[0041] The following will be combined with Figures 1-7 to describe the electronic device of the present invention.

[0042] Such as Figures 1 to 3As shown in the figure, an electronic device includes a first housing 10 and a second housing 11 that are connected to each other. The first housing 10 and the second housing 11 can cooperate with each other to form a receiving cavity 12. The first housing 10 and the second housing 11 can both be in the shape of a box, and the two are buckled to form a relatively enclosed receiving cavity 12, providing space for the installation of electronic components such as the main circuit board 20 and the speaker 40. Alternatively, the first housing 10 is in the shape of a cover, and the second housing 11 is in the shape of a box. The first housing 10 covers the second housing 11 to form a relative receiving cavity 12. Among them, the electronic device is an omnidirectional microphone, a smart phone, a tablet computer, or other devices with playback and sound pickup functions.

[0043] As Figure 2 shown in the figure, the main circuit board 20 is installed in the receiving cavity 12. The main circuit board 20 is the control circuit board of the electronic device and is fixed in the receiving cavity 12 by fasteners such as screws. The main circuit board 20 has data processing and arithmetic units and can process audio information.

[0044] The counterweight 30 is arranged in the receiving cavity 12 and is connected to the main circuit board 20. Optionally, the counterweight 30 is a battery. For example, the counterweight 30 is a lithium-ion battery, a nickel-cadmium storage battery, or a nickel-metal hydride storage battery. The battery is connected to the main circuit board 20 to supply power to the main circuit board 20. The two speakers 40 are respectively arranged on opposite sides of the counterweight 30. By means of the counterweight 30, the two speakers 40 are separated to prevent interference between the two speakers 40 when playing audio. The two speakers 40 are respectively connected to the main circuit board 20, and communicate with the speakers 40 through the main circuit board 20 to control the speakers 40 to play audio information.

[0045] The speaker 40 is arranged in the receiving cavity 12 by connecting to the first housing 10. Taking an omnidirectional microphone as an example, it has the functions of playing audio and picking up audio. When the pickup 50 and the speaker 40 are working, they both rely on the vibration of the diaphragm, and the vibrations of the two are likely to interfere with each other and generate noise. For example, the sound waves generated by the speaker 40 when playing audio propagate in the air and may be reflected into the pickup 50, generating echo noise. Therefore, a first sound insulation cover 41 is provided to block the sound waves generated by the speaker 40 when driving backward.

[0046] As Figure 3As shown, the first soundproof cover 41 is fixed to the first shell 10 and corresponds to the speaker 40, and the speaker 40 can be set in a relatively independent first soundproof cavity 42. It can be understood that the first shell 10 is provided with a through hole for sound output corresponding to the speaker 40. The first shell 10 is directly fixedly connected to the first soundproof cover 41, and the first soundproof cover 41 has a recess, which is sealed with the first shell 10 by means of glue sealing or sealing ring. The recess is sealed by the first shell 10 to form a closed first soundproof cavity 42, blocking the echo of the rear sound cavity of the speaker 40 from propagating outward, avoiding interference with the operation of other electronic devices. Alternatively, the first soundproof cover 41 is indirectly connected to the first shell 10. For example, the speaker 40 has a mounting seat, and the first soundproof cover 41 is fixedly connected to the mounting seat to form the first soundproof cavity 42.

[0047] Optionally, the first sound insulation cover 41 is a plastic part. To improve the sound insulation effect, sound insulation foam is laid inside the first sound insulation cover 41.

[0048] like Figure 4 As shown, the electronic device further includes a microphone 50 and a second soundproof cover 51. The microphone 50 is connected to the main circuit board 20 and is arranged in the accommodating cavity 12 by being connected to the second shell 11. The second soundproof cover 51 is arranged corresponding to the microphone 50, and is used to arrange the microphone 50 in a relatively closed second soundproof cavity 52.

[0049] The microphone 50 is a functional device for acquiring external audio information, which communicates with the main circuit board 20 through a wire and transmits the acquired external audio information to the main circuit board 20 for processing and analysis. The second housing 11 is provided with a sound pickup through hole 13 corresponding to the microphone 50 .

[0050] The speaker 40 is equivalent to a vibration source when making a sound, and the mechanical vibration generated will be transmitted to the microphone 50 through the structural parts, generating noise. The speaker 40 is installed in the first shell 10, and the microphone 50 is installed in the second shell 11, so that the mechanical transmission path between the speaker 40 and the microphone 50 is increased. Compared with the method of installing both in the same shell, the interference between the microphone and the speaker 40 can be effectively reduced. In addition, in order to prevent the broadcast vibration of the speaker 40 from affecting the sound pickup effect, the traditional method is to ensure that there is a safe distance between the microphone 50 and the speaker 40. In the electronic device provided in the embodiment of the present invention, the distance between the microphone 50 and the speaker 40 can be minimized, making the internal space of the whole machine more compact, which helps to achieve the miniaturization of the whole machine.

[0051] Optionally, the second sound insulation cover 51 is made of rubber or silica gel. The second sound insulation cover 51 is provided corresponding to the pickup 50, and the pickup 50 is housed in the relatively enclosed second sound insulation cover 51. For example, the second sound insulation cover 51 has a groove body, with an edge provided at the notch of the groove body, and double-sided tape is pasted on the edge. It is directly bonded and fixed to the second housing 11 by means of the double-sided tape, and the notch of the groove body is closed by the second housing 11 to form a closed second sound insulation cavity 52. Another example is that the second sound insulation cover 51 can be directly fixed on the pickup circuit board 53 of the pickup 50 to achieve indirect connection with the second housing 11, which can also play a sound insulation role.

[0052] As Figure 2 shown, there are multiple pickups 50, and a second sound insulation cover 51 is provided corresponding to each pickup 50. The multiple pickups 50 are separately arranged on two opposite side walls of the second housing 11. Four pickups 50 are installed on each side wall.

[0053] When the speaker 40 emits sound, vibration waves will be generated. When the vibration waves are transmitted to the pickup 50, it will cause the pickup 50 to generate noise. By installing the pickup 50 in the second sound insulation cavity 52, the second sound insulation cavity 52, as a closed space, can further block the influence of the echo of the speaker 40 on the pickup 50.

[0054] In a specific embodiment, as Figure 4 shown, the pickup 50 includes a pickup head 54, a pickup circuit board 53 and a pressing plate 55. The pickup circuit board 53 is fixed to the second housing 11 and is electrically connected to the main circuit board 20. The second sound insulation cover 51 is fixed to the pickup circuit board 53 to form the second sound insulation cavity 52. The pickup head 54 is installed on the pickup circuit board 53 and is located in the second sound insulation cavity 52. The pressing plate 55 is fixed to the second housing 11 and presses on the second sound insulation cover 51.

[0055] The pickup circuit board 53 is fixed to the second housing 11 by colloid or screws. The second sound insulation cover 51 is adhesively fixed to the side of the pickup circuit board 53 away from the second housing 11 by means of double-sided tape, so that the groove body is closed by the pickup circuit board 53 to form the second sound insulation cavity 52, blocking the influence of the echo of the speaker 40.

[0056] The pressing plate 55 is provided with a through hole, and the groove body main body of the second sound insulation cover 51 passes through the through hole. The shape and size of the through hole are the same as those of the groove body in the second sound insulation cover 51. For example, the groove body is hemispherical, and correspondingly, the pressing hole is circular to ensure that the hole wall of the pressing hole fits the outer wall of the groove body. Or, the groove body is square, and correspondingly, the pressing hole is a square hole. The pressing plate 55 is fastened to the second housing 11 by screws, so that the edge at the notch of the groove body is pressed on the pickup circuit board 53 by means of the pressing plate 55, improving the installation stability of the second sound insulation cover 51. Optionally, the pressing plate 55 is a flat plate or an L-shaped plate.

[0057] To reduce the mechanical vibration between the pickup 50 and the second housing 11, a first buffer member 61 is interposed between the inner wall of the second housing 11 and the pickup circuit board 53.

[0058] Optionally, the first buffer member 61 is a foam, and the opposite sides of the foam are respectively bonded and fixed to the second housing 11 and the circuit board through adhesive. When the speaker 40 plays audio, the vibration generated is transmitted along the first housing 10 to the second housing 11, and the vibration transmitted to the pickup circuit board 53 is reduced by means of the first buffer member 61.

[0059] As Figure 2 and Figure 3 shown, the pickup 50 is installed on the side wall of the second housing 11, the speaker 40 is installed in the first housing 10, and the axis of the sound outlet hole of the speaker 40 and the axis of the pickup hole of the pickup 50 form an angle.

[0060] For example, the pickup 50 is installed on the side wall of the second housing 11, and this side wall is perpendicular to the side of the first housing 10 where the speaker 40 is installed. The axes of both the pickup hole and the sound outlet hole are perpendicular to the wall surface where they are located, so that the axis of the sound outlet hole and the axis of the pickup hole form a 90° angle. Another example is that the axes of both the sound outlet hole and the pickup hole are inclined to the wall surface where they are located, so that the angle formed by the axis of the sound outlet hole and the axis of the pickup hole is greater than 90° or less than 90°.

[0061] Preferably, the angle formed by the axis of the pickup hole and the axis of the sound outlet hole is not less than 90°. The angle between the pickup direction of the pickup 50 and the sound outlet direction of the speaker 40 is not less than 90°, so as to prevent the sound wave in the front sound cavity of the speaker 40 from directly being transmitted to the pickup hole to interfere with the pickup of the pickup 50. As Figure 2 shown, eight pickups 50 are evenly distributed on the two side edges of the second housing 11 along the length direction, and two speakers 40 are fixed to the first housing 10 and are respectively arranged on the opposite sides of the counterweight 30, effectively preventing the sound wave echo in the front sound cavity of the speaker 40 from directly entering the pickup holes of the pickups 50 and interfering with the pickup of the pickups 50.

[0062] In the electronic device provided by the present invention, the speaker 40 is arranged in the first sound insulation cavity 42, and the pickup 50 is arranged in the second sound insulation cover 51, blocking the echo in the rear sound cavity generated by the speaker 40 and being able to weaken the marketing of the pickup 50. At the same time, the sound emission direction of the speaker 40 and the pickup direction of the pickup 50 form a certain angle, which can effectively suppress the echo in the front sound cavity of the speaker 40 and prevent it from directly entering the pickup 50.

[0063] As Figure 5 and Figure 6 shown, a groove 14 is provided on the side of the second housing 11 relatively far from the speaker 40. A power supply interface and an input network interface are respectively provided on two adjacent side walls of the groove 14, and this input network interface can also be powered through the connected cable.

[0064] When one of the power supply interface and the input network interface is connected to its corresponding connector, since the connector used is a standard part with a certain standard length, the distance between the two interfaces along the length direction of the connector is less than the standard length of the connector. Thus, when one connector is connected, it can prevent the connection of the other interface to another connector, preventing the user from connecting two charging connectors to the device simultaneously and avoiding device damage.

[0065] The power supply interface is electrically connected to the power supply and can charge the power supply. For example, the power supply interface is a DC power supply interface. For instance, the power supply interface is used to connect to a DC power supply with a supply voltage of 48V. The input network interface is connected to the main circuit board 20 and can be in the form of a USB interface, an RJ-45 network interface, etc., and can both transmit audio information and supply power.

[0066] The outer wall of the second housing 11 is provided with a square groove 14. An input network interface is provided on one groove wall in the groove 14, and a power supply interface is provided on another groove wall adjacent to this groove wall, such that the power supply interface and the input network interface are arranged at a right angle within the groove 14. Since there will be interference when connecting the connectors for both, only one of the interfaces can be in a connected state, ensuring that the two external power supply methods cannot be used simultaneously, playing a role in protecting the internal circuit structure and improving the safety of use. As Figure 5 shown, when the power cord 100 is connected to the power supply interface, the cable 110 cannot be connected to the input network interface due to structural interference. Only after the power cord 100 is removed, as Figure 6 shown, can the cable 110 be connected to the input network interface.

[0067] In addition, an output network interface (not shown in the figure) is also installed in the groove 14. The output network interface is used for cascading with external devices. The output network interface and the input network interface are respectively located on opposite groove walls of the groove 14.

[0068] The output network interface is electrically connected to the main circuit board 20 and can transmit information such as audio to external devices. For example, the input network interface is located on the left groove wall of the groove 14, and the output network interface is located on the right groove wall, and the input network interface and the output network interface are arranged in a staggered manner.

[0069] As Figure 3 shown, the electronic device further includes a third housing 15. The third housing 15 is separately provided from the first housing 10, and the two are adhesively fixed through a foam adhesive 70.

[0070] A mesh cloth 17 is fixed to the side of the third housing 15 away from the second housing 11. The mesh cloth 17 can achieve a decorative effect, making the appearance of the whole machine more beautiful, and can also block external dust from entering the speaker 40, playing a role in protecting the speaker 40.

[0071] As Figure 3 shown, a sound outlet through hole 16 is provided on the third housing 15. To avoid resonance of the third housing 15 caused by the vibration of the speaker 40, a foam adhesive 70 with a certain thickness is provided between the first housing 10 and the third housing 15. While connecting the third housing 15 and the first housing 10, the foam adhesive 70 can also relieve the vibration of the third housing 15.

[0072] In addition, the first housing 10 and the third housing 15 can also be locked and fixed by connecting parts such as screws. To avoid resonance between the third housing 15 and the speaker 40, a buffer structure made of foam or silica gel can be provided between the first housing 10 and the third housing 15.

[0073] To avoid the mechanical vibration generated by the speaker 40 from being transmitted to the first housing 10, a second buffer member 62 is provided between the speaker 40 and the first housing 10. The second buffer member 62 and the first buffer member 61 can be made of the same material or different materials. Optionally, the second buffer member 62 is a foam or a rubber gasket 64 ring. For example, when the second buffer member 62 is a foam, by means of the acting force of the speaker 40 being attached to the first housing 10, the foam is pressed tightly, so as to relieve the mechanical vibration transmission from the speaker 40 to the first housing 10 by means of the foam.

[0074] As Figure 7 shown, a third buffer member 63 is provided between the first housing 10 and the second housing 11. The third buffer member 63 is clamped between the contact surfaces of the first housing 10 and the second housing 11. After the first housing 10 is fixed to the second housing 11, the third buffer member 63 is pressed tightly. By means of the third buffer member 63, the mechanical vibration transmission between the first housing 10 and the second housing is buffered. For example, the third buffer member 63 includes a rubber gasket 64 and a screw rubber gasket 65. The rubber gasket 64 is clamped between the first housing 10 and the second housing 11, and the screw rubber gasket 65 is arranged on the stud of the second housing 11. When the first housing 10 and the second housing 11 are locked by screws, the rubber gasket 64 and the screw rubber gasket 65 are pressed tightly, effectively buffering the mechanical vibration from the first housing 10 to the second housing 11, relieving the mechanical vibration transmitted from the speaker 40 to the pickup 50, and reducing the interference of the speaker 40 on the pickup 50. Among them, the rubber gasket 64 can be injection-molded on the first housing 10 through a secondary injection molding process and is integrally structured with the first housing 10, which can also play a role in vibration reduction.

[0075] For the electronic device provided by the present invention, a second buffer member 62 is provided between the speaker 40 and the first housing 10, a third buffer member 63 is provided between the first housing 10 and the second housing 11, a first buffer member 61 is provided between the second housing 11 and the sound pickup circuit board 53, and the sound pickup head 54 is welded and fixed to the sound pickup circuit board 53. Thus, multiple buffer members are provided on the transmission path of the mechanical vibration of the speaker 40 to reduce the interference of the speaker 40 on the sound pickup device 50.

[0076] As Figure 4 shown, the second housing 11 is provided with air feet 80, and the air feet 80 have air grooves 81 communicating with the external atmosphere.

[0077] Optionally, the air feet 80 are rubber pads 64, and air grooves 81 communicating with the atmosphere are provided in the middle. When the air feet 80 are fixed on the outer side of the bottom wall of the second housing 11, the air grooves 81 communicate with the external atmosphere through the connection gap between the air feet 80 and the second housing 11. When the entire electronic device vibrates, the air in the air grooves 81 is compressed and slowly released, thereby buffering a part of the mechanical vibration energy and playing a role in alleviating vibration.

[0078] Specifically, four air feet 80 are installed on the second housing 11, and the four air feet 80 are arranged in a square shape, providing stable support for the entire electronic device and capable of buffering external vibrations.

[0079] As Figure 1 shown, the electronic device further includes a power button 91, a function button 92, and an indicator light 93. The power button 91 is provided on the side wall of the second housing 11 and is located on the side wall of the whole machine. The power button 91 is used to turn on or off the electronic device when triggered. The function button 92 is installed on the first housing 10 and is located at the top of the whole machine. There are multiple function buttons 92, which are used to execute corresponding functions when triggered. For example, the function buttons 92 include a mute button, a volume adjustment button, a standby button, etc. The indicator light 93 is located beside the function button 92. The indicator light 93 is used to indicate the current working state of the electronic device. For example, after the electronic device is turned on, the indicator light 93 is in a green constant-on state or a low-battery yellow constant-on state; in the recording state, the indicator light 93 is in a flashing state; in the mute state, the indicator light 93 is in a red state, and only the sound can be played through the speaker 40, and the sound cannot be recorded through the sound pickup device 50.

[0080] In an embodiment, a strip-shaped LED light strip is further provided on the visible surface of the electronic device. After the power button of the device is long-pressed, the device will start to avoid accidental touch of the user to turn on the device; after the device starts, the current volume size of the device can be identified by the proportion of the lit length of the light strip on it; when muted, the light strip is constantly lit red.

[0081] In one embodiment, when the device is started, the device can be switched to the mode of displaying the battery level through the light strip by pressing the power button for a short time, that is, the remaining battery level is indicated by the proportion of the length of the lit part of the light strip in the whole light strip. In this mode, during the use of the product, if the battery level is lower than 20%, the light strip will flash red to indicate that the battery level is too low. Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
