Description

Technical Field

[0001] The present invention relates to the technical field of head-mounted hearing earphones, in particular to head-mounted hearing earphones. Background Art

[0002] Headphones, as the name implies, are worn on the head, not inserted into the ear canal, and are different from in-ear earplugs. They consist of two parts, a signal transmitter and headphones with signal receiving and amplifying devices (usually dynamic). The transmitter is connected to the signal source, and a preamplifier or headphone amplifier can also be connected in front of the transmitter to improve the sound quality and adjust the timbre.

[0003] In the English listening class, each student is equipped with a multi-function display device and headphones. The existing headphones are equipped with an indispensable sponge layer to achieve the effect of eliminating sound insulation and ensure the listening environment. However, the sponge layer is easy to press the ears when worn, which is inconvenient to adjust, making the back of the ears tightly pressed against the head. Over a long period of time (a university class is no less than 90 minutes), it causes blood circulation in the ears and increased discomfort. For this reason, we propose head-mounted listening headphones. Summary of the invention

[0004] The object of the present invention is to provide a head-mounted hearing headset which is easy to operate and prevents the ears from being squeezed, so as to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a head-mounted hearing headset, comprising a main frame with elastic contraction performance, wherein fixed rings are provided at both ends of the main frame, and a sponge layer is rotatably fitted on the outer surface of the fixed ring; further comprising a flipping assembly, wherein the flipping assembly for flipping the sponge layer is arranged on the fixed ring; and a control assembly, wherein the control assembly for controlling the operation of the flipping assembly is arranged on the main frame.

[0006] Preferably, the flip assembly includes a pressure plate located in the middle of the fixed ring, a telescopic rod with an elastic part inside is hingedly connected to the outer side of the pressure plate in a circular matrix arrangement, a connecting rod fixedly connected to the sponge layer is fixedly connected to the end of the telescopic rod, a plurality of arc rods are arranged in a circular matrix around the pressure plate, a movable ring mounted on the telescopic rod is rotatably connected between two adjacent arc rods, and a rotating assembly for driving the sponge layer to rotate is provided on the outer surface of the telescopic rod.

[0008] Preferably, the control component includes a sleeve fixedly connected to the fixed collar, a movable plate is sleeved in the sleeve, a slide is fixedly connected to the bottom of the movable plate, the middle part of the slide is an inclined structure, a pressure rod is fixedly connected to the middle part of the pressure plate and presses with the slide, an L-shaped rod is fixedly connected to the pressure rod, and a second L-shaped limiting plate is fixedly connected to the end of the L-shaped rod and slides with the pressure plate.

[0009] Preferably, the control component also includes a rotating rod rotatably connected to the main frame, the rotating rod is provided with a sliding groove slidably matched with the movable plate, and the upper and lower parts of the rotating rod are provided with limit rods fixedly connected to the movable plate. The outer surface of the rotating rod is rotatably connected to a first rotating shaft, and an elastic pull rope is hung on the first rotating shaft, and one end of the elastic pull rope is hung with a second rotating shaft rotatably connected to the main frame.

[0010] Preferably, a connecting plate is fixedly connected between the fixing ring and the main frame, and a notch movably matched with the connecting plate is provided on the sponge layer to avoid spatial obstruction during the flipping of the sponge layer.

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

The outer surface of the fixed ring 2 is rotatably matched with a sponge layer 3; it also includes a flip component 4, and the flip component 4 for flipping the sponge layer 3 is arranged on the fixed ring 2; the control component 17 is used to control the operation of the flip component 4 and is arranged on the main frame 1.

[0029] See also Figure 4 and Figure 8-Figure 9 The flip assembly 4 shown in the figure includes a pressure plate 5 located in the middle of the fixed ring 2, and a telescopic rod 6 with an elastic member inside is hingedly arranged in a circular matrix on the outside of the pressure plate 5. The end of the telescopic rod 6 is fixedly connected to a connecting rod 7 connected and fixed to the sponge layer 3. A plurality of arc rods 8 are arranged in a circular matrix around the pressure plate 5, and a movable ring 9 mounted on the telescopic rod 6 is rotatably connected between two adjacent arc rods 8. A rotating assembly 10 for driving the sponge layer 3 to rotate is provided on the outer surface of the telescopic rod 6.

[0032] In this embodiment, the movable plate 19 is moved along the sleeve 18 to move the slide plate 20 downward, thereby pressing the pressing rod 21, driving the pressing plate 5 and the pressing block 32 to move toward the ear. The pressing plate 5 moves under the action of the self-rotating movable ring 9, driving the telescopic rod 6 to rotate (taking the position of the movable ring 9 as the rotation fulcrum), and cooperates with the connecting rod 7 to make the outer ring of the sponge layer 3 flip open along the fixed sleeve ring 2, and then the pressing block 32 contacts the middle of the ear, which is convenient for rapid positioning and also plays a role in positioning correction. The position of the main frame 1 and the fixed sleeve ring 2 can be adjusted to avoid inaccurate position, resulting in poor silencing effect of the sponge layer 3, and then the movable plate 19 is reversed to make the sponge layer 3 flip back and wrap the back of the ear. On the one hand, it reduces the pressure on the front of the ear and expands the sound receiving area. On the other hand, it avoids squeezing the ear, making the ear tightly pressed against the head, causing discomfort.
