发明名称 Speaker
摘要 The invention relates to a small speaker. A speaker 1 comprises: a magnetic circuit 3 having a yoke 7, a magnet 15, and a pole piece 16; a vibration system 4 having a voice coil 18 and diaphragm 19 which are joined to each other through a voice coil bobbin 23; and a frame 2 which holds the magnetic circuit 3 and the vibration system. The voice coil is placed in a magnetic gap 17. In the speaker, dampers 26 which are extended respectively from a plurality of places of an opening side end portion of the voice coil bobbin are disposed, and tip end portions of said dampers are bonded and fixed to the frame. The voice coil bobbin is supported from the lower side. The resistance to input is improved without impairing the thinness of the speaker 1, and while suppressing the increase of the production cost.
