Description

Technical Field

[0001] This invention relates to the field of headphone design, and in particular to a headphone sound enhancement cavity channel structure. Background Technology

[0002] Headphones are a common and widely used audio playback device, often used for music enjoyment, monitoring, or gaming. Audio playback quality is a crucial indicator of headphone quality, and improvements in audio playback now largely rely on upgrades to the speakers within the headphones.

[0003] In actual design, it was found that, in addition to the speaker itself, the speaker needs to be fixed by the shell of the headphones, and the sound quality of the speaker is greatly affected by the structure of the shell. However, the speaker and shell design of current headphones is relatively simple. The shell structure is the bottleneck that limits the sound quality of headphones, and there are basically no ways to improve the sound quality of headphones by changing the shell structure. Summary of the Invention

[0004] The purpose of this invention is to provide a cavity channel structure for enhancing the sound effect of headphones, which can solve one or more of the above-mentioned problems.

[0005] According to one aspect of the present invention, a sound enhancement cavity channel structure for headphones is provided, comprising a speaker, a cavity cover, a speaker cover, a first mesh fabric, a second mesh fabric, and a third mesh fabric. The cavity cover and the horn cover are connected and enclose a receiving cavity, in which the horn is embedded. The cavity cover is provided with a bass channel that communicates with the accommodating cavity, and the bass channel has a first opening that communicates with the outside. The first mesh fabric is attached to the cavity cover and covers the first opening. The speaker cover is provided with a tweeter channel and a vent hole that communicate with the accommodating cavity. The tweeter channel has a second opening that communicates with the outside, and the vent hole is located at a third opening that communicates with the outside. The second mesh and the third mesh are respectively connected to the horn cover, the second mesh covers the second opening, and the third mesh covers the third opening.

[0006] The beneficial effects of this invention are as follows: By setting vent holes and a third mesh fabric on the vent holes, the air permeability of the accommodating cavity can be adjusted by controlling the air permeability of the vent holes through the third mesh fabric, thereby improving the stability of the speaker sound source. Moreover, the third mesh fabric can prevent foreign objects from entering the accommodating cavity through the third opening. A bass channel is also provided, which can serve as the path for air to enter and exit the rear cavity of the accommodating cavity, thereby enhancing the bass response and solving the problem of muffled sound. A treble channel is also provided, which can serve as the path for air to enter and exit the front cavity of the accommodating cavity, thereby enhancing the treble surround sound. Furthermore, a first mesh fabric and a second mesh fabric are respectively provided on the treble channel and the second mesh fabric, which can be used to control the airflow of the bass channel and the treble channel, thereby adjusting the bass and treble effects to obtain better sound quality. At the same time, it can also prevent foreign objects from entering the accommodating cavity through the first opening or the second opening.

[0007] In some embodiments, the invention further includes a permeable bubble wrap attached to the horn cover and covering a second and a third mesh fabric. The permeable bubble wrap prevents foreign objects from entering the accommodating cavity and damaging the horn, and also serves a decorative purpose.

[0008] In some embodiments, the horn cover has several fixing holes that communicate with the receiving cavity, and the bubble wrap covers these fixing holes. The fixing holes ensure that a certain amount of air can enter and exit the receiving cavity.

[0009] In some embodiments, the present invention further includes a sealing sheet, wherein the speaker cover has a protrusion within the accommodating cavity, the sealing sheet is connected to the protrusion, and the tweeter channel is disposed within the space enclosed by the protrusion and the sealing sheet. Compared to directly molding the tweeter channel integrally onto the speaker cover, this method of setting the tweeter channel is less difficult to manufacture.

[0010] In some embodiments, the invention further includes a sealing ring, wherein the cavity cover has a groove, the sealing ring is embedded in the groove, and abuts against the horn cover. The sealing ring improves the sealing performance of the connection between the cavity cover and the horn cover.

[0011] In some embodiments, the cavity cover has a first groove around the first opening, and the first mesh fabric is embedded in the first groove. The first groove can facilitate quick and easy positioning of the first mesh fabric and limit its movement to ensure that the first mesh fabric effectively covers the first opening.

[0012] In some embodiments, the horn cover has a second groove around the second opening, and the second mesh fabric is embedded in the second groove. The second groove can facilitate quick and easy positioning of the second mesh fabric and limit its movement to ensure that the second mesh fabric effectively covers the second opening.

[0013] In some embodiments, the horn cover has a third groove around the third opening, and the third mesh fabric is embedded in the third groove. The third groove can facilitate quick and easy positioning of the third mesh fabric and limit its movement to ensure that the third mesh fabric can effectively cover the third opening.

[0014] In some implementations, the bass channel is located on one side of the speaker, and the treble channel and vent are located on the other side of the speaker. Attached Figure Description
