In order to meet consumers' higher requirements for sound quality experience, the design of the vibration unit must be innovated and improved.

[0004] Although the headphones currently on the market have made breakthroughs in sound quality, they still lack the ability to deeply restore special scenes and cannot provide consumers with an immersive listening experience. Utility Model Content

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] The utility model provides an earphone vibration unit, such as Figure 1-Figure 3 As shown, it includes a plastic shell 1, which plays an insulating role to reduce the influence of external iron on the voice coil 2 and magnetism. The voice coil 2 is installed on the inner bottom surface of the plastic shell 1, a washer 3 is installed on the outer side of the voice coil 2, a magnet 4 is installed on the outer side of the washer 3, an aluminum ring 6 is installed on the outer side of the magnet 4, a spring 7 is installed on the outer side of the aluminum ring 6, and a protective cover 8 is installed on the outer side of the plastic shell 1. The voice coil 2, the washer 3, the aluminum ring 6, and the spring 7 are fixed by a copper shaft 5.

[0024] In this embodiment, the washer 3 is used for magnetic conduction, and the N pole and the S pole of the magnet 4 are concentrated into the gap through the loop, so as to generate a stronger magnetic field in the gap.

[0025] Specifically, one side of the voice coil 2 is connected to the internal conductive unit of the earphone. After the voice coil 2 is conductive, it moves in the magnetic field according to Fleming's left-hand rule, thereby driving the spring 7 to vibrate, thereby achieving vibration and amplification of the sound.

[0026] Furthermore, the copper shaft 5 sequentially penetrates the voice coil 2 , the washer 3 aluminum ring 6 , and the spring 7 . A positioning hole 81 is provided in the middle of the protective cover 8 , and the end of the copper shaft 5 is clamped in the positioning hole 81 .

[0027] Furthermore, when a changing current is passed into the speaker of the headset, the magnet 4 forms an electromagnet due to the power supply, and the direction of the current keeps changing. The electromagnet also keeps moving back and forth due to the force of the energized wire in the magnetic field, driving other parts to vibrate back and forth, making the headset sound quality produce a vibration effect.

[0028] Furthermore, after the aluminum ring 6 generates magnetism, the current is different, the magnitude of the magnetism changes, and then the shrapnel 7 moves under the action of the magnet 4, generating vibration, thereby generating sound.

[0029] Furthermore, the spring piece 7 is made of metal material and has good conduction effect. After the spring piece 7 is energized, the voice coil 2 generates magnetism, which repel the magnet 4 and generate fluctuations, driving the spring piece 7 to move back and forth, thereby generating a vibration effect.

[0030] Furthermore, the protective cover 8 plays a protective role, protecting the spring piece 7 and other parts to avoid damage, destruction and deformation. The protective cover 8 is screwed on the end of the plastic shell 1 through a thread, thereby limiting the spring piece 7 inside the plastic shell 1 to prevent the spring piece from popping out.

[0031] When the earphone vibration unit of the utility model is in use, first, when the audio signal is transmitted to the vibration unit, the signal is converted into current and transmitted to the voice coil 2. After receiving the current, the voice coil 2 begins to conduct electricity. At this time, the washer 3 located outside the voice coil 2 plays a magnetic conduction role, concentrating the magnetic lines of force of the N pole and the S pole of the magnet 4 through the loop to the gap between the voice coil 2 and the washer 3, thereby generating a strong magnetic field in the gap.

[0032] In a strong magnetic field, according to Fleming's left-hand rule, the voice coil 2 with power on will be acted upon by a force and start to move. This movement will drive the spring 7 above to vibrate together, thereby producing sound. In this process, the aluminum ring 6 will also generate magnetism, and its magnetism will also change with the change of current, which further affects the vibration frequency and amplitude of the spring 7.

[0033] At the same time, as a metal material, the spring piece 7 has good electrical conductivity. When the spring piece 7 is energized, a repulsive force will be generated between it and the magnet 4. This repulsive force will cause the spring piece 7 to fluctuate, thereby enhancing the vibration effect and achieving sound amplification.

[0034] In addition, the entire vibration unit is fixed between the plastic shell 1 and the protective cover 8, ensuring the stability and durability of each component. The protective cover 8 not only protects the internal components from damage, but also acts as a limiter to ensure that the spring piece 7 will not pop out during vibration.

[0035] In general, the earphone vibration unit of the present invention converts the audio signal into mechanical vibration through electromagnetic induction and magnetic field, and then amplifies and propagates the sound through the vibration of the spring 7, thereby achieving efficient and stable sound output.

[0036] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection of the utility model is defined by the attached claims and their equivalents.
