Description

Technical Field

[0001] This application relates to the field of headphone equipment technology, and more particularly to a headphone with a mechanical adjustment of external volume. Background Technology

[0002] Currently, there are various types of headphones commonly found on the market, including in-ear headphones, over-ear headphones, ear-hook headphones, and neckband headphones. Some modern headphones use ear tips or earmuffs to seal the ear, creating a closed, confined space that isolates external sound, providing excellent noise isolation (such as in-ear and over-ear headphones). This can meet the needs of most consumers for both sound quality and noise isolation.

[0003] However, while offering excellent sound isolation, these types of headphones can also cause inconvenience or even harm to users during daily use. For example, excessive sound isolation can prevent users from responding properly to external sounds (such as difficulty communicating with others or avoiding oncoming vehicles or pedestrians while walking).

[0004] Therefore, the aforementioned technical defects urgently need to be addressed. Summary of the Invention

[0005] In view of the shortcomings of the prior art, the purpose of this application is to provide a headphone with mechanical adjustment of external volume, which aims to improve the practicality and convenience of the headphone.

[0007] One end of the adjustable opening valve is connected to the external environment, and the other end of the adjustable opening valve is connected to the sound outlet through a connecting channel; the opening degree of the adjustable opening valve is adjustable so that the volume of the external environment received by the sound outlet is adjustable.

[0008] In one possible implementation, both the left and right earphone bodies include:

[0009] The earphone shell has a recessed receiving groove, a speaker opening in the receiving groove, and a sealing cover is inverted in the receiving groove corresponding to the position of the speaker opening. The sealing cover and the inner wall of the receiving groove are spliced ​​together to form a speaker chamber, and a speaker is installed in the speaker chamber.

[0010] Elastic cushioning ear tips are detachably attached to one end of the headphone shell and are positioned around the speaker opening.

[0011] And the middle shell cover, which is located on the middle shell of the earphone away from the ear tip, and is used to seal the receiving groove;

[0012] The adjustable opening valve is located on the sealing cover or the middle shell cover.

[0013] In one possible implementation, the adjustable opening valve includes:

[0014] A movable base is mounted on a sealing cover or a middle shell cover, and a first valve through hole is provided on the movable base that penetrates the sealing cover.

[0015] And the valve knob, which is movably connected to the movable base via a rotating shaft, and the valve knob passes through and protrudes from the middle shell cover;

[0016] The valve knob has a second valve through hole at the position corresponding to the first valve through hole. The second valve through hole is connected to the external environment. Both the first valve through hole and the second valve through hole are offset from the axis of the rotating shaft and are arranged opposite to each other.

[0017] In one possible implementation, the connecting channel is disposed on the sealing cover, extends along the inner wall of the sealing cover, and its two ends are respectively connected to the first valve through hole and the sound through hole.

[0018] In one possible implementation, the shape and size of the first valve through hole and the second valve through hole are the same, and both the first valve through hole and the second valve through hole are fan-shaped through holes.

[0019] In one possible implementation, at least one limiting member is provided on the movable base near the first valve through hole. The limiting member is integrally formed with the movable base, protrudes from the movable base, and penetrates the second valve through hole.

[0020] In one possible implementation, a gear shifting engagement piece is provided on the movable base, and several engagement grooves are provided on the valve knob at positions corresponding to the gear shifting engagement piece. The gear shifting engagement piece and the engagement grooves constitute a gear shifting mechanism for providing feedback on the rotation gear of the valve knob.

[0021] In one possible implementation, at least one of the first valve through-hole and the second valve through-hole is configured as an obtuse-angled triangular hole.

[0022] In one possible implementation, the movable base is integrally formed with the sealing cover, and the sealing cover has a vent hole for venting the speaker chamber.

[0023] In one possible implementation, a PCB circuit board is disposed in the receiving slot, the speaker is electrically connected to the PCB circuit board, and at least one control button is disposed on the PCB circuit board.

Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0036] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0037] Furthermore, the technical features involved in the different embodiments of the present invention described above can be combined with each other as long as they do not conflict with each other.

[0038] This invention provides, for example Figure 1 , Figure 2 and Figure 3 As shown, a type of mechanically adjustable earphone is a personal audio device that converts electrical signals into sound. It generates sound waves by vibrating air through a drive unit (such as a dynamic coil or balanced armature), directly transmitting the sound to the wearer's ears. The main structure includes a left earphone body 01 and a right earphone body 02 connected by wired or wireless means. Both the left and right earphone bodies 01 and 02 are equipped with a speaker 14, a sound-through hole 12, and an adjustable opening valve 15. The speaker 14 is positioned opposite the sound-through hole 12, which is connected to the user's ear canal. With the adjustable opening valve 15, when the valve is open, the user's ear canal is connected to the external environment, allowing the user to directly hear ambient sounds. Specifically, one end of the adjustable opening valve 15 is connected to the external environment, and the other end is connected to the sound-through hole 12 via a connection channel 132. The opening degree of the adjustable opening valve 15 is adjustable, allowing the ambient sound volume received by the sound-through hole 12 to be adjusted. Simultaneously, the adjustable opening valve 15 can be completely closed or opened. In some embodiments, the present invention can be applied to a single left or right earphone.

[0039] It's important to note that some headphones today seal the ear canal with ear tips or earmuffs, creating a small, enclosed space that effectively isolates external sounds, providing excellent noise isolation (such as in-ear and over-ear headphones). This satisfies most consumers' needs for sound quality and noise isolation. However, while offering excellent noise isolation, these headphones can also cause inconvenience or even harm during daily use. For example, excessive noise isolation can prevent users from responding properly to external sounds (e.g., difficulty communicating with others, or being able to avoid oncoming vehicles or pedestrians while walking).

[0040] During use, the user can open or close the adjustable opening valve 15 as needed. When the adjustable opening valve 15 is open, the user can also adjust the opening degree of the valve 15 to change the size of the connection channel 132 between the speaker hole 12 and the external environment, thereby changing the volume transmitted from the external environment to the user's ears. This allows the user to adjust the volume of the external environment as needed, effectively improving the practicality and convenience of the headphones.

[0041] Furthermore, such as Figure 1 , Figure 2 and Figure 3As shown, both the left earphone body 01 and the right earphone body 02 include: an earphone shell 1, an elastic cushioning ear tip 2, and a shell cover 3. The elastic cushioning ear tip 2 in the above embodiments is typically found in over-ear headphones. In other embodiments, earplugs are used instead of the elastic cushioning ear tip 2. The adjustable opening valve 15 in this invention is applicable to both over-ear and in-ear headphones; this embodiment is specifically described using over-ear headphones. The earphone shell 1 has a recessed receiving groove 11, within which a speaker through-hole 12 is opened, communicating with the user's ear canal. A sealing cover 13 is inverted within the receiving groove 11 corresponding to the position of the speaker through-hole 12. The sealing cover 13 and the inner wall of the receiving groove 11 are joined to form a speaker chamber 131, within which a speaker 14 is installed. It is understood that the speaker chamber 131 formed by the sealing cover 13 in this embodiment allows for better sound pressure when the speaker 14 is operating, preventing sound pressure leakage from the speaker 14 in the gaps of the earphone shell. Meanwhile, the sealing cover 13 also improves the sound isolation of the headphones. The elastic buffer ear tips 2 are detachably connected to one end of the headphone shell 1, and are positioned around the speaker opening 12; the shell cover 3 is located on the end of the headphone shell 1 opposite to the ear tips, and is used to seal the receiving groove 11; wherein, an adjustable opening valve 15 is provided on the sealing cover 13 or the shell cover 3. Figure 4 As shown, in this embodiment, the adjustable opening valve 15 is installed on the sealing cover 13. The size of the opening between the sealing cover 13 and the external connection channel 132 can be directly adjusted through the adjustable opening valve 15, thereby achieving the technical effect of adjusting the volume of external ambient sound. In some other embodiments, the adjustable opening valve 15 can also be installed on the middle shell cover 3, and then connected to the speaker through hole 12 through the connection channel 132.

[0042] Furthermore, such as Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the adjustable opening valve 15 includes a movable base 151 and a valve knob 152. The movable base 151 is mounted on the sealing cover 13 or the middle shell cover 3. Specifically, the movable base 151 is integrally formed with the sealing cover 13 or the middle shell cover 3. A first valve through hole 1511 is provided on the movable base 151, which passes through the sealing cover 13. The valve knob 152 is movably connected to the movable base 151 via a rotating shaft 153, and the valve knob 152 passes through and protrudes from the middle shell cover 3. A second valve through hole 1521 is provided on the valve knob 152 at a position corresponding to the first valve through hole 1511. The second valve through hole 1521 communicates with the external environment. Both the first valve through hole 1511 and the second valve through hole 1521 are offset from the axis of the rotating shaft 153, and the first valve through hole 1511 and the second valve through hole 1521 are arranged opposite to each other.

[0043] In Embodiment 1, an adjustable opening valve 15 is disposed on a sealing cover 13. A movable base 151 is disposed on the sealing cover 13, and a first valve through-hole 1511 on the movable base 151 communicates with a speaker through-hole 12 via a connecting channel 132 or a speaker chamber 131 on the sealing cover 13.

[0044] In embodiment two, an adjustable opening valve 15 is provided on the middle shell cover 3. A movable base 151 is provided on the middle shell cover 3, and the first valve through-hole 1511 on the movable base 151 communicates with the speaker through-hole 12 through a cavity inside the middle shell cover 3 or a connecting channel 132.

[0045] Furthermore, such as Figure 5 As shown, the connecting channel 132 is provided on the sealing cover 13. The connecting channel 132 extends along the inner wall of the sealing cover 13, and the two ends of the connecting channel 132 are respectively connected to the first valve through hole 1511 and the sound through hole 12.

[0046] It should be noted that the speaker opening 12 on the headphones is typically a mesh-like opening, with the speaker 14 covering the speaker opening 12. Furthermore, the speaker chamber 131 formed inside the sealing cover 13 is separated from the speaker opening 12 by the speaker 14. Therefore, to prevent the diaphragm on the speaker 14 from separating the user's ear canal space from the adjustable opening valve 15 and affecting the reception of ambient sound, in this embodiment, a connecting channel 132 is provided on the sealing cover 13, directly connecting to the user's ear canal.

[0047] In some other embodiments, an ambient sound passage is provided on the middle shell cover 3 at the position corresponding to the elastic buffer ear sleeve 2, and the adjustable opening valve 15 is connected to the ambient sound passage through the connecting channel 132. This can prevent ambient sound from being affected by the speaker 14.

[0048] Furthermore, such as Figure 4 , Figure 5 As shown, the first valve through-hole 1511 and the second valve through-hole 1521 have the same shape and dimensions, and both are fan-shaped through-holes. In this embodiment, both the first valve through-hole 1511 and the second valve through-hole 1521 are set as fan-shaped through-holes, and their dimensions and shapes are the same. When the valve knob 152 is at its maximum opening, the first valve through-hole 1511 and the second valve through-hole 1521 correspond to each other, and the valve opening formed by the first valve through-hole 1511 and the second valve through-hole 1521 is at its maximum. When the valve knob 152 is closed, the first valve through-hole 1511 and the second valve through-hole 1521 are completely offset, making them not interconnected. This achieves the technical effect of sound insulation.

[0049] Furthermore, such as Figure 4As shown, at least one limiting member 1512 is provided on the movable base 151 near the first valve through hole 1511. The limiting member 1512 is integrally formed with the movable base 151, protrudes from the movable base 151, and penetrates through the second valve through hole 1521. In this embodiment, the protruding limiting member 1512 restricts the rotation angle of the valve knob 152. Specifically, the protruding limiting member 1512 penetrates through the second valve through hole 1521, so that the valve knob 152 can only rotate around the extension range of the second valve through hole 1521 when it rotates. The protrusion height of the limiting member 1512 is less than or equal to the depth of the second valve through hole 1521.

[0050] Furthermore, such as Figure 4 As shown, a gear shift latching member 1513 is provided on the movable base 151, and several latching grooves 1522 are provided on the valve knob 152 corresponding to the positions of the gear shift latching member 1513. The gear shift latching member 1513 and the latching grooves 1522 constitute a gear shifting mechanism for providing feedback on the rotation gear of the valve knob 152. It can be understood that in this embodiment, a gear shifting mechanism is provided between the movable base 151 and the valve knob 152, which allows the user to easily control the opening degree of the adjustable valve 15 when rotating the valve knob 152. Simultaneously, during the rotation of the valve knob 152, the gear shifting mechanism provides feedback with a damping feel and a latching sound. This effectively improves the effectiveness and feel of the valve knob 152's rotation adjustment.

[0051] Furthermore, such as Figure 7 As shown, at least one of the first valve through-hole 1511 and the second valve through-hole 1521 is configured as an obtuse-angled triangular hole. It is understood that the longer the extension length of the first valve through-hole 1511 and the second valve through-hole 1521, the greater the adjustable range of the valve opening of the valve knob 152. Therefore, in this embodiment, at least one of the first valve through-hole 1511 and the second valve through-hole 1521 is configured as an obtuse-angled triangular hole.

[0052] Furthermore, such as Figure 4 , Figure 5 As shown, the movable base 151 and the sealing cover 13 are integrally formed. The sealing cover 13 has a vent hole 133 for venting the speaker chamber 131. It is understood that the movable base 151 is connected to the speaker through-hole 12 via the connecting channel 132. This effectively prevents the speaker 14 from obstructing the connection between the adjustable opening valve 15 and the user's ear canal. However, when the speaker 14 is operating, the speaker chamber 131 formed inside the sealing cover 13 will affect the vibration amplitude of the speaker 14 diaphragm. Therefore, in this embodiment, a vent hole 133 is provided on the sealing cover 13 to balance the internal and external air pressure of the speaker chamber 131, thus avoiding interference with the normal operation of the speaker 14.

[0053] Furthermore, such as Figure 3 As shown, a PCB circuit board 111 is provided in the receiving slot 11, the speaker 14 is electrically connected to the PCB circuit board 111, and at least one control button 1111 is provided on the PCB circuit board 111.

[0054] Understandably, headphones usually have control buttons 1111, which are used to adjust the volume or turn the headphones on and off.

[0055] In summary, this application provides a mechanically adjustable headphone for external volume control. During use, the user can open or close the adjustable opening valve 15 as needed. When the adjustable opening valve 15 is open, the user can also adjust the opening degree of the valve 15 to change the size of the connection channel 132 between the speaker aperture 12 and the external environment, thereby changing the volume transmitted from the external environment to the user's ears. This allows the user to adjust the external volume as needed, effectively improving the practicality and convenience of the headphone.

[0056] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
