Description
Technical field
The present invention relates to technical field of electronic equipment, particularly relate to a kind of projection-type electronic equipment and electronics sets
Standby.
Background technology
Along with the development of science and technology, electronic technology have also been obtained development at full speed, the kind of electronic product
Class also gets more and more, and people have also enjoyed the various facilities that development in science and technology brings.People can pass through now
Various types of electronic equipments, enjoy the comfortable life brought along with development in science and technology.Such as, the electricity such as projector
Subset has become as an important ingredient in people's life, and people can pass through projector in meeting
Middle projection data explains scheme to conference participation person, it is also possible to by projector viewing film etc., very
Convenient.
At present, when electronic device works such as projectors, power pack in the electronic equipment such as projector and
Projection bulb's part all can produce substantial amounts of heat, then can affect the work effect of the electronic equipments such as projector
Rate, such as, the quartz of the bulb inner wall of projector at high temperature can occur devitrification phenomenon, and (devitrification is quartz glass
One inherent shortcoming of glass, when temperature is too high, silicon dioxide molecules vibration was accelerated, through one period of long period
Rearrange, orient just form crystallization), the speckle of a large amount of white can be produced at devitrification, owing to being to lose
Place stops light thoroughly so that this temperatures at localized regions is abnormal to be raised, and then causes the further expansion in devitrification region
Greatly, so that the brightness of projector decays rapidly, and it is likely to cause bulb to explode；The most such as,
The physical property of the circuit board within projector self determines its operating temperature and does not allow the highest, if work
Make temperature the highest, the structure of circuit board can be affected, thus affect the normal work of projector.
In the prior art, in order to ensure the normal use of projector, high temperature is reduced to the unit within projector
The impact of device, generally uses fan or fan group to accelerate the air flowing within projector, to reduce throwing
Temperature within shadow instrument.
But during the technical scheme that the present inventor is in realizing the embodiment of the present invention, find above-mentioned technology extremely
There is following technical problem less:
The electronic equipments such as projector operationally, the power pack in the electronic equipment such as projector and projecting lamp
Bubble part can produce substantial amounts of heat, for ensureing that these heats can be effectively conducted to outside projector,
Typically can use powerful fan, these powerful fans are when high-speed rotation, and rotating speed typically exists
5000rpm(rev/min), the most even can reach 10000rpm, thus substantial amounts of noise can be produced, fall
The low Consumer's Experience of electronic equipment, such as, user in a meeting by projector data to participating in meeting
When view person explains scheme, the fan within projector is owing to sending when high-speed rotation can send similar Apis flight
" drone " noise, conference participation person is particularly closer from projector, and the sound heard can be especially
Greatly, Consumer's Experience is reduced；The most such as, by projector one film of viewing when, in projector
The fan in portion owing to high-speed rotation can send aforementioned described " drone " noise, thus affect people and seeing
See audio experience during film, reduce Consumer's Experience.
Therefore, prior art exists by the way of fan reduces electronic equipment internal temperature generation extra
The technical problem of noise, simultaneously as electronic equipment operationally can produce extra because of fan high-speed rotation
Noise, so the audio experience of the user using this electronic equipment can be affected, reduces electronic equipment then
Consumer's Experience.
