Abstract: The present disclosure discloses a sounding device including a frame, a vibration system mounted on the frame, including a diaphragm fixed to the frame and enclosing a front cavity with the frame; and a magnet system configured to drive the vibration system to generate sound, enclosing a rear cavity with the diaphragm and the frame; a connection hole is provided on the frame for connecting the front cavity with the rear cavity; an air-permeable membrane is inserted into the frame and covers the connection hole. The sounding device in the present disclosure has high assembly performance, waterproof performance and acoustic performance.

Abstract: A method for manufacturing a heat conductive adhesive film includes: forming a non-solid heat conductive adhesive layer with cured particles on a substrate; forming several bumps on the non-solid heat conductive adhesive layer while performing curing, so as to yield the heat conductive adhesive film with several bumps. A heat conductive adhesive film and an OLED panel are provided. Several bumps are formed on a flat surface of the heat conductive adhesive film, thus increasing the surface area of the heat conductive adhesive film such that heat from the heat generating unit can be duly discharged.
