Abstract
The utility model provides a capacitance type sensor for musical percussion instrument, comprising two corresponding conductive electrodes, wherein one conductive electrode is fixed and another conductive electrode is connected with the percussed vibration part. Under the premise of not increasing cost and installation complexity, the capacitance type sensor thoroughly denies the traditional piezoelectric ceramic sensing way and uses the capacitance type sensing way and detects the drum head vibration of various amplitudes by the electric field variance. Because the electric field is transferred without solid medium, the performance greatly precedes the traditional piezoelectric ceramic conduction vibration way. The percussion hand feeling of the electric drum is greatly increased, the capacitance type sensor is especially suitable for high-grade electric acoustic percussion instrument, with features of simple structure and good use effect.
Description
Technical field
The utility model relates to a kind of sensor, is mainly used in to hit the class electrophonic musical instrument.Electronic drum particularly.
Background technology
In hitting electrophonic musical instrument, need the sensor that stroke signal is converted to electric signal.Traditional sensor generally uses piezoelectric ceramics as core parts, transfers vibrations to piezoelectric ceramics by certain conductive material, is discerned in order to produce electric signal, and is sent to the source of sound device after treatment, sends various percussive sounds.Advantages such as it is simple, with low cost that traditional piezoelectric ceramics structure has principle, easy for installation, but its defective is also arranged: the strike homogeneity is not good enough.
The utility model content
The purpose of this utility model is exactly to hit defectives such as sensor rapid wear, inconvenience, frequency response range traditional in the electrophonic musical instrument are not enough in order to overcome, and a kind of strike good uniformity, sensor firmly and easily are provided.
The purpose of this utility model can realize by following scheme: comprise two corresponding conductive electrodes, one fixing, and another links together with the vibrating mass (as drum) that is impacted.
The utility model has thoroughly been abandoned traditional piezoelectric ceramics sensing mode, and has been adopted condenser type not increasing cost and installing under the prerequisite of complexity, detects the bulging surface vibration of various amplitudes by electric field change.Because the transmission of electric field does not need solid dielectric, so be better than traditional piezoelectric ceramics conduction vibration mode on the performance greatly.Can improve the strike feel of electronic drum greatly, thereby be specially adapted to high-grade electroacoustic percussion instrument.Have simple in structure, characteristics such as result of use is good.
Description of drawings
Fig. 1 the utility model user mode structural representation
Embodiment
Contrast Fig. 1 as can be known, the utility model comprises two corresponding conductive electrodes 1 and conductive electrode 2, conductive electrode 2 is fixed on the collets 5, conductive electrode 1 is installed in the back side of bulging face 4, each electrode all is connected with the lead 3 of energising usefulness, the conductive electrode 1 that is installed in the back side of bulging face 4 is the electrode foil plate of being made by flexible material, can not influence bulging strike feel like this.
Principle of work of the present utility model is as follows: the utility model is to utilize electric capacitance change to detect the vibration signal of bulging face.When work, two electrodes fill with certain electric charge.During the vibrating mass vibration, cause electric capacitance change, mimic channel can be according to the variation of electric capacity, and the electric signal that produces respective change after the Filtering Processing, is converted to digital signal by ADC through amplifying, and transfers to CPU and handles.
Concrete enforcement of the present utility model is not limited to top described form, for example, electric capacity can be revolved and turn 90 degrees, and an electrode is motionless, and another electrode is connected on the drum, and two electrode distances do not change with the drum vibration, but two electrodes change over against area.Also can face be whole makes with metal film with drum, constitute an electrode.Its ultimate principle all is the same: utilize the variation of electric capacity to detect bulging surface vibration.
