Description

Technical Field

[0001] The utility model relates to the technical field of earphones, in particular to an earphone with a rotating head. Background Art

[0002] Headphones are an audio output device that provides private music enjoyment and clear phone calls. They come in a variety of styles, including in-ear and over-ear headphones. In-ear headphones are compact and portable, offering excellent sound isolation; over-ear headphones are comfortable and generally offer superior sound quality. Headphones allow you to immerse yourself in music in any environment, whether on a busy commute, in a quiet study space, or at the gym. High-quality headphones can accurately reproduce sound details and reveal rich musical layers. They also allow you to make calls anytime, anywhere, ensuring your voice is clearly transmitted. With the advancement of technology, wireless headphones are becoming increasingly popular, freeing you from the constraints of cables and making them more convenient to use. In short, headphones have become an indispensable part of our daily lives.

[0003] Existing in-ear headphones usually have a single earphone shape that can only be used for the left ear or the right ear, and the structure is fixed. When the earphone is worn on one ear for a long time, it cannot be switched to the other ear, which is inconvenient to use. Utility Model Content

[0004] In order to overcome the above technical problems, the utility model provides an earphone with a rotating head, which is used to improve the problem that a single earphone cannot match two earbands.

[0005] In order to achieve the above-mentioned purpose, the utility model proposes an earphone with a rotating head, comprising an earphone head with a generating unit installed inside, a plurality of spherical protrusions are provided on the outer edge of the circumferential side wall of the earphone head port, a sound guide cover is sleeved on the earphone head, and a spring piece abutting against the spherical protrusions is installed on the inner circumferential wall of the sound guide cover that contacts the earphone head.

[0006] Multiple spherical protrusions are provided on the earphone head, and springs are provided on the inner wall of the sound guide cover to abut against the spherical protrusions. This allows the sound guide cover to rotate around the earphone head and to be fixed in position after rotating a predetermined distance. When the springs come into contact with the spherical protrusions, the springs first transmit their elastic force to the spherical protrusions. When the spherical protrusions slide over the highest point of the springs, they quickly slide to the recessed part of the springs with the help of the springs' elastic force. The two adjacent springs clamp the spherical protrusions between them, preventing them from moving freely.

[0007] Correspondingly, the spring clips prevent the sound guide cover from rotating freely, controlling the sound guide cover in its rotated position and maintaining a stable state. When the sound guide cover needs to be adjusted again, the sound guide cover is rotated, driving the spring clips to slide over the spherical protrusions, causing the spherical protrusions to fall back into the angle between them and the spring clips, re-fixing them in a stable position.

[0008] Preferably, a receiving hole is formed on the earphone head, the spherical protrusion is a spherical abutment part, a spring is provided in the receiving hole, one end of the spring abuts against the receiving hole, and the other end abuts against the spherical abutment part.

[0009] A receiving hole is provided on the earphone head, and a spring is disposed within the receiving hole. The spring presses against the spherical abutment at the port, giving the spherical abutment an elastic force. When the spring sheet applies pressure to the spherical abutment, the spherical abutment presses downward on the spring, causing the spherical abutment to retract into the receiving hole, facilitating the sliding of the spring sheet. When the spring sheet slides over the highest point of the protrusion, the spherical abutment is pushed out by the spring and falls into the angle between the two spring sheets, thereby positioning the sound guide cover.

[0010] Preferably, the surface of the spherical abutment member is covered with a metal layer.

[0011] Covering the outside of the spherical abutment with a metal layer can reduce the external friction of the spherical abutment and increase the service life of the spherical abutment.

[0012] Preferably, the surface of the elastic sheet is covered with a silicone layer.

[0013] Covering the outside of the shrapnel with a silicone layer can reduce the wear between the spherical abutment part of the metal outer layer and the shrapnel, and will not make excessive noise when rotating.

[0014] Preferably, an elastic ball is provided between the spring sheet and the inner peripheral wall of the sound guide cover.

[0015] An elastic ball is arranged between the shrapnel and the inner wall of the sound guide cover to assist the shrapnel in returning to its original shape after being squeezed, thereby preventing the shrapnel from bending excessively and sticking back to the inner wall of the sound guide cover.

[0016] Preferably, a limiting column with a protruding structure is formed on the edge of the sound guide cover port.

[0017] The purpose of setting the limit column is to limit the rotation angle of the sound guide cover, so as to accurately locate the position to which the sound guide cover should be rotated for the user.

[0018] Preferably, a slide rail is formed on the edge of the sound guide cover port, and the limiting column is arranged in the slide rail and is slidably connected to the slide rail.

[0019] A slide rail is set on the edge of the port of the sound guide cover, and a limit column is installed therein. The position of the limit column can be adjusted manually, thereby providing users with more adjustment options.

[0020] Preferably, a rubber pad is provided in the slide rail for clamping the limiting column from both sides of the limiting column.

[0021] The purpose of setting the rubber pad is to limit the movement of the limit column. When the limit column is set to a good position, it will not easily move away from the set position, thereby ensuring the accuracy of the sound guide cover during rotation.

[0022] The earphones with a rotating head provided by the utility model can rotate the sound guide cover according to the required angle by means of multiple spherical protrusions arranged on the earphone head and the spring pieces arranged on the sound guide cover, so as to adapt to the form that can be used by both ears. By rotating the sound guide cover, a single earphone can achieve a deformed structure that can be used by both ears. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The following describes embodiments of the present invention with reference to the accompanying drawings. Elements and features described in one drawing or one embodiment of the present invention may be combined with elements and features shown in one or more other drawings or embodiments. It should be noted that for the sake of clarity, the drawings and descriptions omit the representation and description of components or processes that are not relevant to the present invention and are known to those of ordinary skill in the art.

[0028] The present invention will be further described below in conjunction with the accompanying drawings.

[0029] like Figure 1 、 Figure 2 As shown, the earphones with a rotating head provided by the utility model include an earphone head 1 with a generating unit installed inside, a plurality of spherical protrusions 2 are provided on the outer edge of the circumferential side wall of the port of the earphone head 1, a sound guide cover 3 is sleeved on the earphone head 1, and a spring piece 4 that abuts against the spherical protrusions 2 is installed on the inner circumferential wall of the sound guide cover 3 that contacts the earphone head 1.

[0030] Multiple spherical protrusions 2 are provided on the earphone head 1, and springs 4 are provided on the inner circumference of the sound guide cover 3 to abut against the spherical protrusions 2. This allows the sound guide cover 3 to rotate around the earphone head 1 and to be fixed in position after rotating a predetermined distance. When the springs 4 come into contact with the spherical protrusions 2, the springs 4 first transmit their elastic force to the spherical protrusions 2. When the spherical protrusion 2 slides over the highest point of the springs 4, it quickly slides to the recessed part of the springs 4 with the help of the springs 4's elastic force. The two adjacent springs 4 sandwich the spherical protrusions 2, preventing them from moving freely.

[0031] Accordingly, the spring clip 4 restricts the free rotation of the sound guide cover 3, controlling the sound guide cover 3 in the rotated position and maintaining a stable state. When the angle of the sound guide cover 3 needs to be adjusted again, the sound guide cover 3 is rotated, driving the spring clip 4 to slide over the spherical protrusion, so that the spherical protrusion falls back into the angle position relative to the spring clip 4, and is fixed to a stable position again.

[0032] In one embodiment of the present invention, a receiving hole 5 is formed on the earphone head 1, the spherical protrusion 2 is a spherical abutment member, and a spring 6 is provided in the receiving hole 5. One end of the spring 6 abuts against the receiving hole 5, and the other end abuts against the spherical abutment member.

[0033] A receiving hole 5 is provided on the earphone head 1, and a spring 6 is disposed within the receiving hole 5. The spring 6 presses against the spherical abutment at the port position, imparting an elastic force to the spherical abutment. When the spring 4 applies pressure to the spherical abutment, the spherical abutment presses downward against the spring 6, causing the spherical abutment to retract into the receiving hole 5, facilitating the sliding of the spring 4. When the spring 4 slides over the highest point of the protrusion, the spherical abutment is pushed out by the spring 6 and falls into the angle between the two springs 4, thereby positioning the sound guide cover 3.

[0034] In one embodiment of the present invention, the surface of the spherical abutment member is covered with a metal layer.

[0035] Covering the outside of the spherical abutment with a metal layer can reduce the external friction of the spherical abutment and increase the service life of the spherical abutment.

[0036] In one embodiment of the present invention, the surface of the elastic piece 4 is covered with a silicone layer.

[0037] Covering the outer portion of the spring piece 4 with a silicone layer can reduce the wear between the spherical abutment member of the metal outer layer and the spring piece 4 and prevent excessive noise from being emitted during rotation.

[0038] In one embodiment of the present invention, an elastic ball 7 is provided between the spring piece 4 and the inner peripheral wall of the sound guide cover 3 .

[0039] An elastic ball 7 is arranged between the spring piece 4 and the inner wall of the sound guide cover 3 to assist the spring piece 4 in returning to its original shape after being squeezed, thereby preventing the spring piece 4 from bending excessively and sticking to the inner wall of the sound guide cover 3 in reverse.

[0040] In one embodiment of the present invention, a limiting column 8 with a protruding structure is formed on the edge of the port of the sound guide cover 3.

[0041] The purpose of providing the limiting column 8 is to limit the rotation angle of the sound guide cover 3, so as to accurately locate the position to which the sound guide cover 3 should be rotated for the user.

[0042] In one embodiment of the present invention, a slide rail 9 is formed on the edge of the port of the sound guide cover 3 , and the limiting column 8 is arranged in the slide rail 9 and is slidably connected to the slide rail 9 .

[0043] A slide rail 9 is provided on the edge of the port of the sound guide cover 3, and a limit column 8 is installed therein. The position of the limit column 8 can be adjusted manually, thereby providing the user with more adjustment options.

[0044] In one embodiment of the present invention, a rubber pad is provided in the slide rail 9 to clamp the limiting column 8 from both sides.

[0045] The purpose of setting the rubber pad is to limit the movement of the limit column 8. When the limit column 8 is set to a position, it will not easily move away from the set position, thereby ensuring the accuracy of the sound guide cover 3 during rotation.

[0046] The earphones with a rotating head provided by the present invention can rotate the sound guide cover 3 according to the required angle by means of multiple spherical protrusions 2 provided on the earphone head 1 and the spring pieces 4 provided on the sound guide cover 3, so as to be suitable for a form that can be used by both ears. By rotating the sound guide cover 3, a single earphone can achieve a deformed structure that can be used by both ears.
