Detailed Implementation

[0028] 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. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] like Figures 1-6As shown, this utility model provides a sound field diffusion speaker, which includes a speaker enclosure 1, a woofer 2, a tweeter 3, and a front fixing plate 4. The speaker enclosure 1 is configured with a trapezoidal structure, with the bottom plate 11 of the speaker enclosure 1 being wider than the top plate 12. The front fixing plate 4 is fixed to the front end of the speaker enclosure 1 at an angle along the vertical direction. The woofer 2 and tweeter 3 are built into the speaker enclosure 1 and fixed side by side to the front fixing plate 4 at the front end of the speaker enclosure 1, with the tweeter 3 located above the woofer 2. In specific implementation, the sound field diffusion speaker of this utility model includes a mesh cover 8, which is detachably installed on the front fixing plate 4 at the front end of the speaker enclosure 1. By setting the mesh cover 8, damage to the tweeter 3 and woofer 2 caused by impact can be prevented, and dust accumulation on the tweeter 3 and woofer 2 can be avoided, reducing the workload of cleaning dust from the speaker. The sound field diffusion type speaker of this utility model also includes several anti-vibration feet 9, which are respectively installed at the four corners of the bottom of the speaker cabinet 1. In specific implementation, there are four anti-vibration feet 9 designed as cylindrical structures, which provide stable support and can dampen vibrations in the speaker. They can also buffer vibrations when the speaker cabinet vibrates, thus preventing sound reproduction distortion caused by the vibration of the speaker cabinet. This invention designs the speaker enclosure 1 as a trapezoidal structure, with the front fixing plate 4 fixed at an angle to the front end of the speaker enclosure 1. The woofer 2 and tweeter 3 are fixed side-by-side to the front fixing plate 4 at the front end of the speaker enclosure 1, so that the woofer 2 and tweeter 3 are arranged at an angle in the speaker enclosure 1. This makes the sound propagation angle larger, wider, and broader, providing a larger sound field effect in a larger space. It also allows for a larger and more balanced sound effect in a space, and can be used by users of different heights. Because different users have different heights and different ear heights, this design better meets the needs of different users' listening positions, adapts to a variety of different application scenarios, and improves the practicality of the speaker.

[0030] In this embodiment of the invention, the outer edge of the speaker enclosure 1, which is fixed to the front fixing plate 4, is provided with an arc structure 5. The outer edge of the speaker enclosure 1, which is fixed to the front fixing plate 4, is set as an arc structure 5. Traditional speaker structures use right-angled edges, which easily lead to diffraction interference of sound waves at sharp edges, resulting in uneven sound field distribution, concentrated reflection of high-frequency sound waves, affecting sound clarity, posing a safety hazard from impacts, and lacking a soft appearance. The arc-edged speaker enclosure 1 designed in this invention reduces sound wave diffraction, resulting in a better sound field effect. It also eliminates sharp edges, reducing the risk of user bumps and scratches, making the speaker suitable for homes and children's play areas, while also improving the speaker's aesthetics.

[0031] The inclination angle between the front fixing plate 4 and the bottom plate 11 of the speaker enclosure 1 in this invention ranges from 85° to 88°. In this embodiment, the inclination angle between the front fixing plate 4 and the bottom plate 11 of the speaker enclosure 1 is 85°.

[0032] In this embodiment of the utility model, the tweeter 3 is a 1x1 inch tweeter 3, and the woofer 2 is a 1x4 inch woofer 2. The front fixing plate 4 is provided with a first fixing groove 41 that cooperates with the tweeter 3 and a second fixing groove 42 that cooperates with the woofer 2. The tweeter 3 is installed in the first fixing groove 41, and the woofer 2 is installed in the second fixing groove 42. A tweeter protective frame 31 is fixed to the edge of the tweeter 3, and a woofer protective frame 21 is fixed to the edge of the woofer 2. The tweeter protective frame 31 is provided with a first fixing hole and a first fixing bolt 32 at the four corners, and the woofer protective frame 21 is provided with a second fixing hole and a second fixing bolt 22 at the four corners. The tweeter 3 is installed in the first fixing groove 41 of the front fixing plate 4 through the first fixing hole and the first fixing bolt 32, and the woofer 2 is installed in the second fixing groove 42 of the front fixing plate 4 through the second fixing hole and the second fixing bolt 22.

[0033] This invention relates to a sound field diffusion type speaker, which includes a bass reflex tube 6. The bass reflex tube 6 is installed inside the speaker enclosure 1, with its bottom end located on one side of the woofer 2. The bass reflex tube 6 is configured with a curved structure. Specifically, a bass reflex hole that mates with the bass reflex tube 6 is provided on the inner wall of the rear end of the speaker enclosure 1. The bass reflex hole is located on the rear panel of the speaker enclosure 1, and the opening at the top of the bass reflex tube 6 is installed at the bass reflex hole on the rear panel of the speaker enclosure 1. By setting up the bass reflex tube 6, the bass reflex of the woofer 2 is achieved, thereby enhancing the bass response. The curved structure is designed primarily to reduce the blowing noise from direct airflow and can also effectively enhance the air compression force, making the woofer 2 more powerful and giving the speaker a rich bass effect, thus enhancing the user experience.

[0034] In this embodiment of the invention, the sound field diffusion type speaker includes a crossover 7, a positive terminal 71, and a negative terminal 72. The crossover 7 is installed inside the speaker enclosure 1 and is distributed opposite to the subwoofer 2. One end of the positive terminal 71 and the negative terminal 72 are fixed to the crossover 7 at intervals, and the other end of the positive terminal 71 and the negative terminal 72 are used to connect to the power amplifier terminals. The crossover 7 is a 2-way crossover 7, which is connected to the power amplifier terminals through the positive terminal 71 and the negative terminal 72, thereby driving the crossover 7 to work.

[0035] like Figures 7-8 As shown, Figure 7 This is a sound field effect diagram of existing traditional audio equipment. Figure 8 This is a sound field effect diagram of the sound field diffusion type speaker of this utility model. Figure 7 and Figure 8 As shown in the schematic diagram of the sound field effect, traditional speakers are planar, and the sound diffuses forward, which limits the propagation of sound. In contrast, the sound field diffusion speaker of this invention has a trapezoidal structure for the speaker enclosure 1, and the front fixing plate 4 is fixed at the front end of the speaker enclosure 1 at an angle along the vertical direction. This allows the woofer 2 and tweeter 3 to have a certain tilt angle, so that the sound propagation angle of the woofer 2 and tweeter 3 is larger, wider and wider, which can provide a larger sound field effect in the space, so that a larger and more balanced sound effect can be obtained in the space.

[0036] The present invention has been described in detail above. The above description is only a preferred embodiment of the present invention and should not be construed as limiting the scope of the present invention. All equivalent changes and modifications made in accordance with the scope of this application should still fall within the scope of the present invention.
