Description

Technical Field

[0001] The utility model relates to an audio decoder, in particular to an audio decoder with multiple interfaces. Background Art

[0002] An audio encoder is a device that converts digital audio information into analog audio signal output, and then decodes and restores the encoded multi-channel audio information. Existing audio decoders are generally divided into two types, one is a pure audio decoder for high-fidelity listening, and the other is an AV video decoder. Existing pure audio decoders need to directly output multiple signals, so many types of interfaces are installed on the pure audio decoder to support the output of different signals. Therefore, it is also called a multi-interface audio decoder device. When this multi-interface audio decoder device is used, its interface is generally fixed and welded on the internal motherboard to form a path with the internal motherboard, and then the various processing components and chips on the motherboard are used to process the signal. This fixed interface is inconvenient to replace after damage, and can only be sent to a specific after-sales store for repair after damage, which is more difficult to use. Utility Model Content

[0003] The utility model aims to solve the problem that the interfaces on the existing multi-interface audio decoder are mostly welded on the mainboard, and if they are damaged, they need to be repaired by a specific after-sales service, which causes inconvenience in use.

[0004] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0005] A multi-interface audio decoder comprises an audio decoder housing and a mainboard, wherein the mainboard is fixed inside the audio decoder housing by screws, a placement hole is provided on the back of the audio decoder housing, an interface docking board is fixed on one end of the mainboard close to the placement hole, a plug interface is provided on the interface docking board, a transfer interface seat is plugged into the plug interface, and the transfer interface seat moves inside the placement hole.

[0006] Preferably: an air inlet is provided at a position near one side of the top of the audio decoder shell, an air outlet bar is provided at a position away from the air inlet on the side of the audio decoder shell, a card seat is fixed to one side of the audio decoder shell, a heat sink is arranged at a position on the card seat corresponding to the air outlet bar, clamping strips are arranged at the top and bottom of the heat sink corresponding to the card seat, the heat sink is connected to the card seat through the clamping strips, a heat sink is arranged with a heat dissipation bar, a fan shell is arranged at one end of the heat sink, a cooling fan is arranged inside the fan shell, and the cooling fan is connected to the heat sink through the fan shell.

[0007] Preferably: a sealing strip is provided at the position where the heat sink contacts the audio decoder housing.

[0008] Preferably, a positioning groove is provided on the inner wall of the placement hole, and the adapter seat is plugged into the inside of the plug interface through the positioning groove.

[0009] Preferably: a dustproof net is provided on the air inlet.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] By setting the plug interface, the adapter seat and the placement hole, the plug interface is used to connect with the adapter seat, and the adapter seat is plugged into the plug interface through the placement hole. If an adapter seat is broken, it can be directly pulled out to the outside of the audio decoder shell to separate the adapter seat from the plug interface, and then a new adapter seat can be inserted into the placement hole and plugged into the plug interface, thereby achieving the effect of plugging and unplugging by means of the adapter seat card connection, solving the problem that the interfaces on the existing multi-interface audio decoders are mostly welded on the motherboard. If they are damaged, they need to be repaired by a specific after-sales service, which causes inconvenience in use.

[0012] By providing an air inlet, a heat dissipation bar, a heat sink and a heat sink fan, the heat sink fan drives the airflow at the heat sink position to move quickly, so that the airflow outside the audio decoder shell passes through the heat sink bar, so that it dissipates heat outside the heat sink bar, and the airflow inside the heat sink first enters the audio decoder shell through the air inlet, passes through the heating component, and then reaches the heat sink on the heat sink through the air outlet bar, and then the heat sink fan discharges the two groups of airflows at the same time, thereby accelerating the heat dissipation of the components inside the audio decoder shell and greatly improving the heat dissipation capacity.

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0019] See also Figures 1 to 4 In the embodiment of the utility model, a multi-interface audio decoder includes an audio decoder housing 1 and a mainboard 2. The mainboard 2 is fixed to the inside of the audio decoder housing 1 by screws. A placement hole 3 is provided on the back of the audio decoder housing 1. A positioning groove is provided on the inner wall of the placement hole 3 to position the transfer interface seat 6 to prevent it from rotating and affecting the plug-in effect. If the transfer interface seat 6 rotates, it will rub against the inside of the plug-in interface 5, affecting the electrical components inside the plug-in interface 5, thereby causing poor contact over time. The transfer interface seat 6 is plugged into the plug-in interface 5 through the positioning groove. Inside the interface 5, an interface docking plate 4 is fixed at one end of the mainboard 2 near the placement hole 3, and the interface docking plate 4 is provided with a plug-in port 5, and an adapter seat 6 is plugged into the plug-in port 5. The adapter seat 6 is movable inside the placement hole 3. When the adapter seat 6 is broken, move the adapter seat 6 to separate it from the placement port and the plug-in port 5, and then reinsert the new adapter seat 6 into the plug-in port 5 and the placement slot to achieve replacement. The purpose of convenient replacement is to replace different adapter seats 6 by oneself, and it is also convenient to replace the adapter without delaying use due to after-sales maintenance.

[0020] The top of the audio decoder housing 1 is provided with an air inlet 7 near one side, and a dustproof net is provided on the air inlet 7 to prevent dust from entering the interior of the audio decoder housing 1. The side of the audio decoder housing 1 is provided with an air outlet bar 8 away from the air inlet 7. Figure 2 The structure is shown as a grid, which increases the structural strength of the position and facilitates air outlet. A card seat 9 is fixed on one side of the audio decoder housing 1. A heat sink 10 is arranged at a position corresponding to the air outlet bar 8 on the card seat 9. A card strip 11 is arranged at the top and bottom of the heat sink 10 corresponding to the position of the card seat 9. The heat sink is connected to the card seat 9 through the card strip 11. A sealing strip 15 is arranged at the position where the heat sink 10 contacts the audio decoder housing 1 to increase the sealing of the connection position. The airflow inside the audio decoder housing 1 can flow. A heat sink bar 12 is arranged on the heat sink 10. One side of the heat sink 10 A fan shell 13 is provided at the end, and a cooling fan 14 is provided inside the fan shell 13. The cooling fan 14 is connected with the heat sink 10 through the fan shell 13. After the cooling fan 14 is started, it drives the airflow at this position to flow rapidly. The airflow enters the audio decoder housing 1 from the air inlet 7 and passes through the heating component, and then drives the generated heat to the heat sink 10. Subsequently, the airflow with heat is discharged from the cooling fan 14. At the same time, the airflow outside the heat sink 10 also flows rapidly to the surface of the heat sink 10 to dissipate the heat at the heat sink 10. In this way, increasing the rapid flow of air inside can greatly improve the heat dissipation.
