Abstract

The invention discloses a dome, a loudspeaker unit and a sounding device, wherein the dome is installed on the diaphragm of the loudspeaker, the dome includes a sapphire layer and a base material layer, and the sapphire layer and the base material layer are stacked on each other It is provided that one of the sapphire layer and the substrate layer is used to combine with one side of the diaphragm, and the sapphire layer is opened with at least one through hole. The dome of the invention can improve the acoustic performance and quality of the loudspeaker.

Description

Technical field [0001] The present invention relates to the field of acoustic technology, in particular to a dome, a loudspeaker unit and a sounding apparatus. Background [0002] With the advent of the 5G mobile phone era, higher requirements have been put forward for the material performance of mobile terminals, such as mobile phones. Due to the high frequency of 5G mobile phones, its terminal antenna is very sensitive to surrounding metal and carbide materials, especially metal materials are very serious to 5G signal interference. The dielectric constant of the material around the antenna of the 5G mobile phone will affect the bandwidth of the antenna, the higher the general dielectric constant, the stronger the binding on the electromagnetic field, and the corresponding narrowing of the bandwidth, so the lower the dielectric constant of the medium around the antenna, the better. [0003] In the traditional design, the dome position of the sounding device often uses metal mate...
