Abstract
Description
Technical Field
[0001] This utility model relates to the field of loudspeaker structure technology, specifically to a hollow open-structure loudspeaker. Background Technology
[0002] Traditional dynamic speakers typically have a sealed structure without any openings in the center. This structure seals the ear shut during use, isolating the user from the outside environment and hindering communication. Furthermore, prolonged wear can damage the ears and is detrimental to ear hygiene, increasing the likelihood of ear canal infections. Utility Model Content
[0003] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: a hollow open structure speaker, including a cone, a U-cup, a voice coil and a magnet arranged sequentially from the outside to the inside. The cone, U-cup, voice coil and magnet are all hollow annular structures. The opening side of the cone and U-cup is covered with a diaphragm. A wire bonding plate is also provided on the side of the cone away from the diaphragm.
[0004] Furthermore, the cone has an L-shaped cross-section, the U-cup has a U-shaped cross-section, the voice coil is disposed in the U-shaped cavity of the U-cup, and the magnet is disposed on the side of the U-cup away from the cone.
[0005] Furthermore, the bottom surface of the basin is provided with several tuning holes along the axial direction.
[0006] Furthermore, the hollow structure at the center of the magnet is square or circular in shape.
[0007] The advantages of this utility model compared with the prior art are as follows:
[0008] The hollow annular structure of the cone, U-cup, voice coil, and magnet in this invention forms an air resonant cavity. Sound waves are amplified through the cavity resonance and diffused in multiple directions through the tuning hole at the bottom of the cone, achieving a more natural sound field distribution. Compared with traditional closed-back speakers, it can improve the sound field width, reduce sound reflection noise in the cavity, and significantly enhance the clarity of mid-to-high frequencies.
[0009] The hollow magnet design ensures a balanced low, mid, and high frequency response without reducing the magnetic flux. The low frequency is enhanced by the resonant cavity, and the high frequency is reduced by the open structure, thus widening the frequency response range to 20Hz-20kHz and eliminating the "mid-frequency depression" problem of traditional dynamic speakers.
[0010] This invention can serve as a core component of headphones, avoiding the need for a completely closed soundproof design without compromising sound quality. It allows for harmonious coexistence with the surrounding environment without isolating the external environment. At the same time, the open structure avoids the problem of ear pressure accumulation in closed headphones, improving long-term wearing comfort. Additionally, air circulation in the ear canal reduces the risk of bacterial growth. Attached Figure Description

[0023] Example:
[0024] Combined with appendix Figure 1-7 This embodiment discloses a hollow open-structure speaker, including a cone 1, a U-cup 2, a voice coil 3, and a magnet 4 arranged sequentially from the outside in. The cone 1, U-cup 2, voice coil 3, and magnet 4 are all hollow annular structures. A diaphragm 5 covers the open side of the cone 1 and U-cup 2. A bonding plate 6 is also provided on the side of the cone 1 away from the diaphragm 5. The hollow structure in the magnet 4 can be square. Figure 1 ) or round ( Figure 5 ).
[0025] The cone 1 has an L-shaped cross-section, the U-cup 2 has a U-shaped cross-section, the voice coil 3 is disposed within the U-shaped cavity 201 of the U-cup 2, and the magnet 4 is disposed on the side of the U-cup 2 away from the cone 1. Several tuning holes 101 are axially arranged on the bottom surface of the cone 1. In use, different tuning papers can be fitted onto the tuning holes to obtain different sound qualities.
[0026] In practice, after the voice coil 3 is energized, it moves vertically in the magnetic field of the U-cup 2, driving the diaphragm 5 to produce sound directly. The hollow ring structure of the basin 1, U-cup 2, voice coil 3, and magnet 4 forms an air resonant cavity. The sound waves are amplified through the cavity resonance and diffused in multiple directions through the tuning hole at the bottom of the basin 1, achieving a more natural sound field distribution.
[0027] Traditional dynamic speakers lack a hollow center. This embodiment utilizes a hollow resonant cavity and opening design to efficiently couple the initial sound waves into the air, achieving sound amplification and directional propagation. Furthermore, by making the magnets hollow, the magnetic flux is increased. Depending on specific needs, the magnets can be circular, square, or other shapes. Headphones made using this speaker have completely open ear sections, ensuring no isolation from the external environment even without removing the headphones, facilitating communication. Simultaneously, the open-back design does not completely enclose the ears, preventing damage even after prolonged use. It maintains ear hygiene, avoids ear canal blockage leading to infection, and enhances patient comfort.
[0028] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. In addition, the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here. The contents not described in detail in this specification belong to the prior art known to those skilled in the art.
[0029] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
