    • PROBLEM TO BE SOLVED: To provide an underwater speaker that can be used in water and under various adverse environments by overcoming the problem that in order to use a speaker in water, it is necessary to cover a cone paper as a diaphragm and an important unit with a strong material having high waterproofness in order to protect them from water and water pressure; however, vibration of the diaphragm, which is an important function as a sound source, is reduced as they are protected stronger, thus failing to obtain a sufficient sound pressure.SOLUTION: A vibration speaker is employed to ensure a sufficient sound pressure as a speaker, even with a diaphragm, which is important as a sound source, disposed inside a body. A housing case as a speaker body and an object for attaching the housing case are completely adhered to each other and are integrated together. Thereby, the vibration speaker has a structure that protects a speaker unit from bad conditions such as water, dust, water pressure and strong wind.
    • 要解决的问题:为了提供可以在水中和各种不利环境下使用的水下扬声器,通过克服为了在水中使用扬声器而需要覆盖锥形纸作为隔膜的问题,并且 一个重要的单位,具有很强的防水性能,以保护他们免受水和水的压力; 然而,作为声源的重要功能的隔膜的振动被减小,因为它们受到更强的保护,因此不能获得足够的声压。 解决方案:使用振动扬声器来确保作为扬声器的足够的声压,即使是作为声源重要的隔膜设置在体内。 作为扬声器主体的壳体和用于安装壳体的物体彼此完全粘合并且集成在一起。 因此,振动扬声器具有保护扬声器单元免受诸如水,灰尘,水压和强风等恶劣条件的结构。 版权所有(C)2013,JPO&INPIT
