Description

Technical Field

[0001] This utility model relates to the technical field of hearing testing equipment, specifically to a novel integrated audiometer. Background Technology

[0002] An audiometer is an instrument that measures an individual's sensitivity to various frequencies. By comparing this sensitivity to normal hearing, the degree of hearing loss can be determined. Normal hearing ranges from 0 to 25 decibels (dB). When using an audiometer, the subject needs to clean their ears and the test should be conducted in a quiet environment. The instrument automatically provides stimuli of various frequencies from weak to strong, automatically changing the frequency. During the test, the subject wears closed, sound-isolating headphones. When a sound is heard, the subject presses a button, and the instrument directly plots an audibility curve based on the subject's response. However, in most audiometers currently on the market, the headphones and the main unit are typically separate. While this allows for simultaneous wearing of headphones in both ears to relatively isolate external sounds, the reliance on the electrical connection between the headphones and the main unit, and the sound frequency generated by the vibration of a paper disc within the relatively small internal space of the headphones, significantly affects the accuracy of the audiometer test. Furthermore, such instruments usually come with a single set of headphones, which are easily lost, and the use of the same set by different subjects can easily lead to bacterial transmission. Utility Model Content

[0003] To address the problems existing in the prior art, the present invention aims to provide a novel integrated audiometer. This invention features a compact structure, is easy to manufacture and use, and utilizes air conduction within the main body for more concentrated sound. The vibrating pad is also easy to fix and replace, resulting in more accurate vibration frequencies for easier hearing testing.

[0004] This utility model discloses a novel integrated audiometer, comprising a housing, a control panel on the front side of the housing, a cover on the rear side of the housing, a vibrating block and a vibrating plate inside the housing, the vibrating block being electrically connected to the control panel, and the vibrating plate being laid flat inside the housing; wherein, the vibrating plate includes a connecting portion on the periphery and a vibrating portion in the middle, the connecting portion being detachably connected to the housing, the middle of both ends of the vibrating portion along the length direction being connected to the connecting portion, and gaps being left between the other edges of the vibrating portion and the connecting portion, thereby forming a rectangular frame-shaped through groove on the vibrating plate, the vibrating block being located at the middle of both sides of the vibrating portion along the width direction; a protrusion adapted to the through groove is formed on the inner side of the middle of the cover, thereby forming a sound source chamber between the protrusion and the vibrating portion, and a notch is left on the outer side of the cover corresponding to the sound source chamber; a button is also provided on the side of the housing, the button being electrically connected to the control panel.

[0005] In one embodiment, the audiometer further includes ear accessories adapted to both ears of a human, the cover having permanent magnets around the perimeter corresponding to the notch, and the ear accessories having an attraction block adapted to the permanent magnets on the side away from the human ear.

[0006] In one embodiment, the outer side of the cover is in the shape of a funnel recessed into the box body at the location corresponding to the sound source chamber, the notch is located at the center of the funnel shape, and the ear accessory is adapted to the funnel shape.

[0007] In one embodiment, a gap is left in the middle of the box body for clamping the vibrating plate, and connecting rods are respectively provided at two corners of one end of the box body and in the middle of the other side. The connecting rods pass through the edge of the connecting part so that the vibrating plate is installed into the box body.

[0008] In one embodiment, the end of the connecting rod is tightly fitted to the housing by a soft pad.

[0009] In one embodiment, the cover is connected to the box body via a plug-in portion, the plug-in portion being located at the middle of both sides of the connection portion in the width direction, and the vibrating plate having a through hole with a diameter larger than that of the plug-in portion.

[0010] In one embodiment, the cover is embedded in one side of the box, and the other sides of the box are made of sound-insulating material.

[0011] Compared with the prior art, the beneficial effects of this utility model's technical solution are:

[0012] 1. This utility model has a compact structure and is easy to manufacture and use. Although it can only test one ear at a time, it can be used for both ears. The sound is conducted through air inside the main body. The sound source chamber makes the sound more concentrated, and the vibrating pad is easy to fix and replace, making the frequency generated by the vibration more accurate, so as to facilitate hearing testing.

[0013] 2. This utility model can use disposable or easy-to-clean and disinfect ear accessories. By wearing the ear accessory in the left or right ear, the subject can fit the cover of the audiometer and complete the hearing test of both ears with the same instrument. Although the audiometer needs to be relatively close to the human body, the isolation of the ear accessory can reduce the subject's ear contact with the audiometer and reduce the spread of bacteria.

Detailed Implementation

[0018] The accompanying drawings are for illustrative purposes only and should not be construed as limiting the scope of this patent. To better illustrate this embodiment, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.

[0019] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can be described as the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0020] like Figures 1-3As shown, this utility model discloses a novel integrated audiometer, comprising a housing 1, a control panel 2 on the front side of the housing 1, a cover 3 on the rear side of the housing 1, a vibrating block 4 (not shown) and a vibrating plate 5 inside the housing 1. The vibrating block 4 is electrically connected to the control panel 2, and the vibrating plate 5 is laid flat inside the housing 1. The vibrating plate 5 includes a connecting portion 51 on the periphery and a vibrating portion 52 in the middle. The connecting portion 51 is detachably connected to the housing 1, and the vibrating portion 52 is located at the middle of both ends along its length. The vibrating part 52 is connected to the connecting part 51, and gaps are left between the other edges of the vibrating part 52 and the connecting part 51, thereby forming a rectangular frame-shaped through groove on the vibrating plate 5. The vibrating block 4 is located at the middle of both sides of the vibrating part 52 along the width direction. A protrusion 31 adapted to the through groove is formed on the inner side of the middle part of the cover 3, thereby forming a sound source chamber between the protrusion 31 and the vibrating part 52. A notch is left on the outer side of the cover 3 corresponding to the sound source chamber. A button 6 is also provided on the side of the box 1, and the button 6 is electrically connected to the control panel 2. This utility model has a compact structure and is easy to manufacture and use. Although it can only test one ear at a time, it can be used for both ears. The sound is conducted through the air inside the body. Since a relatively closed sound source chamber is formed between the protrusion 31 and the vibrating part 52, its setting allows the sound to be output more concentratedly from the notch. The vibrating plate 5 is also easy to fix and replace, making the frequency generated by the vibration more accurate, so as to facilitate hearing testing. During use, the user adjusts the vibration frequency of the vibrating block 4 and other procedures via the control panel 2 to prepare for the test. The test subject directly places the box 1 close to their ear and listens to the sound through the notch in the cover 3. When the vibrating block 4 vibrates, the two ends of the vibrating part 52 of the vibrating plate 5 are relatively fixed by the connecting part 51. The vibrating part 52 vibrates in a similar up-and-down rotational manner along the width direction, causing the air in the sound source chamber to vibrate and thus producing sound, which is concentrated and output through the notch. If the test subject hears the sound, they can press the button 6 on the side of the box 1; if they do not hear the sound, they can release it. The audiometer will then compile an audibility curve based on the changes in the vibration frequency of the vibrating block 4 and the test subject's pressing of button 6, thereby completing a more accurate hearing test. In addition, to facilitate testing with the left and right hands corresponding to the left and right ears, buttons 6 can be provided on both sides of the box 1 for use.

[0021] In one embodiment, the audiometer also includes ear accessories 7 adapted to each of the two ears. Permanent magnets 8 are provided around the perimeter of the cover 3 corresponding to the notch. An attraction block 9, adapted to the permanent magnets 8, is provided on the side of the ear accessory 7 furthest from the ear. This invention can use disposable or easily cleaned and disinfected ear accessories 7. The subject can wear either the left or right ear accessory 7, which fits the cover 3 of the audiometer. By using the attraction block 9 to attach to the permanent magnets 8, the notch of the sound source chamber faces the ear accessory 7, allowing sound to enter the ear while simultaneously isolating external sounds. This allows for bilateral hearing testing using the same instrument. Although the audiometer needs to be relatively close to the body, the isolation provided by the ear accessories 7 reduces the subject's ear contact with the audiometer, minimizing bacterial transmission. Furthermore, the outer side of the cover 3, corresponding to the sound source chamber, is funnel-shaped, recessed into the housing 1. The notch is located at the center of this funnel shape, and the ear accessory 7 is adapted to this funnel shape. The funnel shape allows sound to diffuse after entering the ear accessory 7 through the opening, thus simulating external sounds entering the ear.

[0022] In one embodiment, a gap is left in the middle of the housing 1 to clamp the vibrating plate 5. Connecting rods 10 are respectively provided at the two corners of one end of the housing 1 and in the middle of the other side. The connecting rods 10 pass through the edge of the connecting part 51 to install the vibrating plate 5 into the housing 1. After repeated use, in order to avoid wear and loosening of the vibrating plate 5 and cause audio deviation, the user can open the cover 3 and install the vibrating plate 5 through the internal structure of the housing 1. First, the edge of the connecting part 51 of the vibrating plate 5 is inserted into the gap for positioning, and the opening on the connecting part 51 is adapted to the three connecting rods 10. After the connecting rods 10 pass through, they can fix the relative position of the connecting part 51. At the same time, the connecting rods 10 can also serve as the connection between the housing 1 and the cover 3. The vibration of the vibrating part 52 will drive the connecting part 51, thereby affecting the housing 1. Therefore, in order to prevent some parts from becoming loose during vibration, the end of the connecting rod 10 is tightly fitted with the housing 1 through a soft pad 11, thereby further reducing the impact of the vibration generated by the connecting rod 10 on other parts of the housing 1.

[0023] Furthermore, the cover 3 is connected to the housing 1 via a connector 12. The connector 12 is located at the middle of both sides of the connecting part 51 in the width direction, and the vibrating plate 5 has a through hole with a diameter larger than that of the connector 12. The connector 12 can be a fitting of a plug and a socket, etc., to facilitate the connection and disconnection between the cover 3 and the housing 1. The position of the connector 12 can further position the vibrating plate 5. After the cover 3 is closed, its large through hole will not significantly affect the vibration of the vibrating plate 5, reducing wear. Furthermore, the cover 3 is embedded in one side of the housing 1, so that the housing 1 itself can be easily held by the user with one hand. The other sides of the housing 1 are made of sound-insulating material, so that sound only enters the ear canal through the ear accessory 7 through the notch for testing, minimizing the influence of external and internal sounds on the test.
