摘要： An acoustic apparatus comprises a cabinet, and a loudspeaker unit and a driving apparatus disposed in the cabinet. The acoustic apparatus is driven by an external power amplifier which normally constant-voltage-drives a conventional loudspeaker. The driving apparatus has a power amplifier circuit and a transfer function control circuit, and drives the loudspeaker unit in cooperation with the external power amplifier. The driving apparatus generates an electric energy corresponding to an increase in energy from that which is required in a normal constant-voltage-driving, the increase being produced by an operation of the transfer function control circuit, and the generated energy is inputted to the loudspeaker unit. By means of the above, when the acoustic apparatus is driven by the external power amplifier, an internal resistance of the loudspeaker unit is substantially cancelled or reduced, and an improvement of the electro-acoustic transducing characteristics of the loudspeaker unit or a loudspeaker system is achieved.

摘要： The dynamic loudspeaker driving apparatus consists of at least a power amplifier and a feedback circuit. The power amplifier amplifies an input signal so that the dynamic loudspeaker is driven by the amplified input signal. A detecting circuit is further provided in order to accurately detect a motional voltage produced at an equivalent motional impedance of dynamic loudspeaker, and the feedback circuit negatively feedbacks the detected motional voltage to the power amplifier so that distortions due to a transient response of a vibration system of dynamic loudspeaker will be eliminated. The amplified input signal is supplied to a first terminal of dynamic loudspeaker and a voltage at a second input terminal of dynamic loudspeaker is supplied to the feedback circuit, and impedance components other than the equivalent motional impedance can be canceled. In addition, it is possible to be further provided with a filter circuit having a frequency response characteristics which can be obtained by electrically simulating a voltage transmission characteristic against the equivalent motional impedance of dynamic loudspeaker. Thus, the input signal can be given with a desirable frequency characteristic by the filter circuit and then supplied to the power amplifier.

摘要： An amplifier circuit which amplifies an input signal with substantially zero distortion and can stably operate even at high frequencies is provided. A signal proportional to an input signal supplied to an input terminal is applied to an input terminal of a main amplifier. An output signal of this main amplifier is supplied through an impedance circuit to one of input terminals of a differential amplifier the other input terminal of which is supplied with the input signal to be amplified. An output signal of this differential amplifier is fed to a reference voltage input terminal of the main amplifier to determine a voltage potential of the input terminal of the main amplifier when a signal level of the input signal is zero, thereby distortion generated in the main amplifier being canceled.
