Embodiment
Lift preferred embodiment below, and come by reference to the accompanying drawings clearlyer intactly the present invention to be described.
As shown in Figure 5 and Figure 6, a kind of loud speaker, it comprises loudspeaker housing 21, magnet steel 22 and vibrating diaphragm 23, magnet steel 22 is embedded at the rear end face of loudspeaker housing 21, vibrating diaphragm 23 is embedded at the front end face of loudspeaker housing 21, and magnet steel 22 is connected with metal clips 24, and metal clips 24 extends to the front end face of loudspeaker housing 21 from the rear end face of loudspeaker housing 21, the front end face of loudspeaker housing 21 is also provided with conducting foam 25, and conducting foam 25 and magnet steel 22 are for being electrically connected.The material of loudspeaker housing 21 can select plastic cement.
As shown in Fig. 5, Fig. 6, Fig. 7 and Fig. 8, a kind of mobile terminal, it circuit board 33 comprising mobile terminal fore shell 31, mobile terminal back cover 32 and be located between mobile terminal fore shell 31 and mobile terminal back cover 32, aforesaid loud speaker 2 is provided with between circuit board 33 and mobile terminal back cover 32, the front end face of loudspeaker housing 21 is towards circuit board 33, metal clips 24 is electrically connected with circuit board 33, and conducting foam 25 is electrically connected with circuit board 33.
Circuit board 33 is provided with through hole 331, the front end face of loudspeaker housing 21 is located in the surrounding of through hole 331 by the first seal member 34, the second seal member 35 is provided with, sound chamber before being formed between loud speaker 2, circuit board 33 and mobile terminal fore shell 31 between circuit board 33 and mobile terminal fore shell 31.
The 3rd seal member 36 is provided with, sound chamber after being formed between mobile terminal back cover 32, circuit board 33 and loud speaker 2 between circuit board 33 and mobile terminal back cover 32.
