Description

Technical Field

[0001] The utility model relates to the technical field of loudspeakers, in particular to a sound box with a sound guide tube. Background Art

[0002] With the continuous development of communication equipment and the continuous improvement of people's consumption capacity, people have higher and higher requirements for the audio effects of electronic products. The music needs to be more beautiful and the vocals need to be clearer.

[0003] The speakers in the industry currently have the following shortcomings:

[0004] 1. The rear sound cavity is insufficient, and sound-absorbing cotton or even bass powder needs to be added to improve the low frequency, which will increase the cost;

[0005] 2. The speaker itself improves the low frequency, but it usually results in a loss of yield. Utility Model Content

[0006] The technical problem to be solved by the utility model is: in order to overcome the deficiencies in the prior art, a sound box with a sound guide tube is provided, and the vibration of the speaker is balanced by the sound guide tube to bring high-quality audio.

[0007] The utility model solves the technical problem by adopting a technical solution: a sound box with a sound guide tube, comprising a cavity shell and a speaker, wherein the cavity shell comprises an upper shell and a lower shell, and the upper shell and the lower shell are combined to form a cavity for placing the speaker.

[0008] A sound guide tube is also provided in the cavity, and the inner cavity of the sound guide tube forms a passage, a first opening of the passage is located on the cavity shell and communicated with the outside of the sound box, and a second opening of the passage is located on one side of the speaker and communicated with the speaker.

[0009] Furthermore, the sound guide tube is divided into two parts, the upper part of the sound guide tube and the upper shell are an integrated structure, and the lower part of the sound guide tube and the lower shell are an integrated structure.

[0010] After the upper shell and the lower shell are combined, the upper sound guide tube and the lower sound guide tube are combined to form a sound guide tube with a passage.

[0011] Furthermore, the sound guide tube has several corners in the cavity, and the sound guide tube at the corners has a chamfered structure. Through the design of the corners, the length of the sound guide tube is increased without occupying an area. The specific design of the passage can be carried out according to requirements.

[0012] Furthermore, the upper shell is provided with an opening for accommodating the speaker to pass through, and the upper end surface of the speaker does not exceed the opening.

[0013] The anti-phase sound waves radiated by the speaker's paper cone into the sound box's cavity shell, when passed through the cavity shell and then radiated outward through the sound guide tube, some of the lower-limit frequency sound waves can be close in phase with the same-frequency sound waves radiated from the front of the paper cone. This can enhance the radiation efficiency of the speaker's paper cone and thus expand the low-frequency response.

[0014] The beneficial effect of the utility model is that the sound box with the sound guide tube of the utility model improves the cavity shell so that the sound guide tube and the cavity shell are integrally formed, and the length of the sound guide tube is long, which enhances the heavy bass while ensuring that the bass can be cleaner, thus meeting the requirements of high performance.

[0015] By using this design with a sound guide tube, the vibration of the speaker can be better balanced, providing high-quality audio while ensuring smooth production. BRIEF DESCRIPTION OF THE DRAWINGS
