Abstract
The disclosure provides a projection apparatus, which includes a casing, a projection module, at least one airflow generating unit, and at least one speaker. The casing has at least one air outlet. The projection module is disposed in the casing and configured to project an image beam outside the casing. The airflow generating unit is disposed in the casing and configured to generate airflow. The speaker is disposed in the casing, and the airflow generating unit is located between the projection module and the speaker. The speaker has at least one flow guiding surface, and the flow guiding surface is inclined toward the air outlet to guide the airflow toward the air outlet. The projection apparatus has a favorable heat dissipation capability and may reduce the noise generated by the airflow generating unit.
