Description
Technical field
The present invention relates to the ceiling loudspeaker of sound equipment, specifically a kind of Ceiling loudspeaker housing.
Background technique
Ceiling loudspeaker is typically mounted on indoor suspended ceiling ceiling (also known as ceiling etc.) or is snugly mounted on wall (compartment
On wall etc.).In recent years, with technological progress, people are to ceiling loudspeaker (also known as ceiling loudspeaker, hidden speaker etc.)
Broadcasting sound quality requirement is higher and higher, and mounting height requires smaller and smaller.In Fujian, science tech publishing house publishes in July, 2008
" loudspeaker and speaker design manual " in, disclose closed speaker (page 60~67), open type speaker (page 67~77), nothing
Source radiation speaker (page 77~78)；These disclosed prior art speakers or be that volume is too big, mounting height is too big or
Bass reproduction is ineffective.It is the loudspeaker for having mounting rack frame, bore one with the ceiling loudspeaker of the prior art
As be 5.25 inches to 8 inches, be mounted on ceiling, it is close due to cannot achieve using the space of ceiling as " cabinet "
Envelope, and it is exactly very much too small that ceiling space is not greatly, thus cannot achieve the sound box of real meaning, it is at most exactly a sound
Big baffle is learned, in addition the speaker height of these prior arts is all very big, and all in 80mm or more, and the installation space of ceiling is very
It is limited, it installs and uses and creates great difficulties to ceiling loudspeaker.
