摘要： A sound absorbing structure is constituted of a vibration plate and a rear air layer and is installed in a luggage compartment or trunk which is separated from a cabin in a vehicle. Sound waves entering into the luggage compartment drive the vibration plate to vibrate so that acoustic energy is converted into mechanical energy and is consumed by way of vibration of the vibration plate. By appropriately setting parameters and dimensions, the sound absorbing structure efficiently absorbs low-frequency sound such as road noise occurring due to friction of wheels of the vehicle traveling on a road.

摘要： A sound absorbing structure is constituted of a housing having a hollow portion and an opening and a vibration member composed of a board or diaphragm. The vibration member is a square-shaped material having elasticity composed of a synthetic resin and is bonded to the opening of the housing, thus forming an air layer closed inside the sound absorbing structure by the housing and the vibration member. In the sound absorbing structure, when the lateral/longitudinal dimensions of the air layer and characteristics of the vibration member (e.g. a Young's modulus, thickness, and Poisson's ratio) are set such that the fundamental frequency of a vibration occurring in a bending system falls within 5% and 65% of the resonance frequency of a spring-mass system, a vibration mode having a large amplitude occurs in a frequency band lower than the resonance frequency of the spring-mass system, this improving the sound absorption coefficient.

摘要： A sound absorbing structure is constituted of a housing and a vibration member. The vibration member composed of a synthetic resin having elasticity is constituted of a first member and a second member whose surface density is smaller than the surface density of the first member, wherein the first member is fixed into a center hole of the second member so as to form a single board of the vibration member. Since the surface density of the center portion of the vibration member is higher than the surface density of the peripheral portion of the vibration member, the frequency of absorbed sound further decreases in comparison with the foregoing structure in which the vibration member is increased in weight to change the frequency of absorbed sound. This makes it possible to arbitrarily change the frequency of absorbed sound without substantially changing the overall weight of the sound absorbing structure.

摘要： An acoustic resonance device is installed in a compartment of a vehicle so as to reduce a low-frequency sound pressure (or noise) dependent upon a natural vibration. Specifically, an acoustic resonance device is a panel/diaphragm resonator, a resonance pipe, or a Helmholtz resonator, the inner space of which communicates with the compartment via an opening. The acoustic resonance device is positioned in proximity to an antinode of sound pressure owing to a natural vibration occurring in a driver/passenger space inside the compartment. Alternatively, the acoustic resonance device increases a particle velocity at a specific natural frequency or decreases sound pressure at an excitation frequency which occurs due to an external condition of the vehicle. The acoustic resonance device can be installed in a roof, a seat, a pillar supporting the roof, or a door of a vehicle.

摘要： Speaker includes a diaphragm, and a linear vibrating device attached to a peripheral portion of the diaphragm. The linear vibrating device includes a conductor line meandering in a wave-like shape along the surface of the diaphragm, and magnets disposed in opposed relation to the conductor line. The magnets are disposed in regions surrounded by adjoining mountain portions and adjoining valley portions of the conductor line. The magnets are arranged in such a manner that every adjoining magnets have their magnetic poles of opposite polarities located close to the conductor line.

摘要： A standing wave attenuation device is installed in a cabin of a vehicle so as to reduce a standing wave caused by external noise such as road noise. The standing wave attenuation device provides a closed loop including a feedback comb filter with a feedback loop, a microphone, a speaker, and a delay element. The delay element adjusts the phase of the output signal of the feedback comb filter such that the time needed for one-time circulation of a signal through the feedback loop matches a half period of the standing wave. An original sound including the standing wave is picked up by the microphone and subjected to processing so that the speaker produces a sound wave with the inverse phase against the phase of a sound wave constituting the standing wave, so that the standing wave is canceled out by the sound wave emitted from the speaker.
