Description

Technical Field

[0001] This utility model relates to the field of intelligent speaker hardware structure technology, and in particular to an integrated multi-functional intelligent speaker. Background Technology

[0002] Smart speakers are audio devices that integrate artificial intelligence technology, combining voice interaction, music playback, and home control functions. They capture user voice commands through a built-in microphone array, which are then analyzed by cloud-based AI for accurate responses. Their core advantages lie in convenient voice operation and contextualized services, making them an important entry point into the smart home ecosystem. Users can complete various tasks through natural dialogue, improving life efficiency and the technological experience. Currently, in existing smart speakers, 4G communication, WiFi hotspot, and voice interaction modules are mostly independent components with a scattered layout. This results in large speaker sizes, severe internal signal interference, low integration of functional modules, and affects the stability of 4G / WiFi signals and voice pickup effects. Physical button layouts are also disorganized, making operation inconvenient. Furthermore, the concentrated heat generated when multiple modules are working, coupled with an unreasonable heat dissipation structure design, easily leads to device crashes. Utility Model Content

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Example 1:

[0018] Please refer to Figures 1 to 7This utility model discloses an integrated multifunctional smart speaker, comprising a housing head 1, a housing body 2, and a housing base 3. The housing head 1 is hemispherical and houses an OLED display screen 101. Four microphone pickup holes 102 are located on the outside of the housing head 1, each covered with a dustproof mesh 103. A wake-up interruption button 104 is installed on the outside of the housing head 1 and is connected to the OLED display screen 101 via an electrical connection cable. A button area 5 is located on the front of the housing body 2, including an M button and volume buttons. Heat dissipation holes 201 are provided on both sides of the housing body 2. The housing base 3 is disc-shaped and houses a power supply module 302. A USB-C charging port 304 and a SIM card slot 305 are located on the side wall of the housing base 3. A protective silicone pad 303 is bonded to the bottom of the housing base 3. A motherboard 4 is fixedly connected inside the housing body 2. The motherboard 4 includes a control area, a communication area, a voice area, and a power supply area. The control area houses a control chip 401. The system is electrically connected to the OLED display 101, the wake-up interrupt button 104, and the button area 5. The communication area includes a cellular module 402 and a WiFi module 403. The voice area includes a microphone array 404 consisting of four microphones and an audio decoding chip 405. The four microphones are located inside the microphone pickup holes 102, and the audio decoding chip 405 is connected to the speaker 6 inside the housing base 3. The power supply area includes a DC-DC converter 406 and a charging management chip 407. The DC-DC converter 406 and the charging management chip 407 are connected to the power supply module 302 via electrical connection lines, and are connected to the speaker 6 located inside the housing body 2 via electrical connection lines with the audio decoding chip 405. The motherboard 4 is divided into multiple modules, forming a partitioned layout. The communication area is close to the heat dissipation hole 201, the voice area is close to the microphone pickup hole 102, and the control area is located in the center. This reduces signal interference and heat accumulation between modules, improves the stability of 4G / WiFi signals and voice pickup effect, and has high integration and low interference.

[0019] In this embodiment, a heat sink 409 is attached to the rear of the motherboard 4 via a thermally conductive silicone pad 408. The heat sink 409 is fixedly connected inside the housing body 2. The heat sink 409 is a finned aluminum plate. The two ends of the heat sink 409 contact two heat dissipation holes 201 respectively. Through the setting of the heat dissipation holes 201 and the function of the thermally conductive silicone pad 408 and the heat sink 409, the heat of the motherboard 4 can be dissipated more quickly, improving the heat dissipation efficiency of the internal circuit of the speaker.

[0020] In this embodiment, a circular fan cavity 306 with a central cavity structure is provided at the bottom of the housing base 3. A heat dissipation vent 307 is provided at the upper end of the fan cavity 306. The heat dissipation vent 307 is connected to the interior of the housing body 2. An air inlet groove 308 communicating with the fan cavity 306 is provided on the bottom surface of the housing base 3. The air inlet groove 308 is radially and evenly distributed around the fan cavity 306. A cooling fan 7 is installed inside the fan cavity 306. A filter screen is fixedly connected inside the fan cavity 306 and is located below the cooling fan 7. By setting the cooling fan 7, air from the bottom of the housing base 3 is introduced into the fan cavity 306 through the air inlet groove 308 and delivered into the interior of the housing body 2 through the heat dissipation vent 307, so that the air inside the housing body 2 flows. The air flow carries away the heat generated during the operation of the speaker, thereby achieving the function of efficient heat dissipation.

[0021] In this embodiment, the shell head 1 and shell body 2 are connected by screws, and the shell body 2 and shell base 3 are connected by screws, so that the composite shell composed of the shell head 1, shell body 2 and shell base 3 is detachable, which facilitates the maintenance of the internal microphone array and display screen. The composite shell composed of the shell head 1, shell body 2 and shell base 3 has an astronaut shape and is made of ABS+PC composite material, which has both decorative and functional properties. Example 2:

[0022] Based on Embodiment 1, two power sockets 301 are provided on the side of the housing base 3. The power supply module 302 is inserted into the power socket 301, and the inner end face of the power supply module 302 is connected to the inner surface of the power socket 301 by Velcro. The arrangement of the power socket 301 and the power supply module 302 in this structure makes the power supply module 302 easy to disassemble and facilitates the efficient replacement and maintenance of the battery inside the power supply module 302.

[0023] In use, this invention first allows a SIM card to be inserted through the SIM card slot 305, connecting to the network via a communication area consisting of a cellular module 402 and a WiFi module 403. External voice commands are received and detected through the microphone array 404, decoded by the audio decoding chip 405, and then transmitted to the control chip 401 for processing. The signal is then transmitted to the OLED display 101 for synchronous display. The control chip 401 sends a signal to the audio decoding chip 405, controlling the speaker 6 to convert the signal into sound. The smart speaker can be manually controlled via the wake-up interrupt button 104 and the button area 5. During this process, the cooling fan 7 draws air from the bottom of the housing base 3 into the fan cavity 306 through the air inlet slot 308 and delivers it into the housing body 2 through the cooling vent 307, causing airflow inside the housing body 2. This airflow carries away the heat generated during the speaker's operation, achieving efficient heat dissipation.

[0024] All the above components are installed, connected, or set up using common mechanical methods, such as welding, threaded connections, and screw connections. Furthermore, the specific structure, model, and coefficient specifications of all components are based on their own technologies, and any method that achieves the desired effect can be implemented. The OLED display screen 101, speaker 6, cooling fan 7, etc., mentioned above are all common components on the market. When purchasing and using them, simply follow the instructions provided with the purchase to connect them for operation; therefore, further details are omitted here.
