Description

Technical Field

[0001] The utility model relates to the technical field of audio housings, in particular to a drop-proof plastic housing for audio. Background Art

[0002] The function of speakers is to convert audio electrical energy into corresponding sound energy and transmit it to the surrounding space to transmit information in the form of sound. The outer shell of the speakers can protect the internal components, and is equipped with holes for ventilation and heat dissipation to prevent the internal components of the speakers from affecting the transmission of sound due to untimely heat dissipation.

[0003] Existing speaker shells are usually made of plastic because plastic is relatively light. However, plastic may be fragile and easily break when impacted. In addition, if the corners of the speaker are too sharp or the shell is too thin, it is more likely to be damaged when it falls. The speaker may be used in a variety of different environments, such as during transportation, outdoor activities, etc. In these environments, accidental falls or collisions may cause damage to the shell. When transporting the speaker, careless slips or collisions may cause it to fall; during outdoor activities, it may encounter uneven ground or collisions with other objects. These situations increase the risk of damage to the speaker shell. Utility Model Content

[0007] Furthermore, the inner support mechanism includes a movable block, an insertion rod and a movable sheet. The outer side of the bottom end of the insertion rod is movably inserted into the top end of the telescopic frame, the bottom end of the movable sheet is inserted into the inner side of the telescopic frame, and the outer side of the movable sheet is movably connected to the heat dissipation mechanism and the inner side of the support plate. The inner circle side walls of the heat dissipation mechanism and the support plate can slide along the outer side of the movable sheet when sliding up and down.

[0008] Furthermore, the top end of the insertion rod is inserted into the bottom end of the movable block, the two side ends of the movable sheet are movably connected between the side walls of the insertion rod, the top end of the movable sheet is movably connected to the bottom end of the movable block, and the side walls of the heat dissipation mechanism and the support plate can retract as the telescopic mechanism is stretched downward.

[0009] Furthermore, the heat dissipation mechanism includes a filter, a slider and a splicing rod, the top end of the filter is inserted into the inner side of the bottom of the sleeve, the bottom end of the splicing rod is slidably connected to the top side of the support plate, the top end of the topmost filter is movable and inserted into the inner side of the bottom end of the sleeve, the inner ring of the filter is sleeved on the bottom outer ring of the inner support mechanism, the heat dissipation mechanism and the side wall of the support plate slide up and down, and the side walls of the filter slide against each other.

[0010] Furthermore, the top end of the slider is slidably connected to the bottom side of the filter screen, the top end of the splicing rod is movably connected to the bottom end of the slider, and the filter screen and the side wall of the support plate slide up and down.

In normal state, the merging frame is retracted to its original position.

[0012] Furthermore, the bottom end of the buckle frame is fixedly connected to the outside of the stacking frame, and the top end of the merging frame is fixedly connected to the bottom end of the stacking frame.

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.

[0023] like Figure 1-Figure 3 As shown, in some embodiments, the inner support mechanism 1 includes a movable block 101, an insertion rod 102 and a movable sheet 103, the outer side of the bottom end of the insertion rod 102 is movably plugged into the top of the telescopic frame 5, the bottom end of the movable sheet 103 is plugged into the inner side of the telescopic frame 5, the outer side of the movable sheet 103 is movably connected to the heat dissipation mechanism 3 and the inner side of the support plate 4, the top end of the insertion rod 102 is plugged into the bottom end of the movable block 101, the two side ends of the movable sheet 103 are movably connected between the side walls of the insertion rod 102, and the top end of the movable sheet 103 is movably connected to the bottom end of the movable block 101;

[0024] like Figure 1 and Figure 4 As shown, in some embodiments, the heat dissipation mechanism 3 includes a filter 301, a slider 302 and a splicing rod 303, the top of the filter 301 is inserted into the inner side of the bottom of the sleeve 2, the bottom end of the splicing rod 303 is slidably connected to the top side of the support plate 4, the top of the topmost filter 301 is movable and inserted into the inner side of the bottom end of the sleeve 2, the inner ring of the filter 301 is sleeved on the outer ring of the bottom end of the inner support mechanism 1, the top of the slider 302 is slidably connected to the bottom side of the filter 301, and the top of the splicing rod 303 is movably connected to the bottom end of the slider 302;

[0025] like Figure 1 and Figure 5 As shown, in some embodiments, the telescopic mechanism 6 includes a stacking frame 601, a buckle frame 602 and a merging frame 603, the inner side of the stacking frame 601 is movably connected to the outer side of the telescopic frame 5, the top end of the buckle frame 602 is movably connected to the bottom end of the telescopic frame 5, the bottom end of the merging frame 603 is fixedly connected to the top end of the base 7, the bottom end of the buckle frame 602 is fixedly connected to the outer side of the stacking frame 601, and the top of the merging frame 603 is fixedly connected to the bottom end of the stacking frame 601.

[0026] like Figure 1 and Figure 4As shown, the sound is transmitted upward from the inner side of the telescopic frame 5 to the surroundings, and the fluctuation of the sound is accompanied by knocking and shaking, so that the gap between the side walls of the heat dissipation mechanism 3 and the support plate 4 is pushed, and the side walls of the heat dissipation mechanism 3 and the support plate 4 slide up and down, and the side walls of the filter 301 slide against each other, and the filter 301 and the side walls of the support plate 4 slide up and down, that is, the side walls of the heat dissipation mechanism 3 and the support plate 4 telescope and slide up and down, while the sound waves are transmitted, the air flow inside the telescopic frame 5 can also be driven to flow inside and outside, which not only accelerates the transmission of sound, but also allows the internal heat to be dissipated outward along with the sound waves, and the heat dissipation of the same frequency can be maintained to avoid affecting the transmission of sound;

[0027] like Figure 1-Figure 3 and Figure 5 As shown, when the bottom ends of the heat dissipation mechanism 3 and the support plate 4 slide up and down, they can push the side walls of the stacking frame 601. When the fluctuation is large, the stacking frame 601 can be pushed to extend downward to increase the floor space of the base 7, thereby increasing the stability of the entire speaker.

In the normal state, the combined frame 603 is retracted to its original position to increase the sound transmission height of the speaker. When the inner circle side walls of the heat dissipation mechanism 3 and the support plate 4 slide up and down, they can follow the outer side of the movable sheet 103. The side walls of the heat dissipation mechanism 3 and the support plate 4 can shrink inward as the telescopic mechanism 6 is stretched downward, so that the outer edges of the entire heat dissipation mechanism 3 and the support plate 4 are located in the inner circle of the sleeve 2 and the telescopic mechanism 6, thereby preventing the heat dissipation mechanism 3 and the support plate 4 from being hit.
