    • PURPOSE: A piezoelectric speaker is provided to improve a reproduction capacity in a low band by using a vibration plate having a large electromechanical coupling coefficient. CONSTITUTION: A receiving case(110) comprises a seating surface(111) having a step which is formed on an inner circumferential surface of a punched center area. An edge of a vibration plate(120) is mounted in the seating surface and is stored in the receiving case. A piezoelectric body(140) is laminated on the vibration plate. The piezoelectric body comprises a PZT(piezo-electric transducer) of a ceramic material. The piezoelectric body vibrates a vibration plate according to an AC signal of an AC signal feed part through an upper side silver paste(141) and a lower side silver paste(142) which are formed on an upper side and a lower side thereof. A damper(150) is bonded into a metal piece shape having predetermined size on the upper side of the upper side silver paste.
    • 目的:提供一种压电扬声器,通过使用具有大的机电耦合系数的振动板来提高低频带中的再现能力。 构成:接收壳体(110)包括具有台阶的就座表面(111),该台阶形成在冲压中心区域的内圆周表面上。 振动板(120)的边缘安装在就座表面中并存储在接收壳体中。 压电体(140)层叠在振动板上。 压电体包括陶瓷材料的PZT(压电换能器)。 压电体通过形成在其上侧和下侧的上侧银浆(141)和下侧银糊(142)根据交流信号馈送部的交流信号振动振动板。 阻尼器(150)在上侧银浆料的上侧粘合成具有预定尺寸的金属片形状。

    • PURPOSE: A broadband ultra thin receiver is provided to forms a magnetic circuit which is divided to the magnet of 3 by uniting a yoke having an inner side magnet of ellipse with a frame. CONSTITUTION: A vibration plate(140) is formed into a vibration plate body(144) and a vibration plate edge(142). A voice coil(130) is attached to the vibration plate. A magnetic circuit(120) consists of magnet(126) of 3 pieces attached to a flat type yoke(104). An edge of the vibration plate is combined in one side of a rectangular frame(110). The yoke is combined in the other side of the rectangular frame. The vibration plate comprises the vibration plate body used as the vibration plate for high pass frequency and the vibration plate edge as the vibration plate for the low frequency. The magnetic circuit comprises an outside magnet(122) of a pair of regular square stick types, a pair of outside plates(124), and an inner side magnet of ellipse, and an inner plate(128) attached to the inner side magnet of ellipse.
    • 目的:提供一种宽带超薄接收机,通过将具有椭圆形内侧磁体的磁轭与框架结合在一起形成分为磁体3的磁路。 构成:振动板(140)形成为振动板体(144)和振动板边缘(142)。 音圈(130)附接到振动板。 磁路(120)由附接到平型轭(104)的3个磁体(126)组成。 振动板的边缘在矩形框架(110)的一侧组合。 轭架组合在矩形框架的另一侧。 振动板包括用作高频振动板的振动板体和作为低频振动板的振动板边缘。 该磁路包括一对正方形棒型的外部磁体(122),一对外部板(124)和一个椭圆形的内侧磁体,以及安装在内侧磁体上的内部板(128) 椭圆。
