Abstract: PURPOSE:To improve detection sensitivity with a rather simple constitution by locking a master laser beam and a slave laser beam through frequency offset. CONSTITUTION:Against a master laser diode 82, a slave laser diode 84 is made to offset only by predetermined frequency and to lock. And thereby, at a laser Doppler speedometer 80, a slave laser beam L7 can be maintained to be fre quency that is offset only by frequency omega against frequency which is one of components of a master laser beam L6. Consequently, a measurement beam with much intensified beam strength can be obtained and measuring sensitivity can be improved by such extent thereof.

Abstract: PURPOSE:To improve an S/N of a beat signal noticeably along with a higher detection sensitivity by performing a phase modulation of a first laser light emitted from one end face of a semiconductor laser to generate a reference light. CONSTITUTION:While a reference light L5 is generated by a laser light L2 emitted at one end of a semiconductor laser 42, a laser light L1 emitted at the remaining one end irradiates an object 19 to be measured to generate a measuring light L7. Here, an optical path of the laser light L1 is separated from that of the measuring light L7. As a result, an intensity of the measuring light L7 can be improved while the mixing of non-modulation laser light and the return of the reflected light to the semiconductor laser 42 can be avoided effectively thereby improving an S/N of a beat signal FM1 noticeably along with a higher detection sensitivity.

Abstract: PURPOSE:To highly precisely obtain a measuring result by modulating a light modulator by a sine wave modulating signal to form a reference light beam and measuring a speed on the basis of the light beam thereof. CONSTITUTION:A light source beam LA1 emitted from a laser light source 4 is modulated in light modulator 12 by a sine wave modulating signal S2 and a reference light beam LA3 is formed thereby. A reflecting light beam LA4 which is obtained by irradiating the beam LA1 on the vibrating surface of a speaker 3 is guided to a light detecting element 21 together with the beam LA3 and a light detecting signal So is obtained from the element 21. Components in which the angular frequency omega3 of the signal S2 of the signal So is made a center frequency is input in a countable circuit 39 through a BPF 30 and the components 30 in which 2omega3 is made a center frequency is extracted in a BPF 31 and input in a circuit 39 after they are converted into a low area in a multiplicating circuit 32. The output which corresponds to a vibrating speed of a speaker 3 from the circuit 39 can be obtained.

Abstract: PROBLEM TO BE SOLVED: To provide a loudspeaker device for reproducing a sound by adding vibrations to an acoustic diaphragm by an actuator so that an audio image spreads uniformly in the entire surface of the acoustic diaphragm and the entire loudspeaker is made compact.
SOLUTION: A rectangular hole 12 is formed in a flat acoustic diaphragm 10, and a magnetostrictive actuator 30 is mounted to the rectangular hole 12 so that an angle α to an extended direction of an outer end face 11a of the acoustic diaphragm 10 in the driving axis direction shown by an arrow 1 becomes a non-right angle. When the magnetostrictive actuator 30 is driven by a sound signal, vibrations of longitudinal waves are added to a point Pa of the acoustic diaphragm 10. The longitudinal waves become mixed waves of longitudinal waves and transverse waves in a process that the longitudinal waves are propagated to the outer end face 11a, and the transverse waves are emitted as sound waves in a direction vertical to a face of the acoustic diaphragm 10. As the angle α is a non-right angle, resonation by the longitudinal waves reflected on the outer end face 11a is reduced.
