  • Publication number: 20240414479
    Abstract: A speaker, including a paper cone, a damping ring, a damper, a magnetic assembly, and a voice coil, is provided. The damping ring is integrally connected to the paper cone. The damping ring has a first side edge and a second side edge opposite to each other, and the first side edge is connected to the paper cone. The damper has an inner edge and an outer edge. The outer edge abuts against the second side edge of the damping ring. The magnetic assembly abuts against the inner edge of the damper. The paper cone, the damping ring, the damper, and the magnetic assembly define a space. The voice coil is disposed in the space and abuts against the paper cone.

  • Patent number: 10555084
    Abstract: A loudspeaker includes a yoke, an annular magnet, a voice coil, and an open type inductive coil. The annular magnet is combined to the yoke, and a magnetic gap is provided between the annular magnet and the yoke. The voice coil is disposed in the magnetic gap. The open type inductive coil is combined to the yoke or the annular magnet, and the open type inductive coil corresponds to the voice coil. An inductive gap is located between the open type inductive coil an the voice coil, where the open type inductive coil includes a coil unit and two signal transmission lines. The coil unit includes opposite open ends, first ends of the signal transmission lines are respectively connected to the open ends, and second ends of the signal transmission lines are exposed out of the yoke and the annular magnet, so as to transmit mutual inductance signals between the coil unit and the voice coil to outside.

  • Publication number: 20150016653
    Abstract: A tuning headphone is adapted to engage to the user's ear. The tuning headphone includes a perforated frame, a tuning frame and an acoustic generator. The perforated frame comprises a frame annular portion and a frame flat surface. The frame flat surface is arranged at a distal end of the frame annular portion away from the user's ear, and has portions defining at least one frame opening. A surface of the frame annular portion proximate to the user's ear is a curved inner face. The tuning frame has portions defining at least one opening and rotatably covers an end of the perforated frame distal from the user's ear, thereby providing adjustability to the air communicable area between the opening and the frame opening. Moreover, the acoustic generator is configured at a proximal end of the frame annular portion near the user's ear.

  • Publication number: 20140334656
    Abstract: A headphone with passive diaphragm is adapted to engage to the user's ear. The headphone with passive diaphragm includes an acoustic generator and a diaphragm assembly. The diaphragm assembly includes an annular member and a passive diaphragm. The acoustic generator is configured at a proximal end of the annular member near the user's ear. The passive diaphragm is configured to seal the annular member at a distal end thereof away from the user's ear. The passive diaphragm, annular member, and the acoustic generator cooperatively form a rear chamber.
