[0018] In order to more clearly describe the present application, the present application will be further described below in combination with the drawings.

[0019] In the following description, the example details are given in order to provide a more in-depth understanding of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, not all the embodiments. It should be understood that the specific embodiments are only used to explain the present application, and are not used to limit the present application.

[0020] It should be understood that when the terms "comprise" and / or "include" are used in the specification, they are taken to specify the presence of stated features, integers, steps, operations, elements, or components but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, or groups thereof.

[0021] In order to solve the technical problem that the user has no way to reasonably adjust the pressure of the bone conduction device in the prior art, the application provides a head-mounted bone conduction earphone, which comprises a connecting piece and two vibrator units. The two ends of the connecting piece are bent and connected with the vibrator units to form a connecting piece with the contour of the brain, and a spacing for wearing is formed between the two vibrator units. An adjusting device is arranged between the connecting piece and the vibrator units, and the adjusting device is used to adjust the relative spacing between the two vibrator units. By adjusting the spacing between the two vibrator units through the adjusting device, the user can seek a suitable pressure parameter as the use pressure when wearing, so as to prevent the occurrence of an inappropriate size and a poor wearing experience.

[0022] Further illustrated in combination with the actual situation, in the process of use, the user first wears the connecting piece 1, so that the two vibrator units 2 are attached and pressed on both sides of the user's head. The attachment part of the vibrator unit 2 to the head is the contact surface, and a pressure collector is arranged in the vibrator unit. The pressure of the contact surface is collected through the pressure collector. At this time, the collected pressure value is the actual pressure value. The main control board in the bone conduction unit judges whether the actual pressure value is within the preset pressure range. If not, the user is prompted to adjust the actual pressure value to the pressure range through the adjusting device 3 with a first adjusting amplitude, and then try within the pressure range through the adjusting device 3 with a second adjusting amplitude, so as to obtain a more suitable pressure value for the user as the use pressure value when wearing.

[0023] It can be seen that the first adjusting amplitude and the second adjusting amplitude are used to adjust the pressure of the contact surface on the user, so that the user can obtain more flexible and suitable pressure, and can obtain a more comfortable wearing force while ensuring that the hearing feeling of bone conduction is suitable.

[0024] More specifically, the pressure range is 0.1-5N, which is indicated by various scientific researches. This pressure range is more suitable for the user to use the bone conduction device for a long time. The value of the first adjusting amplitude is greater than the value of the second adjusting amplitude. The value of the first adjusting amplitude is greater, which can quickly adjust the user to the expected range. The value of the second adjusting amplitude is smaller, which can facilitate the user to fine-tune the suitable pressure value for use.

[0025] In a specific solution, the adjusting device 3 is composed of a shell 31, an adjusting gear 32 and an elastic arm 33; the adjusting gear 32 is located in the inner cavity formed by the shell 31, and one end of the adjusting gear 32 is provided with an adjusting port 321 on the surface of the shell 31; one end of the elastic arm 33 is engaged with the adjusting gear 32, and the other end of the elastic arm 33 is connected with the vibrator unit 2 and protrudes from one end of the shell 31; 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 and thus provide pressure on both sides of the user's head; during use, the user rotates the adjusting gear 32 through the adjusting port 321, and when rotating in the first direction, the elastic arm 33 drives the vibrator unit 2 to protrude, and based on the arc-shaped characteristic of the elastic arm 33, the distance between the two vibrator units 2 is shortened, and thus the pressure on the user when wearing can be improved; the above adjustment by the elastic arm 33 and the adjusting gear 32 is the aforementioned adjustment with the first adjustment range.

[0026] In a more preferred solution, the adjusting gear 32 is a bevel gear, and the edge of the elastic arm 33 is provided with a slope 331 extending to both ends, and the slope 331 is provided with a tooth portion engaged with the bevel gear; the bevel gear and the tooth portion on the slope 331 of the elastic arm 33 cooperate with each other to obtain a larger area, which facilitates the protruding movement of the elastic arm 33 and makes the adjustment work more stable; in order to realize 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 slope 331 of the elastic arm 33, one end of the adjusting gear 32 is connected with the inner side wall of the shell 31 through an elastic member, and the other inner side wall of the shell 31 is provided with a clamping member 35; in the locked state, the adjusting gear 32 is pressed towards the adjusting port 321 through the elastic member (not shown in the figure), a part of the adjusting gear 32 is engaged with the slope 331 of the elastic arm 33, and the other part is clamped with the clamping member 35, realizing the relative static state of the adjusting gear 32 and the elastic arm 33, and thus the desired actual pressure can be maintained; when adjusting, the user presses the adjusting port 321 by means of a tool, so that the elastic member is pressed, the clamping member 35 is separated from the adjusting gear 32, the adjusting gear 32 continues to engage with the slope 331 of the elastic arm 33 at this time, and obtains the ability to rotate with the tool, and the user rotates the tool to adjust with the above-mentioned first adjustment range.

[0027] In a specific scheme, the surface of the elastic arm 33 is further provided with a rubber strip area, the surface of the shell 31 is further provided with a threaded column 34 corresponding to the position of the rubber strip area, and 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 is quickly brought into the pressure range through the cooperation of the gear 32 and the elastic arm 33, the depth of the threaded column 34 is changed to change the abutting force of the elastic arm 33. Due to the change of the abutting force, the extrusion of the elastic arm 33 is also different, thereby driving the two vibrator units 2 to approach each other, achieving the adjustment of the actual pressure formed by the user, helping the user to use the most suitable pressure value. The above cooperation and adjustment of the threaded column 34 and the rubber strip area are the aforementioned adjustment with the second adjustment range. In a more preferred scheme, the threaded column 34 is provided with a plurality of threaded columns, the abutting 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.

[0028] In the embodiment, the vibrator type of the vibrator unit 2 is one of a moving iron type, a moving coil type or a capacitor type; and the moving coil type is preferred in consideration of cost.

[0029] The advantages of the utility model lie in:

[0030] The distance between the two vibrator units is adjusted by the adjusting device, so that the user can seek a suitable pressure parameter as the use pressure when wearing, and prevent the size from being unsuitable and the wearing experience from being poor.

[0031] The above disclosure is only a few specific embodiments of the utility model, but the utility model is not limited to this, and any changes that can be thought of by those skilled in the art should fall within the protection scope of the utility model.
