Apparently, the described embodiments are some but not all of the embodiments of the present disclosure. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts fall within the scope of protection of the present utility model.

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present utility model belongs. The terms used in the specification of the present utility model herein are only for the purpose of describing specific embodiments and are not intended to limit the present utility model. Specific Embodiment

[0033] As Figures 1 - 5 shown, this embodiment provides a sound structure (100) of an air handling device, including a speaker (110), a rear sound cavity housing (140) disposed on the back of the speaker (110), and a sound guiding cavity housing (120) disposed on the front of the speaker (110). The sound guiding cavity housing (120) is provided with a sound guiding hole (121) on the side away from the speaker (110), and a sound output cavity housing (130) is provided on the side of the sound guiding cavity housing (120) close to the sound guiding hole (121). The sound output cavity housing (130) is provided with a sound output hole (131) on the side away from the sound guiding hole (121). The rear sound cavity housing (140), the sound guiding cavity housing (120), and the sound output cavity housing (130) are coaxially arranged.

[0034] In this embodiment, a structural design of coaxially stacking the sound guiding cavity housing (120) and the sound output cavity housing (130) is adopted to achieve double amplification of audio. Specifically, the audio signal emitted by the speaker (110) is first amplified by the sound guiding cavity housing (120), then enters the sound output cavity housing (130) through the sound guiding hole (121), and after being amplified again by the sound output cavity housing (130), it is emitted through the sound output hole (131), realizing an increase in volume so that the user can hear clear voice.

[0035] In a more optimal embodiment, the speaker (110) is provided with a fixing member on the side facing the sound guiding cavity housing (120) to fix the speaker (110) to the open end of the sound guiding cavity housing (120). Specifically, the fixing member can be adhesive tape to paste and fix the speaker (110) to the inner side wall of the sound guiding cavity housing (120).

[0036] In a more optimal embodiment, the sound guiding cavity housing (120) is sleeved on the open end of the sound output cavity housing (130), and the longitudinal cross-sectional area of the sound output cavity housing (130) is larger than that of the sound guiding cavity housing (120) to further amplify the audio emitted by the sound guiding cavity housing (120).

[0037] In a more optimal embodiment, the sound guiding holes (121) are evenly distributed on one side of the sound guiding cavity housing (120); the sound output holes (131) are evenly distributed on one side of the sound output cavity housing (130) to ensure that the audio signals emitted through the sound guiding holes (121) and the sound output holes (131) are more uniform and clear.

[0038] In a more optimal embodiment, both the sound guiding hole (121) and the sound output hole (131) are oblong through holes. Specifically, in this embodiment, oblong through holes are adopted. Compared with conventional circular through holes, the sound guiding cavity housing (120) has a larger sound guiding area, and the sound output cavity housing (130) has a larger sound output area, so that the amplified voice is clearer.

[0039] In a more optimal embodiment, side ears (122) extend from the side circumference of the sound guiding cavity housing (120), and the side ears (122) are provided with fixing holes (1221). Screws pass through the fixing holes (1221) to fix the sound guiding cavity housing (120) to the body (220) of the air treatment device. Preferably, the side ears (122) are located on one side of the open end of the sound guiding cavity housing (120), and the open end of the sound guiding cavity housing (120) is fixed to the body (220) by means of screw fixation, thereby limiting the speaker (110) between the body (220) and the sound guiding cavity housing (120) to prevent the fixing member of the speaker (110) from loosening and causing the speaker (110) to fall off.

[0040] In a more preferred embodiment, a wire groove (123) is provided on the side circumference of the sound guiding cavity housing (120) to pass through the electrical wires connecting the speaker (110).

[0041] In a more preferred embodiment, a fan housing (210) is provided inside the air handling device, and the sound output cavity housing (130) and the fan housing (210) are integrally formed. In this embodiment, the integral formation of the sound output cavity housing (130) and the fan housing (210) not only increases the stability of the sound structure (100), but also eliminates the need for fasteners and simplifies the installation.

[0042] In a more preferred embodiment, the rear sound cavity housing (140) includes an inner housing (141) and an outer housing (142) that are concentrically arranged. The inner housing (141) abuts against the back surface of the speaker (110), and the outer housing (142) abuts against the sound guiding cavity housing (120). In this embodiment, the concentrically arranged inner housing (141), outer housing (142) and the back surface of the speaker (110) form two closed rear sound cavities, making the sound emitted by the speaker (110) more mellow.

[0043] In a more preferred embodiment, the rear sound cavity housing (140) and the body (220) of the air handling device are integrally formed.

[0044] The above are only the specific embodiments of the present invention, enabling those skilled in the art to understand or implement the present disclosure. Various modifications to these embodiments will be obvious to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to these embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
