With the expansion of memory capacity, the increase in network bandwidth, the enhancement of processor performance, and people's rising demands for quality of life, lossless music is becoming increasingly popular, leading to a growing demand for lossless music players. Traditional high-fidelity digital audio players often focus on decoding and amplifying audio signals in their design, but they fall short in terms of heat dissipation, shock protection, and portability. Specifically, players generate a lot of heat during prolonged operation; if this heat cannot be dissipated in time, it will affect the player's performance and stability, and even shorten its lifespan. At the same time, players are easily damaged by impacts during carrying and use, leading to damage to internal components and affecting sound quality. Furthermore, with the widespread use of mobile devices, users have placed higher demands on the portability of music players.

[0003] Regarding heat dissipation, traditional players often use simple heat sinks or fans, but these methods suffer from low heat dissipation efficiency and high noise levels, failing to meet the high heat dissipation performance requirements of high-fidelity digital audio players. In terms of impact protection, traditional players often lack effective protective measures, making them easily damaged when subjected to impacts. Therefore, those skilled in the art propose a solution for a high-fidelity digital audio player. Utility Model Content

The technical solutions of this utility model will be clearly and completely described below in conjunction with embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model.

[0028] Example 1: A high-fidelity digital audio player includes a player mechanism 1. A heat dissipation protective sleeve 2 is fixedly installed on the bottom surface of the player body 11 of the player mechanism 1. Operation buttons 13 are fixed to the rear side of the upper surface of the player body 11, and a display screen 14 is fixed to the front side. A central processing unit, memory, audio decoder / converter, and power amplifier are installed internally. A communication interface 12 is provided on the rear end face. The top edge of the heat-conducting plate 211 on the inner side of the heat dissipation protective sleeve 2 is fixedly connected to the bottom surface of the player body 11 by adhesive. The central area of ​​the upper surface is in contact with the heat-generating area on the bottom of the player body 11 by thermally conductive silicone grease. The space between the inner heat-conducting plate 211 and the outer rubber shell 214 is divided into multiple rectangular heat dissipation chambers by several fins 212. Cavities 213 are formed on the left and right sides. Two silicone strips 22 are filled in the cavities 213 to protect the left and right sides of the player body 11 from impacts. A connecting plate 23 is fixedly connected to the bottom surface of the inner heat-conducting plate 211. A U-shaped plastic strip 241 is fixed to the lower surface of the connecting plate 23. Several protrusions 242 are staggered and fixed to the inner surface of the U-shaped plastic strip 241. In use, the U-shaped plastic strip 241 is inserted into the pocket of pants or shirt. The protrusions 242 increase friction to prevent slippage. The heat generated by the player body 11 during operation is conducted to the fins 212 through the inner heat-conducting plate 211 and dissipated through the outer rubber shell 214. The silicone strip 22 protects the left and right sides of the player body 11 from bumps.

[0029] Example 2: In the player mechanism 1 of the high-fidelity digital audio player, a heat dissipation protective sleeve 2 is fixed to the bottom of the player body 11. The operation buttons 13 and the display screen 14 on the player body 11 are located on the rear and front sides of the upper surface, respectively. The internal components include a central processing unit, and there is a communication interface 12 at the rear. The inner heat-conducting plate 211 of the heat dissipation shell 21 is connected to the bottom of the player body 11 by adhesive and thermal grease. The fins 212 divide the middle section of the inner heat-conducting plate 211 and the outer rubber shell 214 into heat dissipation chambers, and the left and right cavities 213 are filled with silicone strips 22. The U-shaped plastic strip 241 of the pocket clip 24 is connected to the inner heat-conducting plate 211 through a connecting plate 23, and the protrusions 242 on the inner side of the U-shaped plastic strip 241 are staggered. When the player is used outdoors, the U-shaped plastic strip 241 is clipped to the side pocket of the backpack, the protrusion 242 prevents it from slipping, the heat is dissipated through the inner heat conduction plate 211, fins 212 and outer rubber shell 214, and the silicone strip 22 protects the player body 11.

[0030] Example 3: A heat dissipation protective cover 2 is installed at the bottom of the player mechanism 1 of a high-fidelity digital audio player. The player body 11 has operation buttons 13 and a display screen 14, and internal components such as a central processing unit. A communication interface 12 is located at the rear. The inner heat-conducting plate 211 of the heat dissipation rear shell 21 is connected to the bottom of the player body 11. Fins 212 divide the middle section into a heat dissipation chamber, and the left and right cavities 213 are filled with silicone strips 22. The U-shaped plastic strip 241 of the pocket clip 24 is fixed to the inner heat-conducting plate 211 via a connecting plate 23, and the inner protrusions 242 are staggered. When used indoors, the U-shaped plastic strip 241 is clipped into the opening of a pocket on a table. The protrusions 242 increase stability, and the heat generated by the player body 11 during operation is dissipated through the heat dissipation structure. The silicone strips 22 protect the sides of the body.

[0031] Based on the above-described preferred technical solution, the workflow of this technical solution is explained as follows:

[0032] The central processing unit starts running, reads audio data from the memory, and the audio decoder converts the read audio data into a digital audio signal suitable for playback. The power amplifier amplifies the analog signal and outputs it to the playback device. At the same time, the operation button 13 allows the user to perform operations such as play, pause, and switch tracks. The display screen 14 displays the playback status, track information, and other content in real time. The communication interface 12 on the rear end of the player body 11 can connect to external devices to realize data transmission and other functions. During operation, the player body 11 generates heat. At this time, the heat dissipation protective sleeve 2 begins to function. The top edge of the inner heat-conducting plate 211 of the heat dissipation back shell 21 is fixedly connected to the bottom surface of the player body 11 with adhesive. The central area of ​​the upper surface is in contact with the heat-generating area at the bottom of the player body 11 through thermal grease, which can quickly conduct the heat generated by the player body 11 to the inner heat-conducting plate 211. Several fins 212 between the inner heat-conducting plate 211 and the outer rubber shell 214 divide the space between them into multiple rectangular heat dissipation chambers. The heat is dissipated into the heat dissipation chambers through the fins 212 and then dissipated into the surrounding environment through the outer rubber shell 214, thus achieving the heat dissipation function.

[0033] The inner heat-conducting plate 211 and the outer rubber shell 214 form cavities 213 on their left and right sides, which are close to each other. Two silicone strips 22 are filled in the cavity 213. When the player body 11 is bumped from the left or right, the silicone strips 22 can act as a buffer to protect the left and right sides of the player body 11 from bumps. If it is necessary to fix the player in the pocket of pants or shirt, the pocket clip 24 comes into play. The bottom surface of the inner heat-conducting plate 211 is fixedly connected to the connecting plate 23, and the top surface of the U-shaped plastic strip 241 is fixedly connected to the bottom surface of the connecting plate 23. The U-shaped plastic strip 241 is inserted into the pocket of pants or shirt. Several protrusions 242 fixedly and interlaced on the inner surface of the U-shaped plastic strip 241 are interlaced to increase the friction with the pocket opening and prevent the player from slipping.

[0034] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
