2. Description of the Related Art FIG. 4 shows the structure of a roll edge portion of a conventional cone speaker. The operation principle of the cone speaker will be briefly described below. First, when an electric signal is applied to a wire loop of a voice coil (not shown), a driving force is generated in the magnetic circuit. The driving force is transmitted to the voice coil bobbin, and vibrates the diaphragm 41 fixed to the tip of the voice coil bobbin, and emits a sound corresponding to the vibration via the diaphragm 41. The diaphragm 41 is
It has a conical shape that converts the vibration from the voice coil bobbin into a sound wave, and is provided on the rigid frame 42 via the roll edge 43 so that the periphery is located forward with respect to the listener with respect to the center of the diaphragm 41. Supported. Originally, the roll edge 43 is easily deformed by the force in the front-rear direction of the diaphragm 41 so as not to hinder the vibration of the diaphragm 41, and is repelled by repelling the force in the circumferential direction. To prevent eccentricity.

The above-described roll edge 43 is formed by an edge forming die, so that the height (H) with respect to the width (W) of the roll edge 43 is limited. Therefore, when it is desired to obtain a large amplitude with a large input, the width (W) of the edge necessarily increases, and at this time, the vibration area decreases, and the sensitivity of the roll edge 43 decreases. Therefore, it is conceivable to form the edge height (H) to be large,
At present, there is no mold having a relationship of edge height (H)> edge width (W), which hinders large-amplitude driving.
