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: Disclosed is a structure for detecting the vibration displacement of a speaker, including: a vibration system having a movable pole plate; a magnetic circuit system; and a fixed pole plate provided under the vibration system and opposite to the movable pole plate, the movable pole plate and the fixed pole plate constituting a capacitor. Also disclosed is an acoustoelectric inter-conversion dual-effect device, further including an impedance transformer connected to the capacitor and including a field effect transistor and a diode. In the present invention, a movable pole plate of a capacitor is provided on a vibration system and a fixed pole plate is provided under the vibration system and fixed in position. When the vibration system vibrates, the change in capacitance is detected to calculate the actual displacement of the vibration system, which can reduce the power of the speaker device when the actual displacement of the vibration system exceeds a safety threshold. For an electronic device adopting such a speaker structure, the displacement of the vibration system of a speaker product can be detected in real time at the system end of the electronic device.
