Description

Technical Field

[0001] The utility model relates to the technical field of oxygen chamber waveguides, and specifically relates to a sound waveguide group for an oxygen chamber. Background Art

[0002] An oxygen chamber is a device that provides a micro-high-pressure oxygen environment. With the help of the oxygen chamber environment, music therapy is introduced. While patients receive hyperbaric oxygen therapy in the oxygen chamber, they listen to specific music through headphones or speakers to achieve the effects of physical and mental relaxation and stress reduction. This treatment method aims to promote physical rehabilitation and improve mental health through the dual effects of oxygen and music. When the existing speakers are used in an oxygen chamber, due to the narrow space, the sound separation becomes extremely poor, and the recognition of the left and right channels is lost. In this way, the sound quality heard by the human ear is poor, directly affecting the sound therapy effect of the oxygen chamber. Moreover, during the operation of the oxygen chamber, it is a pressure-changing environment, which also limits the application of headphones. Summary of the Utility Model

Through the set high-frequency waveguide structure and low-frequency waveguide structure, they are distributed on the top of the oxygen chamber, and the opening directions are all towards the wide-side side walls of the rectangular mounting plate at the top of the oxygen chamber. In this way, when there is sound transmission, the sound is conducted to both sides respectively through the distributed two groups of sound waveguide groups, and the sound is reflected back by the side walls of the oxygen chamber. In this way, the sound is conducted directionally, reducing the looseness of the sound, improving the separation of the channel sounds, creating a sense of three-dimensional sound for listening, enabling the user to hear the music more clearly, and improving the sound therapy effect.

When describing the embodiments of the present utility model in detail, for the convenience of explanation, the cross-sectional views showing the device structure will be enlarged locally out of the general proportion, and the schematic diagrams are only examples and should not limit the scope of protection of the present utility model herein. In addition, in actual production, three-dimensional spatial dimensions including length, width, and depth should be included.

[0025] To make the purpose, technical solutions, and advantages of the present utility model clearer, the following will further describe the embodiments of the present utility model in conjunction with the drawings.

[0026] The utility model provides a sound waveguide group for an oxygen chamber. Through the arranged high - frequency waveguide structure and low - frequency waveguide structure, they are distributed on the top of the oxygen chamber, and the opening directions are all towards the wide - side side walls of the rectangular mounting plate at the top of the oxygen chamber. In this way, when there is sound transmission, the sound is conducted to both sides through the two distributed sound waveguide groups respectively, and the sound is reflected back by the side walls of the oxygen chamber. In this way, the sound is conducted directionally, reducing the looseness of the sound, improving the separation degree of the sound in the sound channel, creating a three - dimensional sense of sound listening, enabling the user to hear the music more clearly and improving the sound therapy effect.

[0027] Figures 1 - 3 Shown is a schematic diagram of the overall structure of an embodiment of a sound waveguide group for an oxygen chamber according to the utility model. Please refer to Figures 1 - 3 This embodiment mainly includes: a high - frequency waveguide structure 1 and a low - frequency waveguide structure 2.

[0028] Note that for the convenience of explanation, Figure 3 only two side walls of the oxygen chamber facing the waveguide opening direction are shown. In reality, the front and rear walls also exist, and the entrance and exit of the oxygen chamber can be located on any of the front and rear walls. When a person is in the oxygen chamber, they can take a lying position, and in Figure 3 this case, the head and feet of the person should face the front and rear walls that are not shown.

[0029] The high - frequency waveguide structure 1 includes a first high - frequency waveguide sheet 11 arranged, a high - frequency hemispherical shielding cover 12 fixed at the middle position of the first high - frequency waveguide sheet 11, and a high - frequency opening 13 opened on the side of the high - frequency hemispherical shielding cover 12;

[0030] The high - frequency waveguide structure 1 further includes a second high - frequency waveguide sheet 14 fixed on the arc surface of the high - frequency hemispherical shielding cover 12 and a high - frequency sound - guiding sheet 15 fixed on the top surface of the second high - frequency waveguide sheet 14;

[0031] The low - frequency waveguide structure 2 includes a first low - frequency waveguide sheet 21 arranged, a low - frequency hemispherical shielding cover 22 fixed at the middle position of the first low - frequency waveguide sheet 21, and a low - frequency opening 23 opened on the side of the low - frequency hemispherical shielding cover 22;

[0032] The low - frequency waveguide structure 2 further includes a second low - frequency waveguide sheet 24 fixed on the arc surface of the low - frequency hemispherical shielding cover 22 and a low - frequency sound - guiding sheet 25 fixed on the top surface of the low - frequency hemispherical shielding cover 22;

[0033] Among them, the opening directions of the high - frequency opening 13 and the low - frequency opening 23 are towards the wide - side side walls of the rectangular mounting plate;

[0034] During specific use, the high-frequency waveguide structure 1 and the low-frequency waveguide structure 2 form a set of sound waveguide groups. Inside each oxygen chamber, two sets of sound waveguide groups are provided at the top of the oxygen chamber. The high-frequency waveguide structure 1 is distributed inside the oxygen chamber, and the low-frequency waveguide structure 2 is distributed outside the oxygen chamber. The high-frequency openings 13 and the low-frequency openings 23 in each sound waveguide group are oriented towards the wide-side sidewalls of the rectangular mounting plate. In this way, when sound is emitted, the sound passes through the two sets of sound waveguide groups, diffusing the sound to both sides of the oxygen chamber. Then, the sound is reflected by the oxygen chamber wall, thereby adjusting the diffusion direction of the sound, improving the sound separation, bringing a stereophonic sound reception feeling to the user's ears, and avoiding the problem that when the speaker diffuses sound in a narrow space, the sound diffuses everywhere, resulting in a poor listening effect and affecting the sound therapy effect.

[0035] Furthermore, through the provided reinforcing ribs 17, the hemispherical shielding cover is prevented from being suspended, and the hemispherical shielding cover is supported to prevent the problem of the hemispherical shielding cover collapsing and affecting normal sound conduction.

[0036] Specifically, the high-frequency waveguide structure 1 further includes a base 16 provided on the bottom surface of the first high-frequency waveguide sheet 11 and a reinforcing rib 17 that supports the high-frequency hemispherical shielding cover 12; the low-frequency waveguide structure 2 has a base 16 and a reinforcing rib 17 with the same structure.

[0037] During specific use, the base 16 is used to lock onto the surface of the rectangular mounting plate at the top of the oxygen chamber, and the reinforcing ribs 17 respectively support the corresponding high-frequency hemispherical shielding cover 12 and the low-frequency hemispherical shielding cover 22, avoiding suspension and collapse, and improving the stability of the entire waveguide group during use.

[0038] Although the present utility model has been described above with reference to the embodiments, various improvements can be made to it and components can be replaced with equivalents without departing from the scope of the present utility model. In particular, as long as there is no structural conflict, the various features in the disclosed embodiments of the present utility model can be combined with each other in any way. The exhaustive description of these combinations is not given in this specification only for the sake of saving space and resources.
