发明名称 Electro-Acoustic Converter, Module Using Same, Electronic Device, and Apparatus
摘要 Disclosed is a speaker comprising a frame connected with a magnetic circuit having a magnetic gap, a voice coil disposed adjacent to but not in contact with an upper side of the magnetic circuit, and a diaphragm bonded to a circumferential edge of the frame, wherein the frame and the diaphragm are configured into such peripheral shapes that conform to a mounting space allowed for the speaker inside an apparatus. This structure allows an external shape of the speaker to be freely configurable according to a limited space, yet the irregularly-shaped diaphragm is capable of being driven with an uniform amplitude, thereby providing an advantage of down-sizing and high performance.
