Description

Technical Field

[0001] This application relates to the field of speaker technology, and more specifically, to an active heat dissipation speaker. Background Technology

[0002] As a core component of audio playback devices, speaker cooling has become a key technological focus in the industry's pursuit of high-fidelity sound quality and compact design. With the continuous increase in speaker power and the widespread adoption of portable devices, the demand for efficient cooling solutions is growing to support long-term stable operation and optimized sound quality. The industry is actively exploring innovative cooling technologies to adapt to high-performance audio applications such as home theaters and portable speakers, driving the development of cooling designs towards greater efficiency and lighter weight.

[0003] However, traditional speaker cooling solutions have significant drawbacks. Low heat dissipation efficiency is the core issue; the heat generated during speaker operation continuously accumulates within the sealed enclosure, unable to dissipate effectively. This heat accumulation directly affects the physical properties of the diaphragm material, causing it to soften or deform at high temperatures, resulting in sound distortion, frequency response shifts, and other sound quality degradation. It also accelerates the aging process of internal electronic components, shortening the device's lifespan. Existing cooling methods all have inherent flaws: while ventilation holes promote airflow, they compromise the enclosure's seal, leading to acoustic short circuits—abnormal leakage of sound energy from the holes, interfering with normal sound wave propagation paths and generating airflow noise; forced air cooling relies on fans for forced cooling, but the mechanical vibrations introduced by the fan resonate with the enclosure structure, causing additional noise that interferes with sound purity; while heat pipe technology can transfer heat, its installation alters the acoustic reflective surfaces inside the speaker, affecting sound diffusion and focusing characteristics; passive cooling relies on high thermal conductivity materials, but these materials have limited thermal conductivity, failing to meet the demands of high-power applications, and are also costly. These shortcomings are intertwined, which means that while traditional heat dissipation solutions improve heat dissipation, they inevitably sacrifice acoustic performance, making it impossible to achieve a balance between heat management and sound quality optimization.

[0004] There is currently no effective technical solution to the above problems. Utility Model Content

[0026] Please refer to Figures 1-3 Some embodiments of this application provide an active heat dissipation speaker, including: a shell 1, a sound-emitting unit 2, and a heat dissipation strip 3. The shell 1 has a first opening 13. The sound-emitting unit 2 is fixed inside the shell 1, and the sound-emitting side of the sound-emitting unit 2 is arranged facing the first opening 13. A second opening 14 is provided on one side of the shell 1. One end of the heat dissipation strip 3 is attached and fixed to the sound-emitting unit 2, and the other end passes through the second opening 14 and is attached and fixed to the outside of the shell 1, so as to transfer the heat generated by the sound-emitting unit 2 to the outside for active heat dissipation.

[0027] Specifically, the heat dissipation strip 3 refers to a flexible strip-shaped element used for heat conduction. It can be made of graphene, polymer-based thermally conductive composite materials, or ceramic fiber woven strips, such as strips filled with thermally conductive particles using polyimide film or alumina fiber reinforced strips. Its main purpose is to transfer heat from the sound-generating unit 2 to the external environment. Attachment and fixing refers to the method of establishing a tight connection between the heat dissipation strip 3 and the surface of the sound-generating unit 2 or the outer shell 1. This can be achieved using hot melt adhesive, double-sided tape, or mechanical pressing, such as using acrylic adhesives or silicone pressure-sensitive tape. Its main purpose is to ensure the continuity of the heat conduction path and maintain the enclosure's airtightness. The second opening 14 refers to a channel structure on the outer shell 1 specifically designed for the heat dissipation strip 3. It can be achieved using stamped holes or laser-cut slits, such as circular through holes or rectangular slots. Its main purpose is to allow the heat dissipation strip 3 to pass through without compromising the overall integrity of the enclosure.

[0028] More specifically, this embodiment employs a structural design where one end of the heat dissipation strip 3 is attached and fixed to the sound-generating unit 2, and the other end passes through the second opening 14 and is attached and fixed to the outside of the outer casing 1. This design establishes a direct heat conduction path while maintaining the airtightness of the enclosure. This avoids acoustic short circuits caused by ventilation holes, vibration interference introduced by fans, and damage to the acoustic reflective surface caused by heat pipes in traditional heat dissipation solutions. Consequently, it solves the problems of low heat dissipation efficiency leading to sound quality degradation and component aging, while ensuring the long-term stability of the equipment. Specifically, this design allows the heat generated by the sound-generating unit 2 to be absorbed by the heat dissipation strip 3 and conducted to the external environment, achieving active heat dissipation without sacrificing the acoustic performance of the enclosure.

[0029] More specifically, this actively cooled speaker achieves efficient heat dissipation by constructing a direct heat conduction path. Specifically, the outer shell 1 has a first opening 13, and the speaker unit 2 is fixed inside the outer shell 1 with its sound-emitting side facing the first opening 13 to ensure that the sound output direction meets acoustic design requirements. A second opening 14 is provided on one side of the outer shell 1. One end of a heat dissipation strip 3 is attached and fixed to the speaker unit 2, forming a tight thermal contact interface to efficiently absorb the heat generated during sound production. The other end of the heat dissipation strip 3 passes through the second opening 14 and is attached and fixed to the outside of the outer shell 1, transferring heat to the external environment for heat dissipation. Simultaneously, this attachment and fixing method seals the second opening 14, preventing air leakage and acoustic short circuits.

[0030] Therefore, the active heat dissipation speaker in this embodiment of the application directly attaches the heat dissipation strip 3 to the sound-generating unit 2 and extends to the outside of the outer shell 1, so as to efficiently transfer heat to the environment to achieve active heat dissipation. It solves the problem of heat accumulation without damaging the sealing of the cabinet or introducing additional noise sources. It has the advantages of improving heat dissipation efficiency, effectively preventing the sound quality deterioration and component aging of the sound-generating unit 2 due to heat accumulation, while maintaining the sealing of the speaker cabinet and avoiding the sacrifice of acoustic performance in traditional heat dissipation solutions.

[0031] In some preferred embodiments, the housing 1 includes a front cover 11 and a rear cover 12, with a first opening 13 located on the front cover 11 and the rear cover 12 snapped onto the front cover 11 to surround the sound-generating unit 2.

[0032] Specifically, the front cover 11 and the rear cover 12 provide a stable acoustic support foundation for the sound-generating unit 2. In practical applications, the rear cover 12 is snapped onto the front cover 11, which means that the rear cover 12 is quickly connected to the front cover 11 through an elastic snap mechanism. This can be achieved by using plastic elastic snaps, metal spring snaps, or magnetic snaps, etc. The purpose is to complete the assembly without additional fasteners. The uniform pressure distribution ensures a tight fit between the front cover 11 and the rear cover 12, effectively blocking the airflow leakage path.

[0033] Through the above solution, this application effectively solves the problems of difficulty in accurately controlling the position of the first opening 13 and insufficient sealing of the enclosure, significantly suppresses the acoustic short circuit phenomenon and the generation of airflow noise, simplifies the assembly process and avoids the formation of structural gaps, thereby improving the sound quality stability and equipment reliability.

[0034] In some preferred embodiments, a first groove 121 is provided on one side of the rear cover 12, and a second groove 111 is provided on one side of the front cover 11 opposite to the first groove 121, forming a second opening 14 between the first groove 121 and the second groove 111.

[0035] Specifically, when the rear cover 12 and the front cover 11 are fixed by the snap, the two slots naturally align and form a complete second opening 14. This opening provides a stable and reliable path for the heat dissipation strip 3 to pass through, while effectively preventing external airflow from interfering with the operation of the sound-generating unit 2, and avoiding acoustic short circuits and the generation of airflow noise.

[0036] As a specific implementation method, the solution of this application is implemented as follows: the first slot 121 of the rear cover 12 is a U-shaped groove structure, and the second slot 111 of the front cover 11 is a matching U-shaped groove structure. When the rear cover 12 and the front cover 11 are fixed by a buckle, the two U-shaped grooves are precisely aligned and form a rectangular channel as the second opening 14. The heat dissipation strip 3 passes through the channel to achieve heat transfer.

[0037] Through the above technical solution, this application effectively solves the problem of insufficient sealing caused by the inaccurate position of the second opening 14, prevents acoustic short circuit and airflow noise, and ensures the sound quality stability and heat dissipation efficiency of the speaker during long-term operation.

[0038] In some preferred embodiments, the heat dissipation strip 3 is fixed to the second opening 14 by dispensing adhesive sealant.

[0039] Specifically, the adhesive sealing fixation can be understood as using the fluidity and adhesion properties of the adhesive material to form a continuous and dense sealing layer between the heat dissipation strip 3 and the edge of the second opening 14. It can be achieved by using materials such as epoxy resin, silicone or polyurethane adhesive through automated adhesive dispensing equipment. The purpose is to effectively fill the tiny gaps generated when the heat dissipation strip 3 passes through the second opening 14, avoid the air leakage path caused by traditional mechanical fixing methods, and thus maintain the integrity of the acoustic environment of the enclosure.

[0040] More specifically, the solution of this application applies adhesive material to the contact interface between the heat dissipation strip 3 and the second opening 14, utilizes the fluidity of the material to fully wet the gap and form an elastic sealing layer after curing. This sealing layer blocks the airflow path between the inside and outside of the enclosure, while adapting to the slight displacement of the heat dissipation strip 3 caused by thermal expansion and contraction, ensuring that heat is continuously transferred to the outside without damaging the acoustic seal, thereby synergistically optimizing the heat dissipation function and acoustic performance.

[0041] In some preferred embodiments, a first adhesive groove 122 is provided on the outer side of the first groove portion 121, and a second adhesive groove 112 is provided on the outer side of the second groove portion 111. The heat dissipation strip 3 is sealed and fixed on the second opening 14 by applying adhesive in the first adhesive groove 122 and the second adhesive groove 112.

[0042] Specifically, the first dispensing groove 122 refers to a groove structure provided on the outside of the first groove opening 121 of the rear cover 12 of the outer shell 1 for accommodating dispensing material. Its purpose is to constrain the distribution range of the dispensing material, prevent material overflow or uneven distribution during the dispensing process, thereby ensuring uniform adhesive layer thickness and improving adhesive strength. The second dispensing groove 112 refers to a symmetrical groove structure provided on the outside of the second groove opening 111 of the front cover 11 of the outer shell 1. It can adopt the same or different cross-sectional shape as the first dispensing groove 122. Its purpose is to provide another dispensing area so that the heat dissipation strip 3 is subjected to balanced force during the fixing process, reducing the risk of connection failure caused by local stress concentration.

[0043] More specifically, the first dispensing groove 122 and the second dispensing groove 112 are respectively disposed on the outside of the first groove opening 121 and the second groove opening 111. When the dispensing material is filled into the groove, the groove structure forms a physical constraint on the material, preventing the material from shifting or overflowing during the curing process. As a result, the connection interface between the heat dissipation strip 3 and the outer shell 1 is tightly and permanently fixed, which maintains the continuity of the heat dissipation path and ensures the acoustic sealing of the inside of the box, thereby solving the dual problems of loose fixing and poor sealing in the dispensing process.

[0044] In some preferred embodiments, the outer casing 1 has a heat dissipation plane 15 on the side opposite to the first opening 13, and the other end of the heat dissipation strip 3 includes a transition strip 32 passing through the second opening 14, a bent strip 33 that fits against the side of the outer casing 1, and a heat dissipation strip 34 that is attached and fixed to the heat dissipation plane 15.

[0045] Specifically, the heat dissipation plane 15 refers to the flat area on the side of the outer shell 1 away from the first opening 13, which is used to enhance heat conduction. It can be implemented using a continuous planar structure, and its purpose is to provide a uniform heat distribution interface to expand the effective heat dissipation area. The transition section 32 refers to the connecting part of the heat dissipation strip 3 passing through the second opening 14. Its purpose is to reduce the mechanical stress on the heat dissipation strip 3 at the edge of the opening and maintain the continuity of the heat conduction path. The bending section 33 refers to the bent part of the heat dissipation strip 3 that fits tightly against the side of the outer shell 1. It can be implemented using a single bending structure or a multi-level bending structure. Its purpose is to adapt to the geometric contour of the outer shell 1 to maximize the contact area and eliminate air gaps. The heat dissipation section 34 refers to the terminal heat dissipation part attached and fixed on the heat dissipation plane 15. It can be implemented using a rectangular strip structure or a trapezoidal extended structure. Its purpose is to use the flat surface to accelerate the dissipation of heat to the environment.

[0046] Specifically, the solution of this application provides a flat and continuous heat conduction interface through a heat dissipation plane 15 located on the side of the outer shell 1 facing away from the first opening 13. The transition section 32 of the heat dissipation strip 3 smoothly exits through the second opening 14, avoiding stress concentration at the opening edge. The bent section 33 closely fits the side of the outer shell 1, eliminating geometric gaps and making full use of the side heat dissipation space. The heat dissipation strip section 34 is fixed to the heat dissipation plane 15, forming a large area of ​​thermal contact. The above structures work together to conduct heat from the sound-generating unit 2 through the heat dissipation strip 3, through the transition section 32 and the bent section 33, to the heat dissipation strip section 34, and finally efficiently dissipates it to the external environment through the heat dissipation plane 15, thereby optimizing the heat conduction path and improving the overall heat dissipation efficiency.

[0047] In some preferred embodiments, one end of the heat dissipation strip 3 includes a heat absorption section 31 attached and fixed to the back of the sound-generating unit 2, and the surface area of ​​the heat dissipation strip section 34 is larger than the surface area of ​​the heat absorption section 31.

[0048] Specifically, in practical applications, the heat-absorbing section 31 refers to the part that directly contacts the back of the sound-generating unit 2 to capture heat energy, with the aim of efficiently absorbing heat from the concentrated heat source area.

[0049] More specifically, the solution of this application focuses on heat absorption efficiency through the small-area design of the heat-absorbing section 31, ensuring that heat is quickly transferred from the back of the sound-generating unit 2 to the heat dissipation band 3; at the same time, the large-area design of the heat dissipation band section 34 enhances heat dissipation capacity, allowing the transferred heat to be evenly diffused over a larger surface area, avoiding local heat accumulation, thereby forming an efficient heat transfer path. This area ratio optimization is based on the principles of heat conduction and convection heat dissipation, enabling a dynamic balance between heat absorption and heat dissipation processes, overcoming the defects of heat transfer mismatch in the original structure.

[0050] In some preferred embodiments, the heat dissipation plane 15 is provided with a receiving groove 151, and the heat dissipation strip 34 is attached and fixed in the receiving groove 151, with its outer side flush with the top surface of the heat dissipation plane 15.

[0051] Specifically, the receiving groove 151 refers to the recessed structure on the heat dissipation plane 15, which aims to provide embedding space to reduce the thermal resistance of the heat conduction interface. The heat dissipation strip 34 is attached and fixed in the receiving groove 151, which can be understood as fixing the heat dissipation strip 34 in the groove by applying glue, adhesive or hot melt glue. The purpose is to use the constraint of the groove boundary to achieve all-round support and avoid the risk of loosening caused by vibration. In practical applications, the outer surface being flush with the top surface of the heat dissipation plane 15 specifically means that the outer surface of the heat dissipation strip 34 is kept on the same plane as the surface of the heat dissipation plane 15. The purpose is to maximize the contact area with the outside air to enhance the natural convection heat dissipation effect, while eliminating the negative impact of the protruding part on the product appearance and durability.

[0052] Specifically, the solution of this application provides an embedding space for the heat dissipation strip 34 through the receiving groove 151 structure of the heat dissipation plane 15, reducing the interfacial thermal resistance during the heat conduction process and ensuring a continuous and stable heat transfer path. At the same time, the fixing method of the heat dissipation strip 34 in the receiving groove 151 effectively suppresses the displacement caused by speaker vibration or external impact, maintaining the durability of heat conduction. In addition, the design of the outer side being flush with the top surface of the heat dissipation plane 15 optimizes the flatness of the heat dissipation surface, improves the efficiency of heat transfer to the air, and takes into account the integrity of the product appearance.

[0053] In some preferred embodiments, the sound-generating monomer 2 is sealed and fixed to the first opening 13.

[0054] Specifically, sealing and fixing refers to forming a completely airtight connection at the interface between the sound-generating unit 2 and the first opening 13. This can be achieved using silicone sealing rings, epoxy resin sealant, or rubber gaskets. The purpose is to eliminate air leakage paths and prevent acoustic short circuits.

[0055] More specifically, the solution of this application seals and fixes the sound-generating unit 2 on the first opening 13, so that the sound-generating unit 2 and the interface of the outer shell 1 form an airtight connection, effectively blocking the air leakage path; in the active heat dissipation structure, the heat dissipation strip 3 does not damage the integrity of the acoustic cavity when transferring heat, thereby maintaining the stability of the diaphragm vibration and avoiding sound quality degradation caused by airflow disturbance.

[0056] In some preferred embodiments, the heat dissipation strip 3 is a graphene heat dissipation strip, an artificial graphite film heat dissipation strip, a metal heat dissipation strip, or an insulating ceramic heat dissipation strip.

[0057] Specifically, graphene heat sinks refer to heat dissipation components made using the high thermal conductivity of graphene materials, which can be achieved by preparing single-layer or multi-layer graphene films using chemical vapor deposition. Artificial graphite film heat sinks can be understood as flexible materials formed by processing polyimide films through high-temperature graphitization processes, which can be achieved by producing graphite films using roll-to-roll processes, aiming to balance thermal conductivity and cost. Metal heat sinks specifically refer to heat sinks made of high thermal conductivity metal materials, which can be achieved using copper or aluminum sheet structures, aiming to enhance heat dissipation efficiency under high-power operating conditions. Insulating ceramic heat sinks, in practical applications, refer to heat dissipation components made of ceramic matrix composite materials, which can be achieved using alumina ceramic substrates, aiming to provide heat dissipation while ensuring electrical insulation.

[0058] More specifically, the solution of this application uses a heat dissipation strip 3 as a heat conduction medium. One end is attached to and fixed to the sound-generating unit 2 to absorb heat, and the other end passes through the second opening 14 of the outer shell 1 and is attached to the outside of the outer shell 1 for heat dissipation. Graphene material is selected to take advantage of its ultra-high thermal conductivity, which significantly accelerates the transfer of heat from the sound-generating unit 2 to the external environment; artificial graphite film material reduces manufacturing costs while maintaining good thermal conductivity; metal material enhances high-power heat dissipation with its excellent thermal conductivity; and insulating ceramic material provides an efficient heat dissipation path while achieving electrical insulation to prevent short-circuit risks. These materials work synergistically with the structural arrangement of the heat dissipation strip 3 to ensure efficient heat transfer to the outside, avoid heat accumulation inside the enclosure from interfering with the physical properties of the diaphragm material, and thus maintain sound quality stability and equipment reliability.
