Wherein, electronic equipment 11 specifically can be including integrated including TV, mobile phone, panel computer, PC or display etc.
There is the electronic equipment of a large amount of heating electronic components.
It should be noted that as when vibration unit 12 vibrates, the inside of casing 14 is opened along the first opening 141 and second
There is unidirectional air-flow to pass through at the adnexa and opening of 142 tie regions of mouth.Therefore, heat-generating units 11 may be located at casing 14
Inside, and one in the first opening 141 and second be open the tie region of in 142；Or it is located at casing 14
Opening outside.In electronic equipment as shown in Figure 1, it is that the second opening 142 for being located at casing 14 with heat-generating units 11 is
The explanation that example is carried out.
In embodiments of the present invention, vibration unit 12 can produce unidirectional radiating airflow by vibration.
Specifically, as shown in Figure 2 a, when vibration unit 12 is vibrated to first direction (direction shown in arrow in Fig. 2 a), case
Body 14 volume increase, in the case, casing 14 will by first opening 141 and second be open 142 inside air-breathings, wherein,
Second air inflow of first air inflow of the first opening 141 more than the second opening 142.
As shown in Figure 2 b, when vibration unit 12 is vibrated to second direction (direction shown in arrow in Fig. 4), the body of casing 14
Product reduces, and in the case, casing 14 will outwards be deflated by the first opening 141 and the second opening 142, the first opening 141
Second gas output of first gas output less than the second opening 142.
Wherein, the first air inflow is more than the first gas output, and the second air inflow is less than the second gas output.So, shaking
In the complete vibration period of of moving cell 12, the inflow end of the first opening 141 generally gas, and the second opening 142 is total
It is then the outflow end of gas on body, so as to being internally formed from 141 to second opening of the first opening, 142 flowing in casing 14
One-way gas flow.
It is possible to further see, in casing 14 as shown in Figure 2 a and 2 b, the first opening 141 and second is open
142 are water conservancy diversion cavity body structure.
First opening 141 first end sectional area more than the second end sectional area, second opening 142 the 3rd end cut
Sectional area of the area less than the 4th end.
Sectional area of the sectional area of the first end of the first opening 141 more than the 3rd end of the second opening 142, the first opening
Sectional area of the sectional area at 141 the second end less than the 4th end of the second opening 142.
Wherein, the 3rd end of the first end of the first opening 141 and the second opening 142 is near the one end at 14 center of casing；
4th end of the second end of the first opening 141 and the second opening 142 is the one end away from 14 center of casing.
Preferably, the first opening 141 is identical with the size of the water conservancy diversion cavity body structure adopted by the second opening 142, direction
It is identical, as shown in Fig. 2 a or 2b
Using the design of the water conservancy diversion cavity of such a structure, when vibration unit 12 is vibrated to first direction, first opens
Formed at mouthfuls 141 and significantly " expand and dredge stream ", and " jet " is then formed at the second opening 142, " expand and dredge stream " at the first opening 141
Flow more than second opening 142 at " jet ".When vibration unit 12 is vibrated to second direction, shape at the first opening 141
Into " jet ", and and then form " expand dredge stream " at the second opening 142, the flow of " jet " at the first opening 141 is less than second
" expand and dredge stream " being open at 142.So, within the complete vibration period of vibration unit 12, the first opening 141 is overall
On be gas inflow end, and second opening 142 be generally then gas outflow end, so as to being internally formed in casing 14
From the one-way gas flow of 141 to second opening of the first opening, 142 flowing.
Further, as shown in figure 3, electronic equipment also includes：
Radiating tube 15 outside casing 14, the radiating tube 15 are contacted with heat-generating units 11, for for the heating list
Unit 11 radiates.
Wherein, first opening 141 of one end connection of radiating tube 15, the second opening 142 of other end connection.
Wherein, radiating tube 15 can adopt the materials such as the aluminium with high heat-sinking capability to make, and be opened by the second of casing 14
The radiating airflows that mouth 142 flows out can flow to the first opening 141 in radiating tube 17.So, electronics need not be changed to set
Standby original circuit layout, radiating tube 15 can connect each heating heat-generating units, radiating airflow Bottomhole pressure so as to
Accelerate the radiating of various pieces.
Further, as shown in figure 4, electronic equipment can also include the control unit for driving vibration unit 12 to vibrate
16。
Control unit 16 can drive vibration unit 12 and be vibrated with predeterminated frequency.So, control unit 16 can be held
It is continuous to drive vibration unit 12 to be vibrated, substantially increase the persistence and stability of electronic equipment dissipating heat.Wherein, control unit
16 may be located at the internal or external of casing 14, in electronic equipment as shown in Figure 3, be to be located at casing 14 with control unit 16
Inside as a example by the explanation that carries out.
Specifically, control unit 16 can include：First control subelement 161 and the second control subelement 162.
First control subelement 161 carries out mechanical vibration with predeterminated frequency, and is connected with vibration unit 12, for driving
Vibration unit 12 is vibrated with predeterminated frequency.
Specifically, the first control subelement 161 can adopt it is existing any one can carry out the machinery of mechanical vibration
Device.For example, the first control subelement 161 can be moved back and forth using Motor drive connecting shaft, the other end of connecting shaft
Connection vibration unit 12, so that vibration unit 12 is vibrated with identical frequency.Can by the first control subelement 161
To realize carrying out electronic equipment the radiating of low noise.
Second control subelement 162 drives vibration unit 12 to be vibrated with predeterminated frequency by the sound wave for sending.
Wherein, the second control subelement 162 can specifically include：
There is module 1621 in first frequency, the sound wave for sending first frequency drives vibration unit 12 with the first frequency
Vibrated.
There is module 1622 in second frequency, the sound wave for sending second frequency drives vibration unit 12 with the second frequency
Vibrated.
Wherein, the sound wave that the sound wave of first frequency can be experienced for human ear, the sound wave of second frequency can not be felt for human ear
The sound wave being subject to.For example, the sound wave of first frequency is specifically may be greater than equal to 20Hz and less than or equal to the distinguishable sound of 20kHz
Ripple, the sound wave of second frequency can then be less than the infrasonic wave equal to 20Hz or the ultrasound wave more than or equal to 20kHz.So may be used
To realize that the frequency for driving vibration unit to can't hear with human ear or being difficult to hear produces vibration.So, by first frequency
There is module 1621 to realize the broadcasting of electronic equipment sound simultaneously and radiate electronic equipment, so as to avoid
Noise produced by during driving vibration unit；There is module 1622 by second frequency then to realize entering electronic equipment
The radiating of row noiseless or low noise.
For example, as shown in figure 3, the second control subelement 162 can be speaker, the speaker again can be including the first frequency
There is module in rate and second frequency occurs module.The speaker can send the sound of the sound wave or second frequency of first frequency respectively
Ripple, when electronic equipment needs to carry out the audio output of the machine, speaker can occur module 1621 by first frequency and send
Sound is listened to so as to user.
The speaker can be arranged at the internal or external of casing 14 according to actual needs.When speaker is located at casing 14
The prototype structure of electronic equipment when outside, can be changed, and only casing 14 need to be added electronic equipment；Work as speaker
Positioned at the inside of casing 14 when, the sound that speaker sends can be shaken in box house, so, by reasonably changing casing
14 shape or structure may act as the audio amplifier of the speaker, so as to improve speaker while radiating effect is ensured
Result of broadcast.
Wherein, the sound wave that speaker can pass through to send drives vibration unit 12 to vibrate, in the electronic equipment shown in Fig. 3
In, it is the explanation carried out so that speaker is arranged at the inside of casing 14 as an example.For example, so that electronic equipment is as television set as an example, when
When user watches program using television set, speaker typically lasts for sending sound, so as to cause air strong near speaker
Vibration, can then drive vibration unit to produce the vibrations of same frequency using the vibration, so as to produce unidirectional radiating airflow.So
One, the effect of active heat removal can be obtained without the need for additionally arranging the device for driving vibration unit by the vibration of vibration unit
Really, so as to avoid the noise that sent when driving means work, additionally, the apparatus structure of such a radiating is simple, can be with
It is placed directly near the speaker of electronic equipment, and without the need for additional designs circuit, reduces the production difficulty of electronic equipment.
Or, as shown in figure 5, the sound-emitting membrane of speaker can be vibration unit 12.In electronic equipment as shown in Figure 5
In, the explanation for equally carrying out so that speaker is arranged at the inside of casing 14 as an example.So, when speaker sends sound,
The sound-emitting membrane of speaker will be directly as vibration unit 12, so as to without the need for driving indirectly vibration unit 12 by air vibration
Raw vibrations.Due to sound wave as the increase of propagation distance in atmosphere, wave energy will be gradually reduced, the sounding using speaker is thin
Film can be effectively ensured the amplitude of vibration unit directly as the mode of vibration unit 12, improve air flow amount, improve radiating
Effect.On the other hand, circuit block, such a can be increased as vibration unit 12 using the sound-emitting membrane of speaker
The electronic equipment of structure can avoid the increase of product thickness and circuit structure while radiating effect is improved, and further reduce
The production cost of product.
Further, as shown in figure 4, electronic equipment can also include：
Trigger element 17, the first frequency sound wave satisfaction first for sending when determination first frequency generation module 1621 are pre-
During fixed condition, triggering first controls subelement 161 or second frequency occurs module 1622 and drives vibration unit 12 to vibrate.
It should be noted that triggering first controls subelement 161 or second frequency occurs module 1622 and drives vibration unit
Pre-conditioned can be user artificially determine first met required for 12 vibrations according to practical situation.For example, can specify that
When the volume that first frequency occurs the first frequency sound wave that module 1621 sends is sent out less than or equal to default volume value, or first frequency
When raw module 1621 stops sending the time of first frequency sound wave and is more than or equal to predetermined threshold value, it is believed that user now reduce or
The sound of electronic equipment is closed, in order to persistently radiate to electronic equipment, triggering first controls subelement 161 or the second frequency
There is module 1622 and drive vibration unit 12 to vibrate to realize carrying out electronic equipment noiseless or low noise radiating in rate.
Further, when it is determined that first frequency occurs first frequency sound wave the first predetermined condition of satisfaction that module 1621 sends
When, trigger element 17 stops while the first control subelement 161 is triggered or one of module 1622 second frequency occurs
Other control units drive vibration module 12 to vibrate.For example, when it is determined that first frequency occurs the first frequency that module 1621 sends
When rate sound wave meets the first predetermined condition, trigger element 17 enables first and controls subelement 161, while first frequency will be closed
There is module 1622 in generation module 1621 and second frequency.So, the noise produced in reduce further radiation processes.
So that user is using TV as an example, when TV normal work, the sound that speaker sends will drive vibration unit to shake
It is dynamic, so as to produce the one-way gas flow for being radiated to television internal heat-generating units.When user is by the audible closure of speaker
Or when volume is reduced to very little, now it is considered that user needs TV display image, in order to ensure lasting radiating, triggering
Unit will trigger speaker and send human ear not to be heard or is difficult the ultrasound wave heard or infrasonic wave, or trigger element can be triggered
Machinery drives vibration unit vibration.So, the noise of electronic equipment active heat removal is reduced, radiating effect is improve
Really.
Further, as shown in figure 4, electronic equipment can also include：Display unit 18 and interface unit 19.
When view data being obtained from interface unit 19, when the view data is exported by display unit 18, start control unit
16 are vibrated with predeterminated frequency with driving vibration unit 12.
It is same either directly to be surfed the Net using TV by taking TV as an example, or simultaneously conduct should to use TV connection computer
The extension screen of computer, or TV only plays local image, when obtaining view data from interface unit 19, the picture number
During according to being exported by display unit 18, due to all no audio frequency, control unit 16 can be started and drive vibration unit 12 to be vibrated
To radiate to TV.For example, the speaker of TV so, can be being realized to TV with shuffle music
While radiating, the impression of user is further improved.
