[0025] In order to make the purpose, technical scheme and advantages of the utility model more clear, the following will combine the specific embodiment of the application, and refer to the drawings, and the technical scheme of the utility model is clearly and completely described.

[0026] As Figures 1-4 and Figure 8 shown, a loudspeaker structure improved in heat dissipation, comprising: a mobile phone shell 1, the inside of the mobile phone shell 1 is provided with a loudspeaker unit 2, the loudspeaker unit 2 is matched with an earpiece 3;

[0027] The earpiece 3 includes: a shell connecting part 301, the shell connecting part 301 is provided with a loudspeaker connecting part 302, the adjacent side wall of the shell connecting part 301 and the loudspeaker connecting part 302 is provided with an air inlet hole 303, the inside of the shell connecting part 301 is provided with a shunt air duct 304, the shunt air duct 304 penetrates the shell connecting part 301 and is communicated with the air inlet hole 303.

[0028] By setting the air inlet hole 303 and the shunt air duct 304 on the shell connecting part 301 of the earpiece 3, the effective heat dissipation of the loudspeaker unit 2 is realized, and the hot air flow generated when the loudspeaker unit 2 sounds can be effectively avoided to be directly transmitted to the user's ear through the front cavity sound hole 101, which affects the user's use experience; the setting of the shunt air duct 304 can realize the effective heat dissipation effect without significantly increasing the design complexity or occupying additional space, which is particularly important for compact devices such as mobile phones;

[0029] As Figure 5 , Figure 7 , Figure 9As shown, the air inlet hole 303 of the earpiece in the traditional speaker structure penetrates the shell connecting part 301, when the speaker unit 2 emits sound, the air flow generated by vibration is directly transmitted to the front cavity sound outlet hole 101 through the air inlet hole 303, so that the user's ear can feel the hot air flow generated when the speaker unit 2 emits sound, affecting the user's experience.

[0030] As shown in Figure 4 and Figure 8 , the shell connecting part 301 is L-shaped, including a horizontal side wall and a vertical side wall, the horizontal side wall cooperates with the speaker connecting part 302, the air inlet hole 303 is opened on the horizontal side wall, and the shunt air duct 304 is opened below the horizontal side wall and arranged along the length direction of the shell connecting part 301.

[0031] As shown in Figure 4 and Figure 8 , a plurality of shunt micro-holes 305 are opened on the vertical side wall, the shunt micro-holes 305 communicate with the shunt air duct 304 and are arranged along the width direction of the shell connecting part 301.

[0032] The L-shaped design makes the shell connecting part 301 have a horizontal side wall and a vertical side wall, such structure not only facilitates the cooperation with the speaker connecting part 302, but also effectively arranges the air inlet hole 303 and the shunt air duct 304 in limited space; the air duct directions of the air inlet hole 303, the shunt air duct 304 and the shunt micro-hole 305 are perpendicular to each other inside the mobile phone shell 1, so that when the speaker unit 2 emits sound, the air flow can flow uniformly in all directions inside the mobile phone shell, avoiding that the air flow has only one inlet and outlet channel when the speaker unit emits sound, so that the user's ear is affected by the air flow.
