DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] This specific implementation is a multifunctional teaching speaker, and its structural diagram is as follows Figure 1 and Figure 2 As shown, it includes a speaker body 1, a strap 2 is installed on one side of the back of the speaker body 1, a speaker port is provided on the side of the speaker body 1 away from the strap 2, a dustproof net 3 is laid in the speaker port, a buffer sponge ring 301 is installed around the periphery of the dustproof net 3, and a protective frame 4 is elastically mounted on the side of the speaker body 1 away from the strap 2. Specifically, two ends of the protective frame 4 are inserted into the inner sides of the speaker body 1 and are connected to a first spring 5. The end of the first spring 5 away from the protective frame 4 is fixed in the speaker body 1, so that the protective frame 4 is elastically mounted on the outer side of the speaker body 1 to provide anti-collision protection.

[0026] At the same time, the protective frame 4 is located on the outside of the dustproof net 3, and a through opening 401 is set in the middle of the protective frame 4. A number of protective rods 402 are fixed in the through opening 401, so that the protective frame 4 will not affect the normal use of the sound expansion port, and when the protective frame 4 is bumped and moves toward the speaker body 1, it can also first contact with the buffer sponge ring 301 to form secondary buffer protection.

[0027] like Figure 1 , Figure 3 and Figure 4As shown, a movable plate 6 is vertically inserted into the speaker body 1, the lower end of the movable plate 6 extends out of the bottom of the speaker body 1, and a storage plate 601 is fixed thereto, and a plurality of storage holes 602 for placing writing pens are provided on the storage plate 601, wherein a through hole corresponding to the speaker port is provided in the middle of the movable plate 6.

[0028] A cleaning block 7 is fixed to the top of the movable plate 6, and a plurality of second springs 8 are installed on the upper end surface of the cleaning block 7. The second springs 8 are connected to the top of the speaker body 1, so that the movable plate 6 is elastically installed in the speaker body 1, which is convenient for resetting after the movable plate 6 is pulled down, and a cleaning brush 9 is elastically installed on the side of the cleaning block 7, and the cleaning brush 9 abuts against the inner side of the dustproof net 3, so that when the movable plate 6 is pulled down, the cleaning brush 9 can be used to elastically scrape the inner side of the dustproof net 3 for quick cleaning.

[0029] In specific implementation, a mounting groove is provided in the cleaning block 7 , a third spring 10 is fixed in the groove, the third spring 10 is elastically connected to a cleaning plate 11 , and one end of the cleaning brush 9 extends into the cleaning block 7 and is mounted on the cleaning plate 11 .
