摘要： A sound reproducing apparatus which can be relatively inexpensive as a whole and also be simple in construction with reduced wiring even in the case where many speakers are used. Pulse-width modulated (PWM) pulses are generated based on respective audio signals for multiple-channel speakers. PWM pulses are time-division multiplexed and amplified, and then output as digital driving signals. The multiple-channel speakers are selectively turned on/off such that the digital driving signals are supplied to the respective multiple-channel speakers of corresponding channels.

摘要： There is provided a musical tone generation control system which enables the user to obtain a feeling of operation as well as to obtain a feeling of satisfaction as if he or she were aggressively participating in performance or playback of a musical composition or the like. The musical tone generation control system has at least one operating terminal that can be carried by an operator. Each operating terminal detects a motion of the operating terminal caused by an operation of the operator, generates motion information based on the detected motion, and transmits the generated motion information to the musical tone generation control apparatus. A musical tone generation control apparatus including a tone generating apparatus that generates musical tones generates performance control information for controlling musical tones generated from the tone generating apparatus based on the received motion information, generates vibration control information based on the generated performance control information, and transmits the generated vibration control information to the operating terminal. The operating terminal generates a vibration corresponding to the received vibration control information.

摘要： An automatic grinding apparatus for wood working comprising means for maintaining substantially constant the contact pressure between a grinding wheel and a material to be ground and the peripheral speed thereof irrespective of abrasion of the grinding wheel. The means for maintaining the contact force constant comprises a grinding wheel swinging means and a grinding wheel compensating means. The former includes a swing arm pivotally mounted on a slider for swinging movement and carrying rotatably a grinding wheel shaft at the free end, and a cylinder means for swinging the swing arm toward and away from the material. The latter includes a means for detecting the angular displacement of the swing arm due to abrasion of the grinding wheel and a slider moving means for advancing the slider toward the material until the swing arm restores to its initial angular position. The means for maintaining the peripheral speed of the grinding wheel constant includes a self-adjusting pulley at the driven side which is so designed that change in the distance between both drive and driven shafts due to the forward movement of the slider causes decrease in the effective diameter of the pulley to increase the speed of the grinding wheel.

摘要： In a masking sound generation apparatus, a CPU analyzes a speech utterance speed of a received sound signal. Then, the CPU copies the received sound signal into a plurality of sound signals and performs the following processing on each of the sound signals. Namely, the CPU divides each of the sound signals into frames on the basis of a frame length determined on the basis of the speech utterance speed. Reverse process is performed on each of the frames to replace a waveform of the frame with a reverse waveform, and a windowing process is performed to achieve a smooth connection between the frames. Then, the CPU randomly rearranges the order of the frames and mixes the plurality of sound signals to generate a masking sound signal.

摘要： A hands-free loudspeaker system which is capable of achieving high-quality voice amplification without requiring a human speaker to move to a microphone or a microphone to be moved to a human speaker. A microphone whose input level has continued to be above a threshold value for not shorter than a predetermined time period is detected, based on input signals from dispersedly arranged microphones. An input signal from the microphone is selected and outputted to a loudspeaker at an output level or with a delay time, according to a location of the loudspeaker. A preset lowest threshold level is initially set to the threshold value, and an input level of the microphone higher than the threshold value is newly set to the same, while when the input level is lower than the threshold value, a lower value is set to the same in a step-by-step manner.
