Description

Technical Field

[0001] The utility model relates to the technical field of speaker grilles, in particular to a precise microporous speaker grille. Background Art

[0002] With the popularity of electronic products with speakers such as televisions and stereos, objects with speakers can be seen everywhere around us. The sound-generating principle of the speaker unit is a conversion of electrical energy into sound. When different electronic energies are transmitted to the coil, the coil generates an energy that interacts with the magnetic field of the magnet. This interaction causes the paper plate to vibrate. Because the electronic energy changes at any time, the coil of the speaker will move forward or backward, so the paper plate of the speaker will move with it. This action causes the density of the air to change and produce sound. The function of the microporous speaker mesh cover is to protect the sound-generating membrane at the speaker outlet.

[0003] After searching, a Chinese patent discloses a speaker grille (authorization announcement number CN207753822U), including a fixing ring, a mounting ring and a dust cover ring, a fixing block is installed on the lower side of the fixing ring, a first card slot is provided inside the fixing block, a first magnet is installed at the bottom of the first card slot, a screw hole is installed at the edge of the fixing ring, a rubber ring is installed on the upper side of the fixing ring, a mounting ring is installed above the fixing ring, and a second card slot is provided on the upper side of the mounting ring, a fixing column is installed on the lower side of the mounting ring, and a second magnet is installed on the lower end of the fixing column, an iron net is installed on the inner side of the mounting ring, a dust cover ring is installed above the mounting ring, a reinforcement rib is installed on the inner side of the dust cover ring, and a dustproof net is installed on the reinforcement rib, and a card block is installed on the lower side of the dust cover, although the patent technology can be used in conjunction with a fixing block with a first card slot installed on the fixing ring and a fixing column installed on the mounting ring, it is easy to install.

[0004] However, the above device still has some shortcomings in actual use. The most obvious one is that the prior art fixes the mounting ring by attracting each other between a first magnet installed at the bottom of the first slot and a second magnet at the lower end of the fixing column. However, when current flows through the coil, the armature will be magnetized and produce attraction and repulsion with the magnet, while driving the diaphragm to move, causing the speaker to produce a hoarse sound, which will in turn affect the use of electronic equipment such as audio equipment. At the same time, the prior art protects the speaker through a dustproof net and an iron net, but the dustproof net and the iron net have gaps and cannot play a waterproof role. If the sounding membrane in the speaker unit comes into contact with water, it will affect the sound quality of the speaker unit. Utility Model Content

[0029] When the electronic device needs to be used, the protective circular plate 3 can be removed from the mounting ring 2, thereby reducing the impact of the protective circular plate 3 on the sound of the speaker. When the electronic device is idle, the protective circular plate 3 can be installed on the mounting ring 2 to prevent the speaker from being hit by the outside world and reduce the entry of dust. At the same time, the sealing ring 5 on the protective circular plate 3 will be engaged with the sealing groove 4 in the mounting ring 2, thereby preventing external water from flowing into the mounting ring 2, thereby playing an important waterproof effect on the speaker. When the mounting ring 2 needs to be installed in the fixing ring 1, the threaded rod 20 can be screwed to drive the corresponding slider 15 to slide on the inner wall of the slide groove 14. Through the resistance of the slider 15, the push block 16 will be pushed to slide in the slide groove 14, thereby driving the clamping block 18 to clamp with the corresponding second clamping groove 19, thereby achieving the fixing of the mounting ring 2. Compared with the magnetic adsorption installation method in the prior art, this method does not need to use a magnet, thereby avoiding the attraction and repulsion phenomenon of the armature when current flows through the coil, thereby ensuring the normal use of the speaker in the electronic device.

[0030] Reference Figure 1 and Figure 4 The top and bottom of the protective circular plate 3 are fixedly connected with an L-shaped card plate 6, and a slot 7 is opened inside the L-shaped card plate 6. Both ends of the inside of the mounting ring 2 are opened with a first card slot 9, and the L-shaped card plate 6 is snap-connected with the corresponding first card slot 9.

[0031] By using the L-shaped clamping plate 6 and the first clamping groove 9 in coordination, the protective circular plate 3 can have a certain degree of stability when in use.

[0032] Reference Figure 4A fixing groove 11 is provided inside the mounting ring 2 and is located above the first card slot 9. A card rod 8 is slidably connected inside the fixing groove 11. The outer side of the card rod 8 is fixedly connected to a limiting plate 10. A first spring 12 is sleeved on the outer side of the card rod 8 and is located above the limiting plate 10. The bottom end of the card rod 8 extends to the inside of the first card slot 9 and is engaged with the slot 7.

[0033] Through the elastic force of the first spring 12, the limit plate 10 can be pushed downward in the fixed groove 11, and then the clamping rod 8 can be driven to engage with the corresponding slot 7. On the basis of the clamping of the L-shaped clamping plate 6 and the first clamping groove 9, the connection relationship between the mounting ring 2 and the protective circular plate 3 is enhanced, thereby further improving the fixation of the protective circular plate 3, making the protective circular plate 3 more stable during use and less prone to shaking.

[0034] Reference Figure 1 The top end of the clamping rod 8 extends to the outside of the mounting ring 2 and is fixedly connected with a pull ring, and the end of the threaded rod 20 away from the slider 15 extends to the outside of the mounting ring 2 and is fixedly connected with an adjusting knob.

[0035] The pull ring is provided to facilitate unlocking of the protective circular plate 3 , and the adjusting knob is provided to facilitate rotating the threaded rod 20 , thereby facilitating installation and removal of the mounting ring 2 .

[0036] Reference Figure 1 The outer side of the protective circular plate 3 is coated with polyurethane waterproof coating.

[0037] By using the polyurethane waterproof coating, the outer side of the protective circular plate 3 can have a certain waterproof effect.

[0038] Reference Figure 5 The sliding block 15 and the pushing block 16 are both provided with inclined surfaces on their adjacent sides.

[0039] The inclined surface is provided so that the sliding block 15 can better push the pushing block 16 to move.

[0040] Working principle: Through the elastic force of the first spring 12, the limit plate 10 can be pushed down in the fixing groove 11, and then the clamping rod 8 can be driven to engage with the corresponding slot 7, and on the basis of the engagement between the L-shaped clamping plate 6 and the first clamping groove 9, the connection relationship between the mounting ring 2 and the protective circular plate 3 is enhanced, so that the protective circular plate 3 is more stable when closed and is not easy to shake. Through the setting of the protective circular plate 3, the speaker can be reduced from external collisions and the entry of dust can be reduced, thereby improving the service life of the speaker in the electronic device. Through the use of polyurethane waterproof coating, the outer side of the protective circular plate 3 can have a certain waterproof effect. When the protective circular plate 3 is closed, the sealing ring 5 will be engaged with the sealing groove 4, thereby preventing external water from flowing into the mounting ring 2, thereby further improving the waterproof effect on the speaker.

[0041] When it is necessary to install the mounting ring 2 in the fixing ring 1, the adjusting knob can be turned to drive the threaded rod 20 to rotate, and drive the corresponding slider 15 to slide on the inner wall of the slide groove 14. Through the interference of the slider 15, the pushing block 16 will be pushed to slide in the slide groove 14, and then the clamping block 18 can be driven to engage with the corresponding second clamping groove 19, so that the mounting ring 2 can be fixed. Compared with the magnetic adsorption installation method in the prior art, this method does not require the use of magnets, thereby avoiding the attraction and repulsion of the armature when current flows through the coil, thereby ensuring the normal use of the speaker in the electronic device. When the mounting ring 2 needs to be disassembled, it is only necessary to reverse the threaded rod 20, and the pushing block 16 that loses the interference will be pushed by the elastic force of the second spring 17, which will cause the pushing block 16 to reset.
