Description

Technical Field

[0001] This invention relates to a sound card, specifically a live streaming sound card. Background Technology

[0002] Live streaming sound cards primarily enhance sound quality, act as adapters (connecting microphones, mobile phones or computers, headphones, etc.), and provide live streaming effects and sound tools. With the development of e-commerce, more and more people are using live streaming sound cards for live commerce. However, current live streaming sound cards have the following drawbacks:

[0003] The live streaming sound card host is placed flat on the table. The top of the host has a large number of control buttons. These control buttons include sound scene switching, voice switching, noise reduction, atmosphere enhancement, etc. These control buttons are arranged in a flat manner. When the user is live streaming, the live streaming device is placed in front of them like a mobile phone. Therefore, there is a 90-degree angle between the control buttons of the live streaming sound card and the mobile phone device. So when the person is facing the mobile phone device during the live stream, they cannot see the control buttons of the host. So if they want to control the buttons, they have to look down to find the corresponding buttons. At this time, the face can only face the host. The mobile phone cannot capture the position of the person's face. If the buttons are frequently used, it will inevitably have a certain impact on the live streaming process.

[0004] In addition, since the live streaming sound card host is not very large, the large number of buttons on the top will cause the buttons to be clustered together, making it difficult to quickly find the corresponding button during live streaming, which is very inconvenient.

[0005] Finally, because the top of the live streaming sound card has a large number of exposed buttons, and the entire live streaming sound card device is directly exposed to the outside world, dust can easily accumulate on the buttons over time, and solid particles can fall in. In addition, if a water cup or other object on the table is knocked over, water can also get into the buttons, resulting in certain safety hazards when using the live streaming sound card. Summary of the Invention

[0006] The technical problem to be solved by this invention is a live streaming sound card. By setting a control panel on the top of the device host to cover all the control buttons, the control panel can be used for unified control. At the same time, the control panel can effectively cover the buttons to achieve waterproof and dustproof effects. By setting up an operating lever, the situation where the person is looking down to find the control buttons during the live broadcast is reduced and cannot face the camera. The distance between each button is dispersed and increased to facilitate finding the corresponding button. This effectively solves many shortcomings of the prior art.

[0007] The present invention is achieved through the following technical solution: a live sound card, including a device host, the upper surface of the device host forms a button control area, the button control area is provided with multiple sliding button groups and pressing button groups, an operation panel is slidably arranged on the upper surface of the button control area, and a button positioning hole is provided on the lower surface of the operation panel corresponding to the sliding button groups and pressing button groups, and the operation panel covers the multiple sliding button groups and pressing button groups at the lower end.

[0008] Each sliding button group is provided with a first lifting button cap, and each pressing button group is provided with a second lifting button cap. When neither the first nor the second lifting button cap is lifted, a gap cavity is formed between the upper surface of the first and second lifting button caps and the lower surface of the operation panel. When both the first and the second lifting button caps are lifted, they are snapped into the button positioning holes.

[0009] The device host has multiple flexible operating levers arranged side by side on the side away from the user. Each operating lever has a button panel on the top facing the operator, and each button panel has button graphics. Each operating lever corresponds to a sliding button group or a pressing button group.

[0010] As a preferred technical solution, each of the button control areas is provided with a horizontal guide groove, and the bottom of the operation panel is provided with two guide sliders corresponding to each guide groove. The guide sliders are slidably inserted into the guide grooves, and the sliding direction of the sliding button group is the same as the sliding direction of the guide sliders.

[0011] As a preferred technical solution, a first spring is fixedly installed on both sides of the guide slide groove, and the other end of the first spring is in elastic contact with one side of the guide slider, so that the operation panel is located in the middle of the guide slide groove by means of the first spring.

[0012] As a preferred technical solution, the cross-sectional shape of the guide slider and the guide groove is "T" shaped. The guide slider includes a support part and a limiting part. One end of the support part is fixedly connected to the lower end face of the operation panel, and the other end of the support part is elastically inserted into the support groove opened on the limiting part. A second spring is fixedly installed on the bottom surface of the support groove, and the other end of the second spring is fixedly bonded to the support part inserted into the support groove.

[0013] As a preferred technical solution, the operating levers are all L-shaped structures composed of horizontal and vertical sections. A mounting port is opened on the main unit of the equipment corresponding to the horizontal section. An air storage bag is fixedly installed at the bottom of the mounting port. One end of the horizontal section is inserted into the mounting port and fixedly injection molded together with the main unit of the equipment. The vertical section extends towards the top of the main unit of the equipment. Each air storage bag is connected to the corresponding sliding button group or pressing button group through an air guide tube. By squeezing the air storage bag, the lifting button cap on the sliding button group or pressing button group is lifted up and snapped into the button positioning hole at the bottom of the operation panel.

[0014] As a preferred technical solution, a support plate is fixedly installed on the main unit of the device located at the bottom of the transverse section. A first magnetic block is fixedly installed on the support plate at the position corresponding to each transverse section. A second magnetic block is fixedly installed on each transverse section corresponding to the first magnetic block. When the transverse section is elastically compressed, the first magnetic block and the second magnetic block attract and restrict the transverse section to reset, so that the air bladder is always in a compressed state. The magnetic attraction force between the first magnetic block and the second magnetic block is greater than the elastic deformation recovery force of the transverse section.

[0015] As a preferred technical solution, each sliding button group includes a sliding key, and each sliding key has a floating cavity with a top opening. The first lifting button cap is floatingly disposed in the floating cavity. The bottom of both the first and second lifting button caps is provided with a lifting airbag. The lifting airbags are connected to the corresponding air storage bladders through air guide tubes. A lifting airbag mounting cavity is provided at the position of the first lifting button cap corresponding to the lifting airbag. The bottom of the lifting airbag is fixedly connected to the bottom surface of the floating cavity, and the top is inserted into the lifting airbag mounting cavity. Limiting sliders are provided on both sides of the first lifting button cap. The limiting sliders are slidably disposed in the longitudinal limiting grooves opened in the inner wall of the floating cavity.

[0016] As a preferred technical solution, a guide slide rod is fixedly installed at the bottom of each sliding key. The air guide tube passes through the hollow guide slide rod and is routed from inside the main unit of the equipment to connect the air storage bag and the lifting air bag. Each sliding key is slidably installed in a sliding keyway. A sliding connector is installed at the bottom of the sliding key. The sliding connector is fixedly connected to the sliding element inside the main unit of the equipment. A slide rod groove is arranged side by side on one side of each sliding keyway on the main unit of the equipment. The guide slide rod is slidably snapped into the slide rod groove.

[0017] As a preferred technical solution, a raised lever is provided on both sides of the upper surface of the control panel.

[0018] As a preferred technical solution, an interface area is provided on one side of the device host, the interface area is provided with multiple interfaces and power wiring, and multiple fixing suction cups are provided on the bottom of the device host.

[0019] The beneficial effects of the present invention are as follows: First, by setting up an operation panel, the present invention covers the sliding button group and pressing button group on the main unit of the device, thereby achieving the purpose of dustproofing and waterproofing, improving service life, and enhancing user experience.

[0020] This invention features multiple control levers on the back of the device host. By utilizing the upward-extending vertical segments, the control levers can be controlled from the front while facing the camera during live streaming, eliminating the need to look down to find buttons. This allows the camera to remain more focused on the operator, enhancing the live streaming experience.

[0021] This invention distributes the control buttons on the main unit of the device to various operating levers. By utilizing the unused space in the air, each control button is distributed and expanded as much as possible, making it easier for the operator to find the corresponding button.

[0022] The entire control panel of this invention is a single control button, which greatly improves the overall size and the feel of operation. Pushing the corresponding control lever will activate the corresponding control button, and the control panel can then perform the corresponding button operation commands.

[0031] All features disclosed in this specification, or all steps in all disclosed methods or processes, may be combined in any way, except for mutually exclusive features and / or steps.

[0032] Any feature disclosed in this specification (including any appended claims, abstract, and drawings) may be replaced by other equivalent or similar features for a similar purpose, unless specifically stated otherwise. That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.

[0033] like Figure 1 and Figure 2 As shown, a live streaming sound card of the present invention includes a device host 1. The upper surface of the device host 1 forms a button control area 2. The button control area 2 is provided with a plurality of sliding button groups 40 and pressing button groups 30. An operation panel 10 is slidably disposed on the upper surface of the button control area 2. A button positioning hole 70 is provided on the lower surface of the operation panel 10 at the position corresponding to the sliding button groups 40 and pressing button groups 30. The operation panel 10 covers the plurality of sliding button groups 40 and pressing button groups 30 at the lower end.

[0034] Each sliding button group 40 is provided with a first lifting button cap 20, and each pressing button group 30 is provided with a second lifting button cap 22. When neither the first lifting button cap 20 nor the second lifting button cap 22 is lifted, a gap cavity is formed between the upper end surface of the first lifting button cap 20 and the lower end surface of the operation panel 10. When both the first lifting button cap 20 and the second lifting button cap 22 are lifted, they are snapped into the button positioning hole 70.

[0035] On the main unit 1 of the device, multiple flexible operating levers are arranged side by side on the side away from the user. Each lever has a button panel 13 on its top facing the operator, and each button panel 13 displays button graphics 16. Each lever corresponds to a sliding button group 40 or a pressing button group 30, such as... Figure 2 As shown, the present invention extends multiple operation sensors to the outer end of the device host 1, so that the external unused area can be used to arrange the button graphics 16, so that the button graphics 16 can not only be enlarged, but also the gap between the button graphics 16 can be enlarged, making it easier to find the corresponding button and perform more efficient operation.

[0036] Among them, such as Figure 3 As shown, each of the button control areas 2 is provided with a horizontal guide groove 12. The bottom of the operation panel 10 is provided with two guide sliders 9 corresponding to each guide groove 12. The guide sliders 9 are slidably inserted into the guide groove 12. The sliding direction of the sliding button group 40 is the same as the sliding direction of the guide sliders 9. The operation of the sliding button group 40 itself is a horizontal reciprocating operation, such as many push-pull control buttons, which are adjusted by pushing. This invention uses the control method of this type of control button. The operation panel 10 of this invention can slide left and right along the guide groove 12, which is the same as the left and right sliding method of the sliding button group 40. Therefore, when the top of the sliding button group 40 is in contact with the limit of the operation panel 10, controlling the left and right sliding of the operation panel 10 can realize the left and right sliding control of the sliding button group 40, so as to achieve the purpose of controlling the operation panel 10 to operate the sliding button group 40.

[0037] In this device, a first spring is fixedly installed on both sides of the guide slide 12. The other end of the first spring is in elastic contact with one side of the guide slider 9. The first spring is used to make the operation panel 10 located in the middle of the guide slide 12. The main function of the first spring is to reset the operation panel 10. After the operation panel 10 is pushed horizontally, the elastic force of the first spring is used to achieve the purpose of reset, so as to facilitate the operation of the next button.

[0038] like Figure 5As shown, the cross-sectional shape of the guide slider 9 and the guide groove 12 is "T" shaped. The guide slider 9 includes a support part 90 and a limiting part. One end of the support part 90 is fixedly connected to the lower end face of the operation panel 10, and the other end of the support part 90 is elastically inserted into a support groove opened on the limiting part. A second spring is fixedly installed on the bottom surface of the support groove, and the other end of the second spring is fixedly bonded to the support part 90 inserted into the support groove. During normal installation, the guide slider 9 is supported by the limiting part at the bottom. At this time, the second spring is in a normal rebound state. Therefore, as long as the operation panel 10 is not pressed down, the second spring will not be compressed. The operation panel 10 does not change in height. Therefore, when the sliding button group 40 is pushed horizontally back and forth, the operation panel 10 does not change in height, and the second spring is not compressed. At this time, the sliding operation of the sliding button group 40 is performed. However, when it is necessary to operate the pressing button group 30, simply press down on the operation panel 10 to make the support part 90 move relative to the limiting part, thereby squeezing the second spring and compressing it. Pressing down on the operation panel 10 at this time means pressing down on the pressing button group 30, thus achieving the pressing action of the pressing button group 30.

[0039] like Figure 1 As shown, the operating levers are all L-shaped structures composed of a horizontal segment 8 and a vertical segment 14. A mounting port is opened on the main unit 1 corresponding to the horizontal segment 8. An air reservoir 7 is fixedly installed at the bottom of each mounting port. One end of the horizontal segment 8 is inserted into the mounting port and fixedly injection molded together with the main unit 1. The vertical segment 14 extends towards the top of the main unit 1. Each air reservoir 7 is connected to the corresponding sliding button group 40 or pressing button group 30 via an air guide tube 25. Squeezing the air reservoir 7 causes the lifting button caps on the sliding button group 40 or pressing button group 30 to rise and fall. The lever is lifted and snapped into the button positioning hole 70 at the bottom of the control panel 10. Therefore, when the horizontal section 8 on the lever does not compress the air bladder 7, the first lifting button cap 20 and the second lifting button cap 22 will not be lifted and will not snap into the button positioning hole 70. So, when the lever is not pushed, the control panel 10 will not have any button action. Only when the corresponding lever is pushed manually and the corresponding air bladder 7 is compressed will the lifting button cap at the corresponding button be lifted. At this time, the control panel 10 can operate the corresponding control button.

[0040] like Figure 1As shown, a support plate 6 is fixedly installed on the main unit 1 at the bottom of the transverse segment 8. A first magnetic block 5 is fixedly installed on the support plate 6 at the position corresponding to each transverse segment 8. A second magnetic block 15 is fixedly installed on each transverse segment 8 corresponding to the first magnetic block 5. When the transverse segment 8 is elastically compressed, the first magnetic block 5 and the second magnetic block 15 attract and restrict the transverse segment 8 to return to its original position, so that the air bladder 7 is always in a compressed state. The magnetic attraction force between the first magnetic block 5 and the second magnetic block 15 is greater than the elastic deformation recovery force of the transverse segment 8. When the longitudinal segment 14 is pushed, the transverse segment 8 will deform, so that the first magnetic block 5 relative to the second magnetic block 15 will be compressed. The movement of the suction block 15 causes the air reservoir 7 to be compressed, and the first magnetic suction block 5 and the second magnetic suction block 15 are attracted together. At this time, the air reservoir 7 is in a continuous state of compression, and the gas in the corresponding air reservoir 7 is squeezed out into the corresponding lifting air 31, which causes the lifting air 31 to lift the corresponding lifting button cap. After the lifting button cap is lifted, it is snapped into the button positioning hole 70. At this time, the control panel 10 can perform the corresponding button operation. After the operation is completed, the operating lever is manually turned back to separate the first magnetic suction block 5 and the second magnetic suction block 15, so that the gas in the lifting air 31 can flow back into the air reservoir 7, and the lifting button cap is reset.

[0041] like Figure 4 As shown, each sliding button group 40 includes a sliding button 19. Each sliding button 19 has a floating cavity 28 with a top opening. The first lifting button cap 20 is floatingly disposed in the floating cavity 28. The bottom of both the first lifting button cap 20 and the second lifting button cap 22 is provided with a lifting airbag 31. The lifting airbag 31 is connected to the corresponding air storage bag 7 through the air guide tube 25. The first lifting button cap 20 is provided with a lifting airbag 31 mounting cavity 29 at the position corresponding to the lifting airbag 31. The bottom of the lifting airbag 31 is fixedly connected to the bottom surface of the floating cavity 28, and the top is inserted into the lifting airbag 31 mounting cavity 29. The first lifting button cap 20 is provided with limit sliders 23 on both sides. The limit sliders 23 are slidably disposed in the longitudinal limit grooves 32 opened in the inner wall of the floating cavity 28. When the lifting airbag 31 is filled with gas from the air storage bag 7, the lifting airbag 31 inflates and expands, causing the entire lifting button cap to rise.

[0042] Each sliding key 19 has a guide rod 24 fixedly installed at its bottom. An air duct 25 passes through the hollow guide rod 24 and is routed from inside the main unit 1 to the air storage bladder 7 and the lifting air bladder 31. Each sliding key 19 is slidably installed in a sliding key 19 groove 18. A sliding connector 27 is provided at the bottom of the sliding key 19. The sliding connector 27 is fixedly connected to the sliding element inside the main unit 1. A sliding rod groove 17 is arranged side by side on one side of each sliding key 19 groove 18 on the main unit 1. The guide rod 24 slides into the sliding rod groove 17. The sliding key 19 slides left and right in the sliding key 19 groove 18 to realize the button adjustment function. The guide rod 24 slides left and right with the sliding key 19 in the sliding rod groove 17. In order to follow the movement, the air duct 25 is provided with a spring connecting section 26, which can realize the pulling. The left and right sliding of the sliding key 19 drives the sliding connector to slide left and right, thereby driving the left and right sliding displacement of the sliding element to realize the purpose of button sliding adjustment. Therefore, during operation, simply push the corresponding function lever to compress the air reservoir 7, causing the corresponding button group to rise. After it rises, the control panel 10 can be used to adjust left and right or press down, which is very convenient.

[0043] The structure of the press button group 30 is similar to that of the slide button group 40. The difference is that the press button group 30 is press-controlled, while the slide button group 40 is slide-controlled. Therefore, the press button group 30 is not located within the slide button 19 slot 18; it achieves the pressing purpose through downward drive. Thus, when the second lifting button cap 22 is not raised, pressing down on the operation panel 10 will not touch the press button group 30. Only after the second lifting button cap 22 is inflated and raised, at which point the top of the second lifting button cap 22 contacts the bottom of the operation panel 10, and pressing down on the operation panel 10 at this point will press down the entire press button group 30, achieving the control purpose.

[0044] To facilitate operation of the control panel 10, a protruding lever 11 is provided on both sides of the upper surface of the control panel 10. The lever 11 is used to drive the control panel 10 to move left and right, thereby enabling the sliding button group 40 to slide left and right.

[0045] The device host 1 has an interface 3 area on one side, which has multiple interfaces 3 and power wiring. The device host 1 has multiple suction cups 4 on the bottom.

[0046] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
