Description

Technical Field

[0002] Bone conduction is a method of sound conduction, which converts sound into mechanical vibrations of different frequencies, and transmits sound waves through the human skull, bony labyrinth, inner ear lymph, spiral organ, auditory nerve, and auditory center. Compared with the classic sound conduction method of generating sound waves through the diaphragm, bone conduction eliminates many steps of sound wave transmission and can achieve clear sound restoration in noisy environments. Bone conduction technology is divided into bone conduction speaker technology and bone conduction microphone technology. Bone conduction speaker technology is used for receiving calls, which means listening to sounds. Air conduction speakers convert electrical signals into sound waves and transmit them to the auditory nerve.

However, in the existing technology, wearing is usually achieved by relying on the elasticity of the profile of the bone conduction device. The head circumference of users varies, and the pressure of the bone conduction device on the user is single and cannot be adjusted, which greatly reduces the user's wearing experience.

[0019] In order to more clearly illustrate the present invention, the present invention is further described below in conjunction with the accompanying drawings.

[0020] In the following description, the example details are given to provide a deeper understanding of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all embodiments. It should be understood that the specific embodiments are only used to explain the present invention and are not used to limit the present invention.

[0021] It should be understood that when the terms "include" and / or "comprises" are used in this specification, they indicate the existence of the stated features, integers, steps, operations, elements or components, but do not exclude the existence or addition of one or more other features, integers, steps, operations, elements, components or combinations thereof.

[0022] In order to solve the technical problem that the user has no way to reasonably adjust the pressure of the bone transmission device in the prior art, the present application provides a method for adjusting the bone conduction pressure. Figure 1 ,include: Get the pressure range; The actual pressure value of the contact surface is collected to determine whether the pressure value is within the pressure range. If not, the user is prompted to adjust the pressure value within the pressure range according to the first adjustment range, and then to form a use pressure value according to the second adjustment range. If so, the user is directly prompted to form a use pressure value according to the second adjustment range.

[0023] The pressure of the contact surface on the user can be regulated by the first adjustment amplitude and the second adjustment amplitude, so that the user can obtain more flexible and appropriate pressure, and can obtain a more comfortable wearing force while ensuring the appropriate hearing experience of bone conduction.

[0024] In a specific scheme, the value of the first adjustment amplitude is greater than the value of the second adjustment amplitude; it is not difficult to understand that the larger the value of the first adjustment amplitude, the faster the user can adjust within the expected range, and the smaller the value of the second adjustment amplitude, the easier it is for the user to fine-tune the appropriate pressure value for use; in a further scheme, the pressure range is 0.1-5N, and this range has been pointed out in various scientific studies that this pressure range is more suitable for users to use bone conduction devices for a long time.

[0025] The present invention also provides a bone conduction device, see the attached Figure 2 To Attachment Figure 3 , used to perform the above method, comprising a headband 1 body and a bone conduction unit 2, wherein both ends of the headband 1 body are bent in the same direction and connected to the bone conduction unit 2, and a pressure collector is also provided on the contact surface between the bone conduction unit 2 and the user; and further comprising an adjustment device 3, the adjustment device 3 is located between the headband 1 body and the bone conduction unit 2, and the adjustment device 3 adjusts the actual pressure value of the bone conduction unit 2 on the user with a first adjustment amplitude and a second adjustment amplitude to form a use pressure value, and the use pressure value is within a preset pressure range; During use, the user first wears the headband 1 so that the two bone conduction units 2 fit and squeeze on both sides of the user's head. The part where the bone conduction unit 2 fits the head is the contact surface, and the pressure on the contact surface is collected by the pressure collector. The pressure value collected at this time is the actual pressure value. A main control board is also provided in the bone conduction device. The main control board determines whether the actual pressure value is within a preset pressure range. If not, the user is prompted to adjust the actual pressure value within the pressure range by using the adjustment device 3 with a first adjustment amplitude, and then try within the pressure range by using the adjustment device 3 with a second adjustment amplitude, so as to obtain a pressure value that is more suitable for the user as the pressure value for use when wearing.

[0026] It can be seen that the pressure of the contact surface on the user can be regulated by the first adjustment amplitude and the second adjustment amplitude, so that the user can obtain more flexible and appropriate pressure, and can obtain a more comfortable wearing force while ensuring the appropriate hearing experience of bone conduction.

[0027] In this embodiment, the value of the first adjustment amplitude is greater than the value of the second adjustment amplitude; the larger value of the first adjustment amplitude can quickly allow the user to adjust within the expected range, and the smaller value of the second adjustment amplitude can facilitate the user to fine-tune the appropriate pressure value for use. In the specific scheme, the adjustment device 3 is composed of a shell 31, an adjustment gear 32 and an elastic arm 33; the adjustment gear 32 is located in the inner cavity of the shell 31, and one end is formed with an adjustment port 321 on the surface of the shell 31; one end of the elastic arm 33 is meshed with the adjustment gear 32, and the other end protrudes out of one end of the shell 31 and is connected to the bone conduction unit; it is not difficult to understand that the elastic arm 33 is an arc-shaped strip, and the elastic arm 33 can provide a certain elasticity, thereby providing pressure on both sides of the user's head; during use, the user rotates the adjustment gear 32 through the adjustment port 321, and when rotating in the first direction, the elastic arm 33 drives the bone conduction unit 2 to extend. Based on the arc-shaped characteristics of the elastic arm 33, the distance between the two bone conduction units 2 is shortened, thereby increasing the pressure on the user when wearing it. The above-mentioned coordinated adjustment by the elastic arm 33 and the adjustment gear 32 is the aforementioned debugging with the first adjustment range.

[0028] In a more preferred solution, the adjusting gear 32 is a bevel gear, and the edge of the elastic arm 33 is provided with an inclined surface 331 extending to its two ends, and a tooth portion meshing with the bevel gear is arranged on the inclined surface 331; the bevel gear and the tooth portion located on the inclined surface 331 of the elastic arm 33 cooperate with each other, and a larger area can be obtained, which is convenient for the elastic arm 33 to make a protruding movement, so that the debugging work stability is higher; in order to achieve the relative locking of the adjusting gear 32 and the elastic arm 33, the bevel gear surface of the adjusting gear 32 is larger than the inclined surface 331 of the elastic arm 33, and the end of the adjusting gear 32 relative to the adjusting buckle is connected to the inner wall of the shell 31 through an elastic member, and the other inner wall of the shell 31 is provided with a toothed member 35 In the locked state, the adjusting gear 32 is squeezed toward the adjusting port 321 through the elastic member (not shown in the figure), a part of the adjusting gear 32 is meshed with the inclined surface 331 of the elastic arm 33, and the other part is meshed with the latching tooth member 35, so that the adjusting gear 32 and the elastic arm 33 are relatively still, thereby being able to maintain the desired actual pressure; during adjustment, the user uses a tool such as pressing the adjusting port 321 to press the elastic member, and the latching tooth member 35 is separated from the adjusting gear 32. At this time, the adjusting gear 32 continues to be meshed with the inclined surface 331 of the elastic arm 33, and obtains the ability to rotate with the tool. The user rotates the tool to achieve debugging with the above-mentioned first adjustment range.

[0029] In a specific solution, a rubber strip area is further provided on the surface of the elastic arm 33, and a threaded column 34 is further provided at a position on the surface of the shell 31 corresponding to the rubber strip area. One end of the threaded column 34 located in the shell 31 abuts against the rubber strip area (not shown in the figure); it is not difficult to understand that after the actual pressure value quickly falls into the pressure range by adjusting the gear 32 and the elastic arm 33, the abutment force on the elastic arm 33 is changed by changing the screwing depth of the threaded column 34. Due to the change in the abutment force, the extrusion received by the elastic arm 33 will also be different, thereby driving the two bone conduction units 2 to approach each other, thereby adjusting the actual pressure formed by the user and helping the user to use the most appropriate pressure value. The above-mentioned adjustment through the threaded column 34 and the rubber strip area is the aforementioned debugging with the second adjustment range; in a more preferred solution, a plurality of threaded columns 34 are provided, and the abutment forces of the plurality of threaded columns 34 and the rubber strip area are arranged in a gradient order, and the extrusion depths of the plurality of threaded columns 34 are arranged according to a certain gradient, so as to facilitate the user to flexibly adjust the pressure.

[0030] In this embodiment, the vibrator type of the bone conduction unit 2 is one of a moving iron type, a moving coil type or a capacitive type. Based on cost considerations, a moving coil type vibrator is preferably used.

[0031] The advantages of the present invention are: 1. The pressure of the contact surface on the user can be regulated by the first adjustment amplitude and the second adjustment amplitude, so that the user can obtain more flexible and appropriate pressure, and can obtain a more comfortable wearing force while ensuring the appropriate hearing experience of bone conduction.

[0032] 2. The bevel teeth and the teeth on the inclined surface of the elastic arm cooperate with each other to obtain a larger area, which is convenient for the elastic arm to make an extension movement and makes the debugging work more stable.

[0033] The above disclosures are only several specific embodiments of the present invention, but the present invention is not limited thereto, and any changes that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
