Standby, in this way, when attendance is very low, the stereo set being all turned on causes the very big waste of resource.
Based on this, an embodiment of the present invention provides movie theatre sound controller and systems, are carried out below by embodiment
Description.
Embodiment 1
Referring to Fig. 1, Fig. 2, Fig. 3 and Fig. 4, the movie theatre that the present embodiment proposes is specifically included with sound controller：Centre
Manage device, stereo set and the weight sensor being arranged on each seat, in order to accurately and effectively perceive on each seat whether
It takes down, each weight sensor is arranged on the seat of seat, the weight sensor when someone sits down on the seat
Acquire the gravimetric value of viewing person on seat.Also, each weight sensor is wirelessly connected with central processing unit, for example, passing through
Bluetooth etc., stereo set is wirelessly connected with central processing unit, for example, by bluetooth, WIFI etc., compared with wired connection, wirelessly
Connection eliminates the complicated processes of wiring.
In addition, in order to keep the audio in entire viewing space uniform, stereo set is circumferentially positioned at the different height of movie theater
On position, in implementation process, weight sensor is used to detect taken on seat under when gravimetric value, also, according to described
Gravimetric value generates seat of honour signal, and later, seat of honour signal is sent to central processing unit by weight sensor, when central processing unit receives
After the seat of honour signal sent to each weight sensor, central processing unit counts the total number of seat of honour signal, in order to preferable
It is measured, the statistics of the total number of seat of honour signal is carried out usually as unit of a viewing movie theater, certainly, if stereo set
It uses, is just counted accordingly with the total number of the seat of honour signal of entire movie theater, also, central processing for entire movie theater
Device will also calculate the percentage that seat of honour signal accounts for seat sum, i.e., practical viewing number accounts for the percentage of total number of persons.
Later, central processing unit is additionally operable to compare the relationship of percentage and preset threshold range, is said
Bright, above-mentioned preset threshold range is corresponding numerical value when attendance situation is preferable, preferably 40% to 90% it
Between.In specific implementation process, when percentage is more than the upper limit of above-mentioned threshold range, central processing unit controls the first height position
The stereo set set is opened；When percentage is in threshold range, central processing unit controls the sound equipment on the second height and position
Opening of device；When percentage is less than the lower limit of threshold range, the sound equipment that central processing unit also controls on third height position is set
It is standby to open.By the setting of preset threshold range, can be opened according to the different numerical value of above-mentioned percentage different
Stereo set, to realize according to viewing person number adjust the purpose of stereo set, it is convenient and efficient.
Stereo set on above-mentioned first height and position includes：Bottom supporting table 4, casing assembly 7, the first head unit 8,
First power amplifier 5 and fan 6, need to illustrate, and the first height and position is the height that distance perpendicular to the ground is less than 0.1 meter
Degree, since ground is possible to moister in cleaning process, therefore, stereo set is arranged and is less than in ground vertical range
It in 0.1 meter of height, rather than is directly placed on ground, the influence to stereo set such as moisture can be reduced, to extend
The service life of stereo set.
In addition, when percentage is more than the upper limit (i.e. viewing number is more) of above-mentioned threshold range, central processing unit control
Stereo set on first height and position is opened, due to, distance of the stereo set apart from ground is closer, and the sound is larger,
Use demand is disclosure satisfy that in the case that viewing person is more.In order to place the stereo set well, above-mentioned bottom supporting table
Upper surface setting is fluted, and setting groove can effectively prevent the stereo set to be slid from the supporting table of bottom, also, bottom branch

In order to facilitate the installation of, above-mentioned supporting rack is broken line type, also, the angle adjustable of supporting rack, consequently facilitating operation
Personnel are adjusted, and in order to ensure the safety of stereo set, the material of supporting rack is usually steel etc..In specific implementation process
In, one end of supporting rack is mounted on wall, the bottom end of the other end connection ventilation shell of supporting rack, also, in order to effectively drive
The heat that scattered stereo set distributes during the work time, ventilation shell are a closed shell, are set on the side wall for shell of divulging information
Multiple through-holes are equipped with, the inside for shell of divulging information is for wrapping up the second head unit and the second power amplifier, in use, the second head unit
For sending out second sound after receiving the second open signal that central processing unit is sent out, later, in order to keep acoustics more aobvious
It writes, the second power amplifier after being amplified the power of second sound for exporting.
Stereo set on above-mentioned third height position includes：Vertical loading board 13, peripheral shell 16,14 and of third head unit
Third power amplifier 15 needs to illustrate, and third height position is the height that distance perpendicular to the ground is 2.5 meters, by third
The height that it is 2.5 meters in distance perpendicular to the ground that height and position, which is arranged, is to lift for convenience.Above-mentioned vertical loading board is a connection
One end of bar, vertical loading board is connected on the inside of roof, the top of the peripheral shell of other end connection of vertical loading board, by way of lifting
Peripheral shell is fixed.Also, above-mentioned periphery shell is internally provided with third head unit and third power amplifier, uses
Cheng Zhong, third head unit are used for sending out the third sound after receiving the third open signal that central processing unit is sent out, later, in order to
Keep acoustics more notable, third power amplifier after being amplified the power of the third sound for exporting.
In addition, there is drainage, the outer surface of above-mentioned bottom supporting table and casing assembly in the roof of movie theatre in order to prevent
It is enclosed with waterproof membrane.Common waterproof membrane is plastic material, in this way, being capable of effective protection to the resistance of moisture content by waterproof membrane
It is arranged in the supporting table of bottom, the stereo set in casing assembly.
In addition, in order to save electric energy as possible, above-mentioned first head unit, the second head unit and third head unit work
It is different to make voltage, in order to meet the needs of viewing person's number, above-mentioned first head unit, the second head unit and third sound
The numerical value for ringing the operating voltage of ontology descending should be set gradually, and the numerical value of specific works voltage can according to circumstances carry out spirit
Setting living.
In addition, in order to be adapted with the number of viewing person, above-mentioned first power amplifier, the second power amplifier and third power amplifier times magnification
Number is different.Need to illustrate, the amplification factor of above-mentioned first power amplifier, the second power amplifier and third power amplifier should with it is upper
It states the first head unit, the second head unit and third head unit to match, the amplification range of its own, tool can not be exceeded
The numerical value of the amplification factor of body according to circumstances can flexibly be set.
In addition, in order to keep the acoustics in viewing movie theater uniform as possible, above-mentioned first head unit, the second head unit
It is equal with the horizontal distance of third head unit between any two, i.e., above-mentioned first head unit, the second head unit and third sound
It rings ontology and is uniformly arranged on viewing space interior, also, during follow-up maintenance, overhauled etc. convenient for setting up equipment.
In addition, in order to ensure that weight sensor can accurately measure the gravimetric value of viewing person, movie theatre is controlled with sound equipment and is filled
