Description

Technical Field

[0001] The utility model relates to the field of loudspeakers, in particular to a waterproof loudspeaker with a bracket. Background Art

[0002] With the rapid development of technology and the increasing demand of consumers for the durability of electronic products, waterproof function has become an important consideration in the design of electronic products. When traditional electronic products are exposed to water or humid environments, their internal circuits and key components are easily damaged, resulting in device failure or performance degradation.

[0003] In order to achieve the waterproof function of electronic products, two strategies are currently commonly adopted in the industry: one is to prevent moisture from entering the interior of electronic products through overall structural sealing; the other is to enhance the waterproof performance of internal components to ensure that they can maintain normal working conditions even in the event of moisture intrusion.

[0004] Among the internal components, sound-generating components such as speakers, horns, and buzzers have higher requirements for waterproof performance due to their structural characteristics and functional requirements. These components often have open sound holes or vents, allowing moisture to easily enter the interior of the device through these openings. Once moisture invades the back cavity of sound-generating components such as speakers, it will not only affect its sound effect, but may also penetrate into the core circuit area of ​​the electronic product through the internal connection lines, causing an internal short circuit, thereby damaging the entire device.

[0005] Therefore, how to design a technical solution that is effective in waterproofing and maintaining the normal operation of sound-generating components has become an urgent problem to be solved in the field of electronic product design. Utility Model Content

[0012] The upper end of the side of the single-body positioning bracket is provided with a folded edge extending outward, and the single-body positioning bracket is mounted on the lower step of the side of the limiting cavity through the folded edge.

[0013] The connection between the circumference of the single-body positioning bracket and the front shell is fully coated with curing glue.

[0014] Specifically, the curing glue adopts UV glue.

[0015] Furthermore, the monomer positioning bracket is provided with a positioning cavity, and the positioning monomer is arranged in the positioning cavity.

[0016] The upper end surface of the positioning cavity is an inclined surface inclined toward the inner monomer, and a long strip of glue sinking groove B is provided on the side of the inclined surface close to the monomer. No glue sinking groove B is provided on the inclined surface at the bending part of the side edge of the positioning cavity. A support ring extending inward is provided on the lower end surface of the side edge of the positioning cavity.

[0017] The monomer is mounted on the support ring of the positioning cavity.

[0018] The connection between the circumference of the monomer and the monomer positioning bracket is fully coated with curing glue.

[0019] Specifically, the monomer divides the inner cavity into a front sound cavity and a rear sound cavity, a sound outlet hole connected to the front sound cavity is provided on the front shell, the monomer and the monomer positioning bracket are sealed with glue, and after ultrasonic welding between the monomer positioning bracket and the front shell, secondary sealing is performed by applying glue to prevent moisture from entering the rear sound cavity from the front sound cavity.

[0020] Furthermore, the rear shell and the front shell are fixed by ultrasonic welding, and the joint between the overall shell and the rear acoustic cavity is completely sealed, thereby preventing moisture from entering the interior of the electronic product through the overall structural sealing.

[0021] Furthermore, the monomer includes a tweeter and a woofer separated from the tweeter.

[0022] Furthermore, the side edge of the front shell is provided with an opening groove for guiding the wire for welding the single pad, and there is an angle between the opening groove and the side edge, and the angle ranges from 30-90°.

[0035] The monomer 3 is installed in the monomer positioning bracket 2. The monomer 3 includes a tweeter 31 and a woofer 32 separated from the tweeter 31. The two monomers are positioned simultaneously by the monomer positioning bracket 2, which simplifies the structure, improves the space utilization, and improves the positioning accuracy.

[0036] The front shell 1 is provided with a limiting cavity in the inner cavity, and the single-body positioning bracket 2 is arranged in the limiting cavity.

[0037] The side of the limiting cavity adopts a step-shaped structure, and the side of the limiting cavity includes an upper step 11 away from the side of the single-body positioning bracket 2 and a lower step 12 close to the side of the single-body positioning bracket 2. The upper step 11 is protruding from the lower step 12, and the upper end surface of the upper step 11 adopts an inclined surface inclined toward the lower step 12.
