Abstract: A loudspeaker includes a diaphragm and an edge having an inner periphery end portion thereof connected with an outer periphery of the diaphragm, in which an outer end portion of the edge is attached to a speaker frame. The diaphragm has a bent portion in the vicinity of a border at the inner periphery side of a connecting portion connecting the diaphragm with the edge. A reinforcing portion is formed on the bent portion in order to reinforce the bent portion. It is, therefore, possible to disperse or reduce various forces applied to the bent portion, and to prevent strength deterioration or damage of the diaphragm even when sound signals having large amplitude are applied to the loudspeaker. As a result, it is also possible to prevent deterioration of acoustic characteristics.

Abstract: A thread winding part or a reinforcing wire winding part is formed by winding a heat resistant fiber thread or a reinforcing wire around the voice coil bobbin in contact with both coil ends of the wire winding part or a coil end of the same on a magnetic-circuit side. A bent part bent outward is formed on the lower end of the voice coil bobbin on the magnetic circuit side. This prevents the wire winding part from shifting from its mounting position and from coming off to the lower side. In the resulting voice coil, the wire winding part hardly comes off the voice coil bobbin even if the wire binding of the wire winding part is loosened by Joule heat, speaker vibrations, etc.

Abstract: A liquid ejection apparatus for accurately supplying a plurality of nozzle rows with liquid having an adjustable hydrodynamic flow pressure to eject the liquid.

The character member comprises a plurality of character bodies which are connected by coupling portions and which comprise dot-like projections which form dot characters. The small printer also has a device to rotate the character member in order to place a desired dot character body which contains the dot character to be printed between a hammer and a piece of paper. Subsequently, the hammer strikes the desired character body and the dot character is printed on the paper. Since the small printer has the above-described construction, the small printer is less expensive and smaller than conventional printers.
