    • A table-type electronic percussion instrument is constructed by a table board, legs, pads as well as a musical tone generation circuit and a speaker system. Herein, the table board has a specific shape such as a pentagon-like shape which enables multiple persons to seat. The table board is supported by the legs and is constructed by a base material having a high rigidity and a dressing board like a plywood. The dressing board covers a surface of the base material through which holes are formed. The pads are arranged on a surface of the dressing board to match with locations of the holes. Sensors are provided inside of the holes and are attached to a backside of the dressing board. So, the sensors are arranged to detect striking force which is imparted to each of the pads by the persons. The musical tone generation circuit is provided beneath the table board to convert electric signals of the sensors to musical tone signals. The speaker system is located beneath the table board to generate musical tones (e.g., percussion sounds) based on the musical tone signals. For example, if the pads act like electronic drums and/or electronic cymbals, the speaker system generates drum sounds and/or cymbal sounds when the pads are struck by the persons. Thanks to the table-like construction, the electronic percussion instrument is shared by multiple persons to play an ensemble. Incidentally, the musical tone generation circuit contains a mixing circuit which performs mixing operations on the musical tone signals corresponding to the pads and other musical tone signals supplied thereto. So, the musical tone generation circuit outputs mixed musical tone signals, based on which the speaker system generates mixed musical tones.
    • 台式电子打击乐器由桌面板,腿,垫以及乐音发生电路和扬声器系统构成。 这里,台板具有能够使多人坐下的五边形状的特定形状。 台板由腿部支撑,并且由具有高刚性的基材和像胶合板的修整板构成。 修整板覆盖形成孔的基材的表面。 衬垫布置在敷料板的表面上以与孔的位置匹配。 传感器设置在孔的内部并附着在修整板的背面。 因此,传感器被布置成检测由人员赋予每个垫的击打力。 乐谱产生电路设置在桌面下方,以将传感器的电信号转换为乐音信号。 扬声器系统位于台板下方,以基于乐音信号产生乐音(例如打击乐)。 例如,如果垫片像电子鼓和/或电子钹那样起作用,当垫子被人撞击时,扬声器系统产生鼓声和/或钹声。 由于采用了桌面式的结构,电子打击乐器由多人共同演奏。 顺便提及,乐音产生电路包含混合电路,该混合电路对与所述音垫对应的乐音信号和提供给其的其它乐音信号进行混音操作。 因此,乐音产生电路输出混合的乐音信号,由此扬声器系统产生混合的乐音。

    • A musical tone signal generation apparatus accommodated for multiple users to play music in an ensemble is configured by a main unit and a prescribed number of performance operators, which are physically separated from each other. The main unit installs speakers that are arranged in connection with the performance operators respectively. At least one of the performance operators is configured as a hold operator that is configured using a pressure sensor mounted on a base member and encapsulated in a hold member which is made by elastic material (e.g., urethane foam) and is formed in a round shape suited for grip of the user. Each of other performance operators installs at least a pad, which is manually operated by each user to issue tone-generation instructions. Performance data (e.g., MIDI data) and tone color data are provided with respect to at least a single musical tune constructed by plural parts respectively corresponding to plural tone colors, which are automatically assigned to the performance operators. Herein, musical tone signals are automatically generated based on the performance data to play automatic performance, or musical tone signals are generated in response to tone-generation instructions being issued from the performance operator to play manual performance by the user. Moreover, the main unit installs a control panel having indicators and switches for prescribed functions and elements in music play such as play, stop, fast forward, reverse, tone volume, tempo and modulation, while the performance operator installs a sub panel having a limited number of switches.
