The terms used in the specification of the present utility model are only for the purpose of describing specific embodiments and are not used to limit the present utility model. The term "and / or" used in this specification includes any and all combinations of one or more related listed items.

[0023] In addition, the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0024] like Figure 1-Figure 2As shown, the present application provides an embodiment of a high-bass separation speaker with clear bass. The high-bass separation speaker with clear bass includes a box body 1 and a cover plate 3. The cover plate 3 is fixed to the outside of the box body 1 and closes the box body 1 to form a bass vibration chamber 2. The bass speaker 4 is fixed on the cover plate 3. On the box body 1, a plurality of vibration holes (not shown in the figure) are provided on the inner wall of the bass vibration chamber 2. Each vibration hole is correspondingly covered and installed with a bass diaphragm 5. The size of the vibration hole matches the bass diaphragm 5 covered thereon. In the speaker of this embodiment, the high and low frequencies are played in a frequency division. In addition to the bass vibration chamber 2, the interior of the box is also provided with a mid-high frequency vibration chamber. The bass vibration chamber 2 and the mid-high frequency vibration chamber are not connected to each other. The music frequency division is processed to prevent the interference between the mid-high frequency and the bass. The bass speaker 4 is fixed on the cover plate 3. The paper cone mouth of the bass speaker 4 passes through the cover plate 3 toward the outside of the cover plate 3. When the bass speaker 4 vibrates and sounds, the air in the bass vibration chamber 2 will also vibrate with the vibration of the bass speaker 4. In the composition of music, the bass part often carries the rhythm and emotional tone, and is an indispensable part of the music experience. The bass vibration chamber 2 optimizes the transmission and reflection of low-frequency sound effects, making the bass fuller, deeper, and more layered. This enhanced effect not only makes the music sound more three-dimensional and full, but also enhances the emotional expressiveness of the music. The bass diaphragm 5, which is directly attached to the inner wall of the bass vibration chamber 2, can vibrate with the vibration of the air in the bass vibration chamber 2, and further regulate the sound quality and volume of the bass through its own vibration and reflection. The synergistic effect of the vibration hole and the bass diaphragm 5 thereon can buffer and release the pressure inside the bass vibration chamber 2, thereby facilitating the penetration of the bass, eliminating the problem of the dullness of the bass, and making the bass effect clear and full, so that the music performance is clearer, fuller and more layered, bringing a more shocking auditory experience to the audience. The sound insulation board in the box body 1 facing the cover plate 3 and forming the front and rear closed surfaces with the cover plate 3 is made of nano-board. When the pressure of the bass vibration cavity 2 is generated, the nano-board is easily deformed due to the impact. The impact and release of the pressure inside the vibration cavity by the bass diaphragm 5 reduces the deformation of the nano-board, which helps to reduce the vibration of the box body 1. The bass diaphragm 5 can also absorb the interference noise generated by the vibration of the box body 1 to a certain extent, and improve the realism of music playback. The bass diaphragm 5 is fixed by pasting, and the installation method is simple and convenient, which helps to reduce the time cost of production.

[0025] In one embodiment, the bass diaphragm 5 is glued and fixed to the side walls of the bass vibration chamber 2, and multiple bass diaphragms 5 are symmetrically arranged. Figure 2 As shown, in the present embodiment, there are four bass diaphragms 5 , which are respectively distributed in pairs at the lower ends of both sides of the bass vibration cavity 2 , and the two bass diaphragms 5 on each side are arranged up and down.

[0026] like Figure 3As shown, in one embodiment, the bass diaphragm 5 may be square. In other embodiments, the bass diaphragm 5 may also be circular or racetrack-shaped. The shape of the bass diaphragm 5 will not affect its buffering and release of the pressure in the bass vibration chamber 2.

[0027] In one embodiment, the box body 1 is a square cavity structure. The regular shape structure helps to reduce the difficulty of assembling the speaker.

[0028] In one embodiment, the bass diaphragm 5 is made of rubber. Due to the structural characteristics of rubber, the bass diaphragm 5 has good elasticity, and the speaker of the bass diaphragm 5 can repeatedly expand and contract and rebound, so that the pressure inside the cavity is effectively buffered and released.

[0029] In one embodiment, the cover plate 3 is a transparent tempered glass plate. Tempered glass has high strength, which not only helps to reduce the vibration noise of the box, but also the surface is easy to wipe and clean, and the surface is not easy to be scratched during subsequent use, so as to maintain the aesthetics of the box. Due to the structural characteristics of the tempered glass plate, the tempered glass plate has excellent sound insulation performance, which can effectively block and reduce the propagation of sound and has high strength and durability. During its production, it will be heated and then quenched, and the strength and impact resistance of the tempered glass plate will be significantly improved. It can resist external pressure and impact, is not easy to break or damage, and is a safe and reliable sound insulation material. The aesthetics of the tempered glass plate is also one of its advantages. The tempered glass layer has good light conductivity and strength, and its transparent or translucent characteristics allow light to penetrate, maintaining the transparency and openness of the space. At the same time, the tempered glass plate can also be customized and processed as needed to meet design requirements.

[0030] In one embodiment, there is one bass speaker 4, and it is fixed at the center of the tempered glass plate. The center of the tempered glass plate is fixed so that the sound wave vibration center of the bass speaker 4 is at the center of the bass vibration chamber 2, and the divergence to the surroundings remains symmetrical, ensuring the authenticity of the sound and reducing the influence of the sound wave reflecting and interfering on the inner wall of the vibration chamber.

[0031] In one embodiment, a pressure strip 6 is provided on the outer side of the periphery of the cover plate 3, and the pressure strip 6 is screwed to the box body 1 to crimp and fix the cover plate 3 to the box body 1. An outer frame 7 is provided on the outer side of the pressure strip 6, and the outer frame 7 covers the pressure strip 6. The pressure-connection and fixation of the pressure strip 6 allows a larger contact surface between the inner side of the tempered glass plate and the box body 1, which helps to improve the sealing between the tempered glass plate and the box body 1, thereby improving the sealing of the bass vibration chamber 2, improving the effect of the bass vibration chamber 2 in enhancing and adjusting the low-frequency sound effects, and improving the music playback effect. The outer frame 7 covers the pressure strip 6, isolating the outside world from the pressure strip 6, which not only makes the lines of the speaker smoother and makes the appearance more beautiful, but also facilitates the cleaning of the outside of the speaker.

[0032] It should be understood that those skilled in the art can make improvements or changes based on the above description, and all these improvements and changes should fall within the scope of protection of the claims attached to the utility model.

[0033] The above is an exemplary description of the utility model patent in conjunction with the accompanying drawings. It is obvious that the implementation of the utility model patent is not limited to the above-mentioned method. As long as various improvements are made by adopting the method concept and technical solution of the utility model patent, or the concept and technical solution of the utility model patent are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
