Abstract
A stringed instrument, such as a semi-acoustic electric guitar, can employ a resonance system that consists of a body having at least one internal cavity accessed by a soundhole continuously extending from a top cover. The soundhole may have a continuously curvilinear transition from the top cover and a length corresponding with an altered resonance frequency of the instrument body.
Claims20
An apparatus comprising:
- an instrument body defining at least one internal cavity;
- and
- a soundhole attached to a soundhole rim of the instrument body via a notch in a top cover of the instrument body, the soundhole having a continuously linear sidewall and a continuously curvilinear sidewall extending a length into the instrument body to provide an altered resonance frequency of the instrument body.
A guitar comprising:
- an instrument body defining at least one internal cavity;
- a soundhole attached to a soundhole rim of the instrument body via a notch in a top cover of the instrument body, the soundhole having a first sidewall shape defined by a first continuously linear sidewall and a first continuously curvilinear sidewall extending a length into the instrument body to provide an altered resonance frequency of the instrument body;
- and
- an insert attached to the soundhole, the insert having a second sidewall shape defined by a second continuously linear sidewall and a second continuously curvilinear sidewall, the first sidewall shape being different than the second sidewall shape.
1 more element
An apparatus comprising:
- an instrument body defining at least one internal cavity;
- and
- a soundhole attached to a soundhole rim of the instrument body via a seam in a top cover of the instrument body, the soundhole having a continuously linear sidewall and a continuously curvilinear sidewall extending a length into the instrument body to provide an altered resonance frequency of the instrument body.
