The present disclosure provides a dome type diaphragm, a balanced dome diaphragm, and a speaker capable of outputting sounds in a high sound area at a high sound pressure. A dome type diaphragm according to the present disclosure includes: a first part having a first curvature; and a second part that is arranged in an inner peripheral side of the first part and is integrally provided with the first part, the second part having a second curvature that is different from the first curvature.

Dome type diaphragm, balanced dome diaphragm, and speaker

A speaker includes a flange portion, a locking member and a connecting portion. The flange portion includes a penetration hole. The locking member is arranged in the penetration hole and includes a locking portion that protrudes from the flange portion and is to be locked in a mounting hole in a prescribed size. The connecting portion connects an end surface facing the penetration hole with the locking member and is to be cut by a hand tool.

Speaker and speaker mounting structure

In a speaker damper, art sections are disposed on warp reference lines and warp reference lines. Straight sections are disposed so as to intersect intermediate reference lines at right angles. By adopting this configuration, wave parts can be adjusted so that they are less likely to expand/contract on the warp reference lines and the warp reference lines in comparison with related-art concentric circular wave parts. Further, the wave parts can be adjusted so that they are more likely to expand/contract on the intermediate reference lines. In this way, the speaker damper can perform uniform vibrating motions throughout the entire speaker damper with a simple configuration.
