Abstract: PROBLEM TO BE SOLVED: To solve the problem that energy loss is large and linearity in conversion from a sound signal into an acoustic wave is damaged since rotation driving force of a motor is converted into reciprocal driving force on a straight line and a diaphragm is vibrated by reciprocal driving force although a speaker system where the diaphragm is compulsorily vibrated by driving force and the acoustic wave is generated while rotation of the dynamo-electric motor is reciprocally reversed is proposed.
SOLUTION: The speaker system S1 is provided with a volume variable part V1 and a first rotation driving means M1. The volume variable part V1 has a first member B1 and a second member D1. The first member B1 is supported so that it can be displaced in a circumferential direction with a rotation center axis as a center. The first member B1 is relatively displaced in the circumferential direction with respect to the second member D1. Thus, the volume on a front side of the volume variable part V1 changes. The first rotation driving means M1 fluctuates the first member B1 in the circumferential direction of the rotation center axis. Thus, the volume of a front side of the volume variable part V1 is increased and decreased and the acoustic wave is generated.

Abstract: PROBLEM TO BE SOLVED: To control a sound pressure level (polar pattern) in every loudspeaking direction. SOLUTION: A sound outputted from a speaker driver 2 is fed to a horn 4 formed to be nearly flat through a sound guide pipe 3 and the sound is sounded from an opening 45 of the horn 4. Moreover, the sound guide 3 is coupled with an upper face of the horn 4 and the shape of the coupled part is formed to be a slender rectangle. Thus, it is equivalent to it that a straight line sound source, that is, a linear sound source is formed as a sound supply source to the horn 4. In this state, the loudspeaking distribution of sound emitted from the linear sound source, that is, the directivity is changed by changing the coupling position and the coupling angle or the like of the sound guide 3 with respect to the horn 4.

Abstract: PURPOSE:To accurately extract a displacement of a vibration part of a speaker with simple configuration. CONSTITUTION:A conductive bobbin 46 and a cone 62 are vibrated in the direction of the arrow mark A in response to an electric signal inputted to a voice coil 48 wound on the bobbin 46 of a cone speaker unit 20. A fixed electrode 66 is fixed in the bobbin 46 along the lengthwise direction confronting with the bobbin 46 with an interval. The opposite area between the bobbin 46 and the fixed electrode 66 is fluctuated by the vibration of the bobbin 46, and a capacitance of a capacitor comprising the fixed electrode 66 and the bobbin 46 is changed proportional to a displacement of the bobbin 46. The change is extracted through a lead wire 70 and a lead wire connecting to the bobbin 46.

Abstract: PURPOSE:To provide the foot monitor speaker system capable of feedback with reproduced sounds satisfactory to a listener by providing an electric correction means which raises the acoustic pressure in a specific frequency relatively to that of the other frequency. CONSTITUTION:An input signal has the band divided by a low-pass filter 1 and a high-pass filter 2, and a floor correction equalizer 3 is inserted into the side of the low-pass filter 1 to compensate an influence of floor reflection. A changeover switch 5 is provided to bypass the equalizer 3 at the time of not requiring this compensation. An equalizer 4 on the side of the high-pass filter 2 has a function to raise the high band part of the frequency characteristic. The signal is amplified by amplifiers 6 and 7, and sounds are produced from a woofer 8 and a tweeter 9. Thus, dip does not occur in the acoustic pressure of the specific frequency by synthesis of direct sounds and reflected sounds from the floor, and feedback is performed with reproduced sounds satisfactory to the listener.

Abstract: PROBLEM TO BE SOLVED: To provide a thin double-sided speaker allowing a user to tilt each of the high-bandwidth sounds output from the both sides to a desired direction.SOLUTION: A thin double-sided speaker includes: a large number of linear pattern 12 corresponding to a neutral zone of a permanent magnet plate formed on a diaphragm disposed between two units of the permanent magnet plates; and two sound emitting surfaces for emitting sounds to the opposite direction from each other. The diaphragm is divided into two or more vibration areas 15a and 15b, and wiring patterns 11a and 11b connected to linear patterns 12 are formed for each of the vibration areas 15a and 15b. Consequently, if driving signals of different delay time are provided with respect to the wiring patterns 11a and 11b, the orientation of the two sound emitting surfaces can be tilted to the same direction with respect to the front direction.
