Description

Technical Field

[0001] The utility model relates to the technical field of speaker equalizers, in particular to a speaker equalizer. Background Art

[0002] A speaker is a device that can convert audio signals into sound, and it plays an extremely important role in the sound system. The working principle of the speaker is to convert electrical energy into sound energy so that the sound can be amplified and transmitted.

[0003] Traditional speakers are relatively simple in design and structure, with a small projection area, and the sound is often scattered and uneven. As a result, when traditional speakers are used in a large space, the sound is easily diffused and dissipated, thereby reducing the effect of audio transmission, making the volume and sound quality heard by the audience at different locations different. This uneven diffusion not only reduces the effect of audio transmission, but also affects the audience's listening experience. Utility Model Content

[0027] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. The preferred embodiments of the present invention are given in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0028] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be an intermediate element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be an intermediate element at the same time.

[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0030] See also Figures 1 to 7 , is a speaker equalizer according to an embodiment of the present invention, comprising an equalizer body 10, and side wings 20 connected to opposite ends of the equalizer body 10; a sound outlet space 30 is formed between the two side wings 20 and the equalizer body 10. The side wings 20 are used to connect to a speaker box 41, ensuring that the speaker equalizer can be stably mounted on the speaker box 41. At this time, the speaker equalizer corresponds to the speaker 42 one by one.

[0031] The equalizer body 10 is roughly in the shape of a quadrangular pyramid, and is provided with a main body front 11 and a main body back 12; the main body front 11 is a plane, and the main body front 11 faces the outside; the main body back 12 is an inner concave surface, and the main body back 12 faces the speaker 42, which can better fit the speaker 42, reduce sound wave reflection, and improve sound quality. Among them, the orthographic projection area of ​​the main body front 11 is larger than the orthographic projection area of ​​the main body back 12, which can provide a larger forward projection area, which is conducive to the diffusion of sound waves and the improvement of directivity. Further, the center of the equalizer body 10 is located on the central axis of the speaker 42.

[0032] In this embodiment, two cavities 110 are formed on the equalizer body 10 corresponding to the front side 11 of the body, which are recessed inwards to improve the transmission and diffusion characteristics of sound waves.

[0033] A smooth main body side surface 13 is formed on the equalizer main body 10 corresponding to the main body front surface 11 and the main body back surface 12. The main body side surface 13 is used to smoothly connect the main body front surface 11 and the main body back surface 12. The main body side surface 13 faces the sound output space 30 to ensure that the sound waves can be smoothly and unimpededly propagated to the outside along the main body side surface 13, thereby improving the directivity of the speaker equalizer. In addition, the equalizer main body 10 is provided with smooth main body end surfaces 14 at the opposite ends facing the side wing 20, and the main body end surfaces 14 are used to smoothly connect the equalizer main body 10 and the side wing 20.

[0034] The side wing 20 includes a side wing base 21 and a docking seat 22 connected to the opposite ends of the side wing base 21; the docking seat 22 is used to abut the speaker box body 41. The speaker box body 41 is screwed onto the docking seat 22 with screws to ensure a stable connection between the speaker equalizer and the speaker box body 41.

[0035] A limiting surface 23 is provided on one side of the side wing base 21 close to the end surface 14 of the main body, and the opposite ends of the limiting surface 23 are respectively connected to the sound output space 30. An avoidance groove is formed between the limiting surface 23 and the end surface 14 of the main body, and the avoidance groove is used to correspond to the periphery of the speaker 42, so that the center of the circle of the back side 12 of the main body is located on the central axis of the speaker 42.

[0036] In this embodiment, in order to better fit the periphery of the speaker 42, the main body end surface 14 is configured as an arc-shaped convex surface, and the limiting surface 23 is configured as an arc-shaped concave surface.

[0037] In this embodiment, the center of the limiting surface 23 coincides with the center of the equalizer body 10 , ensuring that the center of the equalizer body 10 can be maintained on the central axis of the speaker 42 to further optimize the propagation effect of the sound wave.

[0038] The above-mentioned speaker equalizer has a simple structure and is easy to use. The equalizer body 10 is designed in a quadrangular pyramid shape, and the front face 11 of the body is flat and the orthographic projection area is larger than the back face 12 of the body, so that the sound waves can be diffused more evenly during the transmission process, thereby improving the transmission and diffusion characteristics of the sound waves. The sound outlet space 30 formed between the two side wings 20 and the equalizer body 10 further enhances the directivity and improves the sound quality effect.

[0039] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0040] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
