Description

Technical Field

[0001] This utility model relates to the field of audiometer headphones, and more specifically, to an audiometer headphone with automatically adjustable tension. Background Technology

[0002] Audiometer headphones are devices used to transmit sound stimuli to test subjects during hearing tests. The tension of the same audiometer headphone varies when worn by people with different head circumferences. However, there are requirements for the tension of the audiometer headphone after it is opened during hearing tests. But how to conveniently adjust the tension of the audiometer headphone is a technical problem that has been troubling people.

[0003] Currently, when adjusting the tension of an audiometer earphone, as disclosed in Chinese patent CN104902374A, the earphone tension adjustment mechanism is controlled manually by a linkage to adjust the tension. However, manual control is not quick or convenient.

[0004] Therefore, it is necessary to propose an audiometer earphone with automatic tension adjustment to solve the above problems. Utility Model Content

[0005] To overcome at least one of the defects (deficiencies) of the prior art described above, this utility model provides an audiometer earphone with automatically adjustable tension.

[0006] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows: an audiometer earphone with automatic tension adjustment, comprising an elastic plate and two symmetrically arranged earphone covers;

[0007] The earphone cover is equipped with an electric push rod and a connecting bracket, and the connecting bracket is rotatably mounted on the earphone cover;

[0008] The elastic plate passes through the gap between the connecting frame and the earphone cover on both sides and is then fitted onto the electric push rod. By setting electric push rods on both sides of the earphone cover, the tension of the elastic plate can be adjusted by simply controlling the electric push rods remotely when it is necessary to adjust the tension of the elastic plate. This makes it suitable for users with different head sizes, allowing the audiometer inside the earphone cover to better measure the data inside the human ear canal. In addition, the setting of the connecting frame can distribute the stress position of the elastic plate to a certain extent, which can effectively extend the service life of the elastic plate.

[0009] Furthermore, the electric actuator includes a actuator, a drive motor, an actuator gear, a first baffle, a second baffle, and an actuator seat mounted on the headphone cover;

[0010] The drive motor is mounted on the push rod seat, and the drive motor is connected to the push rod through the push rod gear;

[0011] A push rod sleeve is fitted on the outside of the push rod. The first and second baffles are both set on the push rod sleeve. The elastic plate is fitted between the first and second baffles. When it is necessary to control the movement of the push motor, the push motor can be controlled to rotate by remote control. The push motor drives the push rod gear to rotate, so that the push rod on the push rod gear rotates. Therefore, the push rod sleeve fitted on the push rod can drive the elastic plate to move on the push rod sleeve, thereby adjusting the tension of the audiometer earphone.

[0012] Furthermore, a protective sleeve is provided on the outer side of the elastic plate, which can protect the elastic plate.

[0013] Furthermore, a first pressure sensor is provided on the top of the elastic plate, which allows for the rapid detection of the pressure value at the top of the elastic plate.

[0014] Furthermore, a second pressure sensor is provided on both sides of the elastic plate. By setting the second pressure sensor, the pressure value on both sides of the elastic plate can be detected quickly.

[0015] Furthermore, the connecting frame is arc-shaped. In practical applications, the connecting frame can also take other shapes, all of which are within the protection scope of this utility model.

[0016] Furthermore, the earphone cover is equipped with an earphone connection cable, which facilitates the earphones inside the earphone cover to receive sound.

[0017] Compared with the prior art, the beneficial effects of this utility model's technical solution are:

[0018] The present invention discloses an audiometer earphone with automatic tension adjustment.

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.

[0025] like Figure 1 As shown, an audiometer earphone with automatic tension adjustment includes an elastic plate 1 and two symmetrically arranged earphone covers 2. The earphone covers are equipped with electric push rods 3 and connecting brackets 4, with the connecting brackets rotatably mounted on the earphone covers. The elastic plate passes through gaps 5 between the connecting brackets and the earphone covers on both sides and is fitted onto the electric push rods. By setting electric push rods on both sides of the earphone covers, when the tension of the elastic plate needs to be adjusted, the tension can be adjusted simply by remotely controlling the electric push rods. This makes it suitable for users with different head sizes, allowing the audiometer inside the earphone covers to better measure data within the human ear canal. Furthermore, the connecting brackets can distribute the stress on the elastic plate to a certain extent, effectively extending the service life of the elastic plate.

The push motor is mounted on the push rod seat and connected to the push rod via the push rod gear. A push rod sleeve 12 is fitted on the outside of the push rod. The first and second baffles are both mounted on the push rod sleeve, and an elastic plate is fitted between the first and second baffles. When it is necessary to control the movement of the push motor, the push motor can be controlled to rotate via remote control. The push motor drives the push rod gear to rotate, causing the push rod on the push rod gear to rotate. Therefore, the push rod sleeve fitted on the push rod can drive the elastic plate to move on the push rod sleeve, thereby adjusting the tension of the audiometer earphone. In this utility model, a protective sleeve 13 is provided on the outside of the elastic plate to protect the elastic plate.

[0027] In this invention, a first pressure sensor 14 is provided on the top of the elastic plate. The pressure value at the top of the elastic plate can be quickly detected by the first pressure sensor. Second pressure sensors 15 are provided on both sides of the elastic plate. The pressure values ​​on both sides of the elastic plate can be quickly detected by the second pressure sensors. In this invention, the connecting frame is arc-shaped. In practical applications, the connecting frame can also take other shapes, all of which are within the protection scope of this invention. The headphone cover is provided with a headphone connecting cable 16. The headphone connecting cable facilitates the earphones inside the headphone cover to receive sound.

[0028] Example

[0029] In this embodiment, when it is necessary to adjust the tension of the elastic plate, the motor can be controlled to rotate via remote control. The motor drives the push rod gear to rotate, causing the push rod on the push rod gear to rotate. Therefore, the push rod sleeve fitted on the push rod can drive the elastic plate to move on the push rod sleeve, thereby adjusting the tension of the audiometer earphone and making it suitable for users with different head sizes. This allows the audiometer inside the earphone to better measure the data inside the human ear canal. In addition, the setting of the connecting bracket can distribute the force position of the elastic plate to a certain extent, which can effectively extend the service life of the elastic plate.
