Description

Technical Field

[0001] This utility model relates to the field of microphone technology, and in particular to a microphone sound reception indicator mechanism and a microphone. Background Technology

[0002] Traditional microphones have a directional sound indication structure. Generally, this indication structure is engraved in a conspicuous position on the microphone housing (top cover, side wall operating surface). When the user is using it, the polarity of the pattern (heart, circle, double heart, etc.) can provide the corresponding microphone direction to facilitate the user's recording work.

[0003] Existing indicator patterns are mostly simply engraved on the microphone shell. These patterns are small and only intended to help users remember the microphone's pickup direction and select the pickup angle upon first use. They lack a clear visual cue. During recording, users' eyes are generally focused on the screen, and after a period of use, they may easily deviate from the optimal pickup angle corresponding to the microphone's direction, requiring readjustment based on the indicator pattern. The small size of the indicator pattern also requires users to expend considerable attention to search and focus, leading to decreased concentration and potentially affecting live streaming quality, gaming experience, and recording continuity. Therefore, this application proposes a microphone pickup indicator mechanism and a microphone. Utility Model Content

[0004] The purpose of this invention is to provide a microphone sound reception indicator mechanism and a microphone to solve the problem that the current microphone indicator structure is not clear enough and is difficult for users to see.

[0009] Furthermore, the multiple indicator lights are spaced apart.

[0010] Furthermore, the radio indication mechanism also includes:

[0011] Multiple light guides are distributed on the outside of the indicator light to scatter the light from the indicator light to the outside of the microphone.

[0012] Furthermore, the radio indication mechanism also includes:

[0013] A ring-shaped circuit board, wherein the microphone core is located in the middle of the ring-shaped circuit board;

[0016] A light-blocking element is connected to the housing of the annular circuit board and / or the light guide and / or the microphone, and the light-blocking element is at least partially located between two adjacent indicator lights to isolate the light of the indicator lights.

[0017] Furthermore, the radio indication mechanism also includes:

[0018] A location acquisition component is used to acquire the location of a sound source, and the control unit is electrically connected to the location acquisition component to receive information from the location acquisition component;

[0019] An alarm component is provided, wherein when the sound source is in a non-receiving area, the control unit controls the alarm component to generate an alarm message.

[0020] Furthermore, the location acquisition component is a distance sensor.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0034] Example 1

[0035] like Figure 1 As shown, an embodiment of the present invention provides a microphone reception indicator mechanism, which includes multiple indicator lights 10 and a control unit. The multiple indicator lights 10 are arranged in a ring on the microphone, and the microphone core 20 of the microphone is located on the axis of the ring structure formed by the multiple indicator lights 10. The control unit is used to control some of the indicator lights 10 to emit light, and the fan-shaped area formed by the emitting indicator lights 10 and the microphone core 20 indicates the reception area of ​​the microphone core 20.

[0036] The microphone's sound reception indicator mechanism disclosed in this embodiment is mounted on the microphone. The control unit can identify the microphone's on / off state. Simultaneously, the control unit and multiple indicator lights 10 are powered by the microphone's power supply. When the microphone is on, the control unit detects the microphone's on state and activates the indicator lights 10 at preset positions. The illuminated indicator lights 10 indicate the microphone core 20's sound reception area. The fan-shaped area formed by the illuminated indicator lights 10 and the microphone core 20 coincides with the area where the microphone core 20 has good sound reception (e.g., ...). Figure 4 As shown), the illuminated indicator lights 10 form an arc, and the lines connecting the indicator lights 10 at both ends of the arc to the microphone core 20 (as shown) Figure 3 The midpoint line indicates the edge of the fan-shaped area. The fan-shaped area enclosed by the two lines is the area where the microphone core 20 has a good sound reception effect. When the user is looking for the microphone's sound reception area, he / she only needs to observe the illuminated indicator light 10. The illuminated indicator light 10 is clearly observable, and the user can easily find the microphone's sound reception area.

[0037] It should be noted that in this embodiment, the indicator light 10 may also have other indication methods. For example, the indicator light 10 may also indicate the sound receiving area by emitting different lights. For example, the light used to indicate the sound receiving area is green, and the light used to indicate the area with poor sound reception is red.

[0038] In this embodiment, the arrangement of the annular structure is based on the shape of the microphone housing. Therefore, the positions of the microphone core 20 and the annular structure can also be in other ways. For example, for some non-cylindrical microphone housings, the axis of the microphone core 20 does not coincide with the axis of the microphone. In this case, the axis of the annular structure does not coincide with the axis of the microphone core 20. In some other embodiments, the sound reception indicator mechanism can also be independent of the microphone. For example, the sound reception indicator mechanism has no physical connection with the microphone and is only electrically connected through a communication link (such as Bluetooth, WiFi, or other wireless connections) to identify the microphone status of the control unit.

[0039] Specifically, in this embodiment, the indicator light 10 is an LED bead, which can be a monochrome LED bead or a multi-color LED bead. The monochrome LED bead can indicate the microphone's sound-receiving area by emitting light, while the multi-color LED bead can indicate the microphone's sound-receiving area by using different colors.

[0040] As a preferred embodiment of this example, Figure 2 and Figure 3 As shown, the multiple indicator lights 10 are distributed at intervals;

[0041] Preferably, the multiple indicator lights 10 are equidistantly distributed on the annular structure. For example, in this embodiment, there are sixteen indicator lights 10, and the angle between each indicator light 10 is 22.5 degrees.

[0042] In this embodiment, the indicator light 10 and the control unit are both soldered onto a ring circuit. When the radio indicator mechanism is installed on the microphone, the ring circuit board 40 is fixed to the microphone housing or top cover with screws. The microphone housing or top cover has a light-transmitting hole at the corresponding position of the indicator light 10, and the light emitted by the indicator light 10 is transmitted through the light-transmitting hole.

[0043] In this embodiment, the control unit is an existing LED lamp bead control chip, such as the SZY48G chip, which controls the output voltage or current by adjusting the pulse width through PWM, thereby controlling the LED lamp to emit light.

[0044] In this embodiment, there are two microphone cores 20, which are mirrored, so that the microphone's sound pickup area is two mirrored areas, which can increase the microphone's sound pickup area. Then, the indicator light 10 will generate light in the sound pickup area of ​​each microphone core 20.

[0045] It should be noted that, in this application, the receiving area is an area with good sound reception performance, such as... Figure 4 and Figure 5 The area enclosed by the midpoint line.

[0046] Example 2

[0047] like Figure 1 As shown, as another embodiment of the present invention, the difference between this embodiment and embodiment 1 is that the radio indicator mechanism further includes a plurality of light guides 30, which are distributed on the outside of the indicator light 10 to scatter the light of the indicator light 10 to the outside of the microphone;

[0048] Specifically, in this embodiment, the light guide 30 is an annular transparent acrylic plate / glass. The outer side of the non-conductive area of ​​the light guide 30 is provided with a frosted structure to scatter light, while the conductive area is provided with a smooth surface, thereby creating a difference in brightness between the conductive and non-conductive areas of the light guide 30. The conductive area on the light guide 30 is located at the corresponding position of the indicator light 10. For example, the light guide 30 made of acrylic plate has a spherical protrusion on the corresponding part of the indicator light 10 on its outer side. The spherical protrusion has a smooth structure, while the remaining part on the outer side has a frosted structure. The inner side of the light guide 30 has a smooth structure, and the light entering the light guide 30 is transmitted to the outside through the spherical protrusion.

[0049] The light guide 30 is fixed to the microphone housing or the ring circuit board 40 by screws or adhesive, and the spherical protrusion is located at the light-transmitting hole;

[0050] In this embodiment, the light guide 30 can also be other structures, such as a light guide column. Each indicator light 10 corresponds to a light guide column, and the light from the indicator light 10 is emitted from the outside of the microphone housing through the light guide column.

[0051] Example 3

[0052] like Figure 1 As shown, as another embodiment of the present invention, the difference between this embodiment and embodiment 2 is that the radio indicator mechanism further includes a light-blocking member 50, which is connected to the annular circuit board 40 and / or the light guide member 30 and / or the microphone housing. The light-blocking member 50 is at least partially located between two adjacent indicator lights 10 to isolate the light of the indicator lights 10.

[0053] In this embodiment, the light-blocking component 50 is an opaque structure, such as black rubber, sponge, or plastic block. The light-blocking component 50 can be mounted on the annular circuit board 40, or it can be mounted on the light guide component 30 and the microphone, such as... Figure 2 As shown, the light-blocking component 50 is mounted on the annular circuit board 40, and the light-blocking component 50 and the annular circuit board 40 can be fixed by screws or bonded with hot melt adhesive.

[0054] The light-blocking component 50 can also be fixed to the light guide component 30. For example, in other embodiments, the light guide component 30 is fixed to the inner side of the light guide component 30 by adhesive. In this case, the light guide component 30 is ring-shaped.

[0055] The light-blocking component 50 can also be fixed to the microphone housing. The light guide component 30 is a light guide post. The light-blocking component 50 is fixed to the inside of the microphone housing by adhesive, such as the inside of the microphone top cover or the support structure inside the microphone used to connect its components.

[0056] The light-blocking component 50 can also be connected to both the light guide component 30 and the annular circuit board 40. For example, the light guide component 30 is a light guide column, and the light-blocking component 50 is an opaque plastic block. The light guide column is fixed to the light-blocking component 50 by adhesive, and the light-blocking component 50 is fixed to the annular circuit board 40 by screws.

[0057] Example 4

[0058] like Figure 1As shown, as another embodiment of the present invention, the difference between this embodiment and embodiment 2 is that the radio indication mechanism further includes a location acquisition component 60 and an alarm component. The location acquisition component 60 is used to acquire the location of the sound source. The control unit is electrically connected to the location acquisition component 60 to receive information from the location acquisition component 60. When the sound source is in a non-receiving area, the control unit controls the alarm component to sound an alarm.

[0059] Specifically, such as Figure 1 and Figure 5 As shown, the location acquisition component 60 and the alarm component are located on the ring circuit board 40. The location acquisition component 60 is electrically connected to the control unit through a conductive strip on the ring circuit. The location acquisition component 60 identifies the location of the sound source. When the sound source is located in a non-receiving area, such as being too far from the microphone, deviating from the microphone's receiving area, or too close to the microphone, the control unit issues an alarm message through the alarm component.

[0060] Specifically, in this embodiment, the location acquisition component 60 can be a distance sensor or an image acquisition device. When the location acquisition component 60 is a distance sensor, the distance sensor can be an acoustic distance sensor, an infrared position sensor, etc. When the user uses the microphone, the user is closest to the microphone, and the distance sensor can detect the distance between the user and the microphone. When the distance between the user and the microphone exceeds a preset value / belows a preset value / the user is not detected, the control unit generates alarm information through the alarm component.

[0061] When the position acquisition component 60 is an image acquisition device, each position acquisition component 60 is equipped with two image acquisition devices, so that the position acquisition component 60 can measure the position through binocular vision. The method of measuring position through binocular vision is existing technology and will not be described in detail here.

[0062] The alarm device can be a light alarm device, such as the control unit generating other colored lights through the indicator light 10 to issue alarm information. The alarm device can also be other structures, such as an information sending device (communication module), through which the control unit sends alarm information to the user's terminal (display screen, controller, etc.).

[0063] In this embodiment, the number of the location acquisition components is the same as that of the microphone core 20, that is, each microphone core 20 corresponds to one location acquisition component 60.

[0064] Example 5

[0065] This utility model also discloses a microphone, which includes a microphone reception indicator mechanism of any one of Embodiment 1, Embodiment 2, Embodiment 3 or Embodiment 4. The microphone reception indicator mechanism is fixed to the inside of the microphone by means of adhesive or screw connection, and the power supply structure of the microphone supplies power to the microphone reception indicator mechanism.

[0066] Preferably, the microphone further includes a housing and a lens connected to each other, and the lens is correspondingly arranged with the position acquisition component 60 of the indicating mechanism. If the position acquisition component 60 is an infrared position sensor or an image acquisition device, the lens is embedded in the housing. The lens is located at the light emitting end and light receiving end of the infrared position sensor, the lens end of the image acquisition device, and other structures of the microphone (such as the microphone core 20, circuit board, etc.) are fixed on the housing.
