Abstract
An apparatus and method for producing sound, particularly unusual sound effects, wherein the apparatus comprises at least one diaphragm and a spring attached to the diaphragm, having a lowest resonance frequency less than 18 hertz. The apparatus includes a resonator affixed to the diaphragm. According to the method of the invention, sounds are produced on an instrument having a spring and a diaphragm connected to the spring by exciting an echophone frequency of the spring by either activating longitudinal motion of the spring, jerking at least one end of the spring in a longitudinal direction, longitudinally displacing and releasing a section of the spring, and moving at least one end of the spring longitudinally in a rhythmic motion to excite an echophone frequency.
Claims16
An apparatus for producing sound effects comprising:
- two diaphragms;
- a resonator affixed to each diaphragm;
- a helically-coiled spring positioned between and attached to the diaphragms whereby said diaphragms can be moved with respect to each other to induce spring, diaphragm, and resonator vibrations, said spring having a lowest resonance frequency less than 18 hertz;
- and
- at least one support member affixed to each resonator whereby each resonator can be supported vibrations without substantially muffling the vibrations of each resonator.
An apparatus for producing sound effects, comprising:
- at least one diaphragm;
- a resonator affixed to the diaphragm;
- a spring attached to the diaphragm, said spring having a lowest resonance frequency less than 18 hertz;
- and
- at least one support member affixed to the resonator whereby the resonator can be supported without substantially muffling the vibrations of the resonator.
A method for producing sounds on an instrument including at least one diaphragm, a resonator affixed to the diaphragm, a spring attached to the diaphragm so that said diaphragm and said spring can be moved with respect to each other to induce spring and diaphragm vibrations, said spring having a lowest resonance frequency less than 18 hertz, and at least one support member affixed to the resonator, whereby the resonator can be supported without substantially muffling the vibrations of the resonator, comprising:
- exciting an echophone frequency of the spring by the activating longitudinal motion of the spring.
A method for producing sounds on an instrument including at least one diaphragm, a resonator affixed to the diaphragm, a spring attached to the diaphragm so that said diaphragm and said spring can be moved with respect to each other to induce spring and diaphragm vibrations, said spring having a lowest resonance frequency less than 18 hertz, and at least one support member affixed to to the resonator, whereby the resonator can be supported without substantially muffling the vibrations of the resonator, comprising:
- exciting an echophone frequency of the spring by jerking at least one end of the spring in a longitudinal direction.
A method for producing sounds on an instrument including at least one diaphragm, a resonator affixed to the diaphragm, a spring attached to the diaphragm so that said diaphragm and said spring can be moved with respect to each other to induce spring and diaphragm vibrations, said spring having a lowest resonance frequency less than 18 hertz, and at least one support member affixed to the resonator, whereby the resonator can be supported without substantially muffling the vibrations of the resonator, comprising:
- exciting an echophone frequency of the spring by longitudinally displacing a section of the spring from a rest position, and allowing the longitudinally displaced section to return to and beyond the rest position.
A method for producing sounds on an instrument including a spring having a lowest resonance frequency less than 18 hertz and a diaphragm connected to the spring, a resonator affixed to the diaphragm, and at least one support member affixed to the resonator, comprising:
- positioning the diaphragm to stretch the spring so that no two adjacent coils of the spring are in contact with each other;
- and
- moving at least one end of the spring longitudinally to excite an echophone frequency.
