[0002] In a hearing test, it is necessary to accurately place the earphone on the ear of the test subject to ensure that the sound can be correctly transmitted into the ear. The earphone cover can help fix the earphone and keep it in a proper position, avoiding the influence on the test result due to the displacement of the earphone. At the same time, the soft material of the earphone cover can reduce the pressure of the earphone on the ear, improve the comfort of the test subject wearing the earphone, and enable them to complete the test in a relatively relaxed state.

[0003] When the existing special earphone cover for head-mounted hearing tests is worn, the ear is covered by the earcup part, making it easy for the heat of the ear to accumulate and cause fever, thus affecting the comfort.

[0004] Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies, and a special earphone cover for hearing tests is proposed. Summary of the Invention

[0005] Aiming at the deficiencies of the prior art, the present invention provides a special earphone cover for hearing tests, which solves the problems raised in the above background art.

[0006] To achieve the above purposes, the present invention is realized through the following technical solutions: A special earphone cover for hearing tests, including an earcup shell and a water circulation cooling component. The water circulation cooling component is arranged inside the outer side surface of the earcup shell. The water circulation cooling component includes a silent motor, a spring telescopic rod, a first gear, a second gear, a water droplet wheel, a water storage tank, a circulation pipe, a capillary network, and an elastic piston rod. The output end of the silent motor is fixed with a spring telescopic rod, and the outer wall of the spring telescopic rod is fixed with a first gear. The side of the first gear is meshed with a second gear, and the surface of the second gear is fixed with a water droplet wheel. A water storage tank is also arranged inside the outer side surface of the earcup shell, and both ends of the water storage tank are connected with a circulation pipe. The middle section of the circulation pipe is connected with a capillary network. The side of the water storage tank is provided with an elastic piston rod in a penetrating manner.

[0007] Further, the elastic piston rod and the water droplet wheel are at the same height, and the end of the elastic piston rod is in a round head structure.

[0008] Further, the inner side surface of the earcup shell is provided with a silica gel ear pad, and the capillary network is located on the side of the silica gel ear pad.

[0009] Further, the capillary network is in a circular ring structure, and a broadcast speaker is arranged at the circular hole position of the capillary network.

[0010] Further, the end of the spring telescopic rod has a pentagonal structure. An electromagnet sheet is sleeved on the outer wall of the output shaft of the silent motor, and the electromagnet sheet is close to the tail end of the spring telescopic rod.

[0011] Further, a winding and unwinding wheel is rotatably connected inside the earcup housing towards the pentagonal end of the spring telescopic rod.

[0012] Further, a first turntable is fixed on the surface of the winding and unwinding wheel, and a pentagonal groove is formed on the surface of the first turntable.

[0013] Further, a second turntable is meshed and connected to the side of the first turntable, a winding disc is fixed on the side of the second turntable, and the first turntable is drivingly connected to the second turntable through a transmission belt.

[0014] Further, a steering wheel is arranged in parallel on one side of the winding disc, and a wire is threaded through the surface of the steering wheel.

[0015] Further, one end of the wire is wound inside the winding disc, and the other end of the wire is connected to a pickup. The pickup penetrates through the earcup housing, and the surface of the pickup is closely attached to the surface of the winding and unwinding wheel.

[0016] The present invention provides a special earphone for hearing test, which has the following beneficial effects:

[0017] 1. For this special earphone for hearing test, through the capillary network closely attached to the side of the silica gel earpad, when the silent motor starts, the cooling water body circulates uniformly along the storage tank, the circulation pipe and the inside of the capillary network, so as to continuously take away the heat of the wearer's ear, thereby preventing the wearer from feeling uncomfortable due to overheating of the ear caused by long-term wearing of this special earphone for hearing test. Moreover, the round hole position in the middle of the capillary network is used to set the broadcast speaker, and the sound directly passes through the round hole and enters the ear, so as to avoid the influence of the circulating water body on the sound and make the played sound timbre inaccurate.

[0018] 2. For this special earphone for hearing test, while meeting the ear cooling requirement to improve the wearing comfort according to the use demand, the forward and reverse rotation of the output shaft of the silent motor and the energization and de-energization of the electromagnet sheet can be freely controlled to realize the extension and retraction of the pickup. When the pickup extends, it can be close to the mouth to clearly pick up the human voice, and when the pickup retracts, it can prevent it from hindering the mouth movement when the monitoring function is not used, such as eating snacks. Secondly, the retraction of the pickup can protect the pickup line part and reduce the overall volume for convenient carrying. Moreover, the rotation direction of the winding disc is adapted to the telescopic direction of the pickup, so as to automatically release or wind the wire when the pickup telescopes, so as to avoid the phenomenon of pulling and breaking or messy distribution caused by the wire being too short or too long.

[0025] The following further describes in detail the embodiments of the present invention in conjunction with the drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0026] As Figures 1-5As shown in the figure, the present invention provides a technical solution: a special earplug for hearing tests, comprising an earcup shell 1 and a water circulation cooling component 2. The water circulation cooling component 2 is arranged inside the outer side surface of the earcup shell 1. The water circulation cooling component 2 includes a silent motor 201, a spring telescopic rod 202, a first gear 203, a second gear 204, a water droplet wheel 205, a water storage tank 206, a circulation pipe 207, a capillary network 208 and an elastic piston rod 209. The output end of the silent motor 201 is fixed with the spring telescopic rod 202, and the outer wall of the spring telescopic rod 202 is fixed with the first gear 203. The side surface of the first gear 203 is meshed with the second gear 204, and the surface of the second gear 204 is fixed with the water droplet wheel 205. The outer side surface of the earcup shell 1 is also provided with the water storage tank 206 inside, and both ends of the water storage tank 206 are connected with the circulation pipe 207. The middle section of the circulation pipe 207 is connected with the capillary network 208. The elastic piston rod 209 penetrates through the side surface of the water storage tank 206. The elastic piston rod 209 and the water droplet wheel 205 are at the same height, and the end of the elastic piston rod 209 is in a round head structure. The inner side surface of the earcup shell 1 is provided with a silica gel ear wrap 3, and the capillary network 208 is located on the side surface of the silica gel ear wrap 3. The capillary network 208 is in a circular ring structure, and a broadcast speaker is arranged at the circular hole position of the capillary network 208;

[0027] The specific operation is as follows. The silica gel ear wrap 3 wraps the wearer's ear. The sound of the wearer is recorded by the pickup 11, and after being processed, it is played through the broadcast speaker at the wearer's ear, thereby realizing the monitoring effect, enabling the wearer to adjust the subsequent sound according to his own voice. After the special earplug for hearing tests is worn, the silent motor 201 drives the spring telescopic rod 202 to rotate, causing the first gear 203 to engage the second gear 204 to drive the water droplet wheel 205 to rotate. Each time the water droplet wheel 205 rotates one week, it will squeeze the elastic piston rod 209 once, causing the elastic piston rod 209 to perform a piston movement along the inside of the water storage tank 206, so that the water body inside the water storage tank 206 circulates uniformly along the inside of the circulation pipe 207 and the capillary network 208. The water body entering the capillary network 208 can absorb the heat of the human ear through the silica gel ear wrap 3, and the circular hole position in the middle of the capillary network 208 is used to set the broadcast speaker to prevent the water body from affecting the sound played by the speaker;

[0028] Based on the above description, through the capillary network 208 closely attached to the side surface of the silica gel ear wrap 3, when the silent motor 201 is started, the cooling water body circulates uniformly along the inside of the water storage tank 206, the circulation pipe 207 and the capillary network 208, so as to continuously take away the heat of the wearer's ear, thereby preventing the wearer from feeling uncomfortable due to overheating of the ear caused by long-term wearing of the special earplug for hearing tests. Moreover, the circular hole position in the middle of the capillary network 208 is used to set the broadcast speaker, and the sound directly passes through the circular hole and enters the ear, so as to avoid the circulating water body from affecting the sound and causing the played sound timbre to be inaccurate.

[0029] As shown Figures 1-5 in the figure, the end of the spring telescopic rod 202 has a pentagonal structure. An electromagnet sheet 4 is sleeved on the outer wall of the output shaft of the silent motor 201, and the electromagnet sheet 4 is close to the tail end of the spring telescopic rod 202. The pentagonal end of the spring telescopic rod 202 faces the inside of the earcup shell 1 and is rotatably connected with a take-up reel 5. A first turntable 6 is fixed on the surface of the take-up reel 5, and a pentagonal groove is formed on the surface of the first turntable 6. A second turntable 7 is meshed and connected to the side of the first turntable 6, and a winding reel 8 is fixed to the side of the second turntable 7. Moreover, the first turntable 6 is in transmission connection with the second turntable 7 through a transmission belt. A turning wheel 9 is arranged in parallel on one side of the winding reel 8, and a wire 10 is passed through the surface of the turning wheel 9. One end of the wire 10 is wound inside the winding reel 8, and the other end of the wire 10 is connected with a pickup 11. The pickup 11 penetrates through the earcup shell 1, and the surface of the pickup 11 is closely attached to the surface of the take-up reel 5;

[0030] The specific operation is as follows. When wearing this special earphone for hearing test and without singing monitoring, the electromagnet sheet 4 adsorbs the end of the movable rod of the spring telescopic rod 202 to compress the spring. At this time, the spring telescopic rod 202 is in a contracted state. At this time, the pentagonal end of the spring telescopic rod 202 is separated from the first turntable 6. At this time, the silent motor 201 starts to only realize the function of circulating cooling water to cool the ear. When wearing this special earphone for hearing test and singing monitoring is needed, the electromagnet sheet 4 is powered off, so that the spring telescopic rod 202 elastically extends, and its pentagonal end is inserted into the pentagonal groove, so that the first turntable 6 drives the take-up reel 5 to rotate. The take-up reel 5 rotates to apply a thrust to the wire sleeve part of the pickup 11, so that the pickup 11 extends out of the earcup shell 1, so that the pickup 11 can be close to the mouth to clearly pick up the human voice;

[0031] Similarly, when the pickup 11 is not in use, the output shaft of the silent motor 201 rotates in the reverse direction to make the take-up reel 5 rotate in the reverse direction to retract the pickup 11 into the earcup shell 1 to avoid the pickup 11 always being located at the mouth and affecting the movement of the mouth;

[0032] When the first turntable 6 rotates, it will drive the second turntable 7 connected to it in transmission to drive the winding reel 8 to rotate. The rotation direction of the winding reel 8 is the same as that of the take-up reel 5. When the pickup 11 extends out, the winding reel 8 releases the wire 10, so that the pickup 11 can pick up the human voice and transmit it through the wire 10. When the output shaft of the silent motor 201 rotates in the reverse direction, the pickup 11 is retracted into the earcup shell 1. At the same time, the winding reel 8 rotates in the reverse direction to wind up the wire 10 to prevent the wire 10 from being distributed in a mess inside the earcup shell 1;

[0033] Based on the above description, according to the use requirements, while meeting the ear cooling to improve wearing comfort, the forward and reverse rotation of the output shaft of the silent motor 201 and the power on and off of the electromagnet sheet 4 can be freely controlled to realize the extension and retraction of the pickup 11. The pickup 11 can be extended close to the mouth to clearly pick up the human voice, and the pickup 11 can be retracted to prevent it from hindering the mouth movement when the monitoring function is not used, such as eating snacks. Secondly, the retracted pickup 11 can protect the circuit part of the pickup 11 and reduce the overall volume for easy carrying. Moreover, the rotation direction of the reel 8 is adapted to the extension and retraction direction of the pickup 11, so as to automatically release or reel in the wire 10 when the pickup 11 is extended and retracted, so as to avoid the wire 10 being pulled and broken or distributed messily due to being too short or too long.

[0034] In summary, when the special earmuffs for hearing test are used, the silicone earmuffs 3 are first wrapped around the wearer's ears, and the wearer's voice is recorded by the microphone 11. After the recording is processed, the recording is played back to the wearer's ears through the broadcasting speaker, thereby achieving a monitoring effect, allowing the wearer to adjust the subsequent sound according to his own voice. After the special earmuffs for hearing test are worn, the mute motor 201 drives the spring telescopic rod 202 to rotate, so that the first gear 203 engages the second gear 204 and drives the water drop wheel 205 to rotate. The water drop wheel 205 squeezes the elastic piston rod 209 once every rotation, so that the elastic piston rod 209 performs a piston motion along the inside of the water tank 206, so that The water in the water tank 206 circulates at a uniform speed along the circulation pipe 207 and the capillary network 208. When the water enters the capillary network 208, it can absorb the heat from the human ear through the silicone ear pad 3. The circular hole in the middle of the capillary network 208 is used to set the broadcasting speaker to prevent the water from affecting the sound played by the speaker. The capillary network 208 is made of a metal sound-absorbing board. The specific size of the circular hole in the middle is obtained through experiments to ensure that the sound-absorbing material does not hinder the sound playback of the speaker. At the same time, the surface of the metal sound-absorbing board has small holes for storing electricity, which can absorb the sound of the circulating water to prevent the sound of the water flow from affecting the sound played by the speaker.

[0035] When the special earmuffs for hearing test are worn and there is no need to monitor singing, the electromagnet sheet 4 attracts the movable rod end of the spring telescopic rod 202 to compress the spring. At this time, the spring telescopic rod 202 is in a contracted state. At this time, the pentagonal end of the spring telescopic rod 202 is separated from the first turntable 6. At this time, the mute motor 201 is started to only realize the function of circulating cooling water to cool the ear. When the special earmuffs for hearing test are worn and there is a need to monitor singing, the electromagnet sheet 4 is powered off to make the spring telescopic rod 202 elastically extend, so that its pentagonal end is inserted into the pentagonal groove, so that the first turntable 6 drives the retracting wheel 5 to rotate. The rotation of the retracting wheel 5 applies a thrust to the wire sleeve part of the pickup 11, so that the pickup 11 extends from the inside of the earmuff shell 1, so that the pickup 11 can be close to the mouth to clearly pick up the human voice;

[0036] Similarly, when the pickup 11 is not in use, the output shaft of the mute motor 201 rotates in the reverse direction, causing the take-up and pay-off reel 5 to rotate in the reverse direction to retract the pickup 11 into the earcup housing 1, so as to prevent the pickup 11 from always being located at the mouth and affecting mouth movement;

[0037] While the first turntable 6 rotates, it drives the second turntable 7 connected thereto in transmission to carry the take-up reel 8 to rotate. The rotation direction of the take-up reel 8 is the same as that of the take-up and pay-off reel 5. When the pickup 11 extends out, the take-up reel 8 pays out the wire 10, so that the pickup 11 can pick up human voices and transmit them through the wire 10. When the output shaft of the mute motor 201 rotates in the reverse direction, the pickup 11 is retracted into the earcup housing 1. At the same time, the take-up reel 8 rotates in the reverse direction to wind up the wire 10, so as to prevent the wire 10 from being disorderly distributed inside the earcup housing 1.
