[0018] The present utility model will be described in more detail below with reference to the drawings and embodiments.

[0019] The present utility model discloses a low-frequency adjustable OWS earphone. As shown in Figures 1 to 5 , it includes a main earphone housing 1. A loudspeaker 2 is arranged in the main earphone housing 1. A long strip-shaped sliding groove 10 is opened on the main earphone housing 1. An air vent hole 11 is opened at the bottom of the sliding groove 10. The air vent hole 11 is communicated with the back-side space of the loudspeaker 2. The air vent hole 11 extends along the length direction of the sliding groove 10. A sliding cover 12 is arranged in the sliding groove 10. The sliding cover 12 can slide along the sliding groove 10. The sliding cover 12 is used to cover part or all of the air vent holes 11.

[0020] In the above structure, a sliding cover 12 is slidably provided in the slide groove 10, and an air leakage hole 11 is opened at the bottom of the slide groove 10, and the air leakage hole 11 is connected to the back space of the speaker 2, and the sliding cover 12 can slide along the slide groove 10 and is used to cover part or all of the air leakage hole 11. When adjusting the position of the sliding cover 12, the opening size of the air leakage hole 11 can be controlled, thereby adjusting the exhaust volume of the rear cavity of the speaker. The change of the exhaust volume will affect the sound quality of the earphone, especially in controlling the resonance peak of the earphone. The appropriate exhaust volume can optimize the frequency response curve of the earphone, so that the performance of music at different frequencies is more balanced and natural, especially when the exhaust volume increases, the bass volume intensity becomes smaller, and when the exhaust volume decreases, the bass volume intensity becomes larger. Based on the above structure, the utility model can realize manual adjustment of the low-frequency sound quality effect, and at the same time, the structure is simple, no design software is required, and the design and manufacturing costs are low.

[0021] For the main structure of the earphone main housing 1, please refer to Figure 4 and Figure 5 The earphone main housing 1 is provided with a sound hole 3, and the sound hole 3 is aligned with the sound-emitting side of the speaker 2.

[0022] In order to prevent the slide groove 10 from being directly exposed to the outside, in this embodiment, the air leakage hole 11 faces the side of the speaker 2. That is, the opening direction of the air leakage hole 11 is nearly perpendicular to the opening direction of the sound hole 3.

[0023] As a preferred embodiment, a tuning net 4 is provided in the earphone main housing 1, and the tuning net 4 covers the air leakage hole 11. The tuning net 4 with a preset thickness and a preset mesh density can prevent dust and have a certain sound quality adjustment effect.

[0024] In order to facilitate the sliding cover 12, in this embodiment, Figures 1 to 3 As shown, the outer surface of the sliding cover 12 is formed with protruding ridges 13 .

[0025] See also Figure 5 In this embodiment, a sealing cover 5 is fixed inside the earphone main housing 1, and the sealing cover 5 is covered on the back side of the speaker 2, and there is a gap 6 between the sealing cover 5 and the speaker 2. In the above structure, this embodiment preferably uses the sealing cover 5 to seal the back space of the speaker 2, and the airflow in the back space of the speaker 2 can only be discharged through the air leakage hole 11. Under this condition, when the position of the sliding cover 12 is adjusted, the sound quality can be adjusted more obviously with the change of the air leakage hole 11. In practical applications, in order to better cover the speaker 2 and form the gap 6 with it, in this embodiment, the sealing cover 5 is preferably a structure that bulges outward.

[0026] In practical applications, this embodiment adopts an independent subwoofer tuning structure. By sliding the sliding cover back and forth, the size change of the air vent can be simply achieved without the need for professional tools or complex operations. When in use, users can select the subwoofer level suitable for their own listening experience according to their personal preferences to achieve personalized sound quality adjustment. Through appropriate adjustment, the utility model can meet the requirements of different environments and music types, such as various scenarios like concerts, studio monitoring, or daily commuting.

[0027] Furthermore, this embodiment includes a battery pack 7, and an earhook 8 is connected between the battery pack 7 and the main headphone housing 1.

[0028] Compared with the prior art, the utility model sets an independent rear cavity for the speaker in the traditional headphone rear cover, sets an air vent in the independent rear cavity, pastes a tuning net on the air vent, and sets a sliding cover outside the air vent. The size of the air vent is controlled by sliding the sliding cover, thereby controlling the exhaust volume of the independent rear cavity. The change in the exhaust volume will affect the headphone sound quality. Especially in controlling the resonance peak of the headphone, an appropriate exhaust volume can optimize the frequency response curve of the headphone, making the performance of music at different frequencies more balanced and natural. When the exhaust volume increases, the low volume will become weaker and the intensity will become smaller, and the mid-high frequencies will become brighter accordingly; when the exhaust volume decreases, the low volume will become more and the intensity will become larger, and the mid-high frequencies will weaken accordingly. Users can simply adjust the position of the sliding cover according to their needs to meet their own requirements for the headphone bass and achieve corresponding sound quality adjustment.

[0029] The above description is only a preferred embodiment of the utility model and does not limit the utility model. Any modifications, equivalent replacements, or improvements made within the technical scope of the utility model shall be included within the scope protected by the utility model.
