摘要： A sound output device is configured to be installed in a vehicle. The sound output device includes a driving-status detector for detecting a driving status of the vehicle, a sound signal generator for generating a reference signal in response to the detected driving status, first and second units for processing the generated reference signal, first and second sound output parts for outputting the reference signals processed by the first and second units. The first unit includes a phase shifter for shifting a phase of the reference signal such that the reference signals output from the first sound output part and the second sound output part have a phase difference between the respective reference signals. This sound output device allows a passenger at a predetermined position to hear the sound in a preferable condition.

摘要： An electromechanical converter has independent electric input sections. The output of an active noise reduction controller is inputted into an electric input section and the audio signal from an audio section is inputted into an electric input section. These are mechanically combined at a vibration section and the combined signal is radiated as a sound wave into the space. With such a structure, both the active noise reduction function and the audio reproduction function are realized without installing a large device in an existing audio reproduction apparatus.

摘要： An active noise controller can determine the signal transmission characteristics from the power amplifier and the speaker to the microphone without using any special external measuring instrument and calculate a cosine correction value and a sine correction value without using an external computer. The active noise controller uses the cosine correction value and the sine correction value to actively reduce vibrational noise. The measurement mode is selected on touch panel (3), and correction value calculator (22) calculates cosine correction value C0 and sine correction value C1 by using filter coefficients W0 and W1 which allow error signal e′(n) to approach zero. Memory (23) stores these values C0 and C1.

摘要： A car-borne sound system that reproduces a recorded multi-channel music source in the 5. 1 system or the like system into a natural sound environment in a room of an automobile. Conventionally, at a driver's seat or at a front passenger seat, a sound image of vocal sounds (singing voice) was locating deviated from the natural placement. The present sound system eliminates such unnatural sound image positioning. A front center signal and a front right and a front left signals, which include much of the vocal components, are added on to a rear right and a rear left signals so that rear speakers (106 and 107) also reproduce the vocal components. Thus the vocal sound image is placed and fixed in the central place to provide a natural listening environment.
