There is provided a loudspeaker including a frame, a diaphragm suspended from the frame and a drive unit; wherein the drive unit has a stationary part secured to the frame and a translatable part secured to the diaphragm, the translatable part of the drive unit includes a magnet unit configured to produce a magnetic field in an air gap, the stationary part of the drive unit includes a voice coil configured to sit in the air gap when the diaphragm is at rest; and the loudspeaker is operable to energise the voice coil to cause the magnet unit to move along a movement axis relative to the voice coil, thereby moving the diaphragm along the movement axis to produce sound.

The present disclosure provides a sounding device having a first frame; a first vibration system including a first diaphragm and a first voice coil; and a magnetic circuit system with a first magnetic gap and a second magnetic gap. The sounding device further includes a second vibration system having a second diaphragm and a second voice coil, and a conductive insertion member. The total bending length of both ends of the voice coil wire can be controlled by adjusting the winding process of the second voice coil, so that the purpose of adjusting the amplitude of the second vibration system is achieved for facilitating the adjustment of the amplitude of the second vibration system.

A speaker is disclosed. The speaker includes a shell, a sounding unit and a fixing member. The shell has a sound outlet. The sounding unit includes a vibration member having a rubber diaphragm and a dome. The rubber diaphragm includes an inner suspension, an outer suspension and a main body connecting the two suspensions and covering the dome. The fixing member connects an inner fixing part of the inner suspension and the shell. The dome includes a first side close to the sound outlet and a second side far away from the sound outlet. The main body of the rubber diaphragm at the second side of the dome has a notched part formed by removing rubber of the rubber diaphragm for balancing amplitudes of the first side and the second side. The speaker can reduce the difference in amplitude and improve the acoustic stability without affecting the low frequency.

The present invention provides a speaker including a housing and a moving iron assembly. The moving iron assembly includes a first magnetic structure and a second magnetic structure, a magnetic induction diaphragm that has a suspension, a first moving iron unit and a second moving iron unit located inside the suspension, and a first coil and a second coil. The side where the first coil and the second coil are away from each other respectively correspond to the first magnetic structure and the second magnetic structure. Compared with the prior art, the magnetic flux control of the moving iron assembly circuit of the speaker is strong, and the driving force is improved.

A vibrator includes a yoke, a coil bobbin, a coil wound around the coil bobbin, a magnet, a damper, a frame, and a case housing the yoke, the coil bobbin, the coil, the magnet, the damper, and the frame. An outer edge portion of the damper is fixed to the case. The bottom face of an inner edge portion of the damper makes contact with the top end of the circumferential wall portion of the yoke. The frame is swaged to be fixed to the damper and the yoke so as to make contact with the top face of the inner edge portion of the damper and the inner surface of the circumferential wall portion of the yoke.

A speaker unit with a speaker frame and two opposing membranes each being arranged to move up and down along a main speaker axis. Two drive units are present for each membrane, having a driver static part and a driver moving part. A sealing edge suspension is connected to a perimeter of the associated membrane and to the major front surface and major back surface of the speaker unit, respectively. For each driver moving part, a spider arm suspension is present for suspending the driver moving part to the speaker frame in a flexible manner. The sealing edge suspension is at least partially positioned above the associated drive units when viewed in a direction parallel to the main speaker axis.

The present invention provides a speaker includes a frame, a vibration system, and a magnetic circuit system. The vibration system includes a diaphragm, a voice coil assembly, and a printed circuit board. The printed circuit board is arranged on both sides of the speaker. The magnetic circuit system includes a magnetic bowl and a magnet assembly. The printed circuit board includes a first fixing portion mounted with the frame, a second fixing portion mounted with the voice coil assembly, and a connecting portion. The connecting portion extends toward a direction of the magnet assembly until a part of a projection of the connecting portion along a vibration direction of the diaphragm is located on the magnet assembly. The speaker can increase the length of the force arm under the premise of minimizing the loss of BL, and improve the acoustic performance of the product.

An electrodynamic sound transducer having a transducer basket, a flexible membrane and a magnetic system having an air gap, a voice coil on a cylindrical coil carrier and a dampening central element, which is connected to the membrane, includes a coil carrier of the voice coil is connected to the membrane by a mounting adapter. The membrane is configured as a three-dimensional free-form surface except for conical shapes.

A vibration system includes: a vibration component; and an exciter attached to the vibration component. The exciter includes a fixing portion that fixes the exciter to the vibration component. The vibration component includes an affixing portion to which the fixing portion is attached, and which is more readily elastically deformable than other parts of the vibration component.

Disclosed is a loudspeaker structure including a housing, a magnetic element, a conductive ring and a first vibration assembly. The housing has an accommodation groove and a first sound cavity, the accommodation groove communicates with the first sound cavity, and the first sound cavity has a first opening. The magnetic element is disposed in the accommodation groove.
