Abstract: A protective apparatus for sound-absorbing particles (4) in a sounding apparatus, comprising a housing (1) and a rear acoustic cavity formed inside the housing (1). The rear acoustic cavity is filled with sound-absorbing particles (4). A sound circulation channel (5) communicating the rear acoustic cavity with the outside is provided on the housing (1). A sound transmission layer (3) used for preventing the sound-absorbing particles (4) from being exposed covers an entrance of the sound circulation channel (5). The sound transmission layer (3) of the protective apparatus separates the sound circulation channel (5) from the rear acoustic cavity, such that airflow in the rear acoustic cavity passes through the sound transmission layer (3) and then flows out of the sound circulation channel (5). Configuration of the sound transmission layer (3) can hinder the sound-absorbing particles (4), prevent the sound-absorbing particles (4) from entering the sound circulation channel (5), and do not influence outflow of airflow. The problem in the prior art that sound-absorbing particles (4) are easily exposed or block a sound circulation channel (5) is solved, and the quality of a sounding apparatus is ensured.

Abstract: The present invention discloses a speaker device and electronic equipment. The speaker device comprises a speaker body, an audio signal input terminal connected with the speaker body, and a DC voltage signal input terminal connected with the speaker body. The electronic equipment comprises the speaker device and a DC voltage signal output circuit. The present invention further discloses a method for reducing a low frequency distortion degree of the speaker of the electronic equipment, and the method is realized by additionally providing a DC voltage signal to the input end of the speaker. In the present invention, a distortion degree of the speaker device at a low-frequency working condition can be reduced, and inconsistency of low frequency distortion of the speaker device, caused by mass production, can be reduced.
