Patent ID: 8901404

Claim:
A sound adjusting system, comprising: a sound-signal generating circuit configured to generate a sound signal; at least one speaker configured to emit sound in accordance with the sound signal generated by the sound signal generating circuit; a speaker accommodating body which accommodates, in an inner space thereof, the at least one speaker; and at least one resonator disposed in the speaker accommodating body, wherein the speaker accommodating body includes a sound emission path by which the sound emitted by the at least one speaker is introduced to an exterior of the speaker accommodating body via the inner space so as to permit the sound to propagate to the exterior, wherein a control point of the at least one resonator is located at a position corresponding to an antinode of a sound pressure in a natural vibration mode at a specific frequency generated in the inner space by driving of the at least one speaker, wherein the at least one resonator resonates at the specific frequency so as to adjust the sound pressure in the natural vibration mode at the specific frequency, whereby the sound is emitted from the sound emission path to the exterior of the speaker accommodating body, wherein the at least one resonator is formed of a tubular body in which one of longitudinally opposite ends thereof is closed so as to provide a closed end portion and the other of the longitudinally opposite ends thereof is open so as to provide an open end portion, and wherein the at least one resonator is disposed such that the open end portion is located at the position corresponding to the antinode of the sound pressure in the natural vibration mode at the specific frequency.
