Description

Technical Field

[0001] This utility model relates to the field of audio equipment technology, specifically to a dual-ring waveguide horn speaker. Background Technology

[0002] Currently, in the field of audio equipment technology, two-way speakers are arranged vertically, with the front and rear distances of the two speaker units in the same plane. However, this arrangement can easily cause a significant phase difference between the high and low frequencies of the speaker.

[0003] At the same time, because the sound waves emitted by the speaker and the received sound waves are in the same direction, the direction of sound wave propagation cannot be changed. This results in the speaker being positioned relatively centrally. If the speaker is moved away by a small distance, the listening experience will be affected. Therefore, the speaker needs to be pointed at the listener's location when in use, which makes the existing two-way speakers have certain limitations. Utility Model Content

[0004] This invention was developed to solve the above-mentioned problems, and its purpose is to provide a double-ring waveguide horn speaker.

[0005] This utility model provides a dual-ring waveguide horn speaker, characterized by the following features:

[0006] Speaker housing,

[0007] The bass assembly includes a bass speaker and a bass waveguide horn. The bass speaker is mounted on the speaker enclosure, and the bass waveguide horn, which is horn-shaped, is mounted on the bass speaker and located at the end of the bass speaker that is outside the speaker enclosure.

[0008] The tweeter assembly includes a tweeter and a tweeter waveguide horn. The tweeter is mounted on the speaker enclosure and is located on the same outer wall of the enclosure as the woofer. The tweeter waveguide horn is horn-shaped and is mounted on the tweeter, located at the end of the tweeter that is outside the speaker enclosure.

[0009] The bass waveguide horn and the treble waveguide horn are arranged on the speaker enclosure in an alternating superposition manner.

[0010] The dual-ring waveguide horn speaker provided by this utility model also has the following feature: a crossover is provided inside the speaker housing. The crossover is used to separate the audio signal according to the high and low frequencies and send it to the woofer and tweeter respectively.

[0011] Functions and effects of utility models

[0012] According to the dual-ring waveguide horn speaker of this invention, because the bass waveguide horn and tweeter waveguide horn are arranged in an alternating superposition on the speaker housing, the vertical propagation direction of the treble is compressed by the bass, causing the treble propagation direction to spread laterally. This results in a wider lateral diffusion of the treble, thereby increasing the listening position of the speaker and improving the user's listening experience. Simultaneously, it can also compensate for the unnatural sound when using crossover speakers, thus improving the practical effect of this invention in use. Attached Figure Description

[0019] To make the technical means, creative features, objectives and effects of this utility model easy to understand, the following embodiments are described in detail with reference to the accompanying drawings.

[0020] Example

[0021] Figure 1 This is a structural schematic diagram of the present invention. Figure 2 This is a front view of the present invention. Figure 3 This is a side view of the present invention. Figure 4 This is a partial structural schematic diagram of the present invention.

[0022] like Figures 1 to 4 As shown, this embodiment provides a dual-ring waveguide horn speaker, including: a speaker housing 10, a bass component 20, a tweeter component 30, and a crossover 40.

[0023] like Figures 1 to 4 As shown, the speaker housing 10 is a hollow rectangular block. In this embodiment, the speaker housing 10 is the same as the speaker housing in the prior art, and its outer wall may be provided with functional openings such as device connection ports and air vents.

[0024] like Figures 1 to 4 As shown, the bass assembly 20 includes a bass speaker 21 and a bass waveguide horn 22, with the bass speaker 21 extending through the speaker enclosure 10. The bass waveguide horn 22 is horn-shaped, thus having at least one inner wall with a horn-shaped curved surface. The bass waveguide horn 22 is disposed on the bass speaker 21 and located at the end of the bass speaker 21 that is outside the speaker enclosure 10, with one end of the bass waveguide horn 22 abutting against the outer wall of the speaker enclosure 10.

[0025] like Figures 1 to 4 As shown, the tweeter assembly 30 includes a tweeter 31 and a tweeter waveguide horn 32. The tweeter 31 is mounted on the speaker enclosure 10, and the tweeter 31 and the woofer 21 are located on the same outer wall of the speaker enclosure 10. The tweeter waveguide horn 32 is horn-shaped and is located on the tweeter 31, at the end of the tweeter 31 that is outside the speaker enclosure 10. One end of the tweeter waveguide horn 32 is also in contact with the outer wall of the speaker enclosure 10. The horn-shaped design of the tweeter waveguide horn 32 ensures that it has at least one horn-shaped curved inner wall.

[0026] In this embodiment, the woofer 21 and tweeter 31 are preferably composed of a magnetic guide plate column, a magnet, a magnetic guide upper plate, a voice coil, a frame, a paper cone, and a dust cover. The woofer 21 and tweeter 31 in this invention can have the same structure as woofers and tweeters in the prior art, thereby facilitating the manufacturing of this invention and ensuring its feasibility.

[0027] In this embodiment, since a bass waveguide horn 22 and a tweeter horn 32 are respectively installed in front of the bass speaker 21 and the tweeter 31, it is beneficial to the diffusion of sound, thereby increasing the listening position of the speaker of this utility model.

[0028] In this embodiment, the bass waveguide horn 22 and the tweeter waveguide horn 32 are arranged in an alternating superposition on the speaker housing 10. Specifically, the bass waveguide horn 22 is located directly above the tweeter waveguide horn 32, and the height of the bass waveguide horn 22 is greater than that of the tweeter waveguide horn 32. Furthermore, the bottom end of the bass waveguide horn 22 is tangent to the top end of the tweeter waveguide horn 32. Therefore, it can perform a quadratic reflection of the treble, while compressing the vertical propagation direction of the treble in this speaker by the bass, thereby causing the treble propagation direction to spread laterally. This results in a wider lateral diffusion of the treble and a more natural transition between the bass and treble in this speaker.

[0029] like Figures 1 to 4As shown, the speaker housing 10 is also equipped with a crossover 40, which is used to separate the audio signal according to the frequency and send it to the woofer 21 and the tweeter 31 respectively.

[0030] In this embodiment, the frequency divider 40 can be the same as the frequency divider in the prior art, that is, as long as it can separate the audio signal according to the high and low frequencies and send it to the woofer 21 and the tweeter 31 respectively.

[0031] The role and effect of the embodiments

[0032] According to the dual-ring waveguide horn speaker of this invention, because the bass waveguide horn and tweeter waveguide horn are arranged in an alternating superposition on the speaker housing, the vertical propagation direction of the treble is compressed by the bass, causing the treble propagation direction to spread laterally. This results in a wider lateral diffusion of the treble, thereby increasing the listening position of the speaker and improving the user's listening experience. Simultaneously, it can also compensate for the unnatural sound when using crossover speakers, thus improving the practical effect of this invention in use.

[0033] The above embodiments are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model.
