[0031] Reference to "embodiment" herein means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of this utility model. The phrase appears in various places in the description and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0032] To enable those skilled in the art to better understand the solution of this utility model, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the drawings.

[0033] As Figures 1-5 shown, it is an embodiment provided by this utility model.

[0034] The embodiment of this utility model provides a loudspeaker, comprising: a loudspeaker main body 10 and a microphone 20. An accommodation groove 30 is formed on the loudspeaker main body 10. The microphone 20 can be received in the accommodation groove 30. The size and shape of the accommodation groove 30 are adapted to the microphone 20 and can completely receive the microphone 20 in the accommodation groove 30. Preferably, the outer side wall of the microphone 20 is just flush with the outer end face of the accommodation groove 30.

[0035] A magnetic attraction plate 31 and a slope 32 are provided at the bottom of the accommodation groove 30. The magnetic attraction plate 31 is located near the middle of the bottom of the accommodation groove 30. The upper end of the slope 32 is connected to the lower side edge of the magnetic attraction plate 31. The lower end of the slope 32 extends downward to the lower end of the accommodation groove 30. The vertical distance from any point on the slope 32 to the outer end face of the accommodation groove 30 is not less than the vertical distance between the magnetic attraction plate 31 and the outer end face of the accommodation groove 30, and the vertical distance from the upper end to the lower end of the slope 32 to the outer end face of the accommodation groove 30 gradually increases. A magnetic attraction block 21 is provided on the inner side wall of the microphone 20. The upper half of the magnetic attraction block 21 can be magnetically connected to the magnetic attraction plate 31, and the microphone 20 can be fixed in the accommodation groove 30 to prevent it from falling off during storage.

[0036] Specifically, in the storage state of the microphone 20, that is, when the microphone 20 is stored in the receiving groove 30, the upper half of the bottom surface of the magnetic attraction block 21 is parallelly attached to the magnetic attraction plate 31. Since the plane where the magnetic attraction plate 31 is located is not lower than the slope 32, the lower half of the magnetic attraction block 21 will be suspended above the slope 32. At this time, the outer sidewall of the microphone 20 is parallel to the magnetic attraction plate 31 and does not extend beyond the outer end of the receiving groove 30, that is, the outer sidewall of the microphone 20 is flush with the outer end surface of the receiving groove 30, or the outer sidewall of the microphone 20 is lower than the outer end surface of the receiving groove 30. In the removable state of the microphone 20, that is, when the user wants to remove the microphone 20 from the receiving groove 30, the lower end of the microphone 20 can be pressed down with an appropriate force, so that the lower half of the magnetic attraction block 21 is parallelly attached to the slope 32, and the upper half of the magnetic attraction block 21 naturally tilts upward and is suspended above the magnetic attraction plate 31. At this time, the upper end of the microphone 20 protrudes beyond the outer end of the receiving groove 30, and the adsorption force between the magnetic attraction block 21 and the magnetic attraction plate 31 is also smaller, which is convenient for the user to pinch with two fingers or pick with one finger.

[0037] After adopting the above loudspeaker, the receiving groove 30 is arranged on the loudspeaker main body 10 to store the microphone 20, so that the microphone 20 can be completely stored in the receiving groove 30 in the storage state and will not be exposed outside the receiving groove 30 and is easily damaged by collision or extrusion. The magnetic attraction plate 31 arranged at the bottom of the receiving groove 30 is magnetically connected with the magnetic attraction block 21 arranged on the microphone 20 for fixation to prevent falling off. Then, the arranged slope 32 provides a space for pressing down the lower end of the microphone 20. When the user wants to remove the microphone 20 from the receiving groove 30, only the lower end of the microphone 20 needs to be gently pressed down, and its upper end can be tilted up and exposed outside the receiving groove 30 for taking. Both storage and removal are very convenient.

[0038] Furthermore, the vertical distance from the end of the slope 32 far from the magnetic attraction plate 31, that is, the lower end of the slope 32, to the upper surface of the magnetic attraction plate 31 is greater than or equal to half of the thickness of the microphone 20, so that when the lower end of the microphone 20 is completely pressed down towards the slope 32, at least half of the upper end of the microphone 20 can be exposed from the outer end of the receiving groove 30, providing a sufficient contact area for the user to take the microphone 20 and making it easier for the user to take the microphone 20.

[0039] Specifically, a step 33 higher than the magnetic attraction plate 31 is provided at the bottom of the receiving groove 30. The step 33, the magnetic attraction plate 31 and the slope 32 are connected in sequence. The sizes of their orthographic projections on the bottom of the receiving groove 30 are the same as those of the microphone 20 on the bottom of the receiving groove 30. The height of the step 33 is equal to the thickness of the magnetic attraction block 21. The step 33 is located at one end of the magnetic attraction plate 31 away from the slope 32. The step 33 can abut against the inner side wall of the microphone 20. When the microphone 20 is received in the receiving groove 30, the step 33 can support the upper part of the inner side wall of the microphone 20, so that the lower end of the microphone 20 will not tilt up, making the connection between the microphone 20 and the receiving groove 30 more stable.

[0040] Specifically, connection contacts 22 are provided on the inner side wall of the microphone 20. The connection contacts 22 are used to connect to the internal charging circuit of the microphone 20. Elastic ejector pins 34 are provided on the step 33. The elastic ejector pins 34 are used to connect to the internal circuit of the speaker host 10. The elastic ejector pins 34 can elastically abut against and be electrically connected to the connection contacts 22, so that the internal power supply of the speaker host 10 can charge the microphone 20, facilitating the improvement of the battery life of the microphone 20.

[0041] Further, the magnetic attraction block 21 is in the shape of a round cake, and the magnetic attraction plate 31 is in the shape of a semi-circle. The area of the magnetic attraction plate 31 is equal to half of the bottom area of the magnetic attraction block 21, which can not only ensure the adsorption force between the magnetic attraction block 21 and the magnetic attraction plate 31, but also make it more labor-saving when the magnetic attraction block 21 tilts up and is suspended from the magnetic attraction plate 31.

[0042] Further, two microphones 20 and two receiving grooves 30 are provided. The two microphones 20 can be respectively received in the corresponding receiving grooves 30. Users can choose to use the two microphones 20 simultaneously or use any one of them alone according to different usage scenarios. For example, the two microphones 20 can be used alternately. When using one microphone 20, the other microphone 20 can be charged. When the power of one microphone 20 is exhausted, the other fully charged microphone 20 can be replaced for use. Rotating like this can ensure the battery life of the microphone 20 and eliminate the power anxiety of the microphone 20.

[0043] Further, a back clip 11 is provided on the back of the speaker host 10. The back clip 11 is located between the two receiving grooves 30. The back clip 11 can be used to hang or clip on the user's waist, such as on a belt or the edge of a pocket, facilitating hands-free use.

[0044] Further, two rope buckles 12 are provided on the speaker host 10. The rope buckles 12 are used to connect a hanging rope. When there is no suitable position on the user's body to hang or clip the back clip 11, the user can also choose to hang the speaker host 10 on the body with the hanging rope for use.

[0045] Of course, the amplifier main unit 10 is also provided with components such as a volume adjustment knob, function buttons, a charging interface, etc., and the microphone 20 is also provided with a switch button, a charging indicator light, etc., which will not be further elaborated herein.
