DETAILED DESCRIPTION

[0033] In order to make the technical problems solved by this application, the technical solutions adopted, and the technical effects achieved more clearly, the technical solutions of the embodiments of this application are further described in detail below. Obviously, the described embodiments are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of this application.

[0034] In the description of this application, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0035] In the present application, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0036] For some acoustic devices, their power consumption is relatively high and they generate a lot of heat. The heating of the components inside the device can easily affect its service life. In the related art, when the internal space of acoustic equipment is insufficient, metal shells are generally used for heat dissipation. However, this makes the user feel hot when picking up the device, thus reducing the user experience. For example, for conference microphone equipment, its size is small and easy to move. It is usually not fixed in a specific position during a meeting. When it is necessary to speak to different people, the user needs to grab the conference microphone device to pass it, which is easy to get hot and affect the user experience.

[0037] Based on the above situation, please refer to Figure 1 and Figure 2 The utility model proposes an acoustic device, including a shell 1, a base 2 and a circuit board assembly 4. The top surface or side surface of the shell 1 is provided with a sound hole 111. The base 2 includes a metal part 21 and a heat insulating part 22. The metal part 21 is arranged at the bottom of the shell 1. The metal part 21 and the shell 1 are enclosed to form an installation cavity 3. The heat insulating part 22 is arranged on the side of the metal part 21 facing away from the installation cavity 3. The circuit board assembly 4 is installed in the installation cavity 3, and the side of the metal part 21 facing the installation cavity 3 is thermally connected to the circuit board assembly 4.

[0038] It is understandable that the acoustic device can be a conference microphone device, a video projection device, an audio device, an intelligent interactive device, etc., which is not limited here. The housing 1 and the metal member 21 are connected and enclosed to form a mounting cavity 3, and the connection method can be a snap connection, a threaded connection, or a plug-in connection, etc., which improves the convenience of assembly and disassembly and facilitates maintenance operations. In one embodiment, if Figure 1 As shown, the housing 1 includes an upper housing 11 and a middle housing 12, the upper housing 11 is connected to the upper part of the middle housing 12, and the metal part 21 is connected to the lower part of the middle housing 12, that is, the metal part 21 is located at the bottom of the housing 1 to form a base of the housing 1, which can carry the circuit board assembly 4 and other components in the mounting cavity 3. At the same time, the metal part 21 can absorb and store the heat generated by the circuit board assembly 4 when it is working by thermal connection with the circuit board assembly 4, which can effectively prevent the heat from being concentrated on the circuit board assembly 4. The heat conduction of the metal part 21 increases the heat dissipation area, facilitates heat dissipation, and prolongs the service life of the circuit board assembly 4. In addition, setting the metal part 21 at the bottom where the user is not easy to touch is conducive to improving the user experience.

[0039] It should be noted that the heat-conducting connection refers to a connection method in which the circuit board assembly 4 can conduct heat to the metal member 21. For example, the metal member 21 is arranged adjacent to the circuit board assembly 4, or a heat-conducting column is protruded on the metal member 21, and the heat-conducting column extends to the adjacent circuit board assembly 4, so that the heat-conducting column receives the heat emitted from the circuit board assembly 4. For another example, the metal member 21 is connected to the circuit board assembly 4 through the heat-conducting connector 6 and the heat-conducting silicone grease, and the heat emitted by the circuit board assembly 4 can be conducted to the metal member 21 through the heat-conducting connector 6 and the heat-conducting silicone grease.

[0040] Optionally, the shell 1 is made of plastic to avoid the situation where the user's hands are burned when grabbing it. When grabbing the acoustic device, the user's hand touches the side wall and bottom wall of the acoustic device. The side wall of the acoustic device is a plastic shell 1, and the bottom wall has a heat insulation 22, which has an anti-scalding effect. In other words, the heat generated by the circuit board assembly 4 is dispersed to the metal part 21 for heat dissipation, and the heat insulation 22 is attached to the outer wall of the metal part 21 to prevent scalding. It can take into account the feeling of not being hot to the hand, and can also gradually dissipate the heat outward to avoid the high heat of the circuit board assembly 4. In other embodiments, the material of the shell 1 can also be metal. In addition, the shell 1 can also be connected to the circuit board assembly 4 through thermal conduction to improve the heat dissipation performance. In this way, the heat insulation 22 can also be coated on the outside of the shell 1 to take into account the effects of heat dissipation and anti-scalding.

[0041] It is understandable that a sound hole 111 is provided on the top or side of the housing 1, and the sound hole 111 is connected to the mounting cavity 3 for the acoustic device to receive or emit sound. Optionally, the sound hole 111 is a plurality of small holes, which ensures the sound effect and prevents the sound hole 111 from being too large and causing foreign matter to enter the mounting cavity 3. It is understandable that the circuit board assembly 4 is installed at the bottom of the mounting cavity 3, so that it is convenient to dissipate heat to the outside through the metal part 21 at the bottom; at the same time, the space above the circuit board assembly 4 is used to assemble components such as speakers, so that it is convenient to emit sound from the top or side of the housing 1.

[0042] Exemplarily, the metal part 21 can be made of aluminum, copper, etc., which has low cost and good thermal conductivity. Here, die-cast aluminum is taken as an example. Of course, the metal part 21 can also be made of other metal materials, which is not limited here. The thermal insulation part 22 is a material with a smaller thermal conductivity than metal, such as plastic, rubber, silicone, etc., which is not limited here. Taking the thermal insulation part 22 as a silicone layer as an example, both the metal part 21 and the thermal insulation part 22 can be completed by silicone molding or liquid silicone injection molding process. Of course, the metal part 21 and the thermal insulation part 22 can also be connected by bonding, clamping or screw connection, which is not limited here.

[0043] The present application connects the housing 1 and the base 2 through the metal part 21 to enclose and form an installation cavity 3 for installing the circuit board assembly 4, and the circuit board assembly 4 is prone to heat during operation. To this end, the side of the metal part 21 facing the installation cavity 3 is thermally connected to the circuit board assembly 4, and the heat generated by the circuit board assembly 4 can be dispersed and thermally conducted through the metal part 21 to avoid the heat being concentrated on the circuit board assembly 4 and affecting its service life. The metal part 21 is arranged at the bottom of the housing 1, that is, the heat generated by the circuit board assembly 4 is conducted to the bottom of the housing 1, which is not easy for the user to touch. At the same time, the heat insulation part 22 is arranged on the side of the metal part 21 facing away from the installation cavity 3 to prevent the user from directly touching the hotter metal part 21, which has an anti-scalding effect and effectively improves the user's experience. In addition, the circuit board assembly 4 can be arranged at the bottom of the installation cavity 3, adjacent to the metal part 21, so that the circuit board assembly 4 can conduct heat to the metal part 21. In addition, the space above the circuit board assembly 4 is reserved for installing acoustic components such as microphones and speakers, and the top surface or side surface of the housing 1 is provided with sound holes 111, so that the acoustic components can receive or emit sound corresponding to the sound holes 111. It should be noted that the heat insulating member is used as a scalding protection member, as long as the thermal conductivity of the heat insulating member 22 is smaller than that of the metal member 21, so that the high thermal conductivity of the metal member 21 is used for heat absorption and heat conduction inside, and the heat insulating member 22 is added outside the metal member 21, so that the user can touch the heat insulating member 22 instead of the metal member 21, so that the hand temperature is reduced when touching, which has an anti-scalding effect.

[0044] Please refer to Figure 2 and Figure 6 In one embodiment, in order to facilitate the circuit board assembly 4 to conduct heat to the metal part 21, a heat-conducting boss 211 is convexly provided on the side of the metal part 21 facing the installation cavity 3. The heat-conducting boss 211 extends into the installation cavity 3 and is thermally connected to the circuit board assembly 4. It can be understood that the heat-conducting boss 211 extends to the adjacent circuit board assembly 4 to reduce the distance between the two and facilitate the thermal connection between the two. The heat-conducting boss 211 can be a prism or a cylindrical boss, which is not limited here. One end of the heat-conducting boss 211 extends to the main heating part of the circuit board assembly 4 to conduct heat in a targeted manner and improve the thermal conductivity efficiency. The heat-conducting boss 211 and the metal part 21 can be an integrally formed structure to reduce the installation steps, that is, the heat-conducting boss 211 is also made of metal to improve the thermal conductivity efficiency. Of course, in other embodiments, the heat-conducting boss 211 can also be connected to the metal part 21 by bonding, welding, clamping or threaded connection.

[0045] In one embodiment, the circuit board assembly 4 has an electronic device, the heat-conducting boss 211 extends toward the electronic device, and the heat-conducting boss 211 is connected to the electronic device through the heat-conducting material 7. It should be noted that the electronic device generates heat when in use.

[0046] It is understandable that when the circuit board assembly 4 is working, it is mainly the electronic components installed on the circuit board that generate heat. The electronic device may be a central processing unit, which generates heat more seriously. Exemplarily, the orthographic projection of the heat-conducting boss 211 on the metal part 21 at least partially overlaps with the orthographic projection of the electronic device on the metal part 21. Optionally, the orthographic projection of the heat-conducting boss 211 on the metal part 21 covers the orthographic projection of the electronic device on the metal part 21. In this way, one end of the heat-conducting boss 211 is adjacent to the electronic device, and the end surface area of ​​the heat-conducting boss 211 is larger than the area of ​​the side of the electronic device adjacent to the heat-conducting boss 211, so that the heat-conducting boss 211 covers the electronic device for heat conduction, thereby improving the heat conduction efficiency.

[0047] The circuit board assembly 4 includes a main control board 41 and a terminal board 42. The main control board 41 is electrically connected to the terminal board 42, and the two can be arranged in parallel to save installation space. The main control board 41 is integrated with a control component, such as a central processing unit, and the terminal board 42 is integrated with a terminal interface for plugging in terminals and connecting to the outside. Optionally, the terminal board 42 is located below the main control board 41, that is, the terminal board 42 is arranged adjacent to the metal member 21, so that the terminal interface on the terminal board 42 can be routed through the metal member 21. It can be understood that the terminal board 42 is annular, and the central processing unit of the main control board 41 is located at the center of the main control board 41. The hole in the middle of the annular terminal board 42 is used for avoidance, so that the heat-conducting boss 211 on the metal member 21 extends through the terminal board 42 to the central processing unit of the main control board 41, which is convenient for heat conduction.

[0048] like Figure 3 As shown, in order to improve the heat conduction efficiency, the heat-conducting boss 211 and the electronic device are connected by the heat-conducting material 7, and the heat-conducting boss 211 extends to the adjacent electronic device. There is a gap between the heat-conducting boss 211 and the electronic device, and the gap is filled by the heat-conducting material 7. The heat-conducting material 7 is an insulating material to prevent the electronic device from short-circuiting. In this way, the electronic device can conduct heat to the heat-conducting boss 211 through the heat-conducting material 7. The heat-conducting material 7 can be heat-conducting silica gel or heat-conducting grease. The heat-conducting material 7 is mainly used to fill the micro gaps and uneven surfaces generated when the heat-conducting boss 211 is adjacent to the electronic device, reduce thermal resistance, and improve heat dissipation performance.

[0049] Please refer to Figure 1 and Figure 6In one embodiment, the circuit board assembly 4 has a plurality of electronic devices, and the metal part 21 is provided with a plurality of heat-conducting bosses 211, and each heat-conducting boss 211 extends to a corresponding electronic device. It can be understood that the plurality of electronic devices on the circuit board assembly 4 correspond to the heat-conducting bosses 211 for heat conduction to improve the heat conduction effect. The connection method between each heat-conducting boss 211 and the electronic device is the same as the above method, which will not be repeated here. It should be noted that the position and height of each electronic device are different, and the corresponding heat-conducting boss 211 is adapted to adjust the position and the height of the boss so that each heat-conducting boss 211 extends to face the electronic device. Exemplarily, the main control board 41 and the terminal board 42 are both provided with electronic devices, and the metal part 21 is provided with a plurality of heat-conducting bosses of different heights according to the different distances between itself and the main control board 41 and the terminal board 42.

[0050] like Figure 6 As shown, in one embodiment, the metal member 21 is further provided with a heat-conducting connection column 212 protruding toward the installation cavity 3, and the heat-conducting connection column 212 is used to fix the circuit board assembly 4. The heat-conducting connection column 212 is a stud, which can be connected to the heat-conducting connection column 212 by passing a screw through a threaded hole on the circuit board assembly 4 to fix the circuit board assembly 4. In this way, by fixing the circuit board assembly 4 through the heat-conducting connection column 212, the distance between the metal member 21 and the circuit board assembly 4 can be effectively controlled, mainly controlling the distance between the heat-conducting boss 211 and the electronic device on the circuit board assembly 4, so as to realize the positioning and installation of the circuit board assembly 4. At the same time, the heat-conducting connection column 212 can also conduct part of the heat on the circuit board assembly 4, thereby improving the heat conduction efficiency.

[0051] In one embodiment, the thermally conductive connecting column 212 is a metal connecting column. It is understandable that the thermally conductive connecting column 212 is integrally formed with the metal member 21 to reduce the number of installation steps and improve the connection stability. The use of metal material can improve the connection strength and the thermal conductivity efficiency. Of course, the metal connecting column and the metal member 21 can also be connected by bonding, clamping, welding or threaded connection, which is not limited here. Optionally, the metal member 21 is provided with at least two thermally conductive connecting columns 212, and the two metal connecting columns are spaced apart to support different positions of the circuit board assembly 4 and improve the installation stability.

[0052] Please refer to Figure 5 and Figure 7In one embodiment, the side of the seat body 2 facing away from the housing 1 is concavely formed with a groove 23, and the side of the seat body 2 facing the installation cavity 3 is formed with a protrusion, which is connected to the circuit board assembly 4 and can be used to support the circuit board assembly 4. The side wall of the groove 23 is provided with a wiring port 24, which connects the groove 23 and the installation cavity 3. The circuit board assembly 4 is provided with a connection terminal, which is arranged corresponding to the wiring port 24. The connection terminal can be but not limited to a USB terminal, a Type-c terminal, or a Lightning terminal. The connection terminal is used to connect with the wire of the external device to realize the interconnection between the acoustic device and the external device, so as to realize the functions of charging and data transmission. It can be understood that the metal part 21 and the heat insulation part 22 are both provided with a groove 23, and the groove 23 can be used as the outlet space for the external wiring of the acoustic device. The side wall of the groove 23 is provided with a wiring port 24, so that the external connection line can extend from the wiring port 24 into the installation cavity 3 and connect with the circuit board assembly 4. Exemplarily, the circuit board assembly 4 is provided with an interface device, and the interface device is arranged corresponding to the wiring port 24 to facilitate the connection of external power lines, signal lines, etc. Optionally, the side wall of the groove 23 is provided with a plurality of wiring ports 24, and the plurality of wiring ports 24 correspond to different interface devices on the circuit board assembly 4 to adapt to connecting different wires. In addition, the groove 23 is formed on the side of the seat body 2 facing away from the housing 1 to prevent the bottom of the seat body 2 from being completely attached to the table, which is conducive to heat dissipation of the seat body 2.

[0053] Specifically, the side of the seat body 2 facing away from the housing 1 is concave to form a groove 23, and the side of the seat body 2 facing the housing 1 is formed with a bulge, so that the metal part 21 is close to the circuit board assembly 4 for heat conduction.

[0054] In one embodiment, based on the arrangement of the metal piece 21 near the bottom of the circuit board assembly 4, the wiring port 24 is arranged at the bottom. In this way, when the product is placed on a desktop or other location for use, the wiring port 24 cannot be seen from the appearance of the product. In this way, the base 2 also has the function of hiding the wiring port 24.

[0055] like Figure 7 As shown, in one embodiment, a wiring groove 25 is provided on the side of the seat body 2 facing away from the shell body 1, one end of the wiring groove 25 is connected to the groove 23, and the other end extends to the edge of the seat body 2. It can be understood that the metal member 21 and the heat insulating member 22 are both formed to form the wiring groove 25 to serve as a wiring space for the external wiring of the acoustic device, that is, the wire connected to the wiring port 24 in the groove 23 is led out from the wiring groove 25 and connected to an external power source or an external device. The wiring groove 25 can provide space for accommodating the wires to avoid the acoustic device pressing on the wires.

[0056] In one embodiment, at least two wiring grooves 25 are provided on the side of the seat body 2 facing away from the shell 1, and at least two wiring grooves 25 are arranged at intervals. Different connecting wires can be led out through the wiring grooves 25 at different positions to improve adaptability. At the same time, the user can also choose to use one of the wiring grooves 25 for wiring as needed to improve the user experience. In addition, the wiring groove 25 is connected to the groove 23. When the acoustic device is placed on the table, part of the bottom wall of the seat body 2 is spaced from the table, which is conducive to the heat dissipation of the seat body 2. In other words, the groove 23 at the bottom of the seat body 2 and the wiring groove 25 can both be used for heat dissipation of the seat body 2 to provide heat dissipation efficiency.

[0057] Exemplarily, two wiring grooves 25 are provided on a side of the seat body 2 facing away from the shell 1 , and the two wiring grooves 25 are symmetrically arranged with respect to the groove 23 to maintain the aesthetics of the acoustic device.

[0058] Please refer to Figure 2 and Figure 7 In one embodiment, a connecting hole 26 is opened on the side of the seat body 2 facing away from the shell 1, and the connecting member 6 is connected to the shell 1 through the connecting hole 26. The acoustic device also includes a foot pad 5, which is connected to the side of the seat body 2 facing away from the shell 1 and covers the connecting hole 26.

[0059] In this embodiment, the connecting member 6 can be a screw, and a fixing hole is provided on the shell 1 corresponding to the connecting hole 26, and the screw passes through the connecting hole 26 and the fixing hole in sequence to connect the seat 2 and the shell 1. Specifically, the connecting holes 26 can be opened on the metal member 21 and the heat insulating member 22, and the metal member 21, the heat insulating member 22 and the shell 1 are connected by the connecting member 6. Of course, the metal member 21 and the shell 1 can also be connected by the connecting member 6, and the heat insulating member 22 is connected to the metal member 21 by another connection method. In order to improve the aesthetics, the connecting hole 26 is covered by the foot pad 5, and the connecting member 6 is covered to avoid the connecting member 6 from being exposed, and the appearance is better. The connection method between the foot pad 5 and the seat 2 can be bonding, clamping, etc., without the need for additional connecting parts. The foot pad 5 can be rubber, plastic, silicone, etc., which can play an anti-slip role.

[0060] In one embodiment, a plurality of connection holes 26 are provided on a side of the seat body 2 facing away from the housing 1, and the acoustic device includes a plurality of foot pads 5, each foot pad 5 being installed in a corresponding connection hole 26. The number of the connection holes 26 can be multiple to improve the connection stability between the seat body 2 and the housing 1, and correspondingly, the number of the foot pads 5 is the same as the number of the connection holes 26.

[0061] like Figure 7As shown, in one embodiment, in order to prevent the foot pad 5 from being displaced, a positioning groove 27 is provided on the side of the seat body 2 facing away from the housing 1, and the connecting hole 26 is provided on the bottom wall of the positioning groove 27, and a part of the foot pad 5 is accommodated and limited in the positioning groove 27. It can be understood that the shape of the positioning groove 27 is adapted to the shape of the foot pad 5, and the positioning groove 27 is used to position and install the foot pad 5. At the same time, the side wall of the positioning groove 27 can limit the translation of the foot pad 5, thereby reducing the risk of the foot pad 5 being loosened.

[0062] Please refer to Figure 4 , Figure 5 and Figure 8 In one embodiment, the periphery of the foot pad 5 is provided with a flange 51, which is limitedly abutted against the seat body 2 and is located outside the positioning groove 27. It can be understood that the outline of the flange 51 is larger than the outline of the notch of the positioning groove 27. After the foot pad 5 is installed in the positioning groove 27, the positioning groove 27 can be covered as a whole to prevent the connector 6 from being exposed and the positioning groove 27 from being visible, thereby improving the aesthetics.
