Abstract: A diaphragm and suspension edge includes inner and suspension edge portions. The inner suspension edge portion includes an inner suspension edge body, and one or more inner side elastic ribs protruding relative to the inner suspension edge body. Each inner side elastic rib forms a bulge on a first side of the inner suspension edge portion, and forms a flute on the opposite side. The outer suspension edge portion includes an outer suspension edge body, and one or more outer side elastic ribs protruding relative to the outer suspension edge body. Each outer side elastic rib forms a protrusion on a first side of the outer suspension edge portion, and forms a groove on the opposite side. The suspension edge restricts the displacement direction of the vibration unit of a speaker in the axial vibration direction thereof to prevent offset of the vibration unit.

Abstract: Small-scale audio speakers of various shapes are installed in parent devices. Inner casings, and the surrounding vibration-damping zone often required between such casings and the surrounding parent-device walls, are omitted from the assembly. During integration with the parent device, each un-encased speaker and its signal lines are sealed into a single-walled enclosure that incorporates a parent-device wall as at least one side. The entire interior of the single-walled enclosure becomes a back volume for the speaker. The single-walled enclosure may incorporate seals at the speaker's audio-output aperture, at the pass-through for the signal lines, and at the interface between the parent-device wall(s) and the added side(s) constituting the single-walled enclosure. Optional adhesive-free sealing options include sliding tabs held by a snap-lock latch.

Abstract: A loudspeaker includes a voice coil in a balanced state. In the loudspeaker, at least a first suspension element acts on a first side of the voice coil, and at least a second suspension element acts on a second side of the voice coil. The loudspeaker includes a symmetric magnet assembly. The voice coil aligns with the symmetric magnet assembly. The symmetric alignment contributes to the loudspeaker yielding substantially symmetric motor force (BL), suspension stiffness (K), and inductance (Le).

Abstract: The present invention provides a speaker structure, comprising a vibrating component, an electromagnetic component, an casing and an integral washer conductive sheet. The electromagnetic component comprises a central magnet and peripheral magnets which are disposed around the central magnet. The integral washer conductive sheet replaces a washer structure and an conductive sheet structure in a traditional speaker structure and is integrally formed by the washer and an conductive sheet which are combined into one part. The integral washer conductive sheet comprises a washer part and an conductive sheet part, wherein the washer part is disposed on the peripheral magnets and the conductive sheet part extends out of the casing. By adopting the integral washer conductive sheet according to the present invention, those skilled in the art can simplify an internal structure of the speaker, save production materials, simplify molding and assembling procedures, and improve production efficiency.

Abstract: There is provided an electrodynamic sound transducer comprising a chassis and at least one diaphragm which is capable of vibrating and which at its edge has at least two oppositely disposed fixing portions for fixing the diaphragm to the chassis. The edge of the diaphragm is not connected to the chassis between the fixing portions so that the diaphragm can vibrate freely at those locations.

Abstract: A loudspeaker includes a diaphragm body having a dome shape protruding upwardly, a magnetic circuit disposed below the diaphragm body, a voice coil coupled to the diaphragm body, an edge coupled to an outer circumference of the diaphragm body, and a frame coupled to the edge. The edge includes a first coupling portion provided at an outer circumference of the edge, a second coupling portion provided at an inner circumference of the edge and coupled to an outer circumference of the diaphragm body, and a roll portion disposed between the first coupling portion and the second coupling portion. The edge has a surface facing downward. The frame has a connecting surface disposed below the second coupling portion and coupled to the surface of the edge at the first coupling portion of the edge. This loudspeaker can decrease distortion of sound.
