Description

Technical Field

[0001] This utility model relates to the field of electronic equipment, and in particular to an audio device. Background Technology

[0002] Currently, audio equipment comes in various shapes and sizes. To accommodate these diverse forms, the internal cavity connected to the speaker serves as both the sound field cavity and the mounting cavity for electronic components. Some electronic components are exposed within the cavity, while others are housed in additional enclosures within it. Consequently, the internal space of the cavity is inevitably further divided and encroached upon, resulting in a more uneven sound field cavity with an increased number of right angles, making it difficult to guarantee an ideal sound field space. This poses significant challenges and difficulties for post-production sound tuning.

[0003] The technical problem to be solved by this application is: how to set up a more ideal audio sound field space in the cavity of a speaker. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a sound structure.

[0005] The technical solution adopted by this utility model is: an audio structure, including a sound transmission box, characterized in that the rear end of the sound transmission box is set as a funnel shape, the front end of the funnel shape is a larger end, and the front end of the sound transmission box is provided with at least one loudspeaker.

[0006] In some embodiments, the funnel shape is composed of several trapezoidal side panels and a rear end plate, with the rear end plate located at the rear end of the funnel shape.

[0007] In some implementations, the funnel shape is set as a hemispherical shape.

[0008] In some implementations, the speaker enclosure is an axisymmetric shape.

[0009] In some embodiments, the front end of the speaker enclosure is provided with a mounting hole, and the speaker is fixedly installed in the mounting hole, which is located at the end away from the funnel shape.

[0010] In some embodiments, a mounting cavity is included, which is disposed in the outer wall space of the funnel-shaped body.

[0011] The beneficial effects of this utility model are as follows:

[0012] This type of speaker structure, by setting a funnel-shaped cavity at the rear end of the speaker enclosure, can ensure that the speaker has a better sound field space, reduce the superposition and cancellation effects of sound waves and the standing wave effect, thus obtaining a smoother acoustic curve, improving the sound quality of the speaker, and also facilitating the subsequent speaker tuning.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] This utility model provides two technical solutions:

[0021] Example 1

[0022] Please see Figure 1 An acoustic structure includes a sound-transmitting enclosure 1 and a mounting cavity 3. The front end of the sound-transmitting enclosure 1 can be cylindrical or rectangular, and the rear end is funnel-shaped 2. In this embodiment, the front end of the sound-transmitting enclosure 1 is rectangular. The rectangular body and the funnel-shaped body 2 together form the main body of the acoustic cavity. The mounting cavity 3 is disposed in the outer wall space of the funnel-shaped body 2 at the rear end of the sound-transmitting enclosure 1. The funnel-shaped body 2 is funnel-shaped, with the end closer to the rectangular body being the larger end. The sound-transmitting enclosure 1 is an axisymmetric figure.

[0023] Please see Figures 1-3In this embodiment, the funnel-shaped body 2 is composed of several trapezoidal side panels and a rear end plate. The rear end plate is located at the far end of the funnel-shaped body 2 from the rectangular body, i.e., at the rear end of the funnel-shaped body 2. The rear end plate is fixedly connected to the trapezoidal side panels. In this embodiment, the overall shape of the speaker enclosure 1 is a front rectangular body and a rear funnel-shaped body 2. The number of trapezoidal side panels of the funnel-shaped body 2 and the dimensional relationship between them and the rear end plate can be adjusted according to the size of the electronic device 4 or the overall appearance of the speaker. The front end of the speaker enclosure 1 is provided with a mounting hole and a speaker 11. The speaker 11 is fixedly installed in the mounting hole, with the magnet end of the speaker 11 facing the funnel-shaped body 2. The mounting cavity 3 is fixedly installed on the outer wall space of the funnel-shaped body 2, which can cover the funnel-shaped body 2 in appearance, making the overall appearance more aesthetically pleasing. The mounting cavity 3 can be fixedly connected to the speaker enclosure 1 or detachably connected according to actual needs.

[0024] The working principle and usage of this utility model are as follows: Due to the axial symmetry of the speaker enclosure 1 and its smoother inner wall, and the absence of acute and right angles in the rear funnel-shaped portion 2, a more ideal audio sound field space is created. The superposition and cancellation effects of sound waves and the standing wave effect are reduced, thus achieving a smoother acoustic curve and laying a solid foundation for good sound quality. The mounting cavity 3 can be adjusted in size and customized in appearance according to customer needs. Please refer to... Figure 4 The comparative example is a speaker enclosure without a funnel-shaped part 2 at the rear end, while the embodiment has a funnel-shaped part 2 at the rear end. As can be seen from the figure, the frequency response curve of the embodiment is significantly smoother than that of the comparative example, and a smooth curve helps to improve the listening experience.

[0025] In this embodiment, the original single-shaped speaker enclosure is creatively transformed using a sheet metal structure to form a funnel-shaped body 2 at the rear end of the speaker enclosure 1 according to certain rules. The space where the speaker 11 is located is the speaker enclosure 1, which is the main body of the acoustic cavity for sound conduction and resonance. The sheet metal structure used for sealing and partitioning can be formed by combination or by molding to create an empty funnel-shaped body 2. The size of the mounting cavity 3 can be varied as needed by adjusting the connection position between the sealing and partitioning sheet metal structure and the inner wall of the enclosure, or by adjusting the dimensional relationship between the trapezoidal side panel and the rear panel of the funnel-shaped body 2. The sheet metal structure of the funnel-shaped body 2 is sealed and connected. The larger end of the funnel-shaped body 2 is sealed and fixed to the sheet metal around the inner wall of the speaker enclosure 1. The speaker 11 is mounted on the front panel of the speaker enclosure 1. The position of the vent is not fixed; here, we only take the example of it being located at the lower part of the front panel of the speaker enclosure 1 and on both sides of the speaker 11. The mounting cavity 3 can be easily made in different colors as needed, creating a variety of personalized color appearances with the speaker body.

[0026] Example 2

[0027] The difference from Example 1 is that, please refer to... Figure 5 The funnel-shaped object 2 is hemispherical in shape.

[0028] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
