Description

Technical Field

[0001] This utility model relates to the field of audio equipment technology, specifically a portable audio decoding adapter. Background Technology

[0002] In the early days, audio devices were relatively simple; for example, traditional Walkmans primarily output signals through analog audio interfaces. With the development of digital audio technology, various digital audio formats such as MP3, AAC, and FLAC emerged in large numbers. At the same time, audio playback devices have become increasingly diversified, including smartphones, tablets, laptops, and professional audio players.

[0003] Some existing audio decoding devices are bulky and inconvenient to carry and use, which limits users' ability to enjoy high-quality audio in mobile scenarios. Utility Model Content

[0004] The purpose of this invention is to provide a portable audio decoding adapter, which has the advantages of small size and easy portability, and solves the problem that current audio decoding devices are large in size and inconvenient to carry and use.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a portable audio decoder adapter, comprising a housing, wherein the housing is a hollow cavity structure with an opening on one side, and an adapter body is inserted and installed inside the housing. A cover plate is provided at the opening of the housing, and a through groove is provided on the cover plate. A limiting plate for insertion into the housing is provided on the side of the cover plate facing the housing. The adapter body includes a decoder circuit board, and two mutually perpendicular input interfaces and output interfaces are provided at the top of the decoder circuit board. The input interfaces are embedded in the through groove, and the output interfaces are embedded in the limiting plate. Both the housing and the cover plate are provided with sealing mechanisms that respectively block the input interfaces and the output interfaces.

[0006] Preferably, the outer shell has an inclined pull-out surface on the side away from the cover plate, and a recessed groove on the top side of the outer shell, and a limiting groove for the insertion of the limiting plate is provided on the side of the outer shell.

[0007] Preferably, each of the sealing mechanisms includes a slide plate, one end of which is vertically provided with a connecting plate, and the other end of which is slidably mounted with a sliding frame, and two sliders are symmetrically provided at the end of the slide plate that extends into the sliding frame.

[0008] Preferably, both sliders are square, and the sides of the sliders are parallel to the sides of the slide plate.

[0009] Preferably, a circular plate is provided at the end of the connecting plate away from the slide plate, and a sealing plug is provided on the side of the circular plate facing the outer shell.

[0010] Preferably, the sliding frame is a plate-shaped structure with a U-shaped vertical cross section, and two convex plates are symmetrically arranged at one end of the sliding frame facing the slide plate. The sliding frame is symmetrically provided with sliding grooves for the slider to slide. A torsion column is rotatably installed in each of the two convex plates. Both torsion columns are circular columnar structures, and a fitting groove for the slider to fit into is provided on the adjacent side of the two torsion columns. The fitting groove is connected to the sliding groove.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model comprises an audio decoding adapter consisting of a shell, an adapter body, and a cover plate. The portable audio decoding adapter has a compact rectangular shape, making it easy to carry. Its shell is made of high-strength, lightweight metal material, such as aluminum alloy, which ensures structural strength and facilitates heat dissipation. Its internal circuitry includes a high-performance audio decoding chip that supports decoding of multiple audio formats and features low power consumption and high fidelity. The chip is connected to the input / output interface through optimized circuit wiring to reduce signal interference.

[0013] 2. This utility model, by setting up a sliding plate, connecting plate, circular plate, sealing plug, slider, sliding frame, protruding plate, sliding groove, torsion post, and fitting groove, uses a sealing plug on the circular plate to embed into the outer shell, sealing the interface of the outer shell. This effectively prevents dust from entering the adapter body and avoids dust affecting the connection stability. In use, the sealing plug on the circular plate is pulled out from the outer shell. When pulled out, the slider slides in the sliding groove until the slider slides into the fitting groove opened in the torsion post. The sliding plate is rotated around the axis of the torsion post to remove the circular plate from the interface of the outer shell. This allows for quick sealing and unsealing of the input and output interfaces of the adapter, making it quite practical. Attached Figure Description
