A loudspeaker device having housing and an acoustic transducer is disclosed. The housing has a transducer space for the acoustic transducer, and a back volume space. The back volume filled with a sound adsorber material and a foam material. The sound adsorber material in the back volume space is configured to virtually increase the size of the back volume space, and shift the resonant frequency of the back volume space. The foam material separates the sound adsorber from the transducer space and facilitates gas exchange and air flow within the back volume space and between the sound adsorber and the transducer space. The foam material is configured in different arrangements to facilitate the gas exchange and air flow.

Loudspeaker device having foam insert to improve gas distribution in sound adsorber material

An acoustic device having a housing and an acoustic transducer is disclosed. The housing has a transducer space for the acoustic transducer, and a back volume space. The back volume is filled with a sound adsorber material. The sound adsorber material in the back volume space is configured to virtually increase the size of the back volume space, and shift the resonant frequency of the back volume space. The acoustic chamber for the acoustic transducer and the sound adsorber material is integral to the split-shell housing of the acoustic device. The sound adsorber material is retained in a portion of the acoustic chamber by an acoustically permeable material that facilitates gas exchange within the back volume space, and between the sound adsorber material and the transducer space. The acoustically permeable material is configured in different arrangements to facilitate the gas exchange.

Integrated loudspeaker device having an acoustic chamber containing sound adsorber material

An audio system that comprises an electro-acoustic transducer mounted onto a housing that forms a resonance volume which is at least partially filled with sound absorbing material, wherein the housing is realized with a deep-drawn foil at least partially filled with grains of the sound absorbing material.
