Description

Technical Field

[0001] The utility model relates to the technical field of earphones, in particular to an earphone monomer structure. Background Art

[0002] High-resolution headphones usually have precise driver units and optimized sound channel design, which can present clear and vivid sound effects, and provide rich details and wide frequency response regardless of the type of music. There are three main types of high-resolution headphone structures: voice coil type, dynamic iron type and hybrid type, among which:

[0003] The driving unit of voice coil headphones consists of a coil and a permanent magnet. When the current passing through the coil changes, it generates force in the magnetic field to move the coil, which in turn causes the diaphragm connected to the coil to vibrate and make sound. Its advantages include providing clearer and more detailed sound quality, a looser and more natural sound, fuller mid-frequency and low-frequency performance, and being more suitable for listening to pop music, rock music, etc.

[0004] Dynamic armature earphones transmit the energy to the center point of a miniature diaphragm through a precisely structured connecting rod, thereby generating vibrations and making sounds. Their advantage is that they can provide more consistent and powerful sound quality, and the sound quality is warmer and mellower, with better reproduction of details and clearer sound lines. They are suitable for listening to vocals, classical music, and other types of music that require richer and more delicate sound performance.

[0005] Hybrid earphones combine the technologies of dynamic coil and balanced armature. Usually the dynamic coil unit is responsible for low frequencies, while the balanced armature unit is responsible for mid- and high-frequency frequencies. Their advantage is that they can have the advantages and performance of both dynamic coil and balanced armature, providing a more comprehensive sound experience.

[0006] However, in actual use, the disadvantage of hybrid headphones is that the three frequencies often interfere with each other. The disadvantages of dynamic iron headphones include narrow frequency response, unnatural sound, and poor performance in low frequencies. The disadvantages of voice coil headphones are mainly complex structure, which leads to increased power consumption, increased background noise, and easy mutual interference.

[0007] In particular, most traditional voice coils have a circular structure and are not encapsulated on the outside. It is technically difficult to install them inside in-ear headphones with limited space like a high-fidelity audio system, so further improvements are necessary. Utility Model Content

[0056] More specific instructions, such as Figures 1 to 6 As shown, the application method of the earphone monomer structure of the utility model mainly includes:

[0057] A headphone monomer structure 100 is constructed, which has a vibration system 10, a magnetic circuit system 20, and a support system 30, wherein the vibration system 10 is at least composed of a diaphragm 11 connected to a voice coil 12, and the diaphragm 11 is rectangular; the magnetic circuit system 20 is at least composed of a washer 21 combined with a magnet 22, and a magnetic gap is formed between the washer 21 and the magnet 22 to allow the voice coil 12 to be suspended and placed; and the support system 30 is at least composed of a bottom frame 31, a protective sheet 32, and a shell 33 that are connected and nested, and the magnetic circuit system 20 and the vibration system 10 are placed therein, and the following method is performed:

[0058] S101. The rectangular diaphragm 11 inside the earphone monomer structure 100 has the voice coil 12 on one side and a coil 35 with a reverse magnetic circuit on the other side.

[0059] S102. The bottom frame 31, the protective sheet 32, and the housing 33 are formed outside the earphone monomer structure 100 to form a small rectangular speaker box with enhanced protection, and a sound outlet 36 for external sound is also provided next to it;

[0060] S103. The voice coil earphone monomer structure 100 as a whole has a moving iron-like enclosure and a push-pull output effect.

[0061] The utility model combines the advantages of voice coil type and moving iron type, so that the earphone monomer can provide higher resolution, make the sound clearer and more detailed. The structure of the earphone monomer is simple, easy to assemble, low in manufacturing cost, stable in vibration, and has a frequency response with excellent output sound quality. Figure 7 As shown, it can be conveniently modularized into large and small units according to different audio outputs, and then arranged in parallel according to the best audio selection or customized preferences, such as high-fidelity audio combination, and installed inside high-resolution headphones with limited space.

[0062] The product can not only be used with smart phones and voice assistants, but also is suitable for making various high-resolution headphones of different levels, such as wireless Bluetooth headphones, earmuff headphones, earhook headphones, earplug headphones, or in-ear headphones. In particular, the headphone unit structure 100 of the utility model is small in size and has a rectangular small speaker, which is most suitable for combining the units to make in-ear headphones. When used, the sound outlet of the headphone is equipped with a silicone sleeve to fill the gap in the ear canal and create a closed listening environment similar to an earmuff, so that it has the characteristics of high resolution and excellent sound quality.

[0063] In application, when the voice coil 12 is connected to an electrical signal, the induced magnetic field interacts with the magnetic field generated by the magnet 22, causing the voice coil 12 to move up and down, causing the diaphragm 11 to emit sound. At the same time, because the other side of the diaphragm 11 is provided with a coil 35 with a reverse magnetic circuit, the effect is equivalent to having two drive units at the same time. Therefore, when the audio signal passes through, both sides will move at the same time but in opposite directions. This type of movement can produce a greater sound pressure level, which is very important for reproducing the details of music. It can increase the sound energy and improve the volume and clarity of the bass or mid- and high-range. In addition, because the two drive units move in opposite directions, their vibrations can offset each other, which can help reduce the resonance of the speaker and reduce distortion.

[0064] In addition, the rectangular diaphragm 11 of the utility model also has advantages in high-resolution applications. This design not only maximizes the area occupied by the diaphragm 11, but also enhances the sound pressure and presents a stronger bass. At the same time, it can also reduce the displacement of the driver unit while maintaining the sound pressure, thereby reducing distortion and improving the clarity of the human voice. This is very beneficial for music playback that requires high resolution, and can enhance the mid-frequency to make the human voice brighter and easier to identify.

[0065] Compared with the prior art, the advantages of the earphone monomer structure of the present invention are: the overall planning and design are simple and practical, based on the voice coil structure, and a dynamic iron type auxiliary structure is added to the middle part. The most significant feature is that the internal diaphragm 11 is changed into a rectangle, with a voice coil 12 on one side and a coil 35 of a reverse magnetic circuit on the other side, while the outside constitutes a small rectangular speaker with enhanced protection, so that the constituent monomer has a dynamic iron type enclosure, which is suitable for modularization and convenient production and use of large and small sizes, that is, it breaks through the shortcomings of the traditional circular voice coil structure, and at the same time has a push-pull output effect, which can greatly improve the high-resolution sound quality to meet the high demands of music lovers, professional musicians, recording engineers, DJs, etc. for sound quality, provide an excellent sound quality experience, or be used in professional music production and recording work, so that they can appreciate the details and richness of music more deeply and enjoy the excellent sound quality experience of high-resolution music.

[0066] In summary, the utility model is novel and practical and fully meets the patent requirements, and a new patent application is now filed. However, the above is only a preferred embodiment of the utility model, and it cannot be used to limit the scope of implementation of the utility model; therefore, all equivalent changes and modifications made according to the scope of the utility model patent application and the content of the utility model specification should fall within the scope covered by the utility model patent.
