A rim raising device attaches to a drum rim, or operates remotely from a drum. The device provides additional elevation above the drum, and increased surface area to a section of the drum rim such that a percussion technique is enhanced. The increased elevation provides space for other components to attach to the drum rim. A trigger assembly comprises at least one piezoelectric sensor and/or at least one force sensor that detect the force. The piezoelectric sensor generates an intensity sensitive signal. The force sensor generates an on/off, linear signal that produces sound, or serves as a gate for the piezoelectric sensor. The force converts into both types of signals, and wirelessly transmitted to a sound module for generating a predetermined sound. A transmitter on the device uses wireless technology, or an instrument cable/wire to transmit the signal. A vibration suppression portion inhibits interferences and other unwanted vibrations. |

1. A rim raising device for enhancing a percussion technique on a drum rim, comprising:
an arc section, the arc section being configured to replace an existing drum rim for enabling a more comfortable and natural grip on at least one drum stick when performing a percussion technique, and for enhancing a sound generated by striking a drum with the at least one drum stick; the arc section comprising a contact portion, the contact portion being configured to engage the at least one drum stick and/or a body part, the arc section further comprising a mounting portion, the mounting portion being disposed to mount the arc section on a mounting surface, the arc section further comprising a sidewall, the sidewall being configured to elevate the contact portion over a circumference of the mounting surface, wherein the contact portion is spaced apart vertically above the mounting surface for creating an air space between the contact portion and the mounting surface; a triggering assembly, the triggering assembly being configured to detect a force on the contact portion and perform a predetermined action for generating a predetermined sound, the triggering assembly comprising at least one piezoelectric sensor, the at least one piezoelectric sensor being configured to convert the force into an intensity sensitive signal that is proportional to an intensity of the force, the triggering assembly further comprising at least one force sensor, the at least one force sensor being configured to convert the force into a linear signal that is either on or off, the at least one force sensor further being configured to actuate the at least one piezoelectric sensor in response to the force, the triggering assembly further comprising a transmitter, the transmitter being configured to transmit the intensity sensitive signal and/or the linear signal to a remote trigger interface, the remote trigger interface being configured to convert the intensity sensitive signal and/or the linear signal into an acoustic energy for generating the predetermined sound; wherein the intensity sensitive signal and the linear signal generate different acoustic energies; and a vibration suppression portion, the vibration suppression portion being configured to help suppress a vibration from the force. |
