A speaker core, speaker, and associated electronic device include at least one bent portion of a diaphragm folded ring suspended over a top of a diaphragm frame enclosing an enlarged vibration space.

The present invention provides an acoustic device including a frame, a vibration system and a magnetic circuit system. The vibration system includes a diaphragm, a voice coil, a voice coil holder connecting the diaphragm and the voice coil, and a support assembly connecting the frame and the voice coil holder. The voice coil holder comprises a first fixing portion extending toward a direction of the voice coil, a second fixing portion extending toward to the support assembly, and a first connecting portion connecting the first fixing portion and the second fixing portion. The first fixing portion is mounted to the voice coil, and the second fixing portion is mounted to the support assembly. The first connecting portion provides with a reinforcing rib protruding and extending from the first fixing portion.

The present application provides a sounding device. The sounding device includes a front surface with a sound outlet hole; a back surface; a sounding component and an outer casing. The outer casing is covered outside the sounding component. A cavity is formed between the outer casing and the end of the sounding component close to the back side. A sound guiding channel is arranged in the outer casing. One end of the sound guiding channel is communicated with the sound outlet hole, and the other end of the sound guiding channel is communicated with the cavity. The sounding device of the present application provides a smooth transmission channel for the sound from the back side by arranging the sound guiding channel in the outer casing, thereby strengthening the frontal sound of the sounding device and greatly improving the loudness of the sounding device.

The present application relates to a sound production unit and a speaker. The sound production unit includes: a frame, where the frame has a receiving space; a magnetic path system, where the magnetic path system is arranged in the receiving space, and a magnetic gap is formed in the magnetic path system; a vibration system, where the vibration system includes a first diaphragm and a second, a first voice coil assembly inserted into the magnetic gap to drive the first diaphragm to vibrate to produce a sound, and a second voice coil assembly inserted into the magnetic gap to drive the second diaphragm to vibrate to produce a sound; and an end cover. Vibrations of the sound production unit or the speaker and the like can be counteracted; cophase stacking can also be performed on sound waves; and the acoustics effect of the speaker is enhanced.

A loudspeaker system for a vehicle may include a vehicle partition panel that separates an interior space and an exterior space; a loudspeaker device comprising a frame, a diaphragm elastically supported at the frame, and a driving device that is configured to provide driving power for operating the diaphragm; and an air chamber disposed between the diaphragm and the vehicle partition panel. The frame delimits a chamber side opening of the air chamber facing the vehicle partition panel, where the vehicle partition panel comprises a vehicle partition panel opening. The vehicle partition panel opening has an extension which is smaller than the diameter of the diaphragm and smaller than an extension of the chamber side opening. The loudspeaker device is fixed to the vehicle partition panel such that the chamber side opening and the vehicle partition panel opening overlap in an overlapping area and the chamber side opening adjoins the vehicle partition panel opening.

A sound radiation apparatus includes a speaker, a first cover having an opening area provided to be superposed above at least a sound radiation port of the speaker and made up of multiple opening portions at a location superposed above the speaker, a second cover superposed on a front side of the first cover while surrounding the opening area of the first cover, and a saran net covering the first cover and a front side of the second cover and bonded to the second cover, wherein the second cover and the saran net are bonded together at an area on the second member excluding a portion surrounding the opening area of the first cover with a first adhesive and an area on the second cover surrounding the opening area of the first cover with a second adhesive having a higher bonding strength than that of the first adhesive.

A rear panel 15, which is an external member, includes a frame portion 110 including multiple sound radiation holes 150 including a first sound radiation hole 160-1 and a second sound radiation hole 160-2, a first sloping portion 160b disposed in the frame portion 110 with a first sloping surface 161a oriented in a first direction 161c, the sloping surface 161a being disposed within an area of the first sound radiation hole 160-1 in such a manner as to slope from a thickness direction (a Y-axis direction) of the frame portion 110, and a second sloping portion 162b disposed in the frame portion 110 with a sloping surface 162a oriented in a second direction 162c which differs from the first direction 161c, the sloping surface 162a being disposed within an area of the second sound radiation hole 160-2 in such a manner as to slope from the thickness direction (the Y-axis direction) of the frame portion 110.

A speaker box includes a housing which has a receiving space and a side wall having a sound hole, and a sound generator received in the receiving space and including a diaphragm including a dome and a periphery connected to the dome. The dome includes a near-end which is near the sounding hole and a far-end which is farther the sounding hole. A compliance of the near-end is less than a compliance of the far-end.

Various implementations include portable loudspeakers. Certain implementations include a portable loudspeaker that mitigates ingress of moisture, particulates, and other contaminates. In particular implementations, the portable loudspeaker includes a housing with an enclosure having a co-molded construction for ingress resistance.

An interior component of a vehicle comprises a carrier having a front face directed toward a passenger compartment of the vehicle and an opposite rear face; a speaker including an at least partially transparent diaphragm and a transducer coupled to the diaphragm. Movement of the transducer causes vibration of the diaphragm to generate sound by vibration of the diaphragm, the diaphragm having a front face directed towards the passenger compartment and an opposite rear face. The carrier provides a support along at least part of the periphery of the diaphragm where the diaphragm is attached to the carrier where the front face and the rear face of the diaphragm are free of the carrier across a part of the diaphragm surface so that the diaphragm is suspended in the carrier of the interior component.
