Diaphragm plate for speaker
专利汇可以提供Diaphragm plate for speaker专利检索，专利查询，专利分析的服务。并且PURPOSE:To constitute high rigidity and to increase the resonance frequency and to enable excellent reproduction, by forming ribs radially inside the fitting part of the voice coil bobbin. CONSTITUTION:The diaphragm plate main body 1 is unifiedly formed by using conventional materials such as synthetic resin plastic and metals, and the inside part than the fitting part of the coil bobbin 2 is formed to the dome 1a lower in the height h, and several ribs 1b are radially formed to the dome. Further, the inside end face 1b1 of each rib 1b is collected to the center of the diaphragm plate main body 1, and the outside end face 1b2 of each rib is mated to the insertion groove 1C of ring shape provided between the ribs 1b so that the bobbin 2 can be inserted and bonded. Thus, the height of the diaphragm plate is made to dome shape, not high, and the rigidity is high and the resonance frequency can be increased, enabling excellent reproduction.，下面是Diaphragm plate for speaker专利的具体信息内容。
