Patent Number Title Of Patent Date Issued
6563033 Stringed musical instrument with apparatus enhancing low frequency sounds May 13, 2003
A stringed instrument such as a guitar with a thinner than traditional body is provided enhanced decibels measured by sound pressure level (DBSPL) response employing a combination of one or more of each of a passive radiator, tuned isolated resonating wave guide or guides in the body
5659155 Acoustical transducer enclosure August 19, 1997
The purpose of the invention is to direct, in a coherent fashion, audible frequencies, particularly, low frequencies and especially those below 90 cycles. The advantage to directing low frequencies to acute projection patterns previously thought impossible is to reduce low frequency feed
