Description

Technical Field

[0001] The utility model relates to the field of sound-generating devices, and in particular to a sound-generating device with active heat dissipation and intelligent monitoring equipment. Background Art

[0002] With the continuous development and progress of current technology, smart homes have been widely used in life, and smart speaker terminal products have also entered the daily life of the public. Smart speakers can play music, voice intercom, emergency rescue and other functions. At present, smart speakers need to be connected to the Internet for voice control, voice Q&A and other functions. In order to connect to the Internet outdoors, it is necessary to place a communication module inside the sound device to access WIFI or 4G, 5G and other networks.

[0003] Since the communication module is a heat source, higher requirements are placed on the heat dissipation effect of the sound-generating device. The prior art generally uses passive heat dissipation, that is, the heat generated by the smart speaker is dissipated through the outside air or the shell. For example, the existing patent with application number CN202020030191.7 mainly uses a circuit board to be set at the upper end of the integrated circuit board through a number of fixed spaces to leave a first heat dissipation gap. A 4G interface is provided on the circuit board, and a pad is protruding upward at one end of the circuit board away from the 4G interface. When the 4G module is plugged into the 4G interface, the end of the 4G module away from the 4G interface and the pad are detachably arranged. At this time, a second heat dissipation gap is left between the 4G module and the circuit board. The playback box effectively improves heat dissipation, thereby extending the service life. The passive heat dissipation method is difficult to meet the heat dissipation requirements of smart speakers equipped with communication modules. If a fan is added, the volume of the smart speaker will increase.

[0004] The purpose of the present invention is to design a sound-generating device and intelligent monitoring equipment with active heat dissipation in view of the above-mentioned problems in the prior art. Utility Model Content

[0036] A housing 1, wherein the housing 1 is provided with a circle of through holes, and the through holes are divided into a heat dissipation area 102 and a sound output area 103 by a surrounding wall 101;

[0037] The sound-generating mechanism 2 includes a rear sound cavity 201 and a speaker 202. The rear sound cavity 201 is disposed in the housing 1. The rear sound cavity is provided with a sound outlet 2011 and a sound leakage hole 2012. The sound leakage hole 2012 is connected to the heat dissipation area 102. The sound outlet 2011 is connected to the sound outlet area 103. The sound outlet end of the speaker 202 is sealed in the sound outlet 2011.

[0038] The control main board 3 is arranged at a position on the rear sound cavity 201 corresponding to the sound leakage hole 2012 .

[0039] In this embodiment, the rear sound cavity 201 and the surrounding wall 101 jointly separate the through holes, and the heat dissipation area 102 and the sound output area 103 are separated and cannot be connected.

[0040] The sound outlet 2011, the speaker 202, and the sound outlet area 103 are connected in sequence. When the speaker 202 is working, the sound is transmitted from the sound outlet area 103 to the outside. Figure 7 The sound leakage hole 2012 allows air to flow in and out of the rear sound cavity 201, which can prevent pressure accumulation in the rear sound cavity 201; the rear sound cavity 201, the sound leakage hole 2012, and the heat dissipation area 102 are connected, and the flowing air generated by the speaker 202 through the sound leakage hole 2012 can actively take away the heat generated by the control motherboard 3 and discharge it from the heat dissipation area 102.

[0041] Furthermore, the shell 1 is a cylindrical structure, the enclosure 101 is an arc-shaped structure cocentric with the shell 1 , the through holes corresponding to the bottom enclosure of the enclosure 101 form the heat dissipation area 102 , and the top of the enclosure 101 opens the heat dissipation area 102 .

[0042] In this embodiment, the heat dissipation area 102 and the sound production area 103 are separated by an arc-shaped wall 101, and the upper end of the heat dissipation area 102 is not blocked and is in an open state, so that air can flow back and forth between the heat dissipation area 102, the control main board 3, the sound leakage hole 2012, and the inside of the rear sound cavity 201, and take away the heat generated by the control main board 3.

[0043] Furthermore, the rear sound cavity 201 is sealed in the space within the housing 1 corresponding to the surrounding wall 101 .

[0044] In this embodiment, the rear sound cavity 201 is sealed in the space within the housing 1 corresponding to the wall 101 by means of glue, thereby isolating the heat dissipation area 102 and the sound production area 103 so that the air flows will not interfere with each other.

[0045] Furthermore, a foot pad 104 is provided at the bottom end of the shell 1 , and the foot pad 104 raises the rear sound cavity 201 so that a gap is provided between the bottom surface of the rear sound cavity 201 and the bottom surface of the shell 1 .

[0046] The foot pad 104 can prevent the bottom of the housing 1 from blocking the sound outlet area 103 , and can also prevent the vibration of the speaker 202 from being disturbed by the bottom of the housing 1 .

[0047] Furthermore, the sound leakage hole 2012 is arranged on the upper end surface of the rear sound cavity 201 .

[0048] Through this structure, the upper end surface of the rear sound cavity 201 can be used to place the control main board 3, and the air flow generated by the sound leakage hole 2012 can directly blow toward the control main board 3, thereby taking away the heat thereof.

[0049] Furthermore, the outer periphery of the bottom end of the shell 1 is chamfered, and the outer periphery of the bottom end of the rear sound cavity 201 is chamfered.

[0050] Furthermore, the control main board 3 is provided with a communication module.

[0051] Furthermore, the communication module is one or more of a WIFI module, a 4G module, and a 5G module.

[0052] Furthermore, the communication module is arranged above the sound leakage hole 2012 .

[0053] Furthermore, the housing 1 comprises an upper housing and a lower housing, the upper housing closes the upper end surface of the lower housing, the upper housing is provided with buttons, and the lower housing is provided with a power supply port.

[0054] The upper shell seals the upper end surface of the lower shell, which can limit the air flow generated by the sound leakage hole 2012 to only flow to the heat dissipation area 102, thereby improving the heat dissipation effect.

[0055] An active heat dissipation intelligent monitoring device is further provided, comprising the active heat dissipation sound-generating device.
