Description

Technical Field

[0001] The invention relates to the technical field of audio, and in particular to a mobile audio with waterproof function. Background Art

[0002] In recent years, mobile speakers are used in many large-scale outdoor entertainment activities. Existing mobile speakers have mesh covers on the speakers to prevent dust and protect the speakers. However, outdoor speakers are often exposed to rain when in use, so existing mobile speakers usually have a waterproof function.

[0003] However, the sealing structure for waterproofing makes the speaker in a closed state, which affects the heat dissipation of the speaker, causing heat to accumulate inside the speaker when used for a long time, accelerating the aging of the components inside the speaker. When it rains, if the speaker needs to be used in thunderstorms, rainwater will pass through the mesh cover and flow between the mesh cover and the speaker. The rainwater continues to adhere to the surface of the speaker, which will affect the amplitude of the speaker diaphragm, thereby affecting the sound effect and sound quality of the speaker. In addition, the rainwater continues to remain between the mesh cover and the speaker, which will cause the rainwater to gradually penetrate into the interior of the speaker, causing the electronic components in the speaker body to age or even be damaged. Summary of the invention

[0004] In order to overcome the disadvantage that the sealing structure of the existing speakers affects the internal heat dissipation of the speakers, when it rains, rainwater continues to remain between the mesh cover and the speaker, affecting the sound effect of the speaker and causing the rainwater to gradually penetrate into the speaker, causing the electronic components in the speaker body to age or even be damaged, the present invention provides a mobile speaker with a waterproof function.

DETAILED DESCRIPTION

[0018] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments.

[0019] Example 1 A portable speaker with waterproof function, such as Figure 1-Figure 4 As shown, it includes a sound body 1 and a dustproof net cover 2; the sound body 1 is provided with electronic components, and a speaker 1001 is installed on the front side of the sound body 1; a pull rod is provided on the rear side of the sound body 1, and a running wheel is provided on the bottom of the sound body 1; the dustproof net cover 2 is connected to the front side of the sound body 1; It also includes a guide plate 3, a ventilator 4, a cooling fan 5, a shielding plate 7 and a water baffle 8; the guide plate 3 is fixedly connected to the upper side of the interior of the audio body 1; a first opening 3001 is opened on the front side of the guide plate 3, and an air inlet 1002 is opened on the lower side of the audio body 1; a ventilator 4 is fixedly connected and connected between the guide plate 3 and the audio body 1, and the ventilator 4 is connected to the air inlet 1002; a cooling fan 5 is installed at the connecting port between the guide plate 3 and the ventilator 4; an air outlet 1003 is opened on the upper side of the audio body 1; a shielding plate 7 is rotatably connected to the upper side of the air outlet 1003; a water baffle 8 is installed on the front side of the audio body 1, and the water baffle 8 is in close contact with the speaker 1001.

[0020] A dryer 6 is also included; the dryer 6 is installed between the guide plate 3 and the audio body 1; the dryer 6 is located at the rear side of the first opening 3001.

[0021] A water leakage hole 1004 is provided at the lower front side of the speaker body 1 ; the water leakage hole 1004 is located between the speaker 1001 and the dustproof mesh cover 2 .

[0022] The side wall of the ventilator 4 is provided with heat dissipation fins to accelerate the speed of heat transfer from the interior of the audio body 1 to the ventilator 4 .

[0023] The first opening 3001 is located at the front side of the speaker 1001 ; and the first opening 3001 is flush with the speaker 1001 and the water baffle 8 to enhance the blowing of rainwater on the surface of the speaker 1001 .

[0024] The dustproof mesh cover 2 is plugged into the sound body 1 to facilitate the removal and cleaning of the dustproof mesh cover 2.

[0025] A sealing strip is provided on the lower side of the shielding piece 7 to enhance the blocking effect of the shielding piece 7 on the air outlet 1003 .

[0026] A sealing strip is provided on the upper side of the frame of the dustproof mesh cover 2 to enhance the plugging stability between the dustproof mesh cover 2 and the audio body 1 .

[0027] like Figure 1 As shown, the side where the dust screen 2 is located is the front side. When the present invention is needed, the pull rod on the sound body 1 can be pulled to move the present invention to the desired location for use. During use, Figure 4 As shown, the initial shielding piece 7 does not block the air outlet 1003, and the heat generated by the electronic components in the audio body 1 is conducted to the heat dissipation fins of the ventilator 4. By controlling the heat dissipation fan 5 to rotate, the air in the ventilator 4 is drawn to between the guide plate 3 and the audio body 1, and then the gas is blown out from the air outlet 1003, so that the air enters the ventilator 4 from the outside through the air inlet 1002, and the gas carrying the heat of the heat dissipation fins is blown out of the audio body 1, thereby achieving heat dissipation inside the audio body 1, so as to avoid long-term accumulation of heat in the audio body 1, which may cause aging or even damage of the electronic components in the audio body 1.

[0028] When it rains, and the present invention needs to be continued to be used during thunderstorms, the shielding piece 7 is manually twisted to block the air outlet 1003 through the shielding piece 7 to prevent rainwater from entering the audio body 1 through the air outlet 1003. Since the air outlet 1003 is blocked at this time, the gas drawn by the cooling fan 5 to between the guide plate 3 and the audio body 1 will pass through the dryer 6. After the gas passes through the dryer 6, the gas flows outward from the first opening 3001 to achieve heat dissipation inside the audio body 1. At this time, rainwater will continuously pass through the dustproof mesh cover 2 and adhere to the speaker 1001. At this time, the rainwater is blocked by the water baffle 8 to prevent rainwater from entering the audio body 1, and under the action of gravity, part of the rainwater can flow downward from the leakage hole 1004.

[0029] However, some rainwater is always attached to the surface of the speaker 1001. Since the speaker 1001 is making sound at this time, the rainwater attached to the surface of the speaker 1001 will affect the sound effect of the speaker 1001 and the sound quality. Therefore, the gas blown downward from the first port 3001 is used to blow the rainwater on the surface of the speaker 1001 to promote the rainwater on the surface of the speaker 1001 to move downward quickly, so as to avoid the rainwater from continuously adhering to the surface of the speaker 1001 and affecting the sound effect of the speaker 1001. At the same time, the rainwater that is continuously attached to the surface of the speaker 1001 is prevented from penetrating into the audio body 1, causing the electronic components in the audio body 1 to become damp and damaged.

[0030] Furthermore, since the air is relatively humid when it rains, the gas drawn into the ventilator 4 by the cooling fan 5 and blown out from the first port 3001 is in a humid state. Since the humid gas only circulates in the ventilator 4 and in the area between the guide plate 3 and the audio body 1, the humid gas is prevented from coming into contact with the electronic components inside the audio body 1 while dissipating the heat inside the audio body 1, thereby ensuring that the humid gas will not damage the electronic components inside the audio body 1 when dissipating the heat from the audio body 1 on rainy days. Furthermore, by starting the dryer 6, the gas passing through the dryer 6 is dried to ensure that the gas blown out from the first port 3001 is in a dry state, thereby preventing the moisture in the gas from adhering to the surface of the speaker 1001 when the gas blown out from the first port 3001 blows downwards against the rainwater on the surface of the speaker 1001. Furthermore, the surface of the speaker 1001 is blown dry by the dry gas blown out from the first port 3001, thereby further enhancing the effect of removing the rainwater on the surface of the speaker 1001 to ensure the sound effect of the speaker 1001.

[0031] Example 2 On the basis of Example 1, Figure 4 and Figure 5 As shown, it also includes a blowing plate 101; the frame of the dustproof mesh cover 2 is set to be hollow inside, and the frame of the dustproof mesh cover 2 is connected to four equidistantly arranged blowing plates 101, and each blowing plate 101 is provided with a plurality of air outlets; an air inlet 2001 is opened on the upper side of the frame of the dustproof mesh cover 2, and a second opening 3002 is opened on the guide plate 3; the second opening 3002 is aligned with the air inlet 2001.

[0032] The blowing plate 101 is inclined toward one side of the speaker 1001 .

[0033] Since there is a concave area in the speaker 1001, when rainwater is located in the concave area of ​​the speaker 1001, it is difficult to blow the rainwater in the area through the wind blowing downward from the first port 3001, so that under the pumping of the cooling fan 5, part of the gas enters the frame of the dustproof mesh cover 2 through the second port 3002 and the air inlet 2001, and then blows out from the air outlet of the blowing plate 101. Since the blowing plate 101 is inclined toward one side of the speaker 1001, the blowing plate 101 can blow air toward the concave area of ​​the speaker 1001 to blow and dry the rainwater in the area, further enhancing the effect of removing rainwater on the surface of the speaker 1001, avoiding the problem that when rainwater is located in the concave area of ​​the speaker 1001, it is difficult to blow the rainwater in the area through the wind blowing downward from the first port 3001, resulting in rainwater accumulating in the concave area of ​​the speaker 1001, thereby preventing rainwater from penetrating into the audio body 1.

[0034] And after the rain stops, the wind blowing obliquely downward through the blowing plate 101 contacts and rebounds the speaker 1001 to form an airflow, which also has a certain drying effect on the dustproof mesh cover 2, and cooperates with the dry gas blown out from the first port 3001 and the blowing plate 101 respectively to achieve rapid drying of the rainwater between the speaker 1001 and the dustproof mesh cover 2, thereby preventing the rainwater from accumulating between the speaker 1001 and the dustproof mesh cover 2 for a long time, causing the area to become moldy. Furthermore, after the rainwater between the speaker 1001 and the dustproof mesh cover 2 is dried, the cooling fan 5 can be controlled to reverse, and the outside air can be drawn into the space between the guide plate 3 and the audio body 1 and the interior of the ventilation duct 4 from the first port 3001, and then blown out from the air inlet 1002 to dry the space between the guide plate 3 and the audio body 1 and the interior of the ventilation duct 4 to avoid mold.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the present invention.
