Document Type and Number:
WIPO Patent Application WO/2021/000144
Kind Code:
A1
Abstract:
A sounding apparatus, comprising an upper housing (10), a lower housing (20) fitted over the upper housing (10) and forming an accommodation cavity (100) together with the upper housing (10), and a sounding unit (30) accommodated in the accommodation cavity (100). The sounding unit (30) is provided with a circumferential side wall (301) and a top positioning surface (302) connected with the circumferential side wall (301) and facing towards the upper housing (10). The upper housing (10) is provided with a cavity wall (103) opposite to the sounding unit (30), and the cavity wall (103) comprises an upper housing side wall (1031) opposite to the circumferential side wall (301). A plurality of support bosses (11) are arranged along the circumference of the upper housing side wall (1031), the support bosses (11) extend in a direction from the upper housing side wall (1031) towards the sounding unit (30) and are abutted and supported on the top positioning surface (302), and an exhaust space (13) is formed between adjacent two support bosses (11). An accommodation gap (14) is formed between the circumferential side wall (301) and the upper housing side wall (1031), the exhaust space (13) is communicated with the accommodation gap (14), and the accommodation gap (14) is filled with fixing glue (50). The device is applied to solve the problem in the prior art that bubbles formed by the bracket glue and the fixing glue (50) during assembly of the sounding apparatus would influence the sealing effect.
