Description

Technical Field

[0001] The utility model relates to a microphone mesh cover, in particular to a protective microphone mesh cover. Background Art

[0002] The scientific name of microphone is microphone, also known as microphone, micro-phone. Microphone is an energy conversion device that converts sound signals into electrical signals. There are dynamic, condenser, electret and the recently emerging silicon micro-microphone, in addition to liquid microphones and laser microphones. Most microphones are electret condenser microphones, which work on the principle of using a polymer material vibration membrane with permanent charge isolation. The mesh cover of the microphone protects the microphone core inside.

[0003] Since there are ventilation holes on the mesh, dust and saliva can enter the microphone core through the ventilation holes, accumulating dust and germs, causing hygiene problems. In addition, the microphone is usually placed horizontally on the table after use, which can cause dust on the table and accidentally spilled wine to enter the mesh, affecting the normal use of the microphone. Utility Model Content

[0004] The utility model aims to provide a protective microphone mesh cover, which can solve the problem that dust or liquid easily enters into the conventional microphone mesh cover.

[0005] The purpose of this utility model is achieved through the following technical solutions:

[0006] A protective microphone mesh cover comprises a shell and a protective cover rotatably mounted on the shell. The upper part of the shell is set as a spherical mesh cover. The inner wall of the protective cover fits the spherical mesh cover. A plurality of first ventilation holes are evenly arranged on the spherical mesh cover. A plurality of second ventilation holes are evenly arranged on the protective cover. The number and size of the first ventilation holes are the same as the number and size of the second ventilation holes, and the positions of the first ventilation holes correspond to the positions of the second ventilation holes.

[0007] Preferably, an annular groove for mounting the protective cover is provided on the outer side of the shell.

[0008] Preferably, a limiting plate is provided on the top of the annular groove, and a damping pad is provided on the inner bottom of the annular groove.

[0009] Preferably, an annular clamping plate is provided at the bottom of the protective cover.

[0010] Preferably, at least two clamping blocks are equidistantly arranged on the upper surface of the annular clamping plate.

[0011] Preferably, at least two slots are equidistantly arranged on the lower surface of the limiting plate.

[0012] The utility model controls the first ventilation hole and the second ventilation hole to overlap or stagger, thereby controlling the communication between the internal and external environments of the spherical mesh cover. When the first ventilation hole and the second ventilation hole are staggered, the interior of the spherical mesh cover is not connected to the external environment, preventing dust and liquid from entering.

Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of the present disclosure.

[0020] Embodiment 1

[0021] The utility model controls the first ventilation hole and the second ventilation hole to overlap or stagger, thereby controlling the communication between the internal and external environments of the spherical mesh cover. When the first ventilation hole and the second ventilation hole are staggered, the interior of the spherical mesh cover is not connected to the external environment, preventing dust and liquid from entering.

[0022] like Figure 1-2As shown, a protective microphone mesh cover comprises a shell 1 and a protective cover 2 rotatably mounted on the shell 1. The upper portion of the shell 1 is provided with a spherical mesh cover 11. The inner wall of the protective cover 2 fits the spherical mesh cover 11. A plurality of first ventilation holes 111 are evenly arranged on the spherical mesh cover 11. A plurality of second ventilation holes 21 are evenly arranged on the protective cover 2. The number and size of the first ventilation holes 111 are the same as the number and size of the second ventilation holes 21, and the positions of the first ventilation holes 111 correspond to the positions of the second ventilation holes 21, ensuring that the first ventilation holes 111 and the second ventilation holes 21 can overlap.

[0023] Furthermore, an annular groove 12 for mounting the protective cover 2 is provided on the outer side of the housing 1 .

[0024] like Figure 3 As shown, further, a limit plate 121 is provided at the top of the annular groove 12. A damping pad 122 is provided at the inner bottom of the annular groove 12. The function of the damping pad 122 is to increase the damping feeling when the annular clamping plate 22 rotates in the annular groove 12, so as to prevent the protective cover 2 from excessively rotating on the outer side of the housing 1.

[0025] Furthermore, an annular clamping plate 22 is provided at the bottom of the protective cover 2. The annular clamping plate 22 is installed in the annular groove 12, and the annular clamping plate 22 rotates in the annular groove 12, so that the protective cover 2 can stably rotate around the housing 1 to achieve the opening and closing function.

[0026] Furthermore, at least two blocks 221 are arranged equidistantly on the upper surface of the annular clamping plate 22. The blocks 221 are mutually engaged with the clamping groove 1211 described below, and their function is to prevent the protective cover 2 from excessively rotating outside the shell 1 and to enhance the overall structural strength. At the same time, when the annular clamping plate 22 rotates 360° in the annular groove 12, the first ventilation hole 111 overlaps with the second ventilation hole 21, and the internal and external environments of the shell 1 are connected; when rotating to other angles, the first ventilation hole 111 is staggered with the second ventilation hole 21, and the internal and external environments of the shell 1 are not connected.

[0027] Furthermore, at least two slots 1211 are equidistantly arranged on the lower surface of the limiting plate 121. The size and number of the block 221 and the slot 1211 are the same, ensuring that the block 221 and the slot 1211 can be engaged with each other.

[0028] Working principle:

[0029] When the protective cover 2 is rotated to the closed position, the clamping block 221 is just embedded in the clamping slot 1211, so that the protective cover 2 and the housing 1 are firmly fixed, and the protective cover 2 is prevented from accidentally rotating due to misoperation.

[0030] The protective cover 2 is rotatably mounted on the housing 1 and can be rotated to an open or closed position as required. When the protective cover 2 is closed, its inner wall fits tightly against the spherical mesh cover 11 to form a closed barrier, effectively preventing accidental collisions, liquid splashing or other external factors from causing damage to the microphone.

[0031] The first ventilation holes 111 and the second ventilation holes 21 have the same number and size and corresponding positions. When the protective cover 2 is closed, the first ventilation holes 111 and the second ventilation holes 21 overlap precisely, ensuring that sound can still enter the shell 1 unimpeded and reach the microphone diaphragm, thereby maintaining the normal sound pickup performance of the microphone.

[0032] In the description of the present invention, it should be understood that the terms "middle", "length", "up", "down", "front", "back", "vertical", "horizontal", "inside", "outside", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0033] In the present invention, unless otherwise clearly specified and limited, the first feature "on" the second feature may be that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. "Multiple" means at least two, such as two, three, etc., unless otherwise clearly and specifically limited.

[0034] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral one; it can be a mechanical connection, an electrical connection, or communication with each other; 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, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0035] The above is only for explaining the implementation mode of the utility model and is not used to limit the utility model. For those skilled in the art, any modification, equivalent substitution, improvement, etc. made within the spirit and principle of the utility model without creative work should be included in the protection scope of the utility model.
