[0032] The structural principle of the utility model is briefly described as follows: in the speaker described in the utility model, the sleeve 11 and the cover 12 can be relatively telescopic and relatively rotated, and when the cover 12 and the sleeve 11 rotate relatively, the cover 12 and the base 4 also rotate relatively; therefore, when the speaker needs to be carried outside, the user can compress the sleeve 11 and the cover 12, at which time the elastic member 3 produces elastic deformation, and controls the cover 12 and the sleeve 11 to rotate relative to each other, so that the hook 121 can be engaged with the buckle 41, so that the speaker remains in a compressed state, and the speaker is small in size and has good portability; when the speaker needs to be used to play music, the user can control the cover 12 and the sleeve 11 to rotate relative to each other, so that the hook 121 can be disengaged from the buckle 41, at which time the elastic member 3 elastically recovers, and the cover 12 and the sleeve 11 extend under the action of the elastic member 3, at which time the volume of the sound cavity 5 of the speaker becomes larger, and the speaker has sufficient resonance space, and the speaker can obtain excellent bass effect.

[0033] From the above description, it can be seen that the beneficial effect of the utility model is that the telescopic shell 1 of the speaker described in the utility model can be telescoped. When the speaker needs to be carried out, the telescopic shell 1 can be compressed, and the buckle 41 can be controlled to engage with the hook 121, so as to fix the compressed state of the shell. At this time, the overall volume of the speaker is small and convenient to carry; when the speaker needs to be used to play audio, the buckle 41 can be controlled to separate from the hook 121, and the elastic part 3 of the telescopic shell 1 of the mobile phone is stretched as a whole, thereby increasing the volume of the sound cavity 5.

[0035] It can be seen from the above description that providing a plurality of buckles 41 and hooks 121 can not only extend the service life of the speaker, but also improve the reliability of the speaker in a fixed compressed state.

[0036] Furthermore, the telescopic housing 1 includes at least two sleeves 11, and the at least two sleeves 11 are movably sleeved in sequence.

[0037] It can be seen from the above description that, according to actual application requirements, by increasing the number of sleeves 11, the volume of the sound cavity of the speaker in the extended state can be increased, and the volume of the speaker in the compressed state can be reduced.

[0038] Furthermore, the sleeve 11 includes a first sleeve 111 and a second sleeve 112 , the base 4 is disposed at the bottom of the first sleeve 111 , the first sleeve 111 can be movably mounted on the second sleeve 112 , and the second sleeve 112 can be movably mounted on the cover body 12 .

[0039] It can be seen from the above description that the speaker can be provided with a plurality of second sleeves 112 according to actual application requirements.

[0040] Furthermore, the top of the first sleeve 111 and the top of the second sleeve 112 are both provided with a first limiting portion 13 extending toward the side close to the sound cavity 5, and the bottom of the second sleeve 112 and the bottom of the cover body 12 are both provided with a second limiting portion 14 extending toward the side away from the sound cavity 5.

[0041] It can be seen from the above description that when the speaker is in the extended state, the cover 12 and the sleeve 11 are in contact with each other through the bottom of the first limiting portion 13 and the top of the second limiting portion 14 to prevent the cover 12 and each sleeve 11 from over-extension and resulting in separation.

[0042] Furthermore, it also includes a rubber ring 15 . The second limiting portion 14 is provided with a groove 141 , and the rubber ring 15 is arranged in the groove 141 .

[0043] It can be seen from the above description that when the speaker is in the extended state, the rubber ring 15 can improve the sealing performance of the sound cavity 5, thereby further improving the bass sound effect of the speaker.

[0044] Furthermore, it also includes a first diaphragm 6 , which is arranged on the base 4 .

[0045] It can be seen from the above description that the first diaphragm 6 arranged on the base 4 can improve the sound effect of the speaker.

[0046] Furthermore, a positioning groove 42 is provided on one side of the base 4 close to the sound cavity 5 , and one end of the elastic member 3 is disposed in the positioning groove 42 .

[0047] It can be seen from the above description that the elastic member 3 is arranged in the positioning groove 42 to improve the reliability of the elastic member 3 and prevent the elastic member 3 from tilting, which may cause the extended state of the speaker to be unable to be fixed.

[0048] Furthermore, the outer diameter of the elastic member 3 decreases toward the end thereof away from the base 4 .

[0049] Furthermore, the speaker 2 includes a bracket 21, a second diaphragm 22 and a vibration component 23, the vibration component 23 is arranged on the bracket 21, the second diaphragm 22 is arranged on the top of the bracket 21, and the bracket 21 is provided with a through hole 211 that penetrates the sound cavity 5.

[0050] It can be seen from the above description that the low-frequency vibration generated by the vibration component 23 can enter the sound cavity 5 through the through hole 211 and generate resonance through the sound cavity 5, so that the speaker can obtain excellent bass sound effects.

[0051] Embodiment 1
