This summary is provided to introduce concepts relating to an electronic percussion instrument with a spider web-like sensor. Some embodiments of the electronic percussion instrument are further described below in the detailed description. This summary is not intended to identify essential features of the claimed subject matter, nor is it intended for use in determining the scope of the claimed subject matter.
The accompanying drawings are included to provide a further understanding of the disclosure, and are incorporated in and constitute a part of the present disclosure. The drawings illustrate embodiments of the disclosure and, together with the description, serve to explain the principles of the disclosure. It is appreciable that the drawings are not necessarily in scale as some components may be shown to be out of proportion than the size in actual implementation in order to clearly illustrate the concept of the present disclosure.
An electronic percussion instrument according to the present disclosure utilizes a novel vibration resonance member. The vibration resonance member senses resonates in response to sensing, via a resonance damping member, vibrations generated by a percussion member of the electronic percussion instrument when the percussion member is beaten, struck or otherwise percussed by a user. The vibration resonance member comprises a hub portion, a plurality of radial portions extending radially from the hub portion, and a plurality of spiral portions. Each of the spiral portions is disposed between and connects respective two of the radial portions. Each of the radial portions is connected to a respective adjacent one of the radial portions by one or more of the spiral portions. Accordingly, the vibration resonance member has a configuration that generally resembles a spider web, and acts as an effective sensor of vibration with its spider-web like configuration. The profile of the vibration resonance member may be adopted to fit the particular shape and size of the percussion member, e.g., a metallic plate or a combination of a metallic plate and a rubber pad, of the electronic percussion instrument. The resultant range of signal detection of a piezoelectric sensor of the electronic percussion instrument of the present disclosure is thus relatively large, i.e., covering most of the area of the percussion member, and the signal for generation of an electronic percussion sound is stable.
The percussion member 110 is configured to generate vibrations when percussed. For instance, the percussion member 110 may be a metallic plate such as, for example, a steel plate (e.g., when the electronic percussion instrument 100 is an electronic drum).

The vibration damping member 830 is disposed between and in direct contact with the percussion member 810 and the vibration resonance member 820, and is configured to propagate the vibrations generated by the percussion member 810 to the vibration resonance member 820.

In at least some embodiments, a width of at least one of the radial portions of the vibration resonance member 1400/1500/1600/1700/1800, as measured at two or more points along a radial direction with respect to the hub portion, may increase gradually from the hub portion toward a distal end of the at least one of the radial portions that is away from the hub portion.
In at least some embodiments, a radius of a first ring portion of the plurality of ring portions may be less than a radius of a second ring portion of the plurality of ring portions, and a width of the first ring portion may be less than the a width of the second ring portion.
In at least some embodiments, a shape of the vibration resonance member may be generally round.
In at least some embodiments, a diameter of the vibration resonance member may be between approximately 8 inches and approximately 16 inches. For example, the diameter of vibration resonance member 1400 may be approximately 8 or 10 inches, the diameter of vibration resonance member 1500 may be approximately 12 inches, the diameter of vibration resonance member 1600 may be approximately 13 inches, the diameter of vibration resonance member 1700 may be approximately 14 inches, and the diameter of vibration resonance member 1800 may be approximately 16 inches.
In at least some embodiments, a thickness of the vibration resonance member may be between approximately 0.3 millimeters and approximately 5.0 millimeters.
Compared to vibration resonance members 120, 620, 720 and 820, each of the vibration resonance members 1400, 1500, 1600, 1700 and 1800 has more radial portions, or stems. Advantageously, the increase in the number of radial portions, or stems, allows denser sound waves and more samples to be taken by the electronic sound generation unit within a given period of time, thus minimizes the likelihood of misjudgment of the force striking the percussion member.
Moreover, as the width of the ring portions increases, from a ring portion closer to the hub portion to a ring portion farther away from the hub portion, a downward sloped curve of sound waves from striking of the rim of the percussion member may be obtained, thus minimizing double trigger.
