Embodiment Construction

[0020] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0021] refer to Figure 1 to Figure 5 As shown, in this embodiment, a sounding device 100 provided by the present invention includes: a housing 1 with a housing space and a sounding unit 101 housed in the housing. The sounding unit 101 includes a vibrating membrane 21 Vibration system 20 and magnetic circuit system 30.

[0022] The casing 1 includes an upper casing 11 and a lower casing 12 , and the upper casing 11 and the lower casing 12 are assembled with each other to form a receiving space.

[0023] The lower casing 12 includes a substantially flat metal bottom wall 121 , a plurality of lower metal sidewalls 122 bent and extending from the edge of the metal bottom wall 121 toward the upper casing 11 and arranged at intervals, and connecting two adjacent lower casings. A plurality of sealing connections 123 of the metal sidewall 122 . The sealing ...

Abstract

The invention provides a sounding device, which includes: a casing with a storage space and a sounding unit accommodated in the storage space, the sounding unit includes a magnetic circuit system and a vibration system with a diaphragm; the casing includes an upper casing And the lower casing; the lower casing includes a metal bottom wall, a plurality of lower metal side walls formed by bending and extending from the metal bottom wall and arranged at intervals, and a sealing connection piece arranged between two adjacent lower metal side walls; the lower metal One end of the side wall close to the upper housing is bent and extended perpendicular to the vibration direction of the diaphragm to form a bent edge, and the bent edge and the bottom surface of the sealing connector together form a sealing surface, and the sealing surface is connected with the upper housing to form a seal. The above-mentioned sound-generating device bends the metal side wall end of the lower case to form a bent edge to connect with the upper case, and at the same time only sets plastic parts at the four corners to form a seal between the upper case and the lower case by inward folding Surface, and the plastic part reduces the volume, which in turn increases the volume of the powder filling space.

Description

【Technical field】 [0001] The invention relates to the technical field of sound generating devices, in particular to a sound generating device. 【Background technique】 [0002] The current sounding device includes a casing with a receiving space and a sounding unit accommodated in the casing. The casing includes an upper casing and a lower casing that are assembled with each other to form the receiving space. The lower casing usually includes a plastic frame and a metal casing covered on the plastic frame. The sounding unit divides the storage space into a front cavity and a rear cavity, and the lower shell, the sounding unit and part of the upper shell together form the rear cavity. Therefore, the space occupied by the plastic frame reduces the volume of the rear cavity, and the space for powder filling becomes smaller, thereby affecting the acoustic performance. [0003] Therefore, it is necessary to provide a new sound emitting device to overcome the above-mentioned defe...
