[0035] Please see Figures 1 to 5The utility model embodiment provides a kind of intelligent equipment of detachable battery, and the sound box mainly includes sound box main body 1, battery 2 and limiting component 3, wherein, sound box main body 1 is provided with battery compartment 11, battery 2 is contained in battery compartment 11 and is detachably connected relative to sound box main body 1, when battery 2 is inserted into battery compartment 11, battery 2 has the energized position of electrical connection with sound box main body 1, the position of battery 2 in energized position is limited by limiting component 3, limiting component 3 is arranged at the side of the mouth of battery compartment 11, so that user sees battery compartment 11 more easily find limiting component 3 simultaneously.Specifically, the battery 2 of the present scheme is set to be detachably connected relative to sound box main body 1, so that when the capacity of battery 2 attenuates, user can restore normal use time by replacing battery 2, to increase the service life of sound box as a whole, the present scheme can also be equipped with multiple batteries 2, when the battery 2 in sound box is exhausted, battery 2 in sound box can be taken out, and another battery 2 full of power is loaded to continue using sound box, to prolong the use time of sound box in outdoor scene etc..In addition, the present scheme also limits battery 2 in energized position by limiting component 3, to prevent the phenomenon that battery 2 falls off outward when sound box is transported outdoors, and improve the reliability of battery 2 and sound box main body 1 to keep electrical connection.

[0036] Please refer to Figure 6 Limiting component 3 specifically includes sliding piece 31 and elastic piece 32, one end of elastic piece 32 is fixed relative to sound box main body 1, the other end of elastic piece 32 applies elastic force to sliding piece 31, and sliding piece 31 is used to limit the position of battery 2 in energized position under the elastic force of elastic piece 32.Preferably, the side of battery 2 is provided with limiting slot 21, when battery 2 is in energized position, sliding piece 31 is inserted into limiting slot 21 due to the elastic force of elastic piece 32, to limit the position of battery 2 and prevent battery 2 from separating from battery compartment 11 outward.When battery 2 needs to be detached, user only needs to dial sliding piece 31, so that sliding piece 31 is separated from limiting slot 21, battery 2 can be taken out and replaced.

[0037] In other embodiments, limiting component 3 can also be spring set on sound box main body 1, and the position of battery 2 can also be limited by spring abutting on battery 2.In addition, limiting component 3 can be arranged on the left and right sides of battery compartment 11, or the upper and lower sides of battery compartment 11.When limiting component 3 is arranged on the upper / lower side of battery compartment 11, limiting slot 21 can be arranged as through slot, so that sliding piece 31 can penetrate battery 2, to enhance the fixing effect on battery 2.

[0038] Please refer to again Figure 6In the embodiment, the limiting assembly 3 further comprises a fixing member 33 and a sliding base 34, both of which are fixed on the loudspeaker body 1, one end of the elastic member 32 is limited on the fixing member 33, the other end of the elastic member 32 is limited on the sliding member 31, and the sliding member 31 and the sliding base 34 are linearly slidably connected. Preferably, the sliding member 31 is provided with a sliding groove 311, and the sliding base 34 is provided with a guide rail 341 which is inserted and matched with the sliding groove 311, so as to realize the sliding connection between the sliding base 34 and the sliding member 31, and improve the linear precision of the sliding of the sliding member 31. The sliding connection between the sliding member 31 and the sliding base 34 can also be a connecting guide rod. Specifically, by designing the limiting assembly 3 in this way, the entire limiting assembly 3 can be pre-assembled externally, and then only the sliding base 34 and the fixing member 33 need to be fixed on the loudspeaker body 1, so as to quickly realize the elastic sliding function of the sliding member 31, and the limiting assembly 3 has the advantage of convenient assembly and disassembly.

[0039] Please refer again to Figure 6 Preferably, the end of the sliding member 31 facing the fixing member 33 is provided with a limiting column 312, the fixing member 33 is provided with a positioning hole 331, one end of the elastic member 32 is inserted and limited in the positioning hole 331, and the other end of the elastic member 32 is sleeved on the limiting column 312, so as to limit both ends of the elastic member 32, and ensure that the elastic member 32 will not be separated from the fixing member 33 or the sliding member 31 during the elastic deformation.

[0040] Please refer to Figures 4 to 6, the battery compartment 11 is provided with a soft shell 12, and the soft shell 12 is provided with a slot 121 for inserting the battery 2. The soft shell 12 can play a role in shock absorption, ensure the stability of the battery 2 in the battery compartment 11, and improve the reliability of the electrical connection between the battery 2 and the sound box body 1. In addition, the side wall of the slot 121 is provided with a support strip 122 for abutting with the outer wall of the battery 2. By arranging the support strip 122, the contact area between the battery 2 and the soft shell 12 when the battery 2 is inserted into the slot 121 can be reduced, thereby reducing the friction that needs to be overcome during the process of inserting the battery 2 into the slot 121. The user can insert the battery 2 into the slot 121 with less force, reduce the difficulty of inserting the battery 2 into the slot 121, and ensure that the battery 2 can be inserted into place and electrically connected with the sound box body 1. More specifically, the support strip 122 is provided with a guide slope 1221 at one end of the slot opening of the slot 121. When the battery 2 is just inserted into the slot 121, it can gradually penetrate into the slot 121 through the guide slope 1221, thereby further reducing the difficulty of inserting the battery 2, and further improving the user's experience. Optionally, the battery 2 is provided with a handle 22 away from the battery compartment 11, which facilitates the user to take out the battery 2 and reduces the difficulty of the user to disassemble the battery 2. In one embodiment, the inside of the battery compartment 11 can be provided with an elastic member (not shown in the figure). When the battery 2 is inserted into the battery compartment 11, the elastic member will be compressed by the battery 2. When the battery 2 is inserted into place, the limiting component 3 will be inserted into the limiting groove 21 of the battery 2 due to its elasticity, thereby achieving automatic locking of the battery 2. When the user overcomes the elasticity of the limiting component 3 to unlock the battery 2, the elastic member in the battery compartment 11 will automatically pop out the battery 2. At this time, the user can easily take out the battery 2 outward without the handle 22. That is, by arranging the elastic member, the battery 2 can be easily taken out without the handle 22. In actual design, the elastic member and the handle 22 can be designed alternatively, or both can be designed. When both the elastic member and the handle 22 are designed, it is more convenient for the user to take out the battery 2 outward, greatly reducing the difficulty of the user to take out the battery 2, and improving the user's experience.

[0041] Please see Figures 1 to 3The interface module 4, the battery compartment 11 and the limiting assembly 3 are arranged on the same side of the sound box body 1, so that the user can easily find the position of the battery 2. Preferably, the sound box further comprises a cover plate 5 which is detachably connected with the sound box body 1. The cover plate 5 and the sound box body 1 can be connected by fasteners or magnetic attraction. When the cover plate 5 is connected with the sound box body 1, the cover plate 5 covers the interface module 4, the battery 2 and the limiting assembly 3 at the same time. Thus, only one cover plate 5 can simultaneously play a dustproof role on the interface module 4, the battery 2 and the limiting assembly 3, thereby simplifying the structure of the sound box based on the dustproof requirement and making the structure of the sound box more compact and reasonable.

[0042] In some embodiments, the sound box can further comprise a microphone 6 which is communicatively connected with the sound box body 1 by wire or wirelessly to meet the use requirement of the user who can sing. Based on the structural design of the microphone 6, the sound box body 1 is provided with a storage structure 7 for storing the microphone 6. The storage structure 7 can be a cavity for accommodating the microphone 6. The microphone 6 is inserted into the cavity. The depth of the cavity is greater than or equal to the length of the microphone 6. The cavity comprises an opening. Through the opening, the microphone 6 is vertically or horizontally inserted into the cavity to be stored. The microphone 6 fixing structure can be arranged inside or outside the opening to fix the microphone 6 after being stored. The opening can be arranged at any position of the sound box body 1, including the top surface, the side surface or the bottom surface of the sound box body 1. The storage structure 7 can also be a groove. The microphone 6 is embedded into the groove. The microphone 6 is placed into the groove. The microphone fixing structure can be arranged inside or outside the groove to fix the microphone 6 after being stored. The microphone 6 is vertically or horizontally placed into the groove to be stored. The groove can be arranged at any position of the sound box body 1, including the top surface, the side surface or the bottom surface of the sound box body 1.

[0043] In some embodiments, the sound box body 1 can be connected with the screen 8 through a movable structure. The sound box body 1 can be provided with a screen storage slot. After the screen 8 is closed, the screen 8 is stored in the screen storage slot. The storage structure can be arranged below the screen 8. After the screen 8 is closed, the microphone 6 is completely covered by the screen 8 and is completely stored in the sound box body 1.

[0044] In some embodiments, the way to automatically turn off the microphone 6 is that the inductive element senses the distance between the sound box body 1 and the microphone 6, and when the distance between the sound box body 1 and the microphone 6 is less than or equal to a preset distance, the microphone 6 is automatically turned off. The sensing element can be one or more, and the sensing element can be a Hall element, a distance sensor, an infrared sensor, and any other single electronic element that can sense the distance between the sound box and the microphone, as well as any combination of electronic elements. The sensing element can be arranged on the sound box body 1 and / or the microphone 6. Specifically, when the microphone 6 is inserted into the cavity, the inductive element can be arranged at the opening of the cavity so that the microphone 6 is turned off just after being inserted for the first time. It can also be arranged at the end of the cavity away from the opening, which prevents the inductive element from being exposed to the outside due to the opening facing outward, causing the element to age. When the microphone 6 is fitted into the groove, the inductive element can be arranged at one end, the middle, or both ends of the groove.

[0045] If the microphone 6 is too close to the sound box body 1 while maintaining communication with the sound box body 1, it will cause howling. The sound box body 1 emits a piercing howling sound that greatly affects the user experience, especially when the sound box body 1 stores the microphone 6. The probability of howling caused by the impact and friction sound during the storage process of the microphone 6 is higher. Therefore, the microphone 6 can be automatically turned off to prevent howling during the process of the microphone 6 approaching the sound box body 1 or the sound box body 1 storing the microphone 6.

[0046] In some specific embodiments, the inductive element is a Hall element, and the sound box storage structure and the microphone 6 each have a corresponding position. The microphone 6 has a magnetic element arranged at the corresponding position, and the sound box body 1 has a Hall element arranged at the corresponding position. Alternatively, the microphone 6 has a Hall element arranged at the corresponding position, and the sound box body 1 has a magnetic element arranged at the corresponding position. The triggering condition of the Hall element can be that the detected magnetic field strength reaches a preset value. When the detected magnetic field strength is greater than or equal to the preset value, it means that the distance between the sound box body 1 and the microphone 6 meets the howling condition, and the microphone 6 needs to be turned off. Preferably, the microphone 6 has a magnetic element arranged at the corresponding position, and the sound box body 1 has a Hall element arranged at the corresponding position. Since the microphone is moved randomly during karaoke, it may be moved to other places with a relatively large magnetic field strength. Arranging a Hall element on the microphone 6 may cause the microphone 6 to be turned off incorrectly, thereby affecting the experience. The microphone 6 can be inserted for storage, and the Hall element is arranged at the opening or the end of the opening of the cavity of the sound box body 1. The microphone 6 can be put in for storage, and the Hall element is arranged at one end, the middle, or both ends of the groove.

[0047] In some embodiments, the sensing element is a Hall element, the sound box body 1 is provided with a charging structure corresponding thereto, the microphone 6 is provided with a power receiving structure corresponding thereto, and the triggering condition of the Hall element can be the magnetic field change caused by the power-on moment when the microphone 6 is charged. When the magnetic field change is detected, it means that the distance between the sound box body 1 and the microphone 6 meets the condition of triggering howling, and the microphone 6 needs to be turned off. The charging structure can be arranged on the surface of the sound box body 1, or can be arranged corresponding to the receiving structure. The microphone 6 can be inserted into the receiving structure, the charging structure is arranged at one end of the cavity of the sound box body 1 away from the opening, the power receiving structure is arranged on the bottom or the bottom surface of the microphone 6, and the Hall element is arranged near the charging structure. The Hall element can perceive the magnetic field change caused by the power-on moment; the microphone 6 can be placed into the receiving structure, the charging structure is arranged at one end, the middle or both ends of the groove of the sound box body 1, the power receiving structure is arranged corresponding to the microphone 6, and the Hall element is arranged near the charging structure. The Hall element can perceive the magnetic field change caused by the power-on moment.

[0048] In some embodiments, the sensing element is a Hall element, the sound box body 1 is provided with a charging structure, and the receiving structure and the microphone 6 are respectively provided with magnetic members. The magnetic members fix the microphone 6, and the magnetic members are arranged outside the sensing triggering range of the Hall element. The microphone 6 can be placed into the receiving structure, the charging structure is arranged at one end, the middle or both ends of the groove of the sound box body 1, the power receiving structure is arranged corresponding to the microphone 6, and the Hall element is arranged near the charging structure. The Hall element can perceive the magnetic field change caused by the power-on moment. Preferably, the charging structure is arranged at one end of the groove of the sound box body 1, and the magnetic members are arranged at the other end or the middle of the groove of the sound box body 1. When the microphone 6 is cylindrical, the microphone 6 is provided with a button on the surface, the magnetic members are arranged on the other side opposite to the button, and the button of the microphone 6 faces the outside of the groove.

[0049] The above is only a preferred embodiment of the present application, and only the technical principle of the present application is specifically described. These descriptions are only for explaining the principle of the present application, and cannot be interpreted as limiting the protection scope of the present application in any way.
