In a room with only a framed ceiling and no ceiling:
It is advisable to use a ceiling-mounted spherical speaker or a ceiling speaker with a rear cover. Since the ceiling is equivalent to an infinite baffle, using a speaker without a back cover under the condition of a ceiling will not cause an acoustic short circuit. The situation is very different without the ceiling. If you still use the ceiling speaker without the back cover, the effect will be very poor. In this case, ceiling-mounted speakers should be used in principle. However, if the investment is too large, ceiling speakers with a rear cover can also be used. The rear cover of the ceiling speaker with the rear cover not only has the general mechanical protection function, but also plays the role of preventing sound short circuit to a certain extent.
Indoors without ceilings:
It is advisable to use wall-mounted speakers or indoor sound columns.
outdoors:
An outdoor sound column or horn should be used. This kind of sound column and horn not only has the function of rainproof, but also has a large volume. Since the outdoor environment is empty and there is no reverberation effect, it is necessary to choose a variety with a higher volume.
In gardens and grasslands, lawn speakers should be used. This type of speaker is rainproof, beautiful in shape, and more particular about volume and sound quality. 25m~30m one, 20-25W.
In the halls with exquisite decoration and high ceilings, it is advisable to choose ceiling-mounted speakers with elegant shapes and harmonious colors.
In occasions with high requirements for fire protection, fire-resistant speakers should be selected. This type of loudspeaker is fully sealed, and its outlet can be mated with a flame retardant sleeve.
