TECHNICAL FIELD

[0001] The application belongs to the technical field of microphone equipment, and particularly relates to a microphone with a fixing assembly BACKGROUND

[0002] A microphone is also called a microphone, a kind of electroacoustic equipment, belonging to a microphone, a transducer for converting sound into electricity. When the vibration of sound is transmitted to the diaphragm of the microphone, the magnet inside is pushed to form a changing current. The changing current is sent to the rear sound processing circuit for amplification and processing. The sound wave acts on the electroacoustic element to generate a voltage, which is then converted into electrical energy. It can be used in various sound amplification equipment. There are many types of microphone equipment in the prior art, but the following problems often occur in actual use:

[0003] (1) In the existing microphone equipment, different types of microphones are used according to different scenes. For example, a microphone with a support is often used in a conference room, while a handheld microphone is often used in a stage scene. However, there are few microphones in the prior art that can simultaneously meet the above two requirements. The microphone includes a substrate and a shell arranged above the substrate. The upper surface of the substrate is provided with a diaphragm and various chips. The chips are directly attached to the upper surface of the substrate. When the chips are working normally or receiving sound signals, heat will be generated. The heat cannot be conducted to the outside environment in time, causing thermal disturbance of the air in the back cavity of the microphone, forming thermal noise, and reducing the noise reduction performance of the microphone.

DETAILED DESCRIPTION ​

[0030] The present invention will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present invention and should not be construed as limiting the scope of protection of the present invention. Those skilled in the art can make some non-essential improvements and adjustments to the present invention based on the above-described contents.

[0031] Example 1

[0032] like Figure 1 As shown, this embodiment provides a microphone with a fixing component.

[0033] The microphone includes a microphone receiving section 1, a handheld part 6, and a substrate 11 disposed inside the microphone receiving section 1. The substrate 11 is provided with a diaphragm and various integrated chips, which are the heat source parts of the microphone. The handheld part 6 has clearance holes 19 on both ends. The clearance holes 19 are the insertion holes for the microphone fixing components to assist in installation. The microphone receiving section 1 is provided with heat dissipation holes 4 with filters, and the handheld part 6 is provided with a switch part 3.

[0034] Combination Figure 3 and 4 A heat-conducting frame is provided below the substrate 11 and inside the handheld part 6. The heat-conducting frame includes a T-shaped plate 12 and a horizontal plate 13 arranged in parallel, and a positioning component 14 disposed between the T-shaped plate 12 and the horizontal plate 13. The positioning component 14 includes two positioning rods 143 arranged in parallel.

[0035] In this embodiment, by providing a heat-conducting frame inside the handheld part 6, the heat on the substrate 11 can be conducted along the heat-conducting frame, so that the heat in the space where the chip is located can be conducted to the outside, preventing the generation of hot air and thermal noise in the microphone.

[0036] The fixing assembly includes a bracket body 2 that is installed in conjunction with the handheld part 6. The bracket body 2 includes a U-shaped base 21 and locking buttons 22 located on both sides of the upper end of the U-shaped base 21. The upper side of the U-shaped base 21 is provided with an elastic reset member for the locking button 22 to reset in the horizontal direction. The side of the locking button 22 is provided with a U-shaped groove 23 that matches the shape of the side of the positioning rod 143. The elastic reset member is specifically a structure that provides elastic force when the locking button 22 moves at the upper end of the U-shaped base 21, such as a telescopic spring located between the locking button 22 body and the upper channel of the U-shaped base 21.

[0037] It is understood that when the bracket body 2 is in use, by pulling the locking button 22 outward in the horizontal direction, the locking button 22 is aligned with the clearance hole 19. Under the action of the elastic force accumulated by the elastic reset member when the locking button 22 is pulled, the U-shaped groove 23 can directly abut against the side of the positioning rod 143, thereby completing the installation and fixation of the microphone and the bracket body 2.

[0038] Further, the heat-conducting frame, the U-shaped base 21 and the locking knob 22 are all made of heat-conducting alloy materials.

[0039] In the embodiment, the heat-conducting frame not only realizes heat conduction inside the handheld part 6, but also transmits heat to the support body 2, that is, the heat-conducting frame not only realizes the heat dissipation function, but also serves as a limiting part when the support body 2 is installed, achieving two purposes at once.

[0040] In combination with Figure 3 Further, the heat-conducting frame cover space is provided with a battery compartment 16, the outer wall of the handheld part 6 is provided with a compartment cover 18 for covering the battery compartment 16 in the vertical direction, the side wall of the handheld part 6 is provided with a press button 5 for assisting in controlling the opening and closing of the compartment cover 18, and the T-shaped plate 12 and the horizontal plate 13 are further provided with a sliding rail 15 for the sliding of the compartment cover 18.

[0041] During the actual long-time work of the microphone, the battery at the back thereof will also be discharged for a long time and heat will be generated, that is, a certain amount of heat will also exist inside the battery compartment 16. The battery compartment 16 is arranged in the heat-conducting frame cover space, so that the heat generated during the daily work of the battery compartment 16 can be conducted.

[0042] In combination with Figure 4 , 5 , 6, 7, further, the positioning rod 143 is rotatably arranged between the T-shaped plate 12 and the horizontal plate 13, the positioning rod 143 further has a certain rotation clearance, the positioning assembly 14 further includes a base 141 arranged at the end of the positioning rod 143, a positioning sleeve 142 arranged at the upper end of the base 141, and two arc-shaped lugs 144 asymmetrically arranged on the positioning rod 143, wherein a magnet one 145 is embedded at the center position of the surface of the arc-shaped lug 144;

[0043] The compartment cover 18 is arranged towards the arc-shaped lug 144, and the end of the connecting shaft 51 of the press button 5 is also provided with a U-shaped abutting part 52, and a magnet two 521 is arranged at the center position of the U-shaped abutting part 52 to cooperate with the magnet one 145 for adsorption;

[0044] The magnet two 521 on the press button 5 has a greater magnetization strength than the magnet one 145 on the positioning rod 143.

[0045] In combination with Figure 6In the embodiment, the microphone is in working state, the cover 18 on the battery compartment 16 is in closed state, in this state, the U-shaped abutting portion 52 on the side of the cover 18 is in abutment with one of the arc-shaped protrusions 144 on the positioning rod 143, which is caused by the attraction force of the magnet one 145 and the magnet two 521, when it is needed to replace the battery by pushing the cover 18 upward, the pressing button 5 is pressed inward, since the magnetization intensity of the magnet two 521 on the pressing button 5 is greater than that of the magnet one 145 on the positioning rod 143, the magnet two 521 on the pressing button 5 will attract the arc-shaped protrusion 144 in the corresponding position to drive the positioning rod 143 to rotate, then, the other arc-shaped protrusion 144 will be separated from the U-shaped abutting portion 52 on the side of the cover 18, at this time, the cover 18 can be pushed upward to replace the battery.

[0046] It should be noted that the positioning rod 143 in the application can not only conduct heat as part of the heat conduction frame in the microphone, but also assist as the clamping component of the cover 18 of the battery compartment 16, compared with the hard plastic buckle of the battery compartment cover plate in the prior art, the service life of the arc-shaped protrusion 144 and the U-shaped abutting portion 52 is longer, and the fixing function of the cover 18 is not increased by too much structure, and the internal space of the handheld part 6 is reasonably utilized.

[0047] In combination Figure 5 Further, the lower end of the positioning rod 143 is rotationally connected with the base 141, the positioning rod 143 is sleeved with the spring 146 in the positioning sleeve 142, the U-shaped abutting portion 52 on the pressing button 5 is separated from the arc-shaped protrusion 144 on the upper end of the positioning rod 143 under the elastic restoring force of the elastic restoring member on the edge of the pressing button 5 after the pressing button 5 is released, at this time, the positioning rod 143 is rotated and reset under the elastic force of the spring 146, then the arc-shaped protrusion 144 on the lower end of the positioning rod 143 can be rotated into the U-shaped abutting portion 52 on the side of the cover 18 under the magnetic attraction force to fix the cover 18.

[0048] Further, the lower end of the handheld part 6 is provided with an opening, the horizontal plate member 13 is located in the opening, and the lower end of the horizontal plate member 13 is uniformly provided with a plurality of heat dissipation fins 131, the heat can be quickly transferred to the lower end of the whole microphone through the opening and the heat dissipation fins on the lower end to be discharged.

[0049] Further, the side wall of the hand-held part 6 is provided with a limiting passage 17 through which the pressing button 5 passes, and the inner wall of the limiting passage 17 and the connecting shaft 51 are provided with an elastic reset member. The above embodiments are only used to illustrate the technical solutions of the present application, but not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that the technical solutions recorded in the foregoing embodiments can still be modified, or some technical features can be replaced equivalently; and these modifications or replacements do not drive the essence of the corresponding technical solutions out of the spirit and scope of the technical solutions of the embodiments of the present application.
