Description

Technical Field

[0001] The utility model relates to the technical field of microphones, in particular to an anti-interference wireless vehicle-mounted microphone. Background Art

[0002] As electric vehicles have attracted more and more attention and become more popular, more and more cars are equipped with on-board KTV and microphones, and the number of people who choose to buy on-board karaoke microphones and stay in the car to sing is also continuing to grow.

[0003] A microphone is an energy conversion device that converts sound signals into electrical signals. It is classified into dynamic, capacitor, electret and the recently emerging silicon micro-microphone. In addition, there are liquid microphones and laser microphones. Most microphones are electret capacitor microphones. Since the head of the microphone is mostly cylindrical or spherical, it can receive a large range of external sounds, and is easily interfered by surrounding sounds during use. Most wireless microphones nowadays are powered by batteries, and only the batteries need to be removed and replaced regularly. However, in the process of replacing the battery, an external force needs to be applied to the microphone to rotate its tail before the battery can be removed. However, when the tail rotates, the internal battery will also rotate with it, and the ends of the battery are tightly fitted with the positive and negative copper sheets in the microphone, which will cause the positive and negative copper sheets to rotate slightly, and eventually the negative copper sheet will be disconnected from the internal circuit of the microphone, resulting in the microphone being unable to continue to be used. For this reason, an anti-interference wireless car microphone is proposed. Utility Model Content

[0004] Based on this, the purpose of the utility model is to provide an interference-resistant wireless vehicle-mounted microphone to solve the technical problems raised in the above background.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0024] The following describes an embodiment of the utility model based on its overall structure.

[0025] An anti-interference wireless car microphone, such as Figures 1 to 7 As shown, it includes an insulating handle 100, the top of the insulating handle 100 is threadedly connected with a microphone tube 101, a battery hole 103 is opened at the center of the bottom end of the insulating handle 100, and a docking hole 104 is opened at both sides of the battery hole 103 at the bottom end of the insulating handle 100, the outer wall of the insulating handle 100 is sleeved with a handle tube assembly 120, and the top of the microphone tube 101 is rotatably provided with a mesh cover 110, and the curved inner wall of the mesh cover 110 is inlaid with a damping mesh layer 111.

[0026] The handle tube assembly 120 includes a handle tube 121 sleeved on the outer wall of the insulating handle 100, the top of the handle tube 121 is located at the lower half of the outer wall of the microphone tube 101 and is sleeved with a cone tube 125, the inner wall of the cone tube 125 is inlaid with a damping mesh cone 126, the bottom inner wall of the handle tube 121 is provided with a battery tube 123 extending into the battery hole 103, the bottom inner wall of the battery tube 123 is provided with a negative conductive sheet 127, and the top inner wall of the battery hole 103 is fixed with a positive conductive sheet;

[0027] A conductive core 124 is provided in the handle tube 121 below the battery tube 123 to connect the circuit with the negative conductive sheet 127. The top of the conductive core 124 extends into the power connection hole 104. The power connection hole 104 is provided with a conductive column to connect with internal components.

[0028] The curved inner wall of the handle tube 121 is provided with two groups of limiting strips 122 , and the outer wall of the insulating handle 100 is provided with limiting grooves 105 at the contact position between the two groups of limiting strips 122 .

[0029] The microphone tube 101 can be used normally by holding the handle tube 121 and placing it in front of the mouth, while the damping mesh layer 111 and the damping mesh cone 126 block the surrounding noise, so that it can only receive the sound transmitted from the front, which has a better effect of preventing noise interference;

[0030] When taking out the battery inside the microphone, hold the handle tube 121 tightly with one hand, and apply external force to the mesh cover 110 with the other hand to rotate it until the bottom end is separated from the cone tube 125, and then slide the handle tube 121 vertically downward along the insulating handle 100 until it is separated, and then turn the handle tube 121 upside down to take out the battery in the battery tube 123, and then put a new battery in, and then put the handle tube 121 on the outer wall of the insulating handle 100 from bottom to top again, and finally rotate the mesh cover 110 to dock with the cone tube 125;

[0031] When the mesh cover 110 is rotated, since the limit bar 122 is located in the limit groove 105, the handle tube 121 will not be active, and the battery will not rotate either, which can prevent damage to the negative conductive sheet 127 and the positive conductive sheet in the microphone, further improving the service life of the microphone. When the handle tube 121 is sleeved between the outer wall of the insulating handle 100, observe whether the limit bar 122 is aligned with the limit groove 105 to ensure that the conductive core 124 accurately enters the power connection hole 104, and ensures that the battery and the components inside the microphone are connected to the circuit. At the same time, the handle tube assembly 120 and the mesh cover 110 form a protective cover on the outer wall of the microphone, which can cope with the rigid contact caused by falling to the ground, further improving the protection effect of the microphone.

[0032] Please refer to Figure 1 A threaded docking ring 112 is fixed to the bottom edge of the mesh cover 110 , and an internal thread that matches the threaded docking ring 112 is formed on the inner wall of the top end of the cone 125 .

[0033] External force is applied to the mesh cover 110 to drive the threaded docking ring 112 to rotate, so that it can be separated from the cone 125, and finally the handle tube assembly 120 can be removed to replace the internal battery.

[0034] Please refer to Figure 1 and Figure 2 The curved outer wall of the insulating handle 100 is provided with two groups of buttons 102 , and the outer wall of the handle tube 121 is provided with two groups of silicone buttons at positions corresponding to the buttons 102 .

[0035] The volume of the microphone can be increased or decreased by holding the handle tube 121, or the microphone can be turned on or off by pressing two groups of buttons simultaneously.

[0036] Please refer to Figure 1 The insulating handle 100 is made of insulating rubber, and the curved outer wall of the insulating handle 100 is provided with anti-slip grooves.

[0037] The battery circuit is blocked to ensure that the components in the microphone can be stably powered. Anti-slip grooves are used to increase the roughness of the outer wall to ensure that it will not slip easily when held in the hand.

[0038] Although an embodiment of the utility model has been shown and described, this specific embodiment is merely an explanation of the utility model and is not a limitation of the utility model. The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiments without creative contributions as needed without departing from the principles and purpose of the utility model. However, as long as they are within the scope of the claims of the utility model, they are protected by patent law.
