Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of sound - emitting horns, and more specifically, it relates to a medium - high - frequency and ultra - high - frequency integrated horn. Background Art
[0002] The principle of a horn loudspeaker is that the diaphragm pushes the air at the bottom of the horn to work. Because the acoustic resistance is very large, the efficiency is very high. High - efficiency horn loudspeakers are mainly applied to the field of professional sound reinforcement. Traditional high - frequency horns and medium - frequency horns are generally installed separately, which makes the distance between the acoustic center points of the medium - frequency and high - frequency far, resulting in low directivity of the sound field.
[0003] The intermediate frequency described in this product refers to the frequency range of 200 - 500 Hz; the medium - high frequency refers to the frequency range of 500 - 6000 Hz; the high frequency refers to the frequency range of 6000 - 12000 Hz; and the ultra - high frequency refers to the frequency range of 12000 - 24000 Hz.
[0004] Currently, various types of speakers still mainly adopt a two - way frequency division with a bass speaker plus a horn tweeter. There are also ways to add a mid - range speaker to make a three - way frequency division. However, the mid - range unit generally uses a 4 - to 8 - inch mid - frequency speaker with a paper cone and cloth edge. There is generally a phenomenon that the sensitivity of the medium - high - frequency speaker is low and the medium - high - frequency energy is insufficient. Although some speakers use multiple 4 - to 8 - inch paper cone speakers as the mid - range and expand the sound in a three - way frequency division, with sufficient mid - frequency energy, there are still deficiencies in the medium - high - frequency and ultra - high - frequency, which negatively affects the projection ability of the medium - high - frequency sound waves of the speaker. Therefore, there is still room for improvement. Content of the Utility Model

[0026] The present utility model will be described in detail below with reference to the accompanying drawings and embodiments.
[0027] Embodiment 1
[0028] This embodiment provides a medium-high frequency integrated horn, as Figures 1-5 shown, including: a sound output frame body 1, a first sound guide tube 2 for conducting medium-high frequency sounds, and a second sound guide tube 3 for conducting high-frequency and ultra-high frequency sounds; one end of the first sound guide tube 2 is fixed on the sound output frame body 1, and the other end gradually narrows to form a first inner sound outlet hole 4; one end of the second sound guide tube 3 is fixed on the sound output frame body 1, and the other end gradually narrows to form a second inner sound outlet hole 5; a first edge seat 6 for installing a medium-high frequency drive head speaker 8 is arranged at the edge of the first inner sound outlet hole 4; one or two second edge seats 7 for installing high-frequency and ultra-high frequency drive head speakers 9 are arranged at the edge of the second inner sound outlet hole 5.
[0029] In practical applications, the medium-high frequency drive head speaker 8 is installed on the first edge seat 6 by bolts; the high-frequency and ultra-high frequency drive head speaker 9 is installed on the second edge seat 7 by bolts. At this time, the sound emitted by the medium-high frequency drive head speaker 8 is led out through the first sound guide tube 2, and the sound emitted by the high-frequency and ultra-high frequency drive head speaker 9 is led out through the second sound guide tube 3. Since both the first sound guide tube 2 and the second sound guide tube 3 are installed on the sound output frame body 1, the sound waves emitted by the medium-high frequency drive head speaker 8 and the high-frequency and ultra-high frequency drive head speaker 9 can be coupled and diffused under the action of the first sound guide tube 2 and the second sound guide tube 3; and during installation, the integrated horn can be installed at any position on the speaker panel, enhancing the medium-frequency, high-frequency and ultra-high frequency energy, so as to achieve a sound effect with stronger clarity and farther sound projection.
[0030] Further, the first sound guide tube 2 includes: a first side surface 21, a second side surface 22, a third side surface 23, and a fourth side surface 24. The first side surface 21, the second side surface 22, the third side surface 23, and the fourth side surface 24 enclose to form a first sound guide tube 4. The first side surface 21 is the opposite side surface of the third side surface 23, and the second side surface 22 is the opposite side surface of the fourth side surface 24.
[0031] In practical applications, the sound waves emitted by the mid-high frequency drive head speaker 8 are reflected and diffused through the first side surface 21, the second side surface 22, the third side surface 23, and the fourth side surface 24, and a more uniform directivity can be obtained within the coverage range.
[0032] Optionally, the diffusion angle between the first side surface 21 and the third side surface 23 is 3 to 45 degrees, the diffusion angle between the second side surface 22 and the fourth side surface 24 is 45 to 160 degrees, and the inner diffusion aperture of the first sound guide tube 4 is 20 to 210 mm.
[0033] Specifically, the shape of the first sound guide tube 2 is similar to an oval shape, which can gather and superimpose the sound waves emitted by the mid-high frequency drive head speaker 8, making the sound waves have a wider coverage range and a more uniform directivity within the coverage range.
[0034] Optionally, the second sound guide tube 3 includes: a first curved surface 31, a second curved surface 32, a third curved surface 33, and a fourth curved surface 34; the first curved surface 31, the second curved surface 32, the third curved surface 33, and the fourth curved surface 34 enclose to form a second sound guide tube 5; the first curved surface 31 is the opposite side surface of the third curved surface 33, and the second curved surface 32 is the opposite side surface of the fourth curved surface 34.
[0035] Specifically, the sound waves emitted by the mid-high frequency drive head speaker 8 are reflected and diffused through the first curved surface 31, the second curved surface 32, the third curved surface 33, and the fourth curved surface 34, and a more uniform directivity can be obtained within the coverage range.
[0036] Among them, the first curved surface 31, the second curved surface 32, the third curved surface 33, and the fourth curved surface 34 can form a high-frequency and ultra-high-frequency sound outlet. This high-frequency and ultra-high-frequency sound outlet shares the horn frame 1 with the mid-high frequency sound outlet formed by the first side surface 21, the second side surface 22, the third side surface 23, and the fourth side surface 24, so that the phase coupling of the mid-high frequency and the high-frequency and ultra-high frequency is better, expanding the working bandwidth of the mid-high frequency and high-frequency and ultra-high frequency, and making the sound waves at the crossover frequency points of the mid-frequency, high-frequency, and ultra-high frequency of the speaker tightly coupled at the overlap connection.
[0037] Optionally, the diffusion angle between the first curved surface 31 and the third curved surface 33 is 3 to 45 degrees; the diffusion angle between the second curved surface 32 and the fourth curved surface 34 is 45 to 160 degrees; the inner diffusion aperture diameter of the second sound guide tube 5 is 13 to 75 mm.
[0038] A medium-high frequency integrated horn of this embodiment enables the sound waves emitted by the medium-high frequency driver head speaker 8 and the high-frequency and ultra-high frequency driver head speaker 9 to be coupled and diffused through the first sound guiding tube 2 and the second sound guiding tube 5, making the medium-high frequency and ultra-high frequency energy of the speaker more sufficient and advantageous, enabling the kinetic energy of the sound waves of the speaker to be more fully diffused forward, with stronger penetration, and enabling the sound waves of the speaker to be coupled, focused, and transmitted farther.
