Abstract
An ear cup structure including an ear cup shell, a cover, a discharge hole, a speaker, and a guide channel is provided. The ear cup shell has at least a first accommodating space and a second accommodating space spaced from each other, and the second accommodating space has a second opening. The cover covers the second opening of the second accommodating space. The discharge hole is formed between the ear cup shell and the cover. The speaker is disposed in the second accommodating space, thereby dividing the second accommodating space into a front chamber and a rear chamber. The guide channel is communicated with a peripheral side of the rear chamber and is disposed between the rear chamber and the discharge hole. An airflow produced by the speaker in the rear chamber flows through the guide channel and is discharged to an external environment from the discharge hole.
