A speaker and a method of manufacturing the speaker are provided. The speaker includes a terminal board attached to a side surface of the frame and connected to the electric signals, a dust cap for preventing the inflow of foreign matters into a gap of the magnetic circuitry, an edge formed on the circumference of the cone paper, and a gasket acting to prevent the resonance of the frame and a cover with metal parts, in fixing the frame and the cover of the speaker, and to prevent the delamination and separation of the edge from the cone paper by the vibration of the cone paper. The damper is maximally enlarged in its size, thereby maximizing amplitude of output sound via the damper and attenuating a low band factor. The damper is connected to the upper surface of the voice coil and the upper surface of the frame. Thereby, in case of a speaker with a size of less than PHI45 mm, the minimum resonance frequency can be attenuated to less than 300 Hz. The speaker of the present invention may be applied to various electric appliances and satisfy the trend of compactness and slimness. |
