Description
Technical field
The utility model relates to a kind of buzzer structure, the piezo buzzer knot of specially a kind of high sound press of low frequency
Structure.
Background technique
Conventional diameter is all 4KHZ higher in the frequency of the small-sized piezoelectric formula buzzer of 12*7mm, and sound is more sharp, and
When source driving signal is adjusted to 2KHZ clearer and more melodious sound frequency, the usual 60 ~ 70DB of buzzer sound press value and sound press value are needed
It asks compared to smaller, cannot meet the requirements well.In addition to this, home wiring control plate currently on the market is always to use 12085-
The electromagnetic buzzer of 2KHZ is in the majority, but since electromagnetic buzzer constructs complexity, the coefficient of stability of product is unlike piezoelectric type
, and be that consumption electric current is relatively high, the power consumption of complete machine is influenced, so piezo buzzer should be taken as far as possible.
So being badly in need of developing the high sound press small size piezoelectric type product of a piezoelectric type 2KHZ frequency, to replace current portion
Electromagnetic buzzer in sub-control making sheet.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of piezo buzzer of the high sound press of low frequency, the buzzer energy
Enough that the piezo buzzer of low frequency and high sound press is provided in the case where small volume, the means which takes are to pass through
Sound hole is limited, sound hole is faced the wall and meditated thickness, and the size of resonant cavity depth and first diameter achieves the desired results.
In order to solve problem above, purpose of the utility model is realized as follows: a kind of piezoelectricity of the high sound press of low frequency
Formula buzzer characterized by comprising stitch, cover board, piezo, shell, sound hole, shell resonant chamber, the first gap, cover board
Base angle, shell face the wall and meditate, first diameter, the stitch there are two and symmetrical be inserted in cover board；The cover board bottom has
Two cover board base angles are distributed in two sides；It is the first gap between the cover board base angle and piezo；The piezo setting is outside
Convex on the inside of shell, top are contacted with two stitch；The sound hole is in shell just in the following, rounded distribution;The interior of shell
There are a shell resonant chamber and shell to face the wall and meditate, inside the housing, it is the main component composition of shell that shell is faced the wall and meditated to shell resonant chamber,
There is the first diameter for describing width below interior of shell；The shell resonant chamber is the main cavity composition of shell；
Further, the clearance distance between the first gap is 0.15mm.
Further, sound hole diameter is 2.9mm.
