Definitions

  • the invention relates to a flat panel speaker.
  • Both the existing flat-panel speaker and the conventional cone woofer are connected to the voice coil by the center of the diaphragm, and the voice coil diameter is much smaller than the diaphragm diameter.
  • This structure of driving the diaphragm from the center as the overall piston vibration is due to vibration. Influenced by factors such as film rigidity and vibration quality, the diaphragm will generate harmful split vibration and side ring vibration when the piston vibrates. It is difficult to achieve better sound quality and performance of the speaker, and also due to the speaker compliant and diaphragm.
  • the diameter of the control voice coil is difficult to design with large diameter, which greatly limits the current performance improvement of speaker efficiency and power. This problem is more prominent in thin flat panel speakers, and it is easy to produce large peaks or large valleys in frequency response. Make the frequency response curve not straight.
  • An object of the present invention is to provide a peri-membrane push type flat panel speaker which can effectively eliminate side ring vibration and split vibration, and can improve electroacoustic conversion efficiency and power, in view of the above problems existing in the conventional speaker.
  • the object of the present invention is as follows:
  • the present invention includes a voice coil, a diaphragm, a folding ring, and a magnetic circuit system.
  • the voice coil is fixedly connected to a portion of the periphery of the diaphragm and the folding ring, and is suspended from the magnetic circuit system.
  • the magnetic circuit a structure in which the diaphragm is driven by the periphery of the diaphragm to vibrate the piston is formed.
  • the technical effect of the present invention is:
  • the present invention is connected to the periphery of the diaphragm by the voice coil,
  • the structure that drives the diaphragm to vibrate the piston from the periphery effectively eliminates the influence of the side ring vibration on the sound quality caused by the existing speaker driving the diaphragm from the center; in addition, the invention increases the diameter of the voice coil and can also improve Speaker efficiency and power.
  • Embodiment 1 is a schematic structural view of Embodiment 1.
  • Embodiment 2 is a schematic structural view of Embodiment 2.
  • Fig. 3 is a schematic structural view of the third embodiment.
  • the first embodiment includes a folding ring 1, a diaphragm 2, a voice coil 3, and a magnetic circuit system 4.
  • the magnetic circuit system 4 adopts an outer magnetic type, and the voice coil 3 and the diaphragm 2 have a circular shape, and The diameter of the voice coil 3 is equal to the diameter of the diaphragm 2, and the voice coil 3 is fixedly connected to the intersection of the periphery of the diaphragm 2 and the folding ring 1 in a conventional speaker assembly process, and suspended in the magnetic circuit of the magnetic circuit system 4, A structure in which the diaphragm 2 is driven by the periphery of the diaphragm 2 to form a piston vibration is formed.
  • the magnetic circuit system 4 and other structures in this embodiment are existing mature technologies, and are not described herein.
  • the second embodiment includes a folding ring 12, a diaphragm 22, a voice coil 32, and a magnetic circuit system 42.
  • the magnetic circuit system 42 adopts an inner magnetic type, and the voice coil 32 and the diaphragm 22 have a circular shape, and The diameter of the voice coil 32 is equal to the diameter of the diaphragm 22, and the voice coil 32 is fixedly connected to the intersection of the periphery of the diaphragm 22 and the folding ring 12 in a conventional speaker assembly process, and suspended in the magnetic circuit of the magnetic circuit system 42 to form
  • the diaphragm 22 is driven by the periphery of the diaphragm 22 to perform vibration of the piston.
  • the third embodiment is a high-power woofer, including a folding ring 13, a diaphragm 23, a voice coil 33, a magnetic circuit system 43 and an elastic wave 5.
  • the magnetic circuit system 43 adopts an external magnetic type, a diaphragm.
  • the voice coil 33 is fixedly connected to the intersection of the periphery of the diaphragm 23 and the folding ring 13 in a conventional speaker assembly process, and suspended in the magnetic circuit of each system 43 to form a diaphragm 23 driven by the periphery of the diaphragm 23.
  • the shape of the voice coil and the diaphragm of the utility model are consistent, and various shapes such as an ellipse, a rectangle, a polygon or a triangle can be used in addition to the circle.
  • the size of the center voice coil of the present invention may be equal to the size of the diaphragm, as described in the above embodiments.

Abstract

La présente invention concerne un haut-parleur monté sur plaque de type à entraînement par le bord à membrane vibrante, qui comprend : une bobine acoustique (3), une membrane vibrante (2), un anneau pliant (1) et un système à circuit magnétique (4). La bobine acoustique (3) est fixée sur la partie de liaison des bords de la membrane vibrante (2) et de l'anneau pliant (1), et est suspendue dans le circuit magnétique du système à circuit magnétique (4), la structure du bord de la membrane vibrante (2) entraînant la membrane vibrante (2) de manière à faire vibrer un piston. La présente invention permet d'éliminer la déformation de la tonalité produite par la vibration de la cloison et la vibration inverse de l'anneau de bord, que l'on observe généralement dans les haut-parleurs classiques, et d'améliorer l'efficacité et la puissance du haut-parleur.
