摘要： A speaker unit is attached to an opening section formed on an front surface of a cabinet. In an inside of the cabinet, fibrous activated carbon (activated carbon fiber) is located. A pressure change in the inside of the cabinet, which changes according to a sound pressure of the speaker unit, is suppressed by physical adsorption by the activated carbon. Further, since the activated carbon fiber has micro pores, which physically adsorbs a gaseous body, situated on a surface of the fiber, a loss in acoustic energy at the time of physical adsorption is small, and thus it is possible to prevent deterioration in a sound pressure level.

摘要： A material for improving the sound pressure level at the bass reproduction limit of the present invention is composed of an activated carbon having a cumulative pore volume of 0.4 ml/g or more for the pores each having a radius of 50 angstroms or less. Preferably, this activated carbon has a cumulative pore volume of 0.1 ml/g or less for the pores each having a radius of 7 angstroms or less. In particular, when a sound pressure level improving material in which the activated carbon has a cumulative pore volume of 0.5 ml/g or more for the pores each having a radius of 18 angstroms or less is installed in a cabinet of a loudspeaker device, the material alleviates pressure fluctuations of a gas within the cabinet caused by vibration of a loudspeaker, and thus a very good bass reproduction effect is attained. Moreover, in the case where a sound pressure level improving material in which the activated carbon has a cumulative pore volume of 0.4 ml/g or more for the pores each having a radius of 18 to 50 angstroms is installed in the cabinet, a loudspeaker device having a good bass reproduction effect even in an atmosphere of high humidity is obtained.
