Description

Technical Field

[0001] The invention relates to the design of earphones, and in particular to a high and low pitch adjustment structure of earphones. Background Art

[0002] Whether resting, commuting or exercising, many people like to listen to music. Nowadays, music playback often requires the use of headphones, which have the advantages of being small in size and easy to carry.

[0003] The structure of common headphones is fixed after they are manufactured, and the structure of the headphones directly affects the treble and bass effects of sound playback. However, people's sound preferences are often different. Some people like the sound to be sharper, while others prefer the sound to be deeper. The fixed structure of headphones makes it difficult for people to effectively adjust the treble and bass effects of the sound to meet their personal preferences, resulting in poor flexibility. Summary of the Invention

[0004] The object of the present invention is to provide a headphone treble and bass adjustment structure that can solve one or more of the above problems.

[0005] According to one aspect of the present invention, there is provided a headphone treble and bass adjustment structure, comprising a shell and a rotating cover, wherein the rotating cover is rotatably mounted on the shell, the shell being provided with a accommodating cavity and a groove, the groove being provided with a first hole, the first hole being communicated with the accommodating cavity, the rotating cover being provided with a second hole and a recess, the second hole being communicated with the recess, a block being provided in the recess, the block being arranged in the groove, the block being able to block the first hole, and the amount of blocking of the first hole can be changed as the rotating cover rotates.

[0006] The beneficial effects of the present invention are as follows: the accommodating cavity of the present invention can be used to load the headphone speaker, and when the block does not block the first hole, a portion of the sound emitted by the headphone speaker in the accommodating cavity can be transmitted sequentially through the first hole, the recess, and the second hole. Moreover, since the present invention provides a block on the rotating cover, the position of the block can be changed by rotating the rotating cover, thereby changing the amount of blockage of the first hole by the block, that is, changing the degree of connection between the first hole and the recess, so as to adjust the high and low pitch effects of the sound transmitted from the second hole. In addition, the provision of the groove can limit the block and guide the movement of the block to a certain extent, thereby improving the reliability of the block. Therefore, the present invention can be applied to headphones and facilitates people to adjust the high and low pitch effects of the sound transmitted from the headphones to meet people's different preferences, and has high flexibility.

[0007] In some embodiments, the housing is provided with a limiting groove, the recess is provided with a limiting block, and the limiting block is movably disposed within the limiting groove. The limiting groove can limit the rotational range of the rotating cover, thereby avoiding limiting the movable position of the stopper, thereby ensuring that each change in the position of the stopper effectively changes the amount of obstruction of the first hole.

[0008] In some embodiments, there are multiple limiting grooves and multiple limiting blocks, and the multiple limiting blocks are movably arranged in the multiple limiting grooves in a one-to-one correspondence.

[0009] In some embodiments, the housing is provided with a protrusion, the protrusion being disposed within a recess, and the limiting groove being disposed on the protrusion. The protrusion being disposed within the recess can limit the rotational cover to a certain extent, thereby limiting the rotational cover to rotational motion as much as possible, thereby improving the reliability of the rotational cover on the housing.

[0010] In some embodiments, the shell includes a front shell and a rear shell, the front shell and the rear shell are connected, the accommodating cavity is surrounded by the front shell and the rear shell, and the groove and the first hole are both provided on the front shell.

[0011] In some embodiments, the front housing is provided with a plurality of latching blocks, and the rear housing is provided with a plurality of latching positions, wherein the plurality of latching blocks are latched in the plurality of latching positions in a one-to-one correspondence. The provision of the latching blocks and the latching positions can increase the contact area between the front housing and the rear housing, thereby improving the connection reliability between them.

[0012] In some embodiments, the front housing is provided with a sound outlet body, the sound outlet body having a main sound outlet hole, the main sound outlet hole being connected to the accommodating cavity. The sound outlet body facilitates the outflow of sound from the headphone speaker disposed in the accommodating cavity to ensure sufficient volume.

[0013] In some embodiments, the rotating cover is provided with a third hole, and the sound-emitting body is provided with a bump. The sound-emitting body passes through the third hole, and the sidewall of the third hole abuts against the bump. The bump not only serves as a mounting position for the rotating cover on the housing, but also effectively increases the contact area between the housing and the rotating cover, thereby improving the reliability of the connection between them.

[0014] In some embodiments, a protrusion is provided on the sidewall of the groove, and the protrusion is capable of abutting against the stopper. The provision of the protrusion can position the stopper, so that when the rotating cover is not rotating, the position of the stopper can be restricted by the protrusion and remain unchanged, thereby maintaining its current blocking amount of the first hole.

DETAILED DESCRIPTION

[0022] The present invention will be further described in detail below with reference to the accompanying drawings.

[0023] refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6 The earphone treble and bass adjustment structure of the present invention includes a shell 1 and a rotating cover 2.

[0024] The housing 1 includes a front housing 11 and a rear housing 12. The front housing 11 is provided with a latch 111, which may be multiple. In this embodiment, there are preferably two latches 111. The rear housing 12 is provided with a latch position 121, which may be multiple and the same number as the latches 111. In this embodiment, there are also preferably two latch positions 121. The two latches 111 are correspondingly latched in the two latch positions 121, thereby fixing the front housing 11 and the rear housing 12 together. In addition, the back of the rear housing 12 is also connected to a rear cover plate via bolts.

[0025] The front housing 11 and the rear housing 12 can enclose a receiving cavity 13. The bottom of the rear housing 12 can also be provided with a wire hole, which is connected to the receiving cavity 13. The front housing 11 of the housing 1 is provided with a protrusion 112, and the side of the protrusion 112 is provided with a limiting groove 113. There can be multiple limiting grooves 113. In this embodiment, there are preferably two limiting grooves 113.

[0026] A sound outlet body 114 is provided at the top center of the protrusion 112 of the front shell 11. The sound outlet body 114 is provided with a main sound outlet hole 1141. One end of the main sound outlet hole 1141 is connected to the accommodating cavity 13, and the other end of the main sound outlet hole 1141 can be connected to the atmosphere. A protrusion 1142 is also provided on the side of the sound outlet body 114.

[0027] A groove 115 is further defined on the protrusion 112 of the front housing 11 . A first hole 116 is defined in the groove 115 . The first hole 116 is communicated with the accommodating cavity 13 .

[0028] A recess 21 is provided at the bottom of the rotating cover 2 , and a second hole 22 is provided at the top of the rotating cover 2 . One end of the second hole 22 is connected to the recess 21 .

[0029] A third hole 23 is further defined in the middle of the rotating cover 2 . One end of the sound output body 114 passes through the third hole 23 , and the sidewall of the third hole 23 abuts against the protrusion 1142 of the sound output body 14 .

[0030] A limit block 211 is provided on the side wall of the recess 21. There may also be multiple limit blocks 211, and the number thereof may be equivalent to the number of the limit grooves 113. In this embodiment, there are preferably two limit blocks 211. The two limit blocks 211 are movably disposed in the two limit grooves 113, and the protrusion 112 is located in the recess 21, so that the rotating cover 2 is installed on the front shell 11 of the shell 1, and the rotating cover 2 can rotate on the front shell 11, and the limit grooves 113 can effectively limit the rotatable range of the rotating cover 2.

[0031] The other end of the second hole 22 on the rotating cover 2 after installation can be connected to the atmosphere, and a stopper 212 is further provided in the recess 21. The stopper 212 is located in the groove 115, and the stopper 212 can block the first hole 116. When the stopper 212 does not completely block the first hole 116, the first hole 116 can be connected to the recess 21, and as the rotating cover 2 rotates, the stopper 212 can move along the groove 115, that is, the stopper 212 can change its position in the groove 115 to change the amount of blocking of the first hole 116 by the stopper 212. In addition, a protrusion 117 is provided on the side wall of the groove 115. There may be multiple protrusions 117. In the present embodiment, there are preferably two protrusions 117. The protrusion 117 can abut against the stopper 212, thereby positioning the stopper 212, so that when the rotating cover 2 is not rotating, the position of the stopper 212 can be restricted by the protrusion 117 and will not change, so as to maintain the current blocking amount of the stopper 212 on the first hole 116 and reduce the erroneous movement of the stopper 212.

[0032] The earphone treble and bass adjustment structure of the present invention can be used in earphones. When in use, the earphone speaker can be fixedly set in the accommodating cavity 13, and an earphone silicone sleeve can be fixed on the sound-emitting body 114. Then, when the earphone speaker makes a sound, when the block 212 completely blocks the first hole 116, the sound basically only comes out from the main sound-emitting hole 1141, which is the sound that can be produced by the earphone using the earphone treble and bass adjustment structure.

[0033] When the block 212 does not completely block the first hole 116, part of the sound emitted by the earphone speaker can be transmitted through the main sound hole 1141, and part of the sound can be transmitted to the recess 21 through the first hole 116. The sound transmitted into the recess 21 can also be transmitted through the second hole 22. The sound transmitted can be superimposed with the sound transmitted from the main sound hole 1141, which is the sound that can be emitted by the earphone using the treble and bass adjustment structure of the earphone.

[0034] When the user feels that the treble and bass effects of the sound produced by the earphones using the treble and bass adjustment structure of the present earphones are not ideal, the user can rotate the rotating cover 2, and the stopper 212 provided on the rotating cover 2 will also move accordingly. The stopper 212 can move along the groove 115, so that the stopper 212 can change its position in the groove 115 and change the blocking amount of the first hole 116 by the stopper 212, that is, the connectivity between the first hole 116 and the recess 21 changes, and the sound volume instantaneously transmitted to the recess 21 changes, that is, the instantaneous sound volume ultimately transmitted from the second hole 22 will change, and the result of the superposition of the sound with the sound transmitted from the main sound outlet 1141 will also change, that is, the treble and bass effects of the sound produced by the earphones using the treble and bass adjustment structure of the present earphones will change, until the user finds the effect that meets the needs, the rotation of the rotating cover 2 can be stopped.

[0035] In addition, by providing structures such as the groove 115 and the limiting groove 113 , it can be ensured that the blocking amount of the first hole 116 by the stopper 212 changes each time the rotating cover 2 is rotated.

[0036] The above are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present invention, which all fall within the scope of protection of the present invention.
