[0002] Smart control panels are an important component of smart homes, used to enable intelligent control of electrical equipment and improve home comfort.

[0003] Some existing smart control panels are equipped with sound-generating devices for sound output. These existing smart control panels use integrated sound-generating devices, which integrate a speaker and a sound cavity. They are small in size but expensive. Moreover, because there are many components that need to be installed inside the smart control panel, the installation space for the integrated sound-generating device is small. Therefore, the integrated sound-generating devices of existing smart control panels are all small-volume integrated sound-generating devices with only one sound cavity. The sound cavity of this small-volume integrated sound-generating device is also very small. This results in low volume and poor sound quality of the sound output from the smart control panel.

[0043] To further explain the technical solution of the present invention, the present invention will be described in detail below through specific embodiments.

[0044] like Figures 1 to 5 As shown, the present invention discloses an intelligent control panel, which includes a sound-generating structure. The sound-generating structure includes a panel body 1 and a speaker 2. A control board 3 is provided inside the panel body 1. The panel body 1 forms a front sound cavity 101, a rear sound cavity 102, and a speaker mounting cavity 103 connecting the front sound cavity 101 and the rear sound cavity 102. The panel body 1 is provided with a sound outlet 104 communicating with the front sound cavity 101. The speaker 2 is mounted in the speaker mounting cavity 103 and is electrically connected to the control board 3. An isolation member 4 is provided between the speaker 2 and the speaker mounting cavity 103 to isolate the front sound cavity 101 and the rear sound cavity 102. The control board 3 controls the operation of the speaker 2. The sound-emitting parts on the front and rear sides of the speaker 2 emit sound from the front sound cavity 101 and the rear sound cavity 102, respectively.

[0045] In the sound-emitting structure of the intelligent control panel of the present invention, the panel body 1 is provided with a separated front sound cavity 101 and a rear sound cavity 102, and a sound outlet 104 communicating with the front sound cavity 101. The sound-emitting parts on the front and rear sides of the speaker 2 emit sound from the front sound cavity 101 and the rear sound cavity 102 respectively. The front sound cavity 101 can improve the high-frequency sound of the speaker 2, and the rear sound cavity 102 can improve the low-frequency sound of the speaker 2, thereby effectively improving the sound quality and volume of the intelligent control panel. In addition, the present invention can directly use an ordinary speaker 2 to emit sound. The price of an ordinary speaker 2 is lower than that of existing integrated sound-emitting devices, which can effectively reduce the cost of the intelligent control panel. Specifically, the speaker 2 can be a low-cost dynamic speaker.

[0046] Cooperate Figures 1 to 5 As shown, the panel body 1 may specifically include a front shell 11, a front shell 12, and a front shell cover 13; wherein, the front shell 11 and the front shell cover 13 are respectively installed on the front and rear sides of the front shell 12, the front sound cavity 101 is located between the front shell 11 and the front shell 12, the rear sound cavity 102 is located between the front shell 12 and the front shell cover 13, and the speaker mounting cavity 103 includes a through hole 1031 disposed in the front shell 12; the present invention is configured in this way to make full use of the structural space of the panel body 1 to set the front sound cavity 101, the rear sound cavity 102, and the speaker mounting cavity 103, so that the intelligent control panel of the present invention improves the sound quality while being more compact and smaller in size.

[0047] Specifically, the front shell 12 is provided with a mating part 121 having a forward-protruding baffle 1211. A front sealing gasket 14 is sandwiched between the baffle 1211 and the front shell 11. The mating part 121 of the front shell 12 and the front shell 11 form the front sound cavity 101. The sealing gasket 14 can prevent sound leakage from the front sound cavity 101, thereby ensuring the high-frequency sound output effect of the speaker. A side opening is provided on the side of the baffle 1211. The side opening of the baffle 1211 and the front shell 11 form the sound outlet 104 (i.e., the sound outlet 104 is formed between the front shell 12 and the front shell 11), so that the intelligent control panel of the present invention emits sound from the side. The front shell 11 is provided with an output channel 105 communicating with the sound outlet 104, which makes the sound emitted by the intelligent control panel of the present invention louder. It should be noted that the sound outlet 104 is not limited to being located between the front shell 12 and the front shell 11. The sound outlet 104 can also be directly located on the front shell 11, so that the intelligent control panel of the present invention emits sound from the front.

[0048] Cooperate Figures 2 to 5As shown, the control board 3 can be installed between the front shell 12 and the front shell cover 13. The control board 3 can be connected to the front shell 12 by screws. The rear sound cavity 102 is formed between the control board 3 and the front shell cover 13. The speaker mounting cavity 103 also includes a through hole 1032 provided in the control board 3, which is opposite to the through hole 1031. This arrangement of the present invention is beneficial for setting a control board 3 with a large area, thereby facilitating the placement of electronic components on the control board 3. The front shell cover 13 can be connected to the front shell 12 by mechanical connection such as screws. The front shell cover 13 forms a rearward recessed groove 131. A rear sealing gasket 15 is sandwiched between the periphery of the groove 131 and the control board 3. The rear sound cavity 102 is formed between the groove 131 of the front shell cover 13 and the control board 3. The rear sealing gasket 15 can ensure that the rear sound cavity 102 is sealed and prevent sound leakage from the rear sound cavity 102, thus ensuring the low-frequency sound effect of the speaker 2. The speaker 2 can pass through the through hole 1032. The isolation member 4 is sandwiched between the periphery of the through hole 1031 and the front side of the speaker 2. The isolation member 4 can be a washer with a spring. The isolation member 4 can effectively improve the sound quality. A speaker gasket 21 is provided between the speaker 2 and the front cover plate 13 to support the speaker 2. The speaker gasket 21 also has a shock absorption function, which helps to improve the sound quality of the intelligent control panel of the present invention.

[0049] Cooperate Figures 2 to 4 As shown, the intelligent control panel of the present invention also includes a microphone 5 electrically connected to the control board 3; the microphone 5 is installed inside the panel body 1, and the panel body 1 has a pickup hole 106 corresponding to the microphone 5. The control board 3 collects the user's voice through the microphone 5 to obtain the user's voice commands, and then the control board 3 executes corresponding operations according to the voice commands, thereby realizing the voice control function; the pickup hole 106 can be set on the face shell 11 of the panel body 1, and the pickup hole 106 is arranged through the front and back, while the sound outlet 104 and the pickup hole 106 can be arranged intersecting, which can avoid reducing the possibility of sound emitted by the speaker 2 being transmitted back to the microphone 5, thereby improving the stability of the voice control function; preferably, the sound outlet 104 and the pickup hole 106 are arranged perpendicularly. The microphone 5 can be connected to the face shell 11 to fix the microphone 5.

[0050] Cooperate Figures 2 to 5As shown, the intelligent control panel of the present invention may further include a light-emitting device 6 and a light guide 7; the light-emitting device 6 and the light guide 7 are disposed in the panel body 1, and the light guide 7 is used to guide the light emitted by the light-emitting device 6 to the output channel 105 for output. Whether the light-emitting device 6 emits light or not can be controlled by the control board 3, and the light-emitting state of the light-emitting device 6 can be used to indicate the position and working status of the intelligent control panel of the present invention; the present invention places the light-emitting device 6 and the light guide 7 inside the panel body 1, which helps to improve the overall appearance of the intelligent control panel of the present invention. The light-emitting device 6 can be offset from the outer opening of the output channel 105, so that the user will not see the light-emitting device 6 when looking directly at the outer opening of the output channel 105, thus improving the user's viewing experience. The output channel 105 may have a first reflective surface 1051 and a second reflective surface 1072 arranged opposite to each other. The light emitted by the light-emitting device 6 is first guided to the first reflective surface 1051 by the light guide 7, then reflected by the first reflective surface 1051 to the second reflective surface 1052, and finally reflected by the second reflective surface 1052 before being output through the output channel 105. This allows adjustment of the brightness of the light emitted by the light-emitting device 6 and the angle at which the light is output through the output channel 105, thereby making the light output through the output channel 105 soft and easy for the user to view; in conjunction with Figure 4 and Figure 5 As shown, the first reflective surface 1051 can be tilted at 45°, and the first reflective surface 1051 can be treated with a mirror-like high-brightness finish to make the first reflective surface 1051 have a high reflectivity to light.

[0051] Cooperate Figures 1 to 5 As shown, the panel body 1 has a shell 11 that may include a shell body 111 and a cover 112. The shell body 111 is provided with a mating hole 1111, and the cover 112 is disposed in the mating hole 1111. The gap between the cover 112 and the shell body 111 forms the output channel 105. The output channel 105 has an annular structure, and the light-emitting device 6 includes a plurality of light-emitting lamp beads 61 distributed in an annular structure. Each light-emitting lamp bead 61 is electrically connected to the control board 3. The light guide 7 has an annular structure and is opposite to each light-emitting lamp bead 61. With this arrangement, the light emitted by the light-emitting device 6 can form an annular aperture after being output from the output channel 105, resulting in a good display effect. The main body 111 and the cover 112 can be connected to the front shell 12. The light guide 7 can be connected to the front shell 12 by mechanical connection such as snap-fit. The light guide 7 can be provided with two reflective surfaces to reflect the light emitted by the light-emitting device 6. Each light-emitting lamp bead 61 of the light-emitting device 6 can be directly welded to the control board 3 to simplify the structure of the present invention. The front shell 12 is provided with light-transmitting holes 122 corresponding to each light-emitting lamp bead 61. The front shell 12 can be provided with a baffle 123 located inside the light guide 7 to reduce light leakage.

[0052] Cooperate Figure 2As shown, the intelligent control panel of the present invention may further include a button 8 electrically connected to the control board 3. The main body 111 of the faceplate 11 is movably fitted to the front shell 12. The main body 111 of the faceplate presses the button 8, and the user inputs commands to the control board 3 by pressing the button 8 through the main body 111 of the faceplate. The main body 111 of the faceplate 11 may be provided with a snap 1112 that can be movably hooked to the front shell 12 so that the main body 111 of the faceplate 11 and the front shell 12 are movably fitted. The face cover 112 of the faceplate 11 can be connected to the front shell 12 by screws. The screws connecting the face cover 112 and the front shell 12 are built into the panel body 1 to ensure the appearance integrity of the panel body 1. The button 8 can be welded to the control board 3, and the front shell 12 is provided with a button hole 124 corresponding to the button 8.
