The utility model content

The purpose of this utility model is for a kind of highly sensitive, bandwidth, long percussion instrument sound pick up equipment of life-span are provided.

For achieving the above object, percussion instrument sound pick up equipment of the present utility model and electronic percussion instrument, as the electronics drum kit, the electronic percussion plate, the happy exercising machine of electronics cooperates realizes the pickup function, this percussion instrument sound pick up equipment comprises the Piezoelectric film Vibrating Sensors that is used for pickup, analog to digital conversion circuit, microcontroller circuit, source of sound IC circuit, D/A converting circuit, the pronunciation power amplifier, loudspeaker, this Piezoelectric film Vibrating Sensors comprises electrode pin or crimp type terminal, have certain flexible piezoelectric membrane and mass, the electrode pin or the crimp type terminal of this Piezoelectric film Vibrating Sensors are fixedlyed connected with percussion instrument, the other end is fixedlyed connected with mass, and the piezoelectric membrane of this Piezoelectric film Vibrating Sensors is a polyvinylidene difluoride film.

Because the Piezoelectric film Vibrating Sensors of percussion instrument sound pick up equipment of the present utility model is not fragile, sensitive more, and can change the resonance frequency of piezoelectric membrane selectively by the quality size that changes mass, the position that this Piezoelectric film Vibrating Sensors is combined with percussion instrument also becomes unrestricted, can be located at the upside or the downside of the idiophonic scope of attack according to the actual needs neatly, or be located at idiophonic vibration source position, perhaps be located on the idiophonic housing.

Beneficial effect, because percussion instrument sound pick up equipment of the present utility model has adopted by electrode pin or crimp type terminal, has had the structure that certain flexible piezoelectric membrane and mass constitute, pin or crimp type terminal one end are fixedlyed connected with percussion instrument, the other end is provided with mass, change the resonance frequency of piezoelectric membrane selectively by the quality that changes mass, therefore this percussion instrument sound pick up equipment has highly sensitive, the advantage that bandwidth and resonance frequency are adjustable guarantees that this percussion instrument sound pick up equipment has better pickup effect.

Relevant detailed content of the present utility model and technology are elaborated with regard to the accompanying drawing that cooperates specific embodiment now.
