Abstract

The utility model provides a tweeter diffuser which comprises a dome tweeter and a horn diffuser, the dome tweeter comprises an annular panel and a tweeter unit, and the tweeter unit comprises a tweeter diaphragm extending out of the inner ring of the annular panel. The horn diffusion piece comprises a supporting plate fixedly connected to the top of the annular panel and a conical part arranged in the center of the bottom of the supporting plate, a spherical groove is formed in the bottom of the conical part, a conical diffusion opening is formed in the center of the supporting plate, and the high-pitch vibrating diaphragm and the spherical groove are arranged at intervals to form a vibration gap. When the tweeter unit works, part of sound waves generated by vibration of the tweeter diaphragm are compressed through the narrow opening of the conical diffusion opening to increase sound pressure, then the sound waves are diffused after passing through the conical diffusion opening, and part of the sound waves are spread and diffused between the conical part and the annular panel after passing through the vibration gap to form sound waves diffused to 360 degrees. The sound diffusion condition of a real musical instrument is simulated to the greatest extent, and the sound transmission angle range is more comprehensive.

Description

Technical Field

[0001] This utility model relates to the field of loudspeaker technology, and more particularly to a high-frequency loudspeaker diffuser. Background Technology

[0002] Tweeters are an important component of audio systems, used to produce high-frequency tones. Their function is to enable the audio system to accurately reproduce high-frequency audio signals, providing a more comprehensive and richer audio experience. However, existing tweeters do not have a comprehensive sound propagation angle, resulting in a significant difference in sound dispersion compared to the live sound of a real musical instrument, leading to less than ideal performance. Summary of the Invention

[0003] The problem to be solved by this invention is to provide a high-frequency loudspeaker diffuser that can better simulate the sound diffusion of a real musical instrument.

[0004] To solve the above-mentioned technical problems, a tweeter diffuser provided by this utility model is provided, comprising a dome tweeter and a horn diffuser. The dome tweeter includes an annular panel and a tweeter unit installed at the bottom of the annular panel. The tweeter unit includes a tweeter diaphragm extending from the inner ring of the annular panel. The horn diffuser includes a support plate fixedly connected to the top of the annular panel and a conical portion disposed at the bottom center of the support plate. A spherical groove is provided at the bottom of the conical portion. A conical diffuser opening communicating with the spherical groove is provided at the center of the support plate. The tweeter diaphragm and the spherical groove are spaced apart to form a vibration gap.

[0005] Preferably, countersunk holes are provided on all four sides of the support plate, and through holes corresponding to the countersunk holes are provided on the annular panel. Bolts are connected between the countersunk holes and the through holes, and spacers that abut against the support plate and the annular panel are fitted on the bolts.

[0006] The beneficial effects of this utility model are as follows: This utility model provides a tweeter diffuser. By installing a horn diffuser on the dome tweeter, when the tweeter unit is working, part of the sound waves generated by the vibration of the tweeter diaphragm are compressed at the narrow opening of the conical diffuser, resulting in an increase in sound pressure. After passing through the conical diffuser, the sound waves are diffused. Part of the sound waves propagate and diffuse between the cone and the annular panel after passing through the vibration gap, forming a sound wave that diffuses in 360°. This simulates the sound diffusion of a real musical instrument to the greatest extent, with a more comprehensive sound propagation angle range and better performance. Attached Figure Description

Detailed Implementation

[0013] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure.

[0014] Based on the embodiments described in this disclosure, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this disclosure.

[0015] refer to Figure 1-5 .

[0016] This utility model provides a tweeter diffuser, comprising a dome tweeter 1 and a horn diffuser 2. The dome tweeter 1 includes an annular panel 10 and a tweeter unit 11 installed at the bottom of the annular panel 10. The tweeter unit 11 includes a tweeter diaphragm 110 extending from the inner ring of the annular panel 10. The horn diffuser 2 includes a support plate 20 fixedly connected to the top of the annular panel 10 and a conical portion 21 disposed at the bottom center of the support plate 20. The bottom of the conical portion 21 is provided with a spherical groove 210. The center of the support plate 20 is provided with a conical diffuser opening 200 communicating with the spherical groove 210. The tweeter diaphragm 110 and the spherical groove 210 are spaced apart to form a vibration gap 211.

[0017] Its working principle is as follows: by installing a horn diffuser 2 on the dome tweeter 1, when the tweeter unit 11 is working, part of the sound wave generated by the vibration of the tweeter diaphragm 110 is compressed at the narrow opening of the conical diffuser 200, resulting in an increase in sound pressure. After passing through the conical diffuser 200, it is diffused. Part of the sound wave passes through the vibration gap 211 and propagates between the conical part 21 and the annular panel 10, forming a sound wave that diffuses in 360°. This simulates the sound diffusion of a real musical instrument to the greatest extent, with a more comprehensive range of sound propagation angles and better performance.

[0018] Based on the above embodiments, countersunk holes 201 are provided on all four sides of the support plate 20, and through holes 100 corresponding to the countersunk holes 201 are provided on the annular panel 10. Bolts 101 are connected between the countersunk holes 201 and the through holes 100. A spacer 102 is sleeved on the bolt 101 and abuts against the support plate 20 and the annular panel 10, which can realize the installation and positioning between the horn diffuser 2 and the dome tweeter 1, and ensure the gap distance between the tweeter diaphragm 110 and the spherical groove 210.

[0019] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made by those skilled in the art to the technical solutions of the present utility model without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
