[0027] In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present application.

[0028] The embodiments of the present application will be further described in detail below with reference to the accompanying drawings of the specification.

[0029] Figure 1 It is an exploded view of a loudspeaker provided by an embodiment of the present application. The loudspeaker includes: a housing and a loudspeaker unit. Among them, the housing includes an upper cover 11 and a lower cover 12, and the upper cover 11 and the lower cover 12 form a closed space. The loudspeaker unit is located in the closed space. The loudspeaker unit includes a middle patch 13, and the middle patch 13 contains a resistance wire 23.

[0030] In the above solution, the middle patch contains a resistance wire. On the one hand, the resistance wire increases the rigidity of the middle patch. The increase in the rigidity of the middle patch can extend the audible frequency band of the sound and also smooth the sound, reducing the sudden change of the sound, that is, reducing the possibility of the sound suddenly becoming louder or suddenly becoming smaller. On the other hand, the resistance wire can be energized to generate heat. When there is moisture inside the loudspeaker, the middle patch temperature can be relatively increased by heating the resistance wire, accelerating the evaporation of the moisture. In summary, a loudspeaker provided by the present application not only increases the rigidity of the middle patch, but also has a drainage function, thus improving the performance of the loudspeaker.

[0031] In a possible implementation method, the exploded view of the loudspeaker can also be as Figure 2 shown. The loudspeaker includes a housing and a loudspeaker unit. Among them, the housing includes an upper cover 11 and a lower cover 12, and the upper cover 11 and the lower cover 12 form a closed space. The loudspeaker unit is located in the closed space. The loudspeaker unit includes: a magnetic circuit system, a vibration system and a frame 16. Among them, the magnetic circuit system includes: a pole piece 17, a magnet 18 and a yoke 19; the vibration system includes: a middle patch 13, a diaphragm 14 and a voice coil 15. The pole piece 17 and the magnet 18 are located between the frame 16 and the yoke 19, and the lower part of the frame 16 is clamped to the yoke 19. The voice coil 15 is located between the frame 16 and the diaphragm 14, and the upper part of the frame 16 is clamped to the diaphragm 14. The middle patch 13 is located between the upper cover 11 and the diaphragm 14. Figure 3 It is a cross-sectional view of the loudspeaker.

[0032] In a possible implementation method, the structural diagram of the middle sticker 13 can be as Figure 4 shown. Among them, the middle sticker 13 includes an aluminum foil 21 and a foaming material 22. The foaming material 22 is wrapped by the aluminum foil 21, and a resistance wire 23 is included in the foaming material 22. Figure 5 is a perspective view of the middle sticker 13.

[0033] In the above solution, since the foaming material contains a resistance wire, the rigidity of the foaming material is increased. The increase in the rigidity of the foaming material can extend the audible frequency band of the sound, and can also smooth the sound, reducing the sudden change of the sound, that is, reducing the possibility of the sound suddenly becoming larger or smaller. Therefore, the performance of the speaker is improved.

[0034] In a possible implementation method, the middle sticker 13 can adopt a sandwich structure of aluminum foil 21 / foaming material 22 / aluminum foil 21, and this sandwich structure is as Figure 4 shown. Other structures can also be adopted, and the present application does not limit this.

[0035] In a possible implementation method, the resistance wire 23 is a single-layer planar coil. The structure of its single-layer planar coil can be as Figure 6 , Figure 7 , Figure 8 shown, or it can be other structures, and the present application does not limit this.

[0036] In a possible implementation method, the diameter of the resistance wire 23 is equal to the thickness of the foaming material 22.

[0037] In a possible implementation method, the resistance wire 23 is made of a metal material, and its hardness is greater than that of the foaming material 22. For example, it can be any one of copper, aluminum, nickel, iron-chromium-aluminum alloy, nickel-chromium alloy, etc. The material adopted by the resistance wire 23 and the structure of the single-layer planar coil determine the rigidity of the middle sticker 13. That is, different materials and different structures of resistance wires 23 can be added to the foaming material 22 to determine middle stickers 13 with different rigidities.

[0038] In a possible implementation method, the resistance wire 23 can be energized to generate heat.

[0039] In the above solution, when there is moisture inside the speaker, it will affect the performance of the speaker. This resistance wire can be energized to generate heat, and by heating the resistance wire, the temperature of the middle sticker can be relatively increased, accelerating the evaporation of moisture and improving the performance of the speaker.

[0040] In a possible implementation method, the speaker further includes a built-in program, which is used to control the heating of the resistance wire 23. The circuit system of the resistance wire 23 can be independent of the voice coil circuit of the speaker unit, and the heating of the resistance wire 23 is controlled by the built-in program switch. When there is moisture inside the speaker, the resistance wire 23 is controlled to heat up through the built-in program, so that the temperature of the middle sticker 13 is relatively increased. Since the higher the temperature, the more violent the movement of water molecules, the water can evaporate quickly. After the moisture inside the speaker is emptied, the resistance wire 23 can be controlled by the built-in program to stop heating.

[0041] In the above scheme, when there is moisture inside the speaker, the built-in program can be used to control the heating of the resistance wire, so that the resistance wire heats up, accelerates the evaporation of moisture, and improves the performance of the speaker.

[0042] Although the preferred embodiments of the present application have been described, those skilled in the art may make additional changes and modifications to these embodiments once they have learned the basic creative concept. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications falling within the scope of the present application.

[0043] Obviously, those skilled in the art can make various changes and modifications to the present application without departing from the spirit and scope of the present application. Thus, if these modifications and variations of the present application fall within the scope of the claims of the present application and their equivalents, the present application is also intended to include these modifications and variations.
