Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of installation structures, and in particular relates to a fixed installation structure and a speaker box capable of preventing a speaker magnet from falling off. Background Art
[0002] A speaker, primarily composed of a magnet, coil, drum, and diaphragm, converts electrical signals into mechanical waves. Because the wavelength of mechanical waves audible to the human ear is limited, ranging from approximately 1.7 cm to 17 m, and corresponding to a frequency of approximately 20 Hz to 20,000 Hz, typical speakers are designed to produce sound within this range.
[0003] The frequency range of the mechanical waves (sound waves) emitted by a woofer is between 20 and 200 Hz. Since wavelength is inversely proportional to frequency, the woofer's coil drives the diaphragm to vibrate over a longer stroke and with greater amplitude. The woofer's magnet is typically bonded and magnetically secured to a front magnetic plate (washer) with a T-shaped iron core as a guide. The front magnetic plate is typically directly fixed to the bottom of the chassis. When the coil drives the diaphragm to vibrate with greater amplitude during prolonged playback (and / or when the speaker is subjected to external impact), the woofer's magnet and T-shaped iron core may become disconnected from the front magnetic plate (washer) due to adhesive failure or vibration, potentially causing them to fall off. Therefore, the current method for securing woofers in speaker enclosures involves installing a bracket to prevent one end of the woofer's magnet from falling off. The bracket is then screwed from inside the speaker enclosure, passing through the bracket's tabs and mounting holes on the speaker chassis, and then mounted to the main frame. However, removing and installing the bracket and speaker from within the speaker enclosure is inconvenient due to the size of the main frame. Utility Model Content

[0021] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.
[0022] It should be noted that the fixed installation structure of this embodiment to prevent the speaker magnet from falling off is different from the existing technology. The current method of fixing the speakers (especially the subwoofers) in the speaker box is to install a bracket to limit one end of the magnet of the subwoofer to prevent it from falling off, and then use screws from the inside of the speaker box to pass through the bracket ears and the mounting holes on the speaker plate rack and then install it on the main frame inside the speaker box. However, the disassembly and assembly of the bracket and the speaker inside the speaker box is affected by the size of the main frame of the speaker box, and the operation is not convenient.
[0023] See also Figure 1 、 Figure 2 as well as Figure 3 The present embodiment provides a fixed installation structure for preventing the speaker magnet from falling off, comprising: a mounting frame 100 and a speaker 200; the mounting frame 100 has a first through hole 110 for mounting the speaker, and the mounting frame 100 integrally extends a first bracket 120 toward the inside of the first through hole 110 (that is, the first bracket 120 is formed together with the mounting frame 100, for example, by an injection molding process as an integrated injection molding process), and the first bracket 120 can be adapted to fix the speaker magnet of the speaker (one end of the speaker magnet is limited to prevent it from falling off), so that the speaker 200 can only be adapted and installed from the outside of the mounting frame 100 toward the first bracket 120 inside the first through hole 110. The first bracket 120 can prevent the speaker 200 magnet from falling off, and the above-mentioned installation method can realize the disassembly and assembly of the speaker without being from the inside of the speaker (when the mounting frame 100 is the main frame of the speaker), and the disassembly and assembly of the speaker 200 is no longer affected by the size of the main frame of the speaker, and the operation is more convenient. It can be seen that in this embodiment, the first bracket 120 can be grown from the mounting frame 100 (for example, the mounting frame 100 and the first bracket 120 are both made of plastic or other plastic materials). After the speaker is installed, the first bracket 120 can support the speaker magnet to prevent the speaker magnet from falling off due to vibration during falling, etc., thereby playing a good protective role. At the same time, it can also save the labor cost and material cost of the screws required to fix the bracket in the existing technology.
[0024] Furthermore, in this embodiment of a fixed mounting structure for preventing speaker magnets from falling off, a first bracket 120 includes: X connecting rods 121, and a bracket 122 connected to the X connecting rods, where X is a positive integer greater than 1. Bracket 122 is adapted to conform to the outer contour of the speaker magnet (or a combination of a magnet and a T-shaped iron core) of a speaker 200 (e.g., a woofer). Furthermore, each of the X connecting rods 121 is provided with a reinforcing rib 123, which enhances the rigidity of the connecting rods 121.
[0025] Furthermore, in this embodiment of a fixed installation structure for preventing the speaker magnet from falling off, the bracket 122 is annular, the outer diameter of the annular bracket 122 is equal to the outer diameter of the annular magnet of the speaker 200, and the inner diameter of the annular bracket 122 is equal to the inner diameter of the annular magnet of the speaker 200.
[0026] Furthermore, in this embodiment of a fixed installation structure that prevents the speaker magnet from falling off, the speaker 200 can only be installed with the speaker magnet side of the speaker 200 as the mating direction, and is adapted to be installed from the outside of the mounting frame 100 toward the first bracket 120 inside the first through hole 110, so that the first bracket 120 is adapted to the speaker magnet of the speaker 200, and the mounting hole 210 of the speaker 200 is exactly adapted to the external mounting hole of the mounting frame 100. The mounting hole 210 of the speaker 200 is located on the disc frame of the speaker 200. Specifically, the speaker 200 of this embodiment is a woofer.
[0027] Furthermore, in the present embodiment of a fixed installation structure for preventing the speaker magnet from falling off, the installation frame 100 and the back cover (not shown in the figure) and the side passive diaphragm (not shown in the figure) can form a bass sealed chamber.
[0028] In addition, this embodiment also provides a speaker, which has the fixed mounting structure mentioned in any of the above embodiments to prevent the speaker magnet from falling off, and the mounting frame of the fixed mounting structure is specifically the main frame (front shell) of the speaker. Furthermore, the speaker is also installed with other speakers (such as mid-range speakers, tweeters, etc.), and the other speakers are installed on the mounting frame 100 from the outside of the mounting frame 100 toward the inside of the second through hole (such as 140) of the mounting frame 100. The mounting holes of the other speakers are located on the disc rack of the other speakers, and the other speakers are sealed by an isolation cover inside the second through hole of the mounting frame 100 to form an independent chamber (for example, the left mid-range speaker and the isolation cover L are sealed from the inside of the mounting frame 100 to form an independent chamber, and the right mid-range speaker and the isolation cover R are sealed from the inside of the mounting frame 100 to form an independent chamber).
[0029] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements or improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
