Problems solved by technology

[0002] At present, the projector includes many components such as light engine, audio, etc. Due to the complex structure of the projector and the large number of components, all components are installed in a limited space, resulting in insufficient space to install speakers , as we all know, the larger the volume of the speaker, the larger the diameter of the horn, the better the bass effect, because there is not enough space to install the speaker, the sound cavity of the speaker is small, resulting in the inability to produce good sound quality

Embodiment Construction

[0042] It should be understood that the specific embodiments described here are only used to explain the present invention, and are not intended to limit the embodiments of the present invention.

[0043] Such as Figure 1-Figure 4 As shown, a projector according to an embodiment of the present invention includes a casing 1, an optical machine 2, and an audio system 3 having a low-frequency speaker 30 and a cylindrical mounting case 31. The optical machine 2 and the audio system 3 are stacked and can be It is detachably arranged in the housing 1 , and the low-frequency speaker 30 is arranged at any mouth of the installation casing 31 .

[0044] Wherein, the housing 1 is provided with an optical machine opening 10 adapted to the projection lens of the optical machine 2 , so that the projector can project an image onto a predetermined shadow cloth or wall through the optical machine opening 10 .

[0045] Wherein, the main board 7 of the optical machine 2 can be fixed on the cas...

Abstract

The invention relates to a projector which comprises a shell, an optical machine and a sound box with a low-frequency loudspeaker and a cylindrical mounting shell. The optical machine and the sound box are stacked and detachably arranged in the shell, and the low-frequency loudspeaker is arranged at any cylindrical opening of the mounting shell. The optical machine and the sound box are stacked in the shell, the low-frequency loudspeaker is mounted at any cylinder opening of the mounting shell, and when the low-frequency loudspeaker is independently mounted and the cylindrical mounting shell is used as the sound cavity of the low-frequency loudspeaker, since the circular area is maximum under the condition of the same perimeter, thus the space surrounded by the cylindrical mounting shell is relatively large, the sound cavity of the sound box can be effectively enlarged, the bass effect can be greatly improved, the tone quality is ensured, and the user experience is improved; moreover, the optical machine and the sound box are detachably connected to the shell, so that the use is more flexible, and the user experience is further improved.

Description

technical field [0001] The invention relates to the technical field of projectors, in particular to a projector with a low-frequency speaker. Background technique [0002] At present, the projector includes many components such as light engine, audio, etc. Due to the complex structure of the projector and the large number of components, all components are installed in a limited space, resulting in insufficient space to install speakers , as we all know, the larger the volume of the speaker, the larger the diameter of the speaker, the better the bass effect, because there is not enough space to install the speaker, the sound cavity of the speaker is small, resulting in the inability to produce good sound quality. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a projector with a low-frequency speaker in view of the deficiencies in the prior art. [0004] The technical scheme of a kind of projector of the present ...
