Abstract
The invention provides a capacitive-type sensor for striking an electronic musical instrument, comprising two corresponding conductive electrodes of which one is fixed and the other one is connected with a stricken vibration member. The invention completely abandons the traditional piezoelectric ceramic sensing way and adopts the capacitive type to detect the drumhead vibration at various amplitudes through the variation of electric fields under the condition of not increasing the cost and the mounting complexity. Since the electric fields can be transferred without a solid medium, the performance of the capacitive-type sensor is further superior to the traditional piezoelectric ceramic conductive vibration way. The invention can greatly improve the striking feeling of electronic drums and is particularly suitable for a high-grade electronic musical instrument. The invention has the characteristics of simple structure, good use effect, and the like.
Description
Technical field
The present invention relates to a kind of sensor, be mainly used in and 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.
Summary of the invention
Purpose of the present invention 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.
Purpose of the present invention 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 present invention has thoroughly abandoned traditional piezoelectric ceramics sensing mode, and has 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 user mode structural representation of the present invention
Embodiment
Contrast Fig. 1 as can be known, the present invention includes 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 invention is as follows: the present invention utilizes 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 invention 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.
Claims (2)
1. capacitance type sensor that is used to hit electrophonic musical instrument, it is characterized in that comprising 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), and each electrode all is connected with the lead (3) of energising usefulness.
