Description
Technical field
Electronic percussion instrument manufacturing technology field is the utility model is related to, especially, is related to a kind of electronic percussion instrument and hits
Beat position detecting device.
Background technology
Mainly there is the following two kinds in the detection method of the identification impact position of current electronic percussion instrument：(1) film is used
Switch sensor does impact position detection, for example places a thin film switch sensor in the drum side position of electronic drum, when hitting
Beat a drum side position when, thin film switch sensor connect, detection chip detect thin film switch sensor connect, this can be judged
The position of secondary impact is drum side position, and when impacting drum surface, detection chip does not detect that thin film switch sensor is connected, then
The position of impact can be judged for drum surface position.(2) impact position detection is done using piezo, such as respectively in electronic drum
A piezo detection impact signal is respectively placed in drum surface and drum side position, and when beating drum side, detection chip, which detects, to be placed on
The piezo output signal on drum side and the piezo output signal ratio relation for being placed on drum surface, can determine whether this time to hit after processing
The position beaten is drum side, and when impacting drum surface, detection chip detects the piezo output signal for being placed on drum surface with being placed on
The proportionate relationship of the piezo output signal on drum side, the position that this time impact is can determine whether after processing is drum surface.
But both the above detection method has shortcoming：(1) impact position detection is done using thin film switch sensor：To device
The requirement of part and assembling is high, if thin film switch sensor has slight deformation or appearance not to develop the assembling such as whole and miss in assembling
When poor, easily cause thin film switch sensor to be failed because of short circuit, cause detection chip to judge impact position by accident.(2) buzzing is used
Piece does impact position detection：To structure design, the requirement of piezo device assembling is high, effectively to isolate each impact position
Vibration interference, the requirement to Design of Mechanical Structure is very high, in the error crossed in kind of assembling, easily causes and is placed on each hit
It is inconsistent to beat the piezo output signal of position, causes detection chip to judge impact position by accident, while this mode cannot identify
The multiple hit positions in edge.
Utility model content
The utility model purpose is to provide a kind of electronic percussion instrument impact position detection means, to solve prior art
Middle impact position judges inaccurate technical problem.
To achieve the above object, the utility model provides a kind of electronic percussion instrument impact position detection means, including：Drum

Further, the strain transducer is bonded in the drum circle.
Further, the strain transducer is at least provided with one.
Further, it is provided with signal detection amplifying circuit in the signal supervisory instrument.
The utility model has the advantages that：A kind of electronic percussion instrument impact position detection dress of the present utility model
Put, the structure is by setting strain transducer, signal supervisory instrument and output circuit plate so that when impacting cushion rubber, strain passes
Sensor deforms upon, and resistance value changes, and signal supervisory instrument is converted to the change of resistance value the change of electric signal, passes through
The electric signal output of change is identified impact position by output circuit plate to detection chip, detection chip energy accurate judgement, detection
To the change of electric signal, then the position that can be determined that impact is the edge of drum；When impacting drum surface, strain transducer will not be sent out
Raw deformation, detection chip can't detect the change of electric signal, then the position that can be determined that impact is drum surface position so that the dress
It is relatively low to put matching requirements, does not have to worry slight deformation in assembling or does not develop the assembly problem such as whole, be advantageous to efficient batch
Production；The difficulty of Design of Mechanical Structure is reduced, substantially increases the degree of accuracy of the detection chip to identification impact position.
