[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1 Reference Figure 1-6 As shown, this utility model discloses a combined audio system, including an audio storage unit and an audio playback unit 1, which can be used after being combined. The storage unit includes a cover, within which a fourth circuit board 21 is installed. A chip for storing sound effect files is installed on the fourth circuit board 21, and a contact 211 penetrating the cover is connected to the fourth circuit board 21. Figure 1 and Figure 2 It can be seen that the audio playback component 1 is used to accommodate and connect the audio storage component, so as to complete the combined use of the two, such as... Figure 3-6 It is understood that the audio playback device 1 includes a base 11, a main body 12, a front shell 13, a rear shell 15, and an upper shell 14. The main body 12 is connected to the front shell 13, the rear shell 15, and the upper shell 14 and fixed on the base 11. The main body 12 includes an upper middle cover 129, an upper inner liner 121, and a lower inner liner 122 connected in sequence. A second circuit board 128 is installed between the upper middle cover 129 and the upper inner liner 121. A contact pin 1281 that penetrates the upper middle cover 129 is connected to the second circuit board 128. The contact pin 1281 is plugged into and cooperates with the contact 211 to electrically connect to the fourth circuit board 21. A speaker 123 and a battery 125 are installed between the upper inner liner 121 and the lower inner liner 122. The battery 125 is electrically connected to the third circuit board 134 and the speaker 123.

[0025] The combined audio system of this application features a built-in security key for the audio effect files stored in the audio storage unit. When the audio storage unit and the audio playback unit 1 are combined, the contact pin 1281 and contact 211 are electrically connected, enabling decoding (preventing non-dedicated audio storage units from connecting to the audio playback unit 1) and communication transmission to the dedicated audio playback unit 1 for playback. This dedicated audio playback unit 1 does not require any WiFi network connection; it only needs to be powered on to enter standby mode. The decoding operation refers to the fact that a specific key is pre-stored in the chip of the fourth circuit board 21. After the second circuit board 128 is electrically connected, it sends a verification command. Only after successful verification can the audio effect file data be read. The decoding or verification matching is a function that can be obtained through appropriate software adaptation modifications in the prior art. Example 2 Reference Figure 1-6As shown, based on the technical solution of Embodiment 1, a combined audio system, regarding the specific structural design of the audio storage component, is as follows: Figure 3-6 As can be seen, the cover includes an upper cover 20 and a lower cover 23, which can be assembled by a positioning shaft to form a closed cover.

The countersunk hole matches the size of the cylinder. In addition, to ensure accurate alignment of the contact pin 1281 and the contact 211, the area where the second mounting hole 231 is located is designed as a convex structure, and the area where the first mounting hole 1291 is located is designed as a concave structure. The convex and concave structures can be fitted together to achieve the operation of the contact pin 1281 and the contact 211 being inserted and mated for electrical connection. To prevent misalignment during the assembly of the lower cover 23 and the upper middle cover 129, the convex structure is located on the D-shaped concave surface, and the concave structure is located on the D-shaped convex surface. The D-shaped concave surface and the D-shaped convex surface can be fitted together to achieve accurate operation of the front and back orientations during the assembly of the lower cover 23 and the upper middle cover 129.
