaphragm is disposed. The inner landings are mechanically coupled by an adhesive material disposed along an inner periphery of the suspension element. The adhesive material has a viscoelastic response that increases stiffness as frequency increases, resulting in a shift of a first breakup mode of the acoustic device from a first frequency to a second, higher frequency.

摘要： A coaxial loudspeaker has a first driver producing sound within a first frequency band and a second driver coaxial with the first driver producing sound within a second higher frequency band. The first driver includes a first moveable membrane coupled and moveable relative to a frame to generate sound waves within the first frequency band. The first moveable membrane extends from adjacent a central axis to an outer part above and spaced apart from a rim of the frame, the outer part being resiliently coupled to the rim. The second driver includes a second moveable membrane generating sound waves within the second frequency band. The second moveable membrane is behind or below the first moveable membrane and the resilient coupling is behind the first moveable membrane extending from the rim to the outer part so the surround is not an obstacle to second driver sound waves.

摘要： An edge has an inner circumferential portion connected to an outer circumferential portion of a diaphragm, and is made of an annular elastic deformation member. A frame is connected to an outer circumferential portion of the edge, and supports the diaphragm through the edge. A magnetic circuit displaces the diaphragm in a first direction that is a sound emission direction and in a second direction that is an opposite direction to the sound emission direction, and vibrates the diaphragm. In a region between the inner circumferential portion and outer circumferential portion of the edge, the edge includes a rib, which is protruded in the second direction, and limits a stroke of the diaphragm in the second direction.

摘要： An acoustic unit, which is arranged for coupling with a vibration system to produce an audio sound, includes a frame, a vibration member for being reciprocatingly moved in response to the vibration system; and a resilient suspension which is provided around the vibration member and is located between the vibration member and the frame, wherein the suspension has a stretching section integrally extended from the vibration member and a cushioning section integrally extended from the stretching section to the frame. The cushioning section only allows the stretching section to displace along a direction the same as a vibration direction of the vibration member to restrict a vibrating movement of the vibration member. The acoustic unit is incorporated with an acoustic module, wherein when a loudspeaker of the acoustic module operates, the acoustic unit synchronously vibrates to provide an enhanced low frequency audio effect.
