Description

Technical Field

[0001] This utility model relates to loudspeakers, specifically to a loudspeaker. Background Technology

[0002] A loudspeaker is a transducer that converts electrical signals into sound signals, and its performance has a significant impact on sound quality. Temperature is a major factor affecting loudspeaker performance. Loudspeakers generate heat when operating at high frequencies; higher temperatures have a greater negative impact on the magnetic field, and can even cause irreversible damage.

[0003] Traditional speaker cooling methods rely on the metal itself to conduct heat, absorbing internal heat and then dissipating it naturally. This cooling method is often slower than the heating speed, causing the temperature to accumulate, affecting the speaker's magnetic field and thus its performance, resulting in poor sound reproduction. Utility Model Content

[0004] The primary objective of this invention is to overcome the shortcomings of the existing technology by providing a loudspeaker. This loudspeaker can reduce the effects of temperature, thus ensuring its performance.

[0005] The objective of this utility model is achieved through the following technical solution: This loudspeaker includes a mounting shell, a loudspeaker body, a cooling chip, heat dissipation fins, a cooling fan, and a controller. One end of the mounting shell is fixed to the rear end of the loudspeaker body. The cooling chip is located inside the mounting shell, and the cold end of the cooling chip is connected to the rear end face of the loudspeaker body. The heat dissipation fins are connected to the hot end of the cooling chip. The cooling fan is mounted at the other end of the mounting shell. The cooling chip is connected to the controller.

[0006] Preferably, the mounting housing is cylindrical, and the sidewall of the mounting housing is provided with a plurality of evenly distributed strip-shaped heat dissipation holes.

[0007] Preferably, the heat dissipation fins include a base plate and multiple fins. One end of the base plate is connected to the hot end of the cooling plate through thermally conductive adhesive. One end of each fin is fixed to the other end of the base plate, and all fins are evenly distributed.

[0008] Preferably, the cooling fan is mounted on the mounting housing via a mounting bracket.

[0009] Preferably, the speaker further includes a temperature sensor mounted on the mounting housing for detecting the temperature of the speaker body.

[0010] Preferably, the distance between the cooling fan and the cooling fins is 0mm to 30mm.

[0011] This invention has the following advantages over the prior art:

[0012] This invention features a cooling plate on the back of the speaker body. The cooling plate generates heat to neutralize the heat generated during speaker operation, thereby preventing the internal temperature of the speaker from becoming too high. This ensures that the speaker operates in a suitable temperature environment, reduces the impact of internal temperature rise on speaker performance, and ensures sound fidelity.

Detailed Implementation

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0020] like Figure 1 , Figure 2 and Figure 3 The speaker shown includes a mounting housing, a speaker body, a cooling chip, heat dissipation fins, a cooling fan, and a controller. One end of the mounting housing is fixed to the rear end of the speaker body. The cooling chip is located inside the mounting housing, and the cold end of the cooling chip is connected to the rear end face of the speaker body. The heat dissipation fins are connected to the hot end of the cooling chip. The cooling fan is mounted at the other end of the mounting housing. The cooling chip is connected to the controller.

[0021] Specifically, the heat generated by the speaker during operation causes the internal temperature of the speaker body to gradually rise. When the temperature set by the controller is reached, the controller activates the cooling coil. The cooling energy generated by the cold end of the cooling coil quickly neutralizes the heat inside the speaker body, ensuring that components such as the magnets inside the speaker body remain in a suitable temperature environment, thus ensuring the speaker maintains good performance and continuous operation. Simultaneously, to ensure good cooling effect of the cooling coil, heat dissipation fins are connected to the hot end of the cooling coil using thermally conductive adhesive. A cooling fan is installed above the heat dissipation fins, allowing the heat generated by the hot end of the cooling coil to be quickly dissipated, ensuring the cooling effect of the cold end of the cooling coil and further improving the cooling effect of the cooling coil on the speaker body. To ensure optimal speaker performance, a silent cooling fan is used.

[0022] like Figure 5 As shown, the mounting housing is cylindrical, and its sidewalls are provided with multiple evenly distributed strip-shaped heat dissipation holes. The overall cylindrical shape of the mounting housing matches the rear cross-sectional profile of the speaker body, giving the entire speaker a compact and aesthetically pleasing appearance. The strip-shaped heat dissipation holes on the sidewalls of the mounting housing provide excellent ventilation, ensuring that the heat absorbed by the heat dissipation fins is quickly dissipated, thereby cooling the hot end of the cooling element.

[0023] like Figure 4 As shown, the heat dissipation fins include a base plate and multiple fins. One end of the base plate is connected to the hot end of the cooling fin via thermally conductive adhesive. One end of each fin is fixed to the other end of the base plate, and all fins are evenly distributed. Specifically, in this embodiment, the fins are all cylindrical, and multiple fins are evenly spaced to ensure that there is as much contact surface between the fins and the air as possible, thereby improving the heat dissipation effect.

[0024] The cooling fan is mounted on the mounting housing via a mounting bracket. The distance between the cooling fan and the heat dissipation fins is 0–30 mm. In this embodiment, the distance between the cooling fan and the upper end face of the heat dissipation fins is 5 mm. The cooling fan is mounted in an appropriate position via the mounting bracket to ensure its working performance, allowing air to quickly enter the mounting housing from above the cooling fan, pass through the heat dissipation fins, and then exit from the strip-shaped heat dissipation holes. This allows the lower-temperature air to quickly absorb the heat from the heat dissipation fins, thereby improving the heat dissipation effect.

[0025] The speaker also includes a temperature sensor mounted on the mounting housing to detect the temperature of the speaker body. Real-time monitoring of the speaker body temperature using this sensor provides a reliable basis for the operation of the cooling element and allows users to understand the speaker's real-time status.

[0026] The above-described specific embodiments are preferred embodiments of this utility model and are not intended to limit this utility model. Any other changes or equivalent substitutions made without departing from the technical solution of this utility model are included within the protection scope of this utility model.
