This embodiment provides an acoustic enclosure, as shown in fig. 1, 2 and 3, the acoustic enclosure comprising: a housing 100, a cover 200 and a horn assembly 300. The speaker assembly 300 is used for receiving and playing external audio data, and includes a sound generation module and a receiving module. The receiving module is used for receiving external audio data, the receiving module is connected with the sound production module, the receiving module processes the processed audio data, and the audio data is converted into a wave signal from an electric signal through the sound production module, so that music playing is achieved. The housing 100 is in communication with the cover 200 to form a first cavity in the housing 100 for accommodating the sound module and a second cavity in the cover 200 for accommodating the receiving module. In order to facilitate the connection between the external device and the receiving module, a plurality of connection ports 10 for connecting the receiving module and the input device are provided on the cover 200.

In fig. 1, the connection ports 10 provided on the cover 200 include a network connection port, an HDMI connection port 10, a 3.5mm connection port, a USB connection port of a different transmission protocol, and the like, and the connection ports 10 in the drawing are only illustrative of the connection ports 10 that can be provided, and different types of connection ports 10 can be provided on the cover 200 depending on the installation of the reception module. Therefore, when the external device is connected to the speaker, the user only needs to adjust the direction of the cover 200. Meanwhile, a plurality of sound emitting holes are uniformly distributed on the casing 100, when the user adjusts the direction of the cover body 200, the direction of the casing 100 is changed accordingly, and due to the uniform distribution of the sound emitting holes, the sound is emitted uniformly, so that the user can enjoy the audio frequency no matter how the direction of the casing 100 is changed.

The sound emitting holes 110 may be circular, oval, irregular, etc. In the scheme, in order to facilitate the transmission of sound, increase the sound production effect, and increase the friction force when a user holds the shell, the sound emission holes 110 are distributed all over the shell 100, and the sound emission holes 110 are inclined holes distributed in sequence. The casing 100 itself may be made of metal material such as iron and alloy, etc. to increase the stability of sound generation. As shown in fig. 4, the inclined holes are arranged in a form inclined at an angle of 30 degrees, and the sound emitting holes 110 in the upper and lower rows are staggered.
