Definitions

  • the cone In a cone-type speaker, the cone, and thus the voice coil, is supported at an accurate position with respect to the magnetic gap in order to reproduce sound over a wide range and frequency band, while the input signal to the voice coil is Correspondingly, it is required to vibrate the cone smoothly and with a sufficient width.
  • the support characteristics of the cone to the speaker frame especially the performance of the damper that supports the periphery of the small diameter side of the cone, are extremely important.
  • the width of the strip shape of the damper body matches the inner diameter of the cone small diameter side On the other hand, if it is less than 1 time, a sufficient vibration width cannot be secured, and if it exceeds 0.3 time, the damper body will bend downward due to the weight of the cone, making it difficult to accurately support the cone. If the length of the strip shape is less than 0.8 times the inner diameter of the cone small diameter side, a sufficient vibration width cannot be secured, and if it exceeds 2.4 times, it will be difficult to support the cone accurately. Because.
  • the dimension of the groove at the center of the damper body is a dimension range experimentally confirmed for reproducing high sound quality within the above-mentioned dimension range of the damper body.
  • positions at equal angular intervals on the circumference of the outer periphery ⁇ of the large-diameter portion of the cone are supported on the speaker frame by a plurality of elastically deformable plate-like intermediate sabots.
  • a notch groove is formed extending in the direction of the cone, and extends in the radial direction of the cone through the center of the cone support portion. Includes a second vibrating section and a radius through the center of the cone support Three damper bodies that are symmetrical with respect to a straight line extending in the direction, the left and right parts of which can be elastically deformed mutually in the direction of the cone vibration.
  • a frame-type damper for a cone-type speaker which is integrally formed on the outermost portion and extends radially through the center of the cone support portion and is provided on a speaker frame, is provided. Can be provided.

Abstract

Un amortisseur en plaques (40) pour haut-parleur comprend des sections amortisseurs, à travers lesquelles la périphérie de petit diamètre du cône d'un haut-parleur conique est soutenu par un cadre de haut-parleur (10). Ces sections amortisseurs sont disposées à intervalles réguliers sur la périphérie de petit diamètre du haut-parleur et elles sont adaptées sur le cadre (10) en des points situés sur des lignes (a) s'étendant dans des directions radiales et traversant le centre de la partie de support du cône du haut-parleur. Chacune de ces sections amortisseurs possède une paire de sections vibrantes (42A et 42B) qui subissent une déflexion leur donnant des formes incurvées presque circulaires dans des directions opposées des deux côtés de chacune des lignes (a) et chacune de ces sections amortisseurs peut subir une déformation qui lui donne la même forme et possède une forme symétrique par rapport à chacune des lignes (a). La section vibrante gauche (42A) et la section vibrante (42B) sont déformées élastiquement de façon à présenter la même forme en raison de la vibration du cône du haut-parleur.
