Description

Technical Field

[0001] This utility model relates to the field of speaker equipment technology, and in particular to a tweeter column. Background Technology

[0002] The tweeter in a sound column can express sound more completely and allow it to travel a greater distance. To achieve better sound quality, the tweeter should be directed towards the target audience area. Therefore, the angle of the tweeter needs to be adjusted according to specific circumstances to obtain the best effect. In the technical solution of Chinese utility model patent application number 202321409163.6, entitled "A Combined Speaker Box," the mid-high frequency speaker box is located inside the subwoofer enclosure and in front of the subwoofer. The two sides of the mid-high frequency speaker box are rotatably connected to the side walls of the subwoofer enclosure via pivots. The top of the mid-high frequency speaker box has an adjustment plate with adjustment holes, and the side of the subwoofer enclosure has insertion holes. After rotating the mid-high frequency speaker box to a suitable angle, inserting a pin through the insertion hole into the adjustment hole on the adjustment plate locks the angle of the mid-high frequency speaker box. However, this technology still has the following technical problems in use:

[0003] Firstly, in this technical solution, the mid-high frequency speaker is positioned horizontally in front of the woofer. This results in a relatively large width for the mid-high frequency speaker, and its sides are secured by pins inserted into sockets on the side of the woofer enclosure. During operation, both pins must be simultaneously pulled out to rotate the mid-high frequency speaker to the appropriate angle, and then the two pins must be inserted back into the sockets to secure it. This requires two people: one to hold the mid-high frequency speaker while the other inserts and removes the pins, making the operation very inconvenient.

[0004] Secondly, the angle of the mid-high frequency speaker is adjusted by locking the pin into the jack and adjustment hole. Therefore, the adjustment angle of the tweeter can only be a few fixed angles and cannot be continuously adjusted. As a result, the tweeter cannot be aimed very accurately at the target audience area, and the sound effect of the speaker is not very ideal.

[0005] Given the above-mentioned shortcomings of the existing technology, the applicant believes it is necessary to make technical improvements to provide a tweeter column with more precise angle adjustment and more convenient operation. Utility Model Content

[0006] The purpose of this utility model is to solve the above-mentioned problems and shortcomings, and to provide an adjustable tweeter speaker column device. By hinged the upper bracket to the upper cavity wall of the upper chamber and the lower bracket is installed on the lower cavity wall of the upper chamber in a way that can swing back and forth continuously, and then fixing the upper and lower ends of the tweeter to the upper bracket and the lower bracket respectively, the tweeter angle can be continuously adjusted. Moreover, it can be operated by only one person and is very convenient to use.

[0007] The technical solution of this utility model is implemented as follows: an adjustable tweeter speaker column device includes a speaker housing with a lower chamber and an upper chamber. A woofer is installed in the lower chamber, and a tweeter is installed in the upper chamber. Its characteristic is that it also includes a support assembly composed of an upper support and a lower support. The two sides of the upper support are respectively hinged to the two side walls of the upper end of the upper chamber. The two sides of the lower support are respectively mounted on the two side walls of the lower end of the upper chamber, allowing continuous back-and-forth swinging. The upper and lower ends of the tweeter are respectively fixed to the upper support and the lower support. The tweeter is installed in the upper chamber with adjustable direction as the lower support swings back and forth.

[0008] Furthermore, the upper support and the lower support are respectively composed of a horizontal plate for fixing the tweeter and a vertical plate disposed on both sides of the horizontal plate and connected to the cavity wall of the upper chamber.

[0009] Furthermore, the upper chamber has first arc-shaped slots on both sides of the lower end cavity wall, which penetrate the speaker housing. The lower bracket is bolted through the first arc-shaped slots and locked to the longitudinal plate, while being swayably mounted on both sides of the upper chamber cavity wall.

[0010] Furthermore, it also includes an adjustment auxiliary plate with a second arc-shaped slot, the adjustment auxiliary plate being embedded in the speaker housing and the second arc-shaped slot being centered and aligned with the first arc-shaped slot; the diameter of the second arc-shaped slot is smaller than the diameter of the first arc-shaped slot.

[0011] Furthermore, the speaker housing is provided with an mounting groove for mounting an adjustment auxiliary plate.

[0012] Furthermore, the upper bracket is hinged to the cavity wall of the upper chamber by a pin that passes through the speaker housing and the longitudinal plate in sequence.

[0013] The beneficial effects of this utility model are:

[0014] First, in this invention, the hinge end of the tweeter is on top and the adjustment end is on the bottom. This allows for easy adjustment of the tweeter angle by simply pushing the lower end of the tweeter to the appropriate angle with one hand and then fixing it in place. One person can easily adjust the tweeter angle, making the operation more convenient.

[0015] Secondly, the lower bracket can swing back and forth continuously, which allows for continuous adjustment of the tweeter angle. This makes the adjustment more flexible and allows for more precise aiming at the target audience area, resulting in the best speaker performance. Attached Figure Description

[0021] To enable those skilled in the art to better understand the technical solution of this utility model, the technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0022] like Figures 1 to 3 As shown, this utility model provides an adjustable tweeter speaker column device, including a speaker housing 1 with a lower chamber 11 and an upper chamber 12. A woofer 2 is installed in the lower chamber 11, and a tweeter 3 is installed in the upper chamber 12. To achieve the purpose of this utility model, it also includes a support assembly 4 composed of an upper support 41 and a lower support 42. The two sides of the upper support 41 are respectively hinged to the two side walls of the upper end of the upper chamber 12. The two sides of the lower support 42 are respectively mounted on the two side walls of the lower end of the upper chamber 12, which can be continuously oscillated back and forth. The upper and lower ends of the tweeter 3 are respectively fixed to the upper support 41 and the lower support 42. The tweeter 3 is installed in the upper chamber 12 with adjustable direction as the lower support 42 oscillates back and forth.

[0023] In this way, the tweeter can be adjusted by pushing it with one hand to adjust the angle and then fixed in place, making it very convenient to operate. Furthermore, the direction of the tweeter can be adjusted at any angle according to the actual situation, so that the tweeter can be more accurately aimed at the target audience area to obtain the best sound effect.

[0024] like Figure 3 , 4 As shown in Figure 5, for ease of manufacturing and installation, the upper bracket 41 and the lower bracket 42 are respectively composed of a horizontal plate 411 for fixing the tweeter 3 and a vertical plate 412 disposed on both sides of the horizontal plate 411 and connected to the cavity wall of the upper chamber 12. In this way, the upper bracket 41 and the lower bracket 42 are U-shaped, with a simple structure and easy assembly, which helps to control the production cost of the tweeter column.

[0025] like Figure 3 , 4 As shown, to achieve smooth back-and-forth swinging of the tweeter and facilitate manufacturing and operation, the lower side walls of the upper chamber 12 are respectively provided with first arc-shaped slots 121 penetrating the speaker housing 1. The lower bracket 42 is bolted through the first arc-shaped slots 121 and locked to the longitudinal plate 412, while being swayably mounted on the side walls of the upper chamber 12, with the first arc-shaped slots 121 inclined upwards. Loosening the bolts allows the lower end of the tweeter to swing along the first arc-shaped slots 121 to adjust the tweeter's angle, causing it to tilt downwards; tightening the bolts fixes the tweeter, making operation very convenient. Furthermore, the first arc-shaped slots 121 can be made simply by drilling holes in the speaker housing 1, thus enabling the tweeter to swing back and forth. This not only saves time and effort in manufacturing but also avoids additional space requirements, resulting in a simpler overall speaker column structure and helping companies reduce production costs.

[0026] To protect the speaker housing 1 from wear, such as Figures 1 to 3 As shown, the system also includes an adjustment auxiliary plate 5 with a second arc-shaped slot 51. The adjustment auxiliary plate 5 is fitted onto the speaker housing 1, and the second arc-shaped slot 51 is aligned with the first arc-shaped slot 121. The diameter of the second arc-shaped slot 51 is smaller than that of the first arc-shaped slot 121. When the bolt is tightened onto the adjustment auxiliary plate 5 and the lower bracket 42, the first arc-shaped slot 121 only provides a channel for the bolt. This prevents wear on the speaker housing 1 when tightening or loosening the bolt, thus helping to extend the service life of the entire speaker column.

[0027] like Figures 1 to 3 As shown, the speaker housing 1 is provided with an mounting groove 13 for mounting the adjustment auxiliary plate 5. In this way, the surface of the adjustment auxiliary plate 5 can be flush with the surface of the speaker housing 1, preventing the auxiliary plate 5 from scratching with surrounding objects during use and transportation, thereby improving the overall quality of the speaker column.

[0028] like Figure 3 , 4 As shown, the upper bracket 41 is hinged to the cavity wall of the upper chamber 12 by passing through the speaker housing 1 and the longitudinal plate 412 in sequence via a pin. The pin is a standardized fastener, widely used for hinged connections between parts, and is reliable in operation and easy to disassemble. This utility model uses a pin to hinge the upper bracket 41 to the upper chamber 12, which helps to control production costs.
