この考案は、周辺多数駆動のドーム振動板を有
するスピーカーの改良に関する。[Detailed Description of the Invention] This invention relates to an improvement of a speaker having a dome diaphragm driven by multiple peripherals.
従来の周辺多数駆動のドーム状振動板を有する
スピーカーは、第１図のように、ドーム状振動板
１の外周縁を、複数の圧電素子２などの振動子の
中心に、点接触的に接着３していたので、外周縁
の円周部の接着部３が特定せず、製作時不便であ
るとともに、接着が均一でないため振動で外れや
すく、また、接着剤が固まつた固形物が振動板１
の振動部内に存在するため、振動板１の振動モー
ドを乱したり、偏り振動や歪みを発生する欠点が
あつた。 In a conventional speaker having a dome-shaped diaphragm with multiple peripheral drive, as shown in FIG. 3, the adhesive part 3 on the circumference of the outer periphery cannot be specified, which is inconvenient during production, and because the adhesive is not uniform, it is easy to come off due to vibration, and solid objects with hardened adhesive may be exposed to vibration. Board 1
Since it is present in the vibrating section of the diaphragm 1, it has the drawback of disturbing the vibration mode of the diaphragm 1 and generating uneven vibrations and distortions.
この考案は、複数個の圧電型振動子でドーム状
振動板の外周縁を分散駆動するドーム型スピーカ
ーに於て、第２図のような、ドーム状の外周縁部
６の外側に突出した接着部７を形成した振動板８

る。したがつて、振動板８の接着部７の数だけ圧
電素子３を接着することが可能で、駆動点を多数
外周部に設けることができるので、大入力に耐え
るとともに、大出力が得られるドーム形圧電スピ
ーカーである。 This idea is based on a dome-shaped speaker in which the outer periphery of a dome-shaped diaphragm is driven in a distributed manner by a plurality of piezoelectric vibrators. diaphragm 8 forming part 7;
This is a speaker in which the center part of the bimorph piezoelectric element 3 is adhered to the adhesive part 7 as shown in FIG. Therefore, it is possible to bond as many piezoelectric elements 3 as there are bonding parts 7 of the diaphragm 8, and a large number of driving points can be provided on the outer periphery, so that the dome can withstand large inputs and obtain large outputs. It is a shaped piezoelectric speaker.
