Description

Technical Field

[0001] The present invention relates to the technical field of headphones, in particular to a head-mounted headphone capable of protecting a user from identifying the outside world safely. Background Art

[0002] To achieve superior sound quality, current headphones and cycling earphones on the market typically completely enclose the ear canal. However, this design has significant drawbacks: Firstly, headphones are bulky, compromising comfort; secondly, they completely block out external sounds while the user is enjoying music, making it impossible for the auditory system to detect danger or emergencies during cycling or daily use. Meanwhile, in-ear headphones, another popular design, while compact, are placed directly into the ear canal. Long-term use can not only breed bacteria and cause ear infections, but can also damage the eardrum due to prolonged sound stimulation. Summary of the Invention

[0027] Example

[0028] 1 to 7, an embodiment of the present invention is provided, which provides a headset for protecting the user from identifying the outside world, including a speaker structure 900, the speaker structure 900 includes a magnetic circuit system 200, a vibration membrane 300 and a high-frequency magnetic shielding ring 400, wherein the magnetic circuit system 200, the vibration membrane 300 and the high-frequency magnetic shielding ring 400 The shielding ring 400 adopts a hollow ring structure, forming an acoustic channel 500 that runs through the earphone; the magnetic circuit system 200 includes a magnetic ring 201, a magnetic material 202 and a support frame 203. The magnetic material 202 is assembled in the magnetic ring 201 and fixed as a whole in the support frame 203; the magnetic ring 201 includes a first magnetic conductive sheet 201a and a second magnetic conductive sheet 201b. The two are coaxially nested in the support frame 203 to form an annular magnetic gap 201c; the vibration membrane 300 and the coil 301 are bonded and assembled in the magnetic gap of the magnetic circuit system, and the central area of ​​the vibration membrane 300 is a hollow open structure; a conductive terminal plate 600 is provided on the surface of the support frame 203, and the end of the coil 301 is welded to the conductive terminal plate 600. An annular assembly groove 203a is provided on the edge of the support frame 203 for fixing the magnetic circuit system 200; it also includes a tuning mesh 700 and a protective cover 800, which are sequentially covered on the outside of the support frame 203, the tuning mesh 700 is attached to the surface of the support frame 203, and the surface of the protective cover 800 is provided with mesh holes 800a, and the protective cover 800 is arranged on the outermost layer; the high-frequency magnetic shielding ring 400 is an annular short-circuit ring, which is covered on the outer edge of the magnetic circuit system 200; the magnetic circuit system 200, the vibration membrane 300 and the high-frequency magnetic shielding ring 400 The hollow axis 401 of the earphone coincides with the hollow axis 401, forming a sound wave conduction channel 501 running through the front and rear ends of the earphone. The sound wave conduction channel 501 completely coincides with the acoustic channel 500 and is integrated into the annular frame structure space of the support frame 203; the support frame 203 is an annular frame structure, and an annular assembly groove 203a is provided on its inner side for locking the assembly of the magnetic ring 201 and the magnetic material 202; it also includes a headband 101, a shell 102 and an ear pad 103. Two shells 102 are provided at both ends of the headband 101, and the shell 102 is provided with an ear pad 103. The sound speaker structure 900 is arranged in the shell 102 and is located between the shell 102 and the ear pad 103. The shell 102 is provided with a first air vent 102a, and the ear pad 103 is provided with a second air vent 103a, so that the acoustic channel 500 of the sound speaker structure 900 is connected to the outside world.

[0029] Specifically, magnetic circuit system 200 is the core of acoustic and electromagnetic functions: its first magnetic conductive sheet 201a and second magnetic conductive sheet 201b are coaxially nested in an annular mounting groove 203a on the inner side of support frame 203, forming an annular magnetic gap 201c. Magnetic material 202 is embedded within the magnetic conductive ring to enhance the magnetic field. The assembly of magnetic material 202 and magnetic conductive ring 201 is locked in place by the annular mounting groove 203a of support frame 203, ensuring structural stability.

[0030] After the edges of the diaphragm 300 are bonded to the coil 301, they are precisely assembled within the magnetic gap 201c of the magnetic circuit system. The central open area aligns with the hollow portion of the magnetic circuit system 200, ensuring a clear path for sound waves to pass through. The ends of the coil 301 are welded to the conductive terminal block 600 on the surface of the support frame 203, ensuring electrical continuity.

[0031] The high-frequency magnetic shielding ring 400 short-circuit ring cover is arranged at the outer edge of the magnetic circuit system 200, which not only suppresses electromagnetic interference, but also coincides with the axis of the acoustic channel 500 due to its annular hollow design, avoiding blocking the transmission of sound waves.

[0032] Support frame 203 serves as a load-bearing framework: its annular frame secures the magnetic circuit system via annular mounting grooves 203a. A tuning mesh 700 is attached to its surface to adjust acoustic properties. The outermost layer is covered by a protective cover 800. The mesh 800a on the surface of the protective cover 800 allows sound waves to penetrate in both directions while protecting the internal components.

[0033] During full integration, the speaker structure 900 is installed between the earphone housing 102 and the ear pad 103. The first vent 102a in the housing 102 and the second vent 103a in the ear pad 103 are connected to both ends of the acoustic channel 500, forming a complete ambient sound transmission path: external sound waves → cover mesh 800a → acoustic channel 500 → ear pad vent 103a → user's ear canal. Working Principle: The hollow axes 401 of the magnetic circuit system 200, diaphragm 300, and high-frequency magnetic shielding ring 400 completely overlap, forming an acoustic channel 500 that runs through the front and back of the earphones. When the user wears the earphones, ambient sound waves (such as vehicle horns and human voice warnings) are transmitted directly into the ear canal through this channel, without relying on electronic pickup or noise reduction.

[0034] During audio playback, the magnetic circuit system 200 generates a circular magnetic field: the magnetic material 202 is embedded in the magnetic ring 201, which is composed of a first magnetic conductive sheet 201a and a second magnetic conductive sheet 201b, forming a high-strength magnetic gap 201c. The vibrating membrane 300 bonded to the coil 301 is assembled in this magnetic gap. When powered, it is driven by the magnetic field to vibrate and produce sound. Because the central area of ​​the vibrating membrane 300 is an open design, the electronic sound waves generated by its vibration do not block the ambient sound. Instead, they are mixed with the ambient sound and transmitted to the ear through the acoustic channel 500. The high-frequency magnetic shielding ring 400 (annular short-circuit ring) covers the outer edge of the magnetic circuit system, effectively suppressing electromagnetic interference and ensuring signal purity. It is worth mentioning that the damping optimization of the vibration membrane 300 + tuning mesh 700 achieves an ultra-wide frequency response of 20Hz-20kHz (traditional headphones often sacrifice high frequencies). The hollow structure reduces ear pressure by 30%, reducing the risk of ear canal infection. The high-frequency magnetic shielding ring 400 suppresses more than 90% of electromagnetic interference to ensure the clarity of sound quality. The magnetic conductive sheet 201a / 201b (thin-walled aluminum alloy) is nested and locked in the annular assembly groove 203a of the support frame 203, and the magnetic material 202 (lightweight neodymium magnet) is embedded therein. The annular hollow design removes redundant mass and greatly reduces the amount of magnets used. The vibration membrane 300 uses carbon fiber to achieve high rigidity / lightweight. The central open area is coaxial with the acoustic channel 500. The high-frequency magnetic shielding ring 400 uses an aluminum short-circuit ring to cover the outer edge of the magnetic circuit system to reduce weight. Its annular hollow coincides with the axis of the channel 500, and there is zero sound wave obstruction.
