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： 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.
