摘要： A high pass filter 32 having a cut-off frequency of 200 Hz and a cut-off response of +12 dB/OCT and a low pass filter 33 having a cut-off frequency of 400 Hz and a cut-off response steeper than −24 dB/OCT are used to pick out components in a double overtone region of 200˜400 Hz of a bass musical instrument such as a base or a bass drum from an input audio signal. The component which is picked out is input to distortion applying means 34 having an input-output response which is a non-linear response having no point symmetry with respect to 0 point, thus applying a distortion to cause even-numbered overtone components to be produced. An output from the distortion applying means 34 and the input audio signal are summed in a summer 18 to be delivered. Natural tones which have boosted bass tones and which are free from impurity are obtained.

摘要： A pressure point detector has a simple structure and is capable of detecting which location of a two-dimensional surface such as a circle a pressure is applied can be detected. The pressure point detector includes a flexible insulation member in a predetermined shape, a resistance film formed on one side of the flexible insulation member, a conductive member made of conductive material and established to face the insulation member with a with a predetermined gap therebetween, and a pair of electrodes established on the resistance film in a parallel fashion to produce voltage distribution. The pressure point detector produces an output voltage from the conductive member indicative of a location of the pressure applied to the insulation member.
