Description

Technical Field

[0001] This utility model relates to the field of tablet computer speaker technology, and in particular to a miniature speaker for tablet computers. Background Technology

[0002] Tablet computers, also known as portable computers, are small, portable personal computers that use a touchscreen as their basic input device. The touchscreen allows users to perform tasks using a stylus or digital pen instead of a traditional keyboard or mouse. Speakers, commonly known as "horns," are a very common electroacoustic transducer that can be found in any electronic or electrical device that produces sound. Miniature speakers typically consist of three parts: a magnetic circuit system, a vibration system, and a support system. When current passes through the voice coil, the magnetic field interacts with the permanent magnet, driving the diaphragm to vibrate and produce sound.

[0003] To address this, patent publication CN207968949U discloses a miniature planar diaphragm loudspeaker, comprising a diaphragm system, a magnetic circuit system, and a fixing connection system. The diaphragm system includes a planar diaphragm formed by bonding a vibrating diaphragm to a wound conductor, an upper gasket and a lower gasket for fixing and supporting the planar diaphragm. The magnetic circuit system includes a magnet positioned above the wound conductor, a bracket for fixing the magnet, an upper magnetic guide plate glued to the magnet, and a lower magnetic guide plate positioned below the diaphragm system. The fixing connection system includes a spring positioned above the wound conductor, a plastic ring for fixing the spring, a circuit board pressed above the spring, and screws and nuts for locking and fixing the entire assembly. This miniature planar diaphragm loudspeaker, while maintaining good sound quality, reduces the planar size and volume of the loudspeaker, lowering costs. It can be applied to in-ear headphones, mobile phones, tablets, and other sound-generating devices requiring miniature loudspeakers.

[0004] The aforementioned miniature planar diaphragm loudspeaker aims to reduce the planar size and volume of the loudspeaker, thereby lowering costs. It can be applied to sound-generating devices that require miniature loudspeakers, such as in-ear headphones, mobile phones, and tablets. However, during use, the loudspeaker housing is difficult to disassemble, the loudspeaker is difficult to disassemble, and if the loudspeaker malfunctions, repair is troublesome. Utility Model Content

[0005] The purpose of this invention is to provide a miniature speaker for tablet computers, which solves the problem that the casing of existing miniature speakers for tablet computers is difficult to repair.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a miniature speaker for a tablet computer, including a second shell;

[0007] The first shell is installed at the top of the second shell, the third shell is provided on one side of the second shell, the speaker body is installed at one end of the third shell, and the fourth shell is installed at the bottom of the third shell.

[0008] An interface is installed at one end of both the first and third outer shells, a positioning structure is installed on one side of the third outer shell, and a disassembly structure is installed at the top of both the first and third outer shells.

[0009] The disassembly and assembly structure includes a mounting slot installed at the top of the second and fourth outer shells, a mounting hole provided at the top of the mounting slot, and a fixing screw installed at the top of the mounting hole.

[0010] In use, the first and second outer shells form a locking structure, and the third and fourth outer shells form a locking structure. The shells are composed of multiple shells. The locking structure facilitates disassembly and allows the shells to be combined together. The mounting holes and mounting slots cooperate with each other, and the mounting holes and fixing screws form a threaded connection. Tightening the fixing screws allows them to be screwed into the mounting holes and mounting slots, fixing the multiple shells together. When maintenance is required, the fixing screws can be unscrewed to disassemble the shells.

[0011] Furthermore, the bottom of the first outer shell is provided with a locking block, and the top of the second outer shell is provided with a locking groove. The first outer shell and the second outer shell form a locking structure, which facilitates disassembly.

[0012] Furthermore, the surfaces of the first, second, third, and fourth outer shells are all provided with protective structures. The protective structures include an insulating layer installed on the surfaces of the first, second, third, and fourth outer shells, an isolation layer installed on the outside of the insulating layer, and an anti-corrosion coating installed on the outside of the isolation layer. The insulating layer can enhance the insulation of the shell, the isolation layer can protect the shell, and the anti-corrosion coating can enhance the anti-corrosion effect of the shell.

[0013] Furthermore, both sides of the third outer shell and the first outer shell are provided with through holes, which are symmetrically distributed about the central axis of the first outer shell, allowing the outer shell to be installed inside the plate by screws.

[0014] Furthermore, the outer sidewall of the fixing screw is uniformly provided with external threads, and the inner sidewall of the first housing is uniformly provided with internal threads that cooperate with the external threads. The fixing screw and the first housing are threadedly connected, and the fixing screw can fix the housing.

[0015] Furthermore, a positioning structure is installed at the top of the interface. The positioning structure includes a threaded groove at the top of the interface, a threaded rod passing through the inside of the threaded groove, a positioning block installed at the bottom of the threaded rod, and a rotating block installed at the top of the threaded rod. The lifting and lowering of the threaded rod can drive the positioning block to lift and lower to fix the wire.

[0016] Furthermore, the threaded grooves and the threaded rod form a threaded connection. The threaded grooves are arranged at equal intervals at the top of the interface, and the rotation of the threaded rod can drive the threaded grooves to rise and fall.

[0017] The advantages of the miniature speaker for tablet computers provided by this utility model are as follows: during use, the outer shell can be fixed by the disassembly and assembly structure, the outer shell can be disassembled for internal maintenance, the positioning structure can fix the wires of the insertion interface, and the protective structure can protect the surface of the outer shell.

[0018] A second outer shell is installed at the bottom of the first outer shell. The first and second outer shells form an interlocking structure. The third and fourth outer shells also form an interlocking structure. The outer shell is composed of multiple outer shells. The interlocking structure facilitates disassembly and allows the outer shells to be combined together. The mounting holes and mounting slots cooperate with each other. The mounting holes and fixing screws form a threaded connection. Tightening the fixing screws allows them to be screwed into the mounting holes and mounting slots, fixing the multiple outer shells together. When maintenance is required, the fixing screws can be unscrewed to disassemble the outer shell. This achieves the purpose of facilitating the maintenance of the outer shell of the tablet computer's mini speaker.

[0019] By installing a threaded groove at the top of the interface, the threaded groove and the threaded rod form a threaded connection, allowing the conduit to be inserted into the interface and connected to the device. The rotating block can rotate, which in turn drives the threaded rod to rotate, and the rotation of the threaded rod drives the positioning block at the bottom to rise and fall. The rising and falling of the positioning block can fix the conduit and prevent it from shifting or falling off, thereby achieving the purpose of limiting the wires of the tablet computer's miniature speaker.
