Abstract: One or more embodiments of the present disclosure relate to a loudspeaker, comprising a driving component configured to generate a vibration based on an electrical signal; and a vibration component configured to receive the vibration of the driving component to vibrate. The vibration component includes an elastic element and a reinforcing member. The elastic element includes a central region, a folded ring region disposed at a periphery of the central region, and a fixed region disposed at a periphery of the folded ring region. The elastic element is configured to vibrate in a direction perpendicular to the central region. The reinforcing member is connected with the central region. The reinforcing member includes a reinforcing part and a plurality of hollow parts. Vibrations of the reinforcing member and the elastic element generate at least two resonance peaks within an audible range of human ears.

Abstract: A full-frequency band high quality speaker with a bar and sound tunnels includes a voice coil, magnet, diaphragm and magnetically conductive structure; the diaphragm is conical, a bridge-style bar is on the surface of at least one side of the diaphragm; the diaphragm includes at least two grooves, each horizontally radial; each groove crosses the bridge-type bar in the horizontal direction and the length direction of the groove is perpendicular to the bridge-type bar; the groove is concave on the surface of the diaphragm to form a sound tunnel. The diaphragm is changed to the current standard vibration mode, and the timbre of treble register is not bright and the timbre of bass register is not sonorous and mellow enough from the perspective of vibration, resonance and phonation. The practice proves that the improved scheme has outstanding substantive characteristics and remarkable technical progress, and has obtained obvious technical results.

Abstract: The present invention provides a silicon speaker comprising an MEMS acoustoelectric chip and a PCB substrate, wherein the MEMS acoustoelectric chip comprises a corrugated diaphragm on a silicon substrate; and one side surface of the MEMS acoustoelectric chip is metalized, and the metalized side surface of the MEMS acoustoelectric chip is connected with the PCB substrate. The corrugated diaphragm is electrically conductive and interconnected with metal paths on MEMS acoustoelectric chip, which is led out to a first PCB metal path as one electrode. A second PCB metal path below the MEMS chip forms another electrode of the electrostatic actuator. The silicon speaker provided by the present invention lowers manufacturing costs of the speaker, and allows the diaphragm to generate high and repeatable/reliable sound pressure upon large displacements so as to improve the sounding effects of the speaker.

Abstract: The invention discloses a manufacturing method of a speaker vibrating diaphragm by controlling a ratio of fiber materials, the method comprising the steps of: (A) fabric provision: providing a fabric interwoven by a plurality of warps and a plurality of wefts; (B) impregnation: impregnating the fabric in a resin solution; (C) drying: drying the fabric impregnated with resin solution; (D) formation: pressing the dried resin-impregnating fabric to form a predetermined shape; and (E) cutting: cutting the formed speaker vibrating diaphragm from the fabric. Each of the plurality of warps and each of the plurality of wefts of the fabric has an individual yarn count and material composition. By controlling a combination of the yarn counts of the plurality of warps and the plurality of wefts, a total number of threads and a material composition ratio of the warps and wefts required for the vibrating diaphragm are achieved.

Abstract: For a MEMS component, in the layer structure of which at least one sound-pressure-sensitive diaphragm element is formed, which spans an opening or cavity in the layer structure and the deflections of which are detected with the aid of at least one piezosensitive circuit element in the attachment area of the diaphragm element, design measures are provided, by which the stress distribution over the diaphragm surface may be influenced intentionally in the event of deflection of the diaphragm element. In particular, measures are provided, by which the mechanical stresses are intentionally introduced into predefined areas of the diaphragm element, to thus amplify the measuring signal. For this purpose, the diaphragm element includes at least one designated bending area, which is defined by the structuring of the diaphragm element and is more strongly deformed in the event of sound action than the adjoining diaphragm sections.

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.
