Embodiment 1

[0024] like Figure 6-Figure 9 As shown, a loudspeaker includes an upper cover 10, a lower cover 20 and a sounding unit, the upper cover 10 and the lower cover 20 are fixedly connected to form an accommodating cavity, and the sounding unit is installed in the accommodating cavity Inside, the loudspeaker also includes a protruding structure 40 mounted on the upper cover 10, the protruding structure 40 includes opposite first side walls 401 and second side walls 402, and the sounding unit includes a basin frame 302, The vibration system and the magnetic circuit system housed in the basin frame 302, the magnetic circuit system is used to drive the vibration system, the vibration system includes a speaker fixed on the side of the basin frame 302 close to the upper cover 10 The membrane 3011 and the voice coil that drives the sound membrane 3011 to vibrate and produce sound. The lower surface of the sound membrane 3011 is attached to the upper surface of the basin frame 302, and t...

Embodiment 2

[0030] The difference between this embodiment and Embodiment 1 is that: the bottom of the inner opening of the sound outlet channel 102 is connected to the bottom of the second side wall (402) through an inclined plate surface, and the outlet The bottom of the inner opening of the sound channel 102 is lower than the bottom of the second side wall (402). This arrangement can well prevent water from stagnating between the sound outlet channel 102 and the second side wall 4 .

Abstract

The invention provides a loudspeaker, which includes an upper cover, a lower cover and a sounding unit, the upper cover and the lower cover are fixedly connected to form a receiving cavity, the sounding unit is installed in the receiving cavity, and the loudspeaker also includes a A raised structure, the raised structure includes opposite first side walls and second side walls, the sounding unit includes a sound diaphragm and a basin frame, the lower surface of the sound diaphragm is attached to the upper surface of the basin frame, and the sound diaphragm The side of the basin, the side of the pot frame and the first side wall of the raised structure form a glue groove; the upper cover is provided with a sound outlet and a sound channel, and the outer end opening of the sound channel communicates with the sound outlet The bottom of the inner opening of the sound outlet channel is connected to the bottom of the second side wall, and the second side wall partially blocks the inner end opening of the sound outlet channel. The setting of the protruding structure in the present invention can not only play a waterproof role, but also its height is lower than that of the support beam, which basically does not affect the emission of sound.

Description

【Technical field】 [0001] The invention relates to the technical field of electroacoustic conversion, in particular to a loudspeaker. 【Background technique】 [0002] With the advent of the mobile Internet era, the number of smart mobile devices continues to increase, and speakers for playing sound are also widely used in current smart mobile devices. [0003] like Figure 1-Figure 5 As shown, it is an existing loudspeaker, which includes an upper cover 1, a lower cover 2 which is combined with the upper cover 1 to form a storage space, and a sound-emitting unit housed in the storage space. A support beam 11 is provided at the position of the sound hole 5, and glue is applied on the support beam 11 to be glued to the monomer, so that the gap between the sound membrane 3 and the basin frame 4 will not enter the gap so as to realize waterproofing. However, the supporting beam has a certain height, and the presence of the supporting beam will greatly hinder the sound channel 6 ,...
