Description

Technical Field

[0001] This utility model relates to the field of loudspeaker technology, and in particular to a loudspeaker with enhanced heat dissipation. Background Technology

[0002] Currently, with the improvement of people's living standards, the requirements for audio-visual systems are also increasing. Loudspeakers are a common audio output device that produces sound by causing a paper cone to vibrate due to the force exerted on a current-carrying coil in a magnetic field. During prolonged use, the speaker coil often generates a lot of heat. If heat cannot be dissipated effectively and in a timely manner, excessively high temperatures can lead to a series of problems such as voice coil decoupling, magnetic circuit delamination, and magnet demagnetization, affecting speaker performance. Excessive temperatures can also cause changes in the shape of heat-sensitive materials such as the speaker frame, leading to deformation or even damage, which will affect the normal operation and lifespan of the speaker. Therefore, a new type of loudspeaker is needed. Utility Model Content

[0003] In view of this, one of the technical problems to be solved by this utility model is to provide a speaker with enhanced heat dissipation.

[0004] This utility model provides a loudspeaker with enhanced heat dissipation, comprising: a dust cap, a cone, a voice coil, a positioning support, a frame, a welding plate, a pad, an upper clamp, a magnet, and a T-iron; the T-iron is provided with a first central through hole as a heat dissipation channel for dissipating the heat generated by the voice coil.

[0005] According to one embodiment of the present invention, the magnet is further disposed between the upper clamping plate and the T-iron, and the upper clamping plate, the magnet and the T-iron are combined into a magnetic circuit device by adhesive bonding.

[0007] According to one embodiment of the present invention, the waterproof and breathable membrane is further provided with a second central through hole, and the diameter of the first central through hole is the same as the diameter of the second central through hole.

[0008] According to one embodiment of the present invention, the diameter of the sound-absorbing foam is 1.4 times the diameter of the first central through hole.

[0009] According to one embodiment of the present invention, the voice coil is further fixed to the top of the positioning support plate by adhesive bonding; the solder pad is soldered to the driving circuit lead of the voice coil.

[0017] The present invention will now be described more fully with reference to the accompanying drawings, which illustrate exemplary embodiments of the present invention. The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. The technical solutions of the present invention will now be described in various aspects with reference to the figures and embodiments.

[0018] like Figure 1 As shown, this utility model provides a loudspeaker with enhanced heat dissipation, including: a dust cap 1, a cone 2, a voice coil 3, a positioning support 4, a frame 5, a welding plate 6, a padding edge 7, an upper clamping plate 8, a magnet 9, and a T-iron 10, etc. Figure 2 As shown, the T-iron 10 is provided with a first central through hole 101, which serves as a heat dissipation channel for dissipating the heat generated by the voice coil.

[0019] The dust cap 1, cone 2, voice coil 3, positioning support 4, frame 5, welding plate 6, padding 7, upper clamp 8, magnet 9, and T-iron 10 can be assembled in various ways to form a speaker structure. For example, the voice coil 3 is glued to the top of the positioning support 4; the welding plate 6 is soldered to the drive circuit leads of the voice coil 10. The magnet 9 is located between the upper clamp 8 and the T-iron 10, and the upper clamp 8, magnet 9, and T-iron 10 are glued together to form a magnetic circuit device. The material of the T-iron 10 may include low carbon steel, etc.

[0020] The lifespan and power handling capacity of a loudspeaker are primarily limited by the voice coil. The voice coil is like the heart of the loudspeaker; damage to the voice coil will directly lead to the loudspeaker's cessation of operation. The greater the power of the loudspeaker, the greater the heat generated, causing the voice coil temperature to rise. If the voice coil cannot be properly cooled, it will burn out when the voice coil material reaches its limit. Therefore, helping to cool the voice coil is particularly important.

[0021] This invention relates to a loudspeaker with enhanced heat dissipation. By designing heat dissipation holes on the T-iron, it increases the heat dissipation channels. During the loudspeaker's operation, the vibration of the cone pushes the air, which can directly and effectively dissipate the heat generated by the voice coil, keeping the loudspeaker's operating temperature within a suitable range. The T-iron material can be low-carbon steel, etc., which has good thermal conductivity and high-temperature resistance. Under the same conditions, it reduces weight, and the heat dissipation structure is simple, easy to manufacture, and low in cost.

[0022] In some embodiments, the speaker further includes: sound-absorbing foam 11 and waterproof and breathable membrane 12; the sound-absorbing foam 11 is glued to the bottom of the T-iron 10, and the waterproof and breathable membrane 12 is glued to the bottom of the sound-absorbing foam 11.

[0023] Adding heat dissipation holes to the T-shaped iron creates airflow channels, resulting in additional airflow noise, such as whistling (wheezing noise) caused by excessively small openings. This noise begins when the airflow velocity reaches 5% or more of the air velocity, and becomes noticeable when it reaches 10% of the air velocity. Adding sound-absorbing foam to absorb noise, such as... Figure 3 As shown, the sound-absorbing foam 11 can be made of PU or other materials. The sound-absorbing foam 11 made of PU material can effectively absorb noise and solve the problem of airflow noise.

[0024] Because the addition of heat dissipation holes to the T-iron exposes the internal magnetic circuitry, external debris, dust, and rainwater can enter the magnetic circuitry through these holes. Therefore, a waterproof and breathable membrane 12 is added to the speaker. Figure 4As shown. The waterproof and breathable membrane 12 can be made of materials such as PBT; the central pore portion of the waterproof and breathable membrane 12 is waterproof and breathable, and the periphery of the waterproof and breathable membrane 12 adopts a peel-off paper adhesive design, which is easy to tear and stick, and can be tightly attached to the bottom of the T-iron. The surface of the waterproof and breathable membrane 12 is matte black, which satisfies aesthetic requirements while being practical.

[0025] like Figure 4 As shown, the waterproof and breathable membrane 12 has a second central through-hole 121, and the diameter of the first central through-hole 101 is the same as the diameter of the second central through-hole 121. Adhesive 122 is provided on the edge of the waterproof and breathable membrane 12. The diameter of the sound-absorbing foam 11 is 1.4 times the diameter of the first central through-hole 101. For example, if the aperture of the T-iron is φA, then the outer diameter φB of the sound-absorbing foam 11 is equivalent to increasing φA by 2 / 5, and the second central through-hole 121 φC of the waterproof and breathable membrane 12 has the same size as φA.

[0026] This invention relates to a speaker with enhanced heat dissipation. By adding heat dissipation holes to the T-iron and incorporating sound-absorbing foam and a waterproof and breathable membrane, it not only enhances heat dissipation and extends the speaker's lifespan but also reduces the weight of the T-iron, saving costs. The speaker's heat dissipation solution is integrated with its appearance design, ensuring both effective heat dissipation and aesthetic appeal. This invention features a simple structure, is easy to manufacture, and has low cost. This speaker with enhanced heat dissipation has excellent market application prospects and is well-received by customers.

[0027] The description of this utility model is given for illustrative and descriptive purposes only, and is not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical application of the utility model, and to enable those skilled in the art to understand the utility model and design various embodiments with various modifications suitable for a particular purpose.
