    摘要: After a DC erasing is performed in a direction by permanent magnets on a servo signal recording part, servo signals are recorded in the signal recording area of the servo signal recording part by a magnetic field in the direction opposite to that of the DC erasing. Thus, in a recording method for a magnetic recording medium having a data signal recording part and the servo signal recording part on a magnetic layer, accurate servo signals can be recorded and reproduced even on the medium having the magnetic layer of 0.13 μm or smaller.

    摘要: An enclosure of a cellular phone is formed with a plurality of sound releasing holes. The inside of a portion where the sound releasing holes are provided defines an air chamber formed with a receiving portion for mounting a piezoelectric sounding element. The piezoelectric sounding element is of bimorph structure formed by adhering piezoelectric elements on both surfaces of a diaphragm, and serves as a speaker by hermetically fixing a peripheral edge of the diaphragm to the receiving portion. Acoustic characteristics of such a piezoelectric sounding body relates to the total sum S of side surface areas of the sound releasing holes. Therefore, by setting the total sum to a value from 1.5 mm to 60 mm2, variations in resonant frequency and lowering of the sound pressure are prevented, and hence the required acoustic characteristics can be secured while realizing reduction of the thickness of the wall of the enclosure.

The piezoelectric member consists of either laminated piezoelectric layers or a monolayer. A thickness ratio LC/LA of the piezoelectric member 10 ranges from 0.01 to 0.06, more preferably, 0.02 to 0.05, thereby resulting in an enhanced efficiency, wherein LA and LC refer to a length and a thickness of the piezoelectric member 10, respectively.
