Abstract
Description
Technical Field
[0001] This utility model relates to the field of audio technology, and in particular to a matrix-type subwoofer auxiliary structure for KTV all-in-one machines. Background Technology
[0002] To improve the bass effect, most KTV all-in-one audio systems on the market mainly adopt two solutions: the first is to add an additional independent subwoofer, and the second is to increase the power of the subwoofer amplifier. Both of these methods increase the cost of achieving subwoofer.
[0003] If the first solution is adopted, the produced equipment will clearly deviate from the category of KTV all-in-one machines and become a traditional KTV speaker, using a separate subwoofer for bass compensation. The addition of a separate subwoofer will increase costs, as will packaging and transportation costs, and it will be inconvenient for consumers to install and use.
[0004] If the second solution is adopted, a more powerful subwoofer must be installed inside the all-in-one unit. This would require a corresponding increase in the size of the all-in-one unit, and using a more powerful subwoofer is often counterproductive. If not handled properly, the subwoofer effect will not be optimal. For example, adding a more powerful subwoofer to a small KTV all-in-one unit can cause the unit to resonate and distort. Utility Model Content
[0005] In view of the above, it is necessary for this utility model to provide a super bass auxiliary structure that is simple in structure, small in size and has better bass effect.
[0006] The technical solution of this utility model is as follows:
[0007] A matrix-type subwoofer auxiliary structure for a KTV all-in-one machine includes a cabinet, several speaker components, and an auxiliary structure. The speaker components include a subwoofer, which is mounted on the surface of the cabinet near the ground and extends into the cabinet. The auxiliary structure is mounted on the surface of the cabinet where the subwoofer is installed. The center of the auxiliary structure corresponds to the center of the subwoofer. It includes several sound guide tubes and a bass diaphragm sealed at one end of each sound guide tube. The sound guide tubes are arranged around the subwoofer, and the bass diaphragm is located at the end of the sound guide tubes inside the cabinet.
[0008] Furthermore, the enclosure includes a mounting cabinet and a panel. The mounting cabinet is rectangular and includes three chambers arranged in a straight line. The panel is installed on the front of the mounting cabinet to seal the chambers. The middle chamber is used to install a subwoofer.
[0009] Furthermore, each of the four corners of one side of the mounting cabinet is provided with a support leg, which is located on the side where the subwoofer is installed, and is used to isolate the cabinet from the ground.
[0010] Furthermore, the side of the cavity opposite to where the subwoofer is installed is made into a smooth surface, which facilitates the reflection of the vibration generated by the subwoofer onto the bass diaphragm.
[0011] Furthermore, the speaker assembly also includes several mid-range speakers and two tweeters. The several mid-range speakers and two tweeters are all disposed on the panel. The several mid-range speakers are symmetrically disposed on both sides of the display screen and located in the remaining two cavities. The two tweeters are disposed at both ends of the panel and are located in the same two cavities as the mid-range speakers.
[0012] Furthermore, several of the aforementioned sound guide tubes are arranged around the periphery of the subwoofer, with one end of the sound guide tube protruding outside the enclosure and the other end located inside the enclosure, close to the side opposite the subwoofer.
[0013] Furthermore, the bass diaphragm is an arc-shaped diaphragm, installed at one end of the sound guide tube located inside the cavity, with the arc-shaped convex side facing outwards from the sound guide tube.
[0014] Furthermore, the mounting cabinet is provided with ventilation holes, which are located on the side of the central chamber opposite the panel, allowing the chamber to communicate with the outside.
[0015] Compared to existing technologies, this utility model provides a matrix-type subwoofer auxiliary structure for KTV all-in-one machines. This structure involves arranging an even number of sound guide tubes around a subwoofer speaker, extending towards the side opposite the subwoofer speaker. A bass diaphragm is mounted at the end of each sound guide tube, working in conjunction with the subwoofer speaker to enhance its bass amplifier effect. The subwoofer auxiliary structure provided by this utility model is small in size and simple in structure, effectively dissipating bass pressure and significantly improving the subwoofer's performance.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. In the absence of conflict, the embodiments and features in the embodiments of this application can be combined with each other. The present utility model will be described in detail below with reference to the accompanying drawings and embodiments.
[0022] Please see Figures 1-3 A matrix-type subwoofer auxiliary structure for a KTV all-in-one machine includes a cabinet 1, several speaker components 2, and an auxiliary structure 3. Each speaker component 2 includes a subwoofer 21, which is mounted on the surface of the cabinet 1 near the ground and extends into the cabinet 1. The auxiliary structure 3 is located on the surface of the cabinet 1 where the subwoofer 21 is mounted, and the center of the auxiliary structure 3 corresponds to the center of the subwoofer 21. The auxiliary structure 3 includes several sound guide tubes 31 and a bass diaphragm 32 sealed at one end of each sound guide tube 31. The sound guide tubes 31 are arranged around the subwoofer 2, and the bass diaphragm 32 is located at the end of the sound guide tubes 31 inside the cabinet 1. The change in airflow within the cabinet 1 causes the bass diaphragm 32 to vibrate, and the vibration generated by the bass diaphragm 32 is transmitted to the outside of the cabinet 1 through the sound guide tubes 31, enhancing the sound effect of the subwoofer 21.
[0023] Specifically, the enclosure 1 includes a mounting cabinet 11 and a panel 12. The mounting cabinet 11 is rectangular and includes three chambers 111 arranged in a straight line. The panel 12 is mounted on the front of the mounting cabinet 11 to seal the chambers 111. The middle chamber 111 is used to mount a subwoofer 21 for sound playback. The side of this chamber 111 opposite to the subwoofer 21 is made into a smooth surface to reflect the vibrations generated by the subwoofer 21 onto the bass diaphragm 32, causing the bass diaphragm to vibrate in the same way. A display screen 13 is mounted in the center of the panel 12 for touch selection and displaying playback information.
[0024] Furthermore, each of the four corners of one side of the mounting cabinet 11 is provided with a support foot, which is located on the side where the subwoofer 21 is installed. This support foot is used to isolate the cabinet 1 from the ground, so that a gap is formed between the side where the subwoofer 21 is installed and the ground, which facilitates the diffusion of the sound emitted by the subwoofer 21.
[0025] To prevent the vibration airflow generated by the middle woofer 21 from colliding and causing noise, the mounting cabinet 11 is also provided with a ventilation hole 112. The ventilation hole 112 is located on the side of the middle chamber 111 opposite to the panel 12, so that the chamber 111 is connected to the outside, which facilitates the exchange of the vibrating airflow in the chamber 111 with the outside, and avoids the airflow in the chamber 11 colliding and interfering with the bass diaphragm 32, thereby affecting the super bass effect.
[0026] The speaker unit 2 also includes several mid-range speakers 22 and two tweeters 23. The mid-range speakers 22 and two tweeters 23 are all disposed on the panel 12. The mid-range speakers 22 are symmetrically arranged on both sides of the display screen 13 and located within the remaining two chambers 111, resulting in a better stereo effect when the mid-range speakers 22 play sound. The two tweeters 23 are respectively disposed at both ends of the panel 12 and are located within the same two chambers 111 as the mid-range speakers 22.
[0027] Several sound guide tubes 31 are disposed within the cavity 111 in the middle of the enclosure 1 to diffuse bass pressure. These sound guide tubes 31 are arranged in a matrix around the subwoofer 21 to assist the subwoofer 21 in producing bass frequencies. One end of each sound guide tube 31 protrudes outside the enclosure 1 to facilitate sound transmission outside the enclosure 1, while the other end is located inside the enclosure 1, close to the side opposite the subwoofer 21. Understandably, the sound guide tubes 31 can be configured as speaker tubes to further amplify the bass frequencies generated by vibration.
[0028] The bass diaphragm 32 is an arc-shaped diaphragm installed at one end of the sound guide tube 32 located inside the chamber 111, with the arc-shaped convex side facing outwards from the sound guide tube 31. This allows for better reception of vibrations generated by the subwoofer 21. When the subwoofer 21 vibrates, the vibration is transmitted to the chamber 111, causing the gas inside the chamber to vibrate synchronously. The gas flows during vibration, transmitting the vibration frequency to the bass diaphragm 32, causing it to vibrate in sync with the sound and produce sound. The sound generated by the bass diaphragm 32 is diffused outwards through the sound guide tube 31, enhancing the bass effect produced by the subwoofer 21.
[0029] When using this auxiliary structure in a KTV all-in-one unit, an even number of sound guide tubes surround the subwoofer, extending towards the side opposite the subwoofer. The bass diaphragm is mounted at the end of each sound guide tube, working in conjunction with the subwoofer. The subwoofer is driven by a subwoofer amplifier to vibrate and produce sound. The vibration is reflected from the side of the sealed chamber opposite the subwoofer, guiding the airflow generated by the subwoofer to the bass diaphragm. The bass diaphragm vibrates at the same frequency as the vibrating airflow, and the sound generated is transmitted through the sound guide tubes to the outside of the enclosure, thus assisting the subwoofer and improving the subwoofer amplifier's effect. This subwoofer auxiliary structure is small in size and simple in design, effectively dispersing bass pressure and enhancing the subwoofer's performance.

Any equivalent structural or procedural transformations made using the content of this utility model specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
