Description

Technical Field

[0001] This application relates to the field of earmuff structures, and more particularly to a physical noise-canceling earmuff that can be connected to an external communication device. Background Technology

[0002] Earmuffs are ear protectors that cover the entire ear canal, effectively protecting hearing. They consist of two cylindrical shells connected by a frame, with sound-absorbing material and sealing gaskets inside, resembling headphones in shape. However, unlike headphones, which focus on providing entertainment and communication experiences, earmuffs primarily reduce or isolate noise, prioritizing ear protection. They are typically worn in noisy environments where people working often need communication skills and also require entertainment to maintain a pleasant mood.

[0003] Traditional noise-canceling headphones or earmuffs, in order to meet the needs of the aforementioned groups, add audio functions and employ active noise cancellation to isolate noise. However, active noise-canceling earmuffs actually achieve noise reduction by interfering with sound waves. Due to the delay in circuit feedback, they cannot reduce sudden noise. Furthermore, active noise-canceling headphones are relatively poor at reducing high-frequency noise. Therefore, there is an urgent need in the market for earmuffs that offer good sound isolation while also providing good communication functionality. Utility Model Content

[0004] To address the market's lack of communication-enabled earmuffs and improve the structure of existing earmuffs, this application provides a physical noise-canceling earmuff that can be connected to an external communication device.

[0005] The physical noise-canceling earmuffs that can be connected to external communication devices provided in this application adopt the following technical solution:

[0006] A physical noise-canceling earmuff with an external communication device includes an arched connector, a cover body symmetrically hinged to both ends of the arched connector, and two ear pads respectively installed inside the cover body. The cover body is a one-piece structure with an inner liner for sound insulation. A stepped groove is formed on the inner side of the upper edge of the cover body, and a mounting plate is fitted in the stepped groove. A grid is provided in the middle of the mounting plate, and a speaker is installed on the mounting plate on the side of the grid near the inner liner. An outer shell is detachably fitted on the outer side of the cover body. An interactive component with communication function is detachably installed inside the outer shell. The interactive component is coupled to the speaker. Several control buttons are installed on the side of the outer shell away from the cover body, and the several control buttons are electrically connected to the interactive component.

[0007] Optionally, the interactive components include at least one of the following: a chip, a sound card, a Bluetooth module, a filter, an audio receiver, and an audio transmitter.

[0008] Optionally, the edge of the cover is provided with a mating hole, and the mounting plate is connected with a connector that matches the shape of the mating hole. The connector extends out of the cover and has a through hole. The outer shell is provided with a connecting tube corresponding to the connector for wire passage. The end of the connecting tube is mated with the connector.

[0009] Optionally, a wiring groove for placing wires is provided on the side of the mounting plate away from the speaker. The other end of the wiring groove is connected to the wire hole. Wires are placed in the wiring groove, and the depth of the wiring groove is greater than the diameter of the wires.

[0010] Optionally, a microphone connector is connected to the outer shell, and the port of the microphone connector is coupled to a microphone that can be used for communication.

[0011] In summary, this application includes at least one of the following beneficial technical effects:

[0012] 1. The communication device of this application is detachable, and the interactive components therein can be freely installed and removed electronic components, thereby making the earmuffs more customizable and applicable to a wider range of situations;

[0013] 2. The earcups of this application can effectively control the overall weight of the earcups by freely changing the structure of the interactive components and the detachable outer shell, making them convenient for long-term wear;

Detailed Implementation

[0020] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0021] This application discloses a physical noise-canceling earmuff that can be connected to an external communication device.

[0022] Reference Figure 1 and Figure 2 A physical noise-canceling earmuff compatible with external communication devices includes an arched connector 1 for fitting the wearer's head, a cover body 2 symmetrically hinged to both ends of the arched connector 1, and two ear pads 3 respectively fixedly connected to the inner side of the cover body 2. The connection between the ear pads 3 and the cover body 2 can be achieved through various methods such as snap-fit, adhesive, or fastening. An inner liner 21 is fixedly installed inside the cover body 2, which effectively absorbs sound and improves the earmuff's sound insulation. Simultaneously, a cavity is provided between the inner liner 21 and the inner wall of the cover body 2, further enhancing the noise-canceling effect.

[0023] Preferably, the earcup body 2 in this application is a one-piece structure, which can avoid the impact of reduced sound insulation caused by openings, and make the wearer's experience better.

[0024] Reference Figure 2 and Figure 3 Furthermore, a stepped groove 22 is provided circumferentially along the edge of the earcup 2, and a mounting plate 4 is fitted into the stepped groove 22. The mounting plate 4 is located between the ear pad 3 and the inner shell 21. A mesh 41 is integrally formed in the middle of the mounting plate 4 to isolate impurities and prevent them from entering the earcup, while allowing sound from inside the earcup to reach the wearer's ear. A speaker 42 is installed on the side of the mounting plate 4 near the inner shell 21 at the mesh 41. The speaker 42 can be connected to electronic components to transmit sound signals.

[0025] Furthermore, an outer shell 5 is detachably attached to the outer side of the cover 2, and a cavity is formed inside the outer shell 5. An interactive component 6 with communication functions is detachably installed within the cavity. The interactive component 6 can transmit sound signals and various other electrical signals. The interactive component 6 is coupled to the speaker 42 via a wire, transmitting the sound signals and other informational electrical signals to the speaker 42, which then converts them into sound signals for the wearer to hear. Several control buttons are installed on the outer shell 5 on the side opposite to the cover 2. These control buttons are electrically connected to the interactive component 6 to control the operating status of the electronic components.

[0026] Preferably, the interactive component 6 specifically includes at least one of the following: a chip, a sound card, a Bluetooth module, a filter, an audio receiver, and an audio transmitter, enabling the earcups to perform multiple interactive functions such as intercom, calls, monitoring, sound pickup, and wireless connection, and not just limited to transmitting sound. In actual use, the electronic components inside the outer shell 5 of this application can be customized and removed according to the wearer's requirements to adapt to the different usage needs of different users.

[0027] Based on the structure of the external communication and interaction element, this application enables communication and interaction without compromising the noise reduction and sound insulation function of the earcups themselves, resulting in better physical noise reduction compared to other earcups on the market. Moreover, because this application uses an earcup with a physical noise reduction structure, it can be worn for extended periods without causing discomfort, thanks to its active noise cancellation.

[0028] Reference Figure 2 and Figure 4 Furthermore, the cover 2 has a mating hole 23 at its edge, and the mounting plate 4 has an integrally connected connector 43 that matches the mating hole 23. When the mounting plate 4 is installed on the cover 2, the connector 43 is engaged in the position of the mating hole 23, thereby limiting the rotation of the mounting plate 4. Of course, for this application, the cross-section of the cover 2 is a near-elliptical structure, so the limiting effect of the above structure is not significant.

[0029] The connector 43 is equipped with a connecting tube 51 that is adapted to the size and shape of the connector 43, and the end of the connecting tube 51 is connected to the connector 43 for threading wires, so that the speaker 42 and the electronic components in the outer shell 5 can be smoothly connected to the speaker 42. The connector 43 is provided with a wire through hole 431, and during installation, the wires on the speaker 42 enter the outer shell 5 through the wire through hole 431.

[0030] The advantage of this structure is that the opening at the edge of the cover 2 does not damage the structure of the cover 2 itself, thus ensuring the integrity of the sound insulation and noise reduction structure.

[0031] Reference Figure 4Furthermore, a wiring groove 44 for placing wires is provided on the side of the mounting plate 4 away from the speaker 42, and the other end of the wiring groove 44 is connected to the wire hole 431 on the connector 43. Wires with both ends connected to the speaker 42 and the electronic components in the outer housing 5 are placed in the wiring groove 44, and the diameter of the wires is smaller than the depth of the wiring groove 44.

[0032] When the earmuffs are in normal use, the wires are located in the cable tray 44. When the wearer wears the earmuffs, the ear pads 3 will not squeeze the wires, thus avoiding unstable sound signals.

[0033] Reference Figure 1 and Figure 4 Preferably, a microphone connector 52 is connected to the outer shell 5, and a microphone 7 is coupled to the port of the microphone connector 52. The microphone 7 can be used for communication, enabling two-way interactive communication between the wearer and the external signal.

[0034] The implementation principle of a physical noise-canceling earmuff that can be connected to an external communication device according to an embodiment of this application is as follows:

[0035] This application allows the wearer to customize the interactive functions of the earmuffs according to their actual usage needs by detachably attaching an outer shell 5 to the outside of the earmuff body 2, thereby greatly improving the practicality of the earmuffs.

[0036] Furthermore, when the wearer does not require the interactive function, the outer shell 5 can be removed, which can reduce the weight of the earcups and improve the user's ear comfort during long-term wear.

[0037] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
