[0032] like Figure 1-4 As shown, an embodiment of this utility model provides a waterproof horn structure, including a housing 1, a horn 2, and a locking member 3. The housing 1 has a mounting cavity 4 with an opening on one side. A waterproof sleeve 5 is fitted onto the horn 2 to form a waterproof horn assembly 6. The waterproof sleeve 5 has a first waterproof rib 7 and a second waterproof rib 8. The first waterproof rib 7 is located on the outer surface of the waterproof sleeve 5, and the second waterproof rib 8 is located on the inner wall surface of the waterproof sleeve 5. The waterproof horn assembly 6 is installed inside the mounting cavity 4, with the first waterproof rib 7 abutting against the inner wall of the mounting cavity 4 and the second waterproof rib 8 abutting against the upper end face of the horn 2. The locking member 3 has several locking grooves 9, and several locking hooks 10 corresponding to the locking grooves 9 are provided on the outer side of the mounting cavity 4 on the housing 1. The locking grooves 9 are engaged with the locking hooks 10 for installation. The locking member 3 presses the waterproof horn assembly 6 into the mounting cavity 4. The first waterproof rib 7 and the second waterproof rib 8 are deformed by compression to form a waterproof effect, resulting in good waterproofing and reduced product cost.

[0033] Specifically, the housing 1 serves as the mounting body for the speaker 2, and can be the outer shell of a wearable device. The housing 1 is typically made of plastic or alloy materials. The inner side of the housing 1 forms a mounting cavity 4, which accommodates the speaker 2. The speaker 2 is the sound-producing element, with one end being the sound-producing part 11 and the other end being the bottom, which has good rigidity. The speaker 2 is fitted with a waterproof sleeve 5 to form a waterproof speaker assembly 6, which is then inserted into the mounting cavity 4 for installation. The waterproof sleeve 5 fits snugly between the mounting cavity 4 and the speaker 2, thus achieving waterproofing. More specifically, the waterproof sleeve 5 is preferably a silicone sleeve made of silicone material, produced by injection molding, resulting in lower production costs and helping to reduce the overall production cost of the device. The waterproof sleeve 5 has a frame structure. The outer surface of the waterproof sleeve 5 is provided with a first waterproof rib 7 in a ring structure, and the inner wall surface of the waterproof sleeve 5 is provided with a second waterproof rib 8 in a ring structure. When the horn waterproof component 6 is installed in the mounting cavity 4, the first waterproof rib 7 abuts against the inner wall surface of the mounting cavity 4, and the second waterproof rib 8 abuts against the upper end face of the horn 2. After the horn 2 is installed by pressing it with the locking piece 3, the first waterproof rib 7 and the second waterproof rib 8 are squeezed and deformed, forming a tight waterproof on the contact surface of the first waterproof rib 7 and the second waterproof rib 8 respectively, resulting in a good waterproof effect.

[0034] Furthermore, in this embodiment, in order to enable the horn 2 to press the waterproof sleeve 5 into the mounting cavity 4 and to facilitate the installation of the horn waterproof assembly 6 onto the housing 1, locking hooks 10 are symmetrically arranged on the outer side of the mounting cavity 4 on the housing 1. The number of locking hooks 10 can be set according to actual needs. In this embodiment, two symmetrical locking hooks 10 are provided. Correspondingly, symmetrical locking grooves 9 are provided at both ends of the locking member 3. The locking grooves 9 engage with the locking hooks 10 to install and press the horn waterproof assembly 6, thereby squeezing the waterproof sleeve 5, causing the waterproof sleeve 5 to deform on the first waterproof rib 7 and the second waterproof rib 8 to achieve a sealing and waterproofing effect. Preferably, the locking member 3 is a metal stamping part, which can be formed by stamping stainless steel sheet. The two ends of the locking member 3 are stamped into symmetrical bent portions 17, and the locking grooves 9 are formed on the bent portions 17. This facilitates the quick engagement of the locking grooves 9 into the locking hooks 10 to complete the assembly, making the assembly convenient and quick. More preferably, in order to strengthen the bottom of the speaker 2 so that the locking member 3 will not damage the speaker 2 when it is pressed into the speaker 2, multiple reinforcing ribs 12 are symmetrically provided at the bottom of the speaker 2. The reinforcing ribs 12 protrude from the bottom surface of the speaker 2. The locking member 3 presses into the speaker 2, and the inner surface of the locking member 3 fits against the reinforcing ribs 12 to fasten the locking hook 10.

[0035] Furthermore, in this embodiment, a sound-permeable hole 13 is provided on the upper side of the mounting cavity 4, the sound-permeable hole 13 is connected to the mounting cavity 4, and the sound-producing part 11 of the speaker 2 is installed facing the sound-permeable hole 13. The upper surface of the waterproof sleeve 5 is formed as a sound passage 14, and the sound-producing part 11 of the speaker 2 is installed facing the sound passage 14. Specifically, in order to realize the sound propagation of the speaker 2, the speaker 2 is installed in the mounting cavity 4, and two sound-permeable holes 13 are provided on the upper side of the mounting cavity 4, the sound-permeable holes 13 are connected to the mounting cavity 4, and the sound-producing part 11 of the speaker 2 is installed facing the sound-permeable hole 13, so that the sound emitted by the vibration of the sound-producing part 11 of the speaker 2 can be propagated to the outside of the housing 1 through the sound-permeable hole 13. Preferably, one side of the waterproof sleeve 5 is formed as a rectangular sound passage 14. When the waterproof sleeve 5 is fitted onto the speaker 2, the sound-producing part 11 of the speaker 2 faces the sound passage 14, so that the sound emitted by the speaker 2 can be propagated through the sound passage 14. It should be noted that in some embodiments, a sound-permeable membrane (not shown) can be provided on the sound passage 14 for sealing, thereby serving to protect the speaker 2 from water and dust, and also preventing foreign objects from passing through the sound passage 13 and damaging the speaker 2.

[0036] Further, in this embodiment, the upper end face of the waterproof sleeve 5 is formed as an annular inward-turned portion 15, and the second waterproof rib 8 is disposed on the inner wall of the inward-turned portion 15. The upper end face of the speaker 2 is formed as an annular fitting portion 16, and the upper surface of the fitting portion 16 is fitted with the second waterproof rib 8. The inner side of the fitting portion 16 is the sound-producing part 11 of the speaker 2. Specifically, in order to achieve the fitting installation of the second waterproof rib 8 and the speaker 2, the upper end face of the waterproof sleeve 5 is formed as an annular inward-turned portion 15, the inward-turned portion 15 extends toward the center of the sound port 14, and the second waterproof rib 8 is disposed on the inner wall of the inward-turned portion 15 and extends downward. The upper end face of the speaker 2 is an annular fitting portion 16, the inner side of the fitting portion 16 is the sound-producing part 11 of the speaker 2, and the upper surface of the fitting portion 16 is a plane. When the waterproof sleeve 5 is fitted onto the speaker 2, the fitting part 16 of the speaker 2 can contact and fit with the inward folding part 15 of the waterproof sleeve 5. The second waterproof rib 8 fits onto the fitting part 16 of the speaker 2. When the speaker 2 is pressed, the second waterproof rib 8 is squeezed and deformed, so that the waterproof sleeve 5 and the speaker 2 can fit tightly together, achieving a good waterproof effect.

[0037] Furthermore, in this embodiment, the locking hook 10 is formed as a hanging ear 18, which is symmetrically arranged on the outside of the mounting cavity 4. A guide portion 19 is provided on the hanging ear 18, which is formed as a guide slope and guides the locking groove 9 to engage with the hanging ear 18. Specifically, to facilitate the quick and secure installation of the locking member 3 and the housing 1, the locking hook 10 is formed as a hanging ear 18, with two hanging ears 18 symmetrically arranged on the outside of the mounting cavity 4. The hanging ears 18 extend outward from the outside of the mounting cavity 4, and the ends of the hanging ears 18 are configured as guide slopes to form guide portions 19, which guide the locking groove 9 to quickly engage with the hanging ear 18. It should be noted that in this embodiment, the locking member 3 has a certain elasticity in the bending part 17. When the locking member 3 is fastened to the locking hook 10, the locking member 3 can be opened and fastened into the locking hook 10. Then, the locking member 3 is fastened to the locking hook 10 under the action of the rebound force of the bending part 17, maintaining the pressure of the locking member 3 on the horn waterproof component 6 and stabilizing the horn waterproof component 6 in the installation cavity 4. The installation and disassembly are relatively quick.

[0038] In addition, the embodiments of this utility model also provide a wearable device that uses the above-mentioned waterproof structure of the speaker 2. The outer shell is the housing 1 of the wearable device. The waterproof structure of the speaker 2 is equipped with a waterproof sleeve 5 and a locking fastener 3. The waterproof sleeve 5 is fitted onto the speaker 2, and the speaker 2 is pressed and installed by connecting the housing 1 through the locking fastener 3. The product cost is reduced and the waterproof effect is good, which meets the diversified needs of the market.
