DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] It should be noted that the terms "first", "second", etc. in the present invention are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present disclosure described herein can be implemented in an order other than those illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure.

[0030] See also Figures 1 to 10 In an embodiment of the utility model, a novel wall-mounted sound amplifying speaker comprises a speaker body 1; a first inclined plate 2 and a second inclined plate 3 are symmetrically arranged at the front end of the speaker body 1; and the first inclined plate 2 is inclined toward the left front, and the second inclined plate 3 is inclined toward the right front; a first speaker group and a second speaker group are arranged inside the speaker body 1, facing the first inclined plate 2 and the second inclined plate 3; so that the first speaker group and the second speaker group can emit sound in both directions to the lower left and the lower right respectively.

[0031] Specifically, the front end of the speaker body 1 adopts a symmetrical design and is respectively equipped with a first inclined plate 2 and a second inclined plate 3, so that the overall appearance is more balanced; the first inclined plate 2 is inclined toward the left front, and the second inclined plate 3 is inclined toward the right front, which can optimize the propagation direction of the sound and make it more reasonably dispersed to the left and right sides; the first speaker group and the second speaker group are arranged inside the speaker body 1 facing the first inclined plate 2 and the second inclined plate 3, which can ensure that the audio signal is more effectively propagated to the surrounding space through the inclined plates; because the first speaker group and the second speaker group are respectively facing the lower left and lower right, the speaker can achieve two-way sound, expand the sound coverage, and allow the audience to feel the audio effect more comprehensively.

[0032] Furthermore, the speaker body 1 includes a rear panel 4, a left panel 5 and a right panel 6 arranged on both sides of the rear panel 4; and the first inclined panel 2 and the second inclined panel 3 are arranged in front of the rear panel 4, and are respectively connected to the left panel 5 and the right panel 6; and the top and bottom of the rear panel 4 are respectively provided with a top panel 7 and a bottom panel 8 to seal it.

[0033] Specifically, the speaker body 1 includes a back panel 4, a left side panel 5, a right side panel 6, a first inclined panel 2 and a second inclined panel 3, which form the basic frame of the entire speaker; the first inclined panel 2 and the second inclined panel 3 are respectively located in front of the back panel 4, and are connected to the left side panel 5 and the right side panel 6, ensuring the firm fixation of the inclined panels and making the overall structure more balanced; the top and bottom of the back panel 4 are respectively provided with a top panel 7 and a bottom panel 8, which are used to seal the back panel 4, help prevent audio signal leakage, and improve the acoustic performance of the speaker.

[0034] Furthermore, when viewing the speaker body 1 from the top, the angle between the central axis of the first speaker group or the central axis of the second speaker group and the back panel 4 is sixty-five degrees; and the angle between the first inclined plate 2 or the second inclined plate 3 and the back panel 4 is twenty-five degrees; and when viewing the speaker body 1 from the left side or the right side, the angle between the central axis of the first speaker group or the central axis of the second speaker group and the back panel 4 is sixty-nine point five degrees.

[0035] Specifically, viewed from the top, the angle between the central axis of the first speaker group or the central axis of the second speaker group and the back panel 4 is sixty-five degrees, which means that the sound emission direction of the speaker group is tilted to a certain extent relative to the vertical axis, which helps to better cover the audience area and meet the clear listening needs of students in the corners of the first and last rows of the classroom. The sound amplification of the speakers reaches this position directly; the angle between the first inclined plate 2 or the second inclined plate 3 and the back panel 4 is twenty-five degrees, which can affect the refraction and diffusion of sound to improve the sound field performance of the speakers; viewed from the left or right side: the angle between the central axis of the first speaker group or the central axis of the second speaker group and the back panel 4 is sixty-nine 1.5 degrees. From a side perspective, the sound emission direction of the speaker group is more inclined relative to the vertical axis to better meet the sound needs of the audience position. In actual classrooms, there are usually beams and large glass windows to form sound reflection surfaces, which can easily lead to acoustic defects such as echoes and standing waves. Therefore, the installation height of the speaker should not be too high, and the angle should be tilted towards the students. When the speaker is installed in the classroom, the central axis of the speaker should face the student in the middle of the classroom, and the front of the speaker should be tilted to the ground, forming an angle of 20.5° with the wall. The speaker should avoid transmitting sound directly to the glass, as glass reflection will cause the treble to scatter and lose three-dimensional sense. The angle between the inclined surface and the wall should be no less than 20.5°.

[0036] Furthermore, a through hole 9 is formed on the left side plate 5 or the right side plate 6 ; and a reflex tube 10 for adjusting low-frequency sound effects is arranged in the through hole 9 .

[0037] Specifically, the left side panel 5 or the right side panel 6 is formed with a through hole 9, which helps to improve the airflow inside the speaker and affect the propagation and adjustment of the low-frequency sound effects; a bass reflex tube 10 for adjusting the low-frequency sound effects is arranged in the through hole 9; the bass reflex tube 10 is a device for adjusting the audio phase and frequency response, and is used to adjust the low-frequency sound effects. The bass reflex tube 10 can be adjusted by changing the length of the bass reflex tube 10; the bass reflex tube 10 of different lengths can be replaced to achieve the desired sound effect.

[0038] Furthermore, an iron mesh 11 is provided at the front end of the speaker body 1 to protect the first speaker group and the second speaker group; and the iron mesh 11 covers the first inclined plate 2, the second inclined plate 3, the left side plate 5, and the right side plate 6; and the two ends of the iron mesh 11 are fixed to the left side plate 5 and the right side plate 6 by screws respectively.

[0039] Specifically, the front end of the speaker body 1 is protected by an iron mesh 11 to ensure that the first speaker group and the second speaker group are protected from collision or damage by external objects; the iron mesh 11 covers the first inclined plate 2, the second inclined plate 3, the left plate 5 and the right plate 6, which can not only effectively protect the speaker group, but also protect the various structural parts of the speaker, making it more durable; the two ends of the iron mesh 11 are fixed to the left plate 5 and the right plate 6 by screws to ensure that the iron mesh 11 fits tightly to the front end of the speaker, and it is also convenient for users to disassemble and maintain it when necessary.

[0040] Furthermore, a plurality of wall-mounted brackets 12 mounted on the wall are installed on the rear side of the rear panel 4; and the wall-mounted brackets 12 are fixed to the rear panel 4 by screws; and the wall-mounted brackets 12 are all formed with wall-mounted holes; and the rear panel 4 is also formed with a groove inwardly; and a junction box 13 is provided in the groove.

[0041] Specifically, a plurality of wall-mounted brackets 12 are installed on the rear side of the rear panel 4 for fixing the speaker to the wall, so that the user can choose to hang the speaker on the wall, thereby better adapting to different space layouts; the wall-mounted brackets 12 are fixed to the rear panel 4 by screws, ensuring a firm connection of the wall-mounted brackets 12 and providing a stable installation; the wall-mounted brackets 12 are formed with wall-mounted holes, allowing the user to use appropriate screws or other fixing devices to install the speaker on the wall;

[0042] The rear plate 4 is formed with a groove inwardly, and a junction box 13 is arranged in the groove. The positive and negative terminals of the junction box 13 are used to input audio signals.

[0043] Furthermore, the first inclined plate 2 and the second inclined plate 3 are both formed with large speaker holes 14 and small speaker holes 15 distributed up and down; and the large speaker hole 14 is located above the small speaker hole 15; and the first speaker group and the second speaker group both include a large speaker 16 and a small speaker 17; and the large speaker 16 and the small speaker 17 are installed with the corresponding large speaker hole 14 and small speaker hole 15.

[0044] Specifically, the first inclined plate 2 and the second inclined plate 3 are both formed with speaker holes for installing speaker units. The first speaker group and the second speaker group both include a large speaker 16 and a small speaker 17, with both large speaker holes and small speaker holes. The large speaker hole 14 is located above the small speaker hole 15, which helps to form a more uniform sound field distribution and make the audio output more balanced. A more comprehensive audio performance can be achieved. The large speaker 16 is usually responsible for low and medium frequencies, while the small speaker 17 is responsible for high frequencies. The large speaker 16 and the small speaker 17 are installed in matching relationship with the corresponding large speaker hole 14 and the small speaker hole 15, ensuring the correct installation of the speaker unit and helping to optimize the acoustic performance of the speaker box.

[0045] Furthermore, the size of the large speaker 16 is 5.25 inches, and the size of the small speaker 17 is 3 inches.

[0046] Specifically, the size of the large speaker 16 is 5.25 inches, which indicates the diameter of the speaker. The large speaker 16 is relatively large and is better at processing audio signals in the low and mid-frequency ranges. The size of the small speaker 17 is 3 inches. The relatively small size is suitable for processing audio signals in the high-frequency range. The small speaker 17 is more outstanding in providing clear treble and mid-high frequencies.

[0047] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention.
