Description

Technical Field

[0001] This utility model relates to the field of headphone technology, and in particular to a noise-canceling headphone. Background Technology

[0002] Headphones are sophisticated audio playback devices. Their core function is to convert received electronic audio signals into sound wave vibrations, which are then transmitted to the ear through earplugs or earcups to reproduce sound. Headphones are commonly used in mobile phones, portable music players, radios, portable game consoles, and digital audio players.

[0003] Most existing headphones have an integrated structure design. For example, there is a noise-canceling headphone with the existing patent publication number CN221553411U. Because existing headphones are difficult to adjust, dust easily accumulates on the surface of the headphones when they are not in use. This not only affects the use of the headphones, but also makes it easy for dust to cause infection when it enters the ear. Therefore, we provide a noise-canceling headphone. Utility Model Content

[0004] To address the problem in the aforementioned background technology where headphones are difficult to adjust and thus prone to dust accumulation when not in use, this invention provides a noise-canceling headphone.

[0005] This utility model is achieved by the following technical solution: a noise-canceling headphone, comprising two sets of shells and an adjustment component, wherein a hanging ring is fixedly connected between the two sets of shells, and the headphone body is movably disposed inside the shell.

[0006] The adjustment assembly includes two sets of rotating shafts fixedly connected to the top and bottom of the earphone body and rotatably connected to the housing. A knob is fixedly connected to the bottom end of the lower rotating shaft coaxially. A circular seat is fixedly connected to the top of the earphone body and the upper rotating shaft extends into the interior of the circular seat. A pin is slidably connected to the circular seat, and a spring is sleeved on the outside of the pin. A pin hole is opened on the upper rotating shaft.

[0007] As a further improvement to the above solution, an arc-shaped limiting groove is provided on the top of the annular seat, and a limiting block is fixedly connected to the outside of the upper rotating shaft, and the limiting block is slidably connected to the arc-shaped limiting groove.

[0008] As a further improvement to the above solution, the angle of the arc-shaped limiting groove is 180°.

[0009] As a further improvement to the above solution, the two ends of the spring are respectively fixedly connected to the end protrusion of the pin and the annular seat.

[0010] As a further improvement to the above solution, the size of the pin hole matches the size of the pin rod and the pin hole passes through the upper rotating shaft.

[0011] As a further improvement to the above solution, the diameter of the earphone body is smaller than the inner diameter of the shell, and a rubber retaining ring is fixedly connected to the gap between the earphone body and the shell.

[0012] As a further improvement to the above solution, a sound-insulating cotton ring is fixedly connected to the outside of the earphone body.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model allows the headphone body to rotate 180° by rotating the knob and sliding between the limiting block and the arc-shaped limiting groove. At this time, the side of the headphone body that plays sound will flip into the interior of the shell, thus preventing dust from falling into the headphone when it is placed. It is highly practical.

[0015] 2. This utility model allows for easy rotation and adjustment of the earphone body by pulling the pin rod to disengage it from the pin hole. At this time, the spring will be stretched. After rotation and adjustment, the pin rod is released, and under the spring's own rebound, the pin rod will automatically insert into the pin hole, thereby positioning the adjusted earphone body and further improving the practicality of the device.

[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0024] Example 1:

[0025] Please combine Figure 1-5 This embodiment of a noise-canceling headphone includes two sets of shells 1, with a hanging ring 2 fixedly connected between the two sets of shells 1. The headphone body 3 is movably disposed inside the shell 1, and a sound-insulating cotton ring 5 is fixedly connected to the outside of the headphone body 3. The sound-insulating cotton ring 5 can play a noise-canceling role, thereby enhancing the sound quality of the headphone playback.

[0026] An adjustment assembly for adjusting the headphone body 3 includes two sets of rotating shafts 101 fixedly connected to the top and bottom of the headphone body 3, and the rotating shafts 101 are rotatably connected to the housing 1. A knob 102 is coaxially fixedly connected to the bottom end of the lower rotating shaft 101. A circular seat 103 is fixedly connected to the top of the headphone body 3, and the upper rotating shaft 101 extends into the interior of the circular seat 103. A pin 104 is slidably connected to the circular seat 103, and a spring 105 is sleeved on the outside of the pin 104. The two ends of the spring 105 are respectively connected to the pin. The end protrusion of 104 is fixedly connected to the ring seat 103. The upper rotating shaft 101 is provided with a pin hole 106. The top of the ring seat 103 is provided with an arc-shaped limiting groove 107. The upper rotating shaft 101 is fixedly connected to a limiting block 108, and the limiting block 108 is slidably connected to the arc-shaped limiting groove 107. The angle of the arc-shaped limiting groove 107 is 180°, which can control the maximum rotation angle of the earphone body 3. The size of the pin hole 106 matches the size of the pin rod 104, and the pin hole 106 passes through the upper rotating shaft 101.

[0027] The implementation principle of a noise-canceling headphone in this embodiment is as follows: When the headphone is placed after use, first pull the pin 104 to disengage it from the pin hole 106. At this time, the spring 105 will be stretched. Then, rotate the knob 102. Utilizing the sliding cooperation between the limiting block 108 and the arc-shaped limiting groove 107, the headphone body 3 can be rotated 180°. At this time, the side of the headphone body 3 that plays sound will flip into the interior of the housing 1, thereby preventing dust from settling on the headphone. Then, release the pin 104. Under the rebound action of the spring 105, the pin 104 will automatically re-insert into the pin hole 106, thereby positioning the adjusted headphone body 3. Finally, repeat the above operation to adjust the other headphone body 3. Conversely, the side of the headphone body 3 that plays sound can be flipped to the outside of the housing 1 for easy use.

[0028] Example 2:

[0029] This embodiment is an improvement on embodiment 1, in that: the diameter of the earphone body 3 is smaller than the inner diameter of the shell 1, and a rubber retaining ring 4 is fixedly connected to the gap between the earphone body 3 and the shell 1. Since the diameter of the earphone body 3 is smaller than the inner diameter of the shell 1, the earphone body 3 will not be obstructed when it is rotated. The retaining ring 4 can play the role of blocking dust, preventing dust from entering the interior of the shell 1 through the gap. In addition, the retaining ring 4 is made of rubber, which makes it highly elastic. Therefore, the retaining ring 4 will not affect the rotation of the earphone body 3 while blocking dust.

[0030] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
