DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-6 The utility model provides a technical solution: a double L module type deep waterproof speaker, including a front pressing block 100 of a ring-shaped enclosure structure, a rear pressing block 200, a vibration membrane 300 and a waterproof fitting connection mechanism 400.

[0021] When the front pressing block 100 and the rear pressing block 200 are buckled together, the vibration membrane 300 can be clamped, and at the same time, the vibration membrane 300 can be fixed and sealed by using the waterproof fitting connection mechanism 400, so that the speaker has a deep waterproof effect.

[0022] Among them, a flat pressing portion 110 is provided at the bottom of the front pressing block 100;

[0023] Specifically, the setting of the pressing portion 110 can press down the vibration membrane 300 when the front pressing block 100 and the rear pressing block 200 are buckled. At the same time, the flat pressing portion 110 can better press the vibration membrane 300, and the flat pressing portion 110 can also be conveniently applied with glue to bond and fix the vibration membrane 300.

[0024] The top of the rear pressing block 200 is provided with a ring-shaped groove 210, and the ring-shaped groove 210 is sleeved with the edge of the lower pressing portion 110 and the front pressing block 100 to form a buckle position 220 with an L-shaped cross-sectional structure;

[0025] Specifically, the provided ring-shaped groove 210 can be used to accommodate the buckled front pressure block 100, and when the front pressure block 100 is buckled in the ring-shaped groove 210, the edge of the lower pressure portion 110 and the front pressure block 100 can form a buckle position 220 with an L-shaped cross-section structure in the ring-shaped groove 210. The formed buckle position 220 can be used to buckle the edge of the vibration membrane 300 over a large area, thereby increasing the installation firmness between the vibration membrane 300 and the rear pressure block 200 and the front pressure block 100.

[0026] The vibration membrane 300 is placed between the front pressing block 100 and the rear pressing block 200, and the edge of the vibration membrane 300 is placed in the buckle position 220 to form an L-shaped folding portion 310;

[0027] Specifically, when the edge of the vibration membrane 300 is placed in the buckle position 220, the edge of the vibration membrane 300 forms an L-shaped folding portion 310, which does not damage the vibration membrane 300 and can further ensure the firmness of the installation between the vibration membrane 300 and the rear pressure block 200 and the front pressure block 100.

[0028] Among them, the waterproof fitting connection mechanism 400 includes a first glue layer 410 applied to the bottom of the lower pressing part 110 and the edge of the front pressing block 100, and the first glue layer 410 is bonded and fixed to the top edge of the folding part 310. The waterproof fitting connection mechanism 400 also includes a second glue layer 420 applied to the inside of the ring-shaped groove 210, and the second glue layer 420 is bonded and fixed to the bottom edge of the folding part 310. The first glue layer 410 and the second glue layer 420 bond the folding part 310 to the buckle position 220 and form an L-shaped double-loop waterproof seal.

[0029] Specifically, a first adhesive layer 410 is applied to the bottom of the lower pressing part 110 and the edge of the front pressing block 100. When the folding part 310 is buckled into the buckle position 220, the folding part 310 and the front pressing block 100 can be sealed and bonded to each other. A second adhesive layer 420 is applied to the ring-shaped groove 210 to seal and bond the folding part 310 and the rear pressing block 200. Compared with the traditional vibration membrane 300 connected by a glue laminated splicing structure design, the waterproof coating and adhesive fixing area of ​​the vibration membrane 300 are increased by twice or more, and at the same time, the tearing strength of the vibration membrane 300 is effectively increased, and the tearing destructive force of deep water pressure on the vibration membrane 300 and the waterproof coating is solved, thereby achieving a deep waterproof effect.

[0030] When the front pressing block 100 and the rear pressing block 200 are pressed together, the top of the front pressing block 100 is kept flush with the notch of the ring-shaped groove 210 .

[0031] Specifically, after being buckled, the top of the front pressing block 100 is kept flush with the notch of the ring-shaped groove 210, which can effectively ensure the aesthetics of the speaker.

[0032] In this embodiment, the front pressing block 100 is in a circular ring shape, a square frame shape or a racetrack shape.

[0033] Specifically, a front pressure block 100 in a circular, square or track shape is selected. When the front pressure block 100 is buckled into the ring-shaped groove 210, a buckle position 220 with an L-shaped cross-section structure can also be formed, and the folding portion 310 can also be pressed and fixed.

[0034] In this embodiment, a magnet 500 fixedly mounted inside the rear pressure block 200 is provided at the bottom of the vibration membrane 300 , a voice coil 600 is embedded inside the magnet 500 , and a magnetic bowl 700 is sleeved outside the magnet 500 .

[0035] Specifically, when the voice coil 600 is energized, a magnetic field that changes with the current is generated. The magnetic field interacts with the magnetic field of the magnet 500 to vibrate the diaphragm 300, thereby causing the speaker to produce sound.

[0036] In this embodiment, a speaker bracket 800 is mounted on the exterior of the front pressing block 100 , the rear pressing block 200 and the magnetic bowl 700 .

[0037] Specifically, the components inside the speaker can be protected by installing the speaker bracket 800. At the same time, the speaker bracket 800 can also be shaped and processed so that the speaker has different appearances to adapt to the installation of different product equipment.

[0038] The contents not described in detail in this specification belong to the prior art known to professional and technical personnel in the field. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for technical personnel in the field to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
