▎ 摘　　要

NOVELTY - The ball top comprises a heat conduction layer (110) comprising an organic aerogel material and a heat conduction filler (114). The organic aerogel material is oriented in a direction perpendicular to the surface of the ball top. The heat conduction filler is added into the organic aerogel material and is arranged along the orientation direction of the organic aerogel material. USE - Ball top for sounding device of vibrating diaphragm assembly used in electronic device (all claimed). Uses included but are not limited to mobile phone, notebook computer, tablet computer, virtual reality (VR) device, augmented reality (AR) device, true wireless Bluetooth (TWS) headset, smart speaker. ADVANTAGE - The ball top is made of organic gas to gel its own quality. The heat conducting filler is arranged along the orientation direction of the organic gas material gel to transfer the heat to the heat conducting layer outer side of the radiating layer, and thus improving radiating efficiency of the ball top. DETAILED DESCRIPTION - AN INDEPENDENT CLAIM is included for a vibrating diaphragm assembly. DESCRIPTION OF DRAWING(S) - The drawing shows a structural schematic diagram of the heat conducting layer of the ball top of sounding device. 110Heat conducting layer 114Heat conducting filler
