Background

Microphones are widely used in various sound transmission scenes as electronic devices capable of converting sound signals into electrical signals. In practical application, when the microphone is used in a windy environment, wind noise is generated when wind blows on the microphone, and the sound transmission effect of the microphone is reduced. In windy environment, in order to eliminate or reduce wind noise, a wind-proof part is usually installed outside the microphone to prevent wind from directly blowing on the microphone to generate wind noise, so as to achieve the effect of physical noise reduction; or the noise reduction mode is arranged on the microphone, and the noise reduction mode can be started in a windy environment, so that the audio frequency of the microphone is adjusted, and the influence of wind noise is reduced. The two methods for reducing the wind noise influence can be used in combination.

Detailed Description

In order to make the aforementioned objects, features and advantages of the present application more comprehensible, the present application is described in further detail with reference to the accompanying drawings and the detailed description.

Fig. 1 to 3 are schematic views showing an overall structure of a sound transmission assembly according to an embodiment of the present application, and fig. 4 and 5 are schematic views showing a separate structure of a sound transmission assembly according to an embodiment of the present application. The sound transmission assembly may specifically include: a microphone 10 and a wind shield 11; wherein,

the wind shield 11 is detachably mounted to the microphone 10.

Referring to fig. 6 to 9, schematic structural views of a wind prevention member according to an embodiment of the present application are shown, and referring to fig. 10 to 14, schematic structural views of a microphone according to an embodiment of the present application are shown.

In the embodiment of the present application, the wind-proof member 11 may include a supporting frame 112 and a triggering member 111 disposed on the supporting frame, the sensing member 101 is disposed on the microphone 10, and the triggering member 111 may be configured to cooperate with the sensing member 101, so that the sensing member 101 generates a sensing signal indicating whether the wind-proof member 11 is mounted on the microphone 10.

Specifically, when the microphone 10 is used in a windy environment, the wind-proof member 11 may be mounted on the microphone 10, so as to prevent wind from directly blowing on the microphone 10 to generate wind noise, thereby achieving a physical noise reduction effect, eliminating or reducing the wind noise, and improving the sound transmission effect of the microphone 10.

The wind-proof member 11 exemplarily includes but is not limited to any one of a wind-proof sleeve and a wind-proof retainer ring, the embodiment of the present application is described by taking the wind-proof member 11 as the wind-proof sleeve, and other types of wind-proof members can be implemented by reference. The microphone 10 may include, but is not limited to, at least one of a wired microphone and a wireless microphone, and the embodiment of the present application is described only by taking the microphone 10 as a wireless microphone, and other types of microphones may be implemented by reference.

In the embodiment of the present application, since the wind-proof piece 11 is provided with the trigger 111, when the wind-proof piece 11 is mounted on the microphone 10, the sensing piece 101 on the microphone 10 can sense the trigger 111 on the wind-proof piece 11, so as to generate a sensing signal for indicating whether the wind-proof piece 11 is mounted on the microphone 10, and automatically identify whether the wind-proof piece 11 is mounted on the microphone 10, so as to determine whether the noise reduction mode needs to be turned on or off by automatically identifying whether the wind-proof piece 11 is mounted, thereby improving the sound transmission effect of the microphone 10. Moreover, the user can be prevented from judging whether the wind-proof piece 11 is mounted on the microphone 10 by naked eyes or manually, and the efficiency of the user operating the microphone 10 is improved.

In some optional embodiments of the present application, in a case where the wind-proof element 11 is installed on the microphone 10, the sensing element 101 can sense the triggering element 111 to generate an in-place sensing signal, and the in-place sensing signal can trigger the microphone 10 to turn on the noise reduction mode; in the case where the wind shield 11 is not mounted to the microphone 10, the sensing element 101 does not sense the triggering element 111 and generates an out-of-position sensing signal that can trigger the microphone 10 to turn off the noise reduction mode.

Specifically, the execution program of the noise reduction mode may be stored in the memory of the microphone 10 in advance, and when the microphone 10 is used in a windy environment, the noise reduction mode may be turned on, and the audio frequency of the microphone 10 may be adjusted to reduce the influence of wind noise and improve the sound transmission effect of the microphone 10. Illustratively, adjusting the audio of microphone 10 may include reducing low frequency portions of the audio. The noise reduction mode needs to be turned off when the microphone 10 is switched to use in a calm environment to avoid distortion of the sound of the microphone 10.

In practice, when the user mounts the wind shield 11 for the microphone 10, it means that there is wind in the environment. Once the wind-proof element 11 is mounted on the microphone 10, the sensing element 101 senses the trigger element 111 to generate an in-place sensing signal, which can trigger the microphone 10 to automatically turn on the noise reduction mode, so that the noise of the microphone 10 is reduced or eliminated by using the noise reduction mode and the wind-proof element 11 together, and the sound transmission effect of the microphone 10 is improved. In the embodiment of the application, the noise reduction mode of the microphone 10 can be automatically started through the in-place recognition of the windproof part 11, the opening timeliness and convenience of the noise reduction mode can be greatly improved, and a good sound transmission effect is guaranteed.

In particular, when the user removes the wind shield 11 from the microphone 10, it means that there is no wind in the environment. Once the wind shield 11 is removed from the microphone 10, the sensing element 101 may generate an out-of-position sensing signal due to the absence of sensing the triggering element 111, and the out-of-position sensing signal may trigger the microphone 10 to automatically turn off the noise reduction mode to prevent sound distortion of the microphone 10. In the embodiment of the application, the noise reduction mode of the microphone 10 can be automatically closed through the non-in-place recognition of the windproof piece 11, so that the timeliness and convenience of closing the noise reduction mode are greatly improved.

In the embodiment of the application, whether the noise reduction mode of the microphone 10 needs to be turned on or turned off is judged by automatically identifying whether the windproof piece 11 is installed, so that the sound transmission effect of the microphone 10 can be improved, the operation that a user manually turns on or turns off the noise reduction mode is avoided, and the efficiency of operating the microphone 10 by the user is improved.

In the embodiment of the present application, the number of the wind-proof pieces 11 is multiple, wherein the sensing signals triggered by different wind-proof pieces 11 are different in the multiple wind-proof pieces 11.

Specifically, in order to adapt to different air volume level environments, different windshields 11 may be provided. Different wind-proof pieces 11 have different wind noise reducing capabilities, and the corresponding noise reduction modes are correspondingly different. Since the sensing signals triggered by different wind-proof pieces 11 are different, the type of the wind-proof piece 11 can be determined by identifying the sensing signal excited by the wind-proof piece 11, and according to the type of the wind-proof piece 11, a corresponding noise reduction mode can be triggered to further improve the sound transmission effect of the microphone 10.

In the embodiment of the present application, the windproof component 11 may include: the wind-proof part 11 can be detachably mounted on the microphone 10 through the supporting framework 112, the supporting framework 112 is provided with a position-avoiding hole 113, the position-avoiding hole 113 is opposite to the sound inlet 102 of the microphone 10 and is used for allowing sound to enter the sound inlet 102, and the trigger part 111 is arranged on the supporting framework 112; and a noise reduction part 114, wherein the noise reduction part 114 is connected to the support framework 112 and is used for reducing wind noise.

In practical applications, the supporting frame 112 may be used as a supporting body of the wind-proof member 11 and detachably mounted on the microphone 10. The supporting frame 112 may be made of metal, plastic, or other materials with certain strength, and the specific material of the supporting frame 112 in the embodiment of the present application may not be limited. The noise reduction unit 114 may be used to reduce wind noise, and may be made of a material having a noise reduction function, such as sponge or silk.

Optionally, the noise reduction portion 114 may include, but is not limited to, at least one of a sponge member and wind-proof hair, and the specific type of the noise reduction portion 114 may not be limited in the embodiments of the present application.

In the embodiment of the present application, when the wind-proof component 11 is mounted on the microphone 10, the supporting frame 112 may be sandwiched between the microphone 10 and the noise reduction portion 114, so that external sound may firstly pass through the noise reduction portion 114 to reduce wind noise, and then sequentially pass through the avoiding hole 113 on the supporting frame 112 and the sound inlet hole 102 on the microphone 10 to enter the interior of the microphone 10, so as to further improve the wind noise reduction effect of the wind-proof component 11.

In some alternative embodiments of the present application, the triggering member 111 may be a magnetic member, and the microphone 10 is provided with a ferromagnetic member 103 capable of being attracted by the magnetic member, so that the wind-proof member 11 can be attracted and fixed to the microphone 10 by the magnetic member, so that the wind-proof member 11 can be detachably mounted to the microphone 10.

In practical applications, in the case that the triggering element 111 is a magnetic element, on one hand, the sensing element 101 on the microphone 10 can be triggered to generate a sensing signal, and on the other hand, the sensing element can be attracted by the ferromagnetic element 103 on the microphone 10, so that the windproof element 11 can be detachably connected to the microphone 10, thereby avoiding an additional connecting element on the windproof element 11 to achieve the detachable connection between the windproof element 11 and the microphone 10, reducing the number of parts in the windproof element 11, and simplifying the structure of the windproof element 11.

It should be noted that, in practical applications, the magnetic component on the windproof component 11 may also be used only to realize the detachable connection between the windproof component 11 and the microphone 10, and the triggering component 111 may also adopt other types of triggering components such as a conductive component, a force-transmitting component, and the like, which is not limited in this embodiment of the present application.

In the embodiment of the present application, the ferromagnetic piece 103 may be a housing of the microphone 10, which is at least partially made of a ferromagnetic material; alternatively, the ferromagnetic member 103 is a ferromagnetic plate disposed on the microphone 10, and the embodiment of the present application is not limited to the specific form of the ferromagnetic member 103.

Specifically, the ferromagnetic member 103 may be made of ferromagnetic material capable of being magnetically adsorbed, such as iron, steel, nickel, cobalt, and the like, and the specific material of the ferromagnetic member 103 may not be limited in this embodiment.

In the embodiment of the present application, the magnetic member on the windproof member 11 is an annular magnetic member, and the annular magnetic member is provided with a through hole, and the through hole is communicated with and opposite to the avoiding hole 113, so that sound can enter the sound inlet 102 of the microphone 10 through the through hole and the avoiding hole 113 in sequence.

In practical application, the magnetic member is arranged as an annular magnetic member, and the through hole of the annular magnetic member is opposite to the avoiding hole 113, so that the positioning of the magnetic member on the windproof member 11 is facilitated, the radiation area of the magnetic member is larger, and the reliability of triggering the sensing member 101 by the magnetic member is increased.

It should be noted that, in practical applications, the magnetic member may also be composed of one or more magnetic blocks, and the position of the magnetic block may also be set at any position such as the middle and the edge of the support frame 112 according to needs.

In the embodiment of the present application, the supporting framework 112 is further provided with a positioning element 115 facing away from the noise reduction part 114, and the positioning element 115 can be used to define the installation position of the wind-proof element 11 on the microphone 10; the microphone 10 is correspondingly provided with a positioning groove 104, and in the case that the wind-proof member 11 is mounted on the microphone 10, the positioning member 115 can be embedded in the positioning groove 104 to realize the positioning of the wind-proof member 11 on the microphone 10.

By way of example, the positioning elements 115 may be convex positioning blocks, positioning rods, and the like, the number of the positioning elements 115 may be 2, 3, or 5, and the like, and the specific structure and the specific number of the positioning elements 115 may not be limited in the embodiments of the present application.

In the embodiment of the present application, a clamping member may be further disposed on the supporting frame 112, and the clamping member may be used to clamp the wind-proof member 11 to the microphone 10, so as to further increase the connection reliability of the wind-proof member 11 on the microphone 10.

Specifically, the clip may include, but is not limited to, a hook, a buckle, a slot, and the like, and the specific form of the clip may not be limited in the embodiment of the present application.

It should be noted that, in practical applications, a person skilled in the art may select at least one of a magnetic attraction connection and a snap connection according to actual needs to implement the detachable connection between the wind-proof piece 11 and the microphone 10, and the connection manner between the wind-proof piece 11 and the microphone 10 in the embodiment of the present application may not be specifically limited.

In this embodiment of the application, the windproof component 11 may further include: and the support part 116 is arranged between the support framework 112 and the noise reduction part 114, and is used for connecting the support framework 112 and the noise reduction part 114, maintaining the shape of the noise reduction part 114, and preventing the noise reduction part 114 from collapsing and deforming to influence normal use.

Specifically, the hardness of the support portion 116 may be interposed between the support skeleton 112 and the noise reduction portion 114 to increase the connection reliability of the noise reduction portion 114 on the support skeleton 112.

Optionally, the supporting portion 116 and the noise reducing portion 112 may both be made of sponge, and the density of the sponge used by the supporting portion 116 is greater than that of the sponge used by the noise reducing portion 112, so that on one hand, the hardness of the supporting portion 116 can be greater than that of the noise reducing portion to realize reliable support of the supporting portion 116 on the noise reducing portion 112, and on the other hand, the supporting portion 116 can further play a role in reducing wind noise, thereby improving the wind noise reducing effect of the wind-proof part 11.

In some optional embodiments of the present application, the triggering element 111 may be a magnetic element, the sensing element 101 is a hall sensor, and the sensing signal is generated by the hall sensor according to whether a magnetic field of the magnetic element is sensed; the first magnetic pole of the magnetic part is close to the Hall sensor, the second magnetic pole of the magnetic part is far away from the Hall sensor, and the polarity of the second magnetic pole is opposite to that of the first magnetic pole. Therefore, the Hall sensor can quickly generate corresponding sensing signals under the condition of sensing the magnetic field of the magnetic part or not sensing the magnetic field of the magnetic part, and the operation is convenient and quick.

In the embodiment of the present application, the number of the windproof components 11 is plural, wherein at least one of the position of the magnetic component, the magnetic field strength of the magnetic component, and the polarity of the first magnetic pole is different for different windproof components 11 in the plurality of windproof components 11, so that when different windproof components 11 are installed on the microphone 10, the magnetic field sensed by the hall sensor is different, and the sensing signal generated by the hall sensor is correspondingly different. In this way, the noise reduction mode corresponding to the wind shield 11 can be started by detecting the sensing signal generated by the hall sensor, and the sound transmission effect of the microphone 10 is further improved.

Specifically, the first magnetic pole may be an S pole, and the second magnetic pole may be an N pole, or the first magnetic pole may be an N pole, and the second magnetic pole may be an S pole, and the specific contents of the first magnetic pole and the second magnetic pole may not be limited in this embodiment of the application. The magnetic member may be located at an edge region, a middle region, or any position between the edge region and the middle region of the windshield 11. The magnetic field intensity of the magnetic part can be set according to actual conditions, and a Hall sensor on the microphone 10 can be triggered.

In some alternative embodiments, the triggering element 111 may be a touch triggering element, and the sensing element 101 may be a touch sensing element; alternatively, the triggering member 111 may be a non-contact triggering member, and the sensing member 101 may be a non-contact sensing member.

In this embodiment, under the condition that the triggering member 111 is a contact triggering member, the sensing member 101 is a contact sensing member, so that the sensing member 101 can rapidly sense the triggering member 111 and generate a sensing signal through the mutual contact between the triggering member 111 and the sensing member 101, thereby improving the sensitivity of the sensing signal generated by the sensing member 101. Specifically, the contact type triggering component may be a conductive component, and the contact type sensing component may be a current detection circuit. Since the current detection circuit can be used to detect the current change of the conductive member, the sensing member 101 can sense the trigger member 111 by the induced current change and generate a sensing signal. Specifically, the conductive member may be used as a conductor to conduct connection between the sensing member and a power source, or to conduct connection between the sensing member and a controller, or the like.

Specifically, for different windshields 11, the number of contacts, the positions and the resistance of different conductive members may be set, or a circuit board may be set in the windshields 11, and after power is supplied, the circuit board sends the ID or the type corresponding to the windshields 11 to the microphone 10, so as to distinguish the different windshields 11. That is, since the number of contacts, positions, and resistances of the conductive members corresponding to different wind prevention members 11 are different, the different wind prevention members 11 can be distinguished by identifying the different numbers of contacts, positions, and resistances. Alternatively, a circuit board including an ID transmitting device is provided in the windbreak 11. Different windbreak 11 is set with different IDs, and by receiving the ID transmitted by the ID transmitting device set in the windbreak 11, the different windbreak 11 are distinguished.

Alternatively, the touch trigger may be a force transmission member, and the touch sensing member may be a pressure sensor. Since the pressure sensor can be used to detect the pressure change of the force transmission member, the sensing member 101 can sense the trigger member 111 and generate a sensing signal by sensing the pressure change. In particular, the force-transmitting element serves as a force-transmitting intermediate element for transmitting an external force exerted on the triggering element 111 to the sensitive element.

In particular, the force-transmitting member may be a projection. In some embodiments, the protrusion structure may contract when contacted with the sensing member by a pressure applied by the sensing member, thereby applying a pressure to the sensing member in an opposite direction. For example, the protruding structure may be composed of an elastic member and an abutting portion, and the protruding structure can apply pressure to the pressure sensor after the wind-proof member 11 is mounted on the microphone 10. Or, the protruding structure cannot be stretched, and the microphone 10 is provided with a structure which retracts towards the inside of the microphone 10 after being pressed, and the structure can transmit the pressure to the pressure sensor. In practical applications, the protruding structure may be provided on the microphone 10, or other structural designs may be adopted to realize the transmission of the pressure, which is not specifically limited in the present application.

Or, under the condition that the triggering part 111 is a non-contact triggering part, the sensing part 101 may also be a non-contact sensing part, so that under the condition that the triggering part 111 and the sensing part 101 are not in contact, the sensing part 101 can also rapidly sense the triggering part 111 to generate a sensing signal, and the sensing part 101 can generate the sensing signal without contacting the triggering part 111, thereby preventing the sensing part 101 from being exposed to the microphone 10, facilitating the dustproof and waterproof design of the microphone 10, and enabling the microphone 10 to be used in more scenes, such as rainy days or environments with large dust and sand. The non-contact type triggering part is a magnetic part, and the non-contact type sensing part is a Hall sensor. Since the hall sensor can sense the magnetic field change caused by the magnetic member, the sensing member 101 can sense the trigger member 111 and generate a sensing signal by sensing the magnetic field change. Specifically, the magnetic member is a magnet having magnetic induction.

Optionally, the non-contact triggering component may be an infrared transmitter, and the non-contact sensing component may be an infrared receiver. Since the infrared receiver can receive the signal of the infrared transmitter, the sensing element 101 can sense the triggering element 111 and generate a sensing signal through the sensing signal change. In particular, the infrared emitter is used for emitting an infrared light signal or an infrared heat signal.

Optionally, the non-contact sensor may be a capacitive sensor, and the non-contact trigger may be a first electrode plate of the capacitive sensor. Since the capacitance sensor can sense the change of the electrical signal caused by the first electrode plate, the sensing element 101 can sense the trigger element 111 by sensing the change of the electrical signal and generate a sensing signal.

Specifically, the capacitive sensor may be generally composed of two parallel electrodes with air as a medium between the two electrodes, and its capacitance may be expressed as C ═ S/d without considering the edge effect, where ∈ represents the dielectric constant of the medium (i.e., air) between the two electrodes, S represents the area covered by the two electrodes, and d represents the distance between the two electrodes, and the capacitance is affected by these three parameters, and a change in any one parameter will change the capacitance. The identification of the microphone 10 for different windshields can be achieved by varying these three parameters so that a corresponding noise reduction mode is assumed.

The capacitance sensor may be any one of a dielectric change type (e changes and therefore C changes), an area change type (S changes and therefore C changes), and a pole pitch change type (d changes and therefore C changes).

In practical applications, the non-contact sensing element may also be an optical signal transmitter, and the optical signal transmitter may be configured to transmit an optical signal. Thus, the sensing member 101 can sense the triggering member 111 and generate a sensing signal by sensing the change of the optical signal.

In this embodiment of the present application, the microphone 10 may be provided with a controller and a noise reduction module, where the noise reduction module may be configured to execute a noise reduction mode; the controller may be electrically connected to the sensing element 101 and the noise reduction module, and the controller may be configured to control the noise reduction module to execute a noise reduction mode when the sensing element 101 senses the trigger 111 and generates an in-place sensing signal; and controlling the noise reduction module to close the noise reduction mode under the condition that the induction part does not sense the trigger part and generates an out-of-place sensing signal.

Specifically, a circuit board may be disposed in the microphone 10, and the sensing element 101, the controller, and the noise reduction module may all be disposed on the circuit board and electrically connected through an integrated circuit on the circuit board. The controller may include, but is not limited to, at least one of a combinational logic controller and a micro-program controller. The noise reduction module may be constituted by a logic circuit.

In this embodiment, the microphone may further include: a status sending module; the controller is electrically connected to the state sending module, and the controller may be further configured to control the state sending module to send the installation state information of the windproof piece 11 to the sound transmission device in communication connection with the microphone 10 under the condition that the sensing piece 101 senses the trigger piece 111 to generate an in-place sensing signal, so that the sound transmission device displays or broadcasts the installation state of the windproof piece 11.

For example, the manner in which the sound transmission device displays the installation state of the windshield 11 may include: the installation state of the windproof piece 11 is displayed on the screen by means of media contents such as characters and pictures, or the installation state of the windproof piece 11 is displayed by means of blinking or lighting an indicator light. The way in which the sound transmission device plays the installation state of the wind shield 11 includes voice prompt and the like. In practical application, the sound transmission device can also broadcast the installation state of the windproof piece 11 while displaying the installation state of the windproof piece 11, so that a user can know the installation state of the windproof piece 11 more intuitively.

Specifically, the sound transmission device may include, but is not limited to, at least one of a pan-tilt camera, a mobile phone, a tablet computer, and a personal computer, and in the embodiment of the present application, the sound transmission device is only used as the pan-tilt camera for example, and other types of sound transmission devices may be executed by reference.

Alternatively, the contact type triggering component may be a conductive component, and the contact type sensing component may be a current detection circuit.
