Sound-absorbing particle, preparation method thereof, and speaker

Abstract

The present disclosure relates to a sound-absorbing particle, a preparation method thereof, and a speaker. The sound-absorbing particle is formed by combing a molecular sieve and an adhesive, and includes a first flat surface and a second flat surface symmetrically distributed to each other, and a arc-shaped side edge connecting the first flat surface and the second flat surface. A ratio of the molecular sieve and the adhesive by weight is 1:(0.02-0.1). The sound-absorbing particle according to the present disclosure has a smaller longitudinal size under the same volume, the path of gas entering the interior of the sound-absorbing particle is shorter, and more gas molecules can be adsorbed or desorbed in a short time, thus making the sound-absorbing particle has better sound-absorbing effect, and filling the rear cavity of the speaker with the sound-absorbing particles can significantly improve the acoustic performance of the speaker.
