As shown in fig. 1 and 2, the control cabin according to a preferred embodiment of the present invention includes a housing 1, a main control board 2, and a flexible circuit board 3.

The housing 1 has an accommodating cavity 1a, and the main control board 2 and the flexible circuit board 3 are both disposed in the accommodating cavity 1a. The control cabin further comprises a cover body 7 for sealing the containing cavity 1a of the shell 1. The housing 1 is provided with a panel 10, in this embodiment, the panel 10 is a separate component from the housing 1 and is connected to the housing 1, and in other embodiments, the panel 10 may be integrally injection molded with the housing 1 and is a part of the housing 1.

It is understood that the projection of the flexible circuit board 3 to the side of the panel 10 is at least partially located on the panel 10, so that a touch to the panel 10 can be sensed by the flexible circuit board 3, and the schematic position of the flexible circuit board 3 is shown in a dotted line in fig. 1, and it is obvious that the larger the area of the panel 1 covered by the flexible circuit board 3 is, the larger the sensing area of the touch is, and the greater the sensitivity of the touch is.

In a preferred embodiment, the touch sensors are capacitive sensors, and the number of the capacitive sensors is multiple, and the capacitive sensors are arranged on the flexible circuit board 3 at intervals, and may be distributed in an array, for example. Therefore, when the finger draws a gesture on the panel 10, capacitance changes occur in the capacitive sensors at different positions, different gestures can be determined according to the sequence and the strength of sensing signals generated by the capacitive sensors at different positions, and then a control instruction corresponding to the gesture is calculated. For example, a control command to increase the volume may be generated when sliding up on the control panel 10, whereas a control command to decrease the volume may be generated when sliding down on the control panel 10.

Like this, draw the gesture through touch panel 10 (for example click) or draw on panel 10 and be controllable bone conduction earphone or other electronic equipment promptly, it is very convenient to operate, and the casing 1 volume of control chamber is great, can set up the flexible circuit board 3 and the panel 10 of bigger area for the touch area is bigger, has strengthened the perception ability to the gesture, is difficult for the maloperation, uses also more comfortablely.

It can be understood that, the closer the panel 10 is to the flexible circuit board 3, the more sensitive the touch sensor is to the sensing of the finger touch panel 10, as shown in fig. 3 and 4, in order to reduce the distance between the panel 10 and the flexible circuit board 3, the inner wall of the housing 1 is provided with a first positioning groove 13, the flexible circuit board 3 is arranged in the first positioning groove 13, and the flexible circuit board is attached to the bottom surface of the first positioning groove 13, for example, can be fixed in the first positioning groove 13 by an adhesive method. The first positioning groove 13 not only can reduce the wall thickness of the housing 1 and reduce the distance between the panel 10 and the flexible circuit board 3, but also can position the flexible circuit board 3.

Further, as shown in fig. 5 and 6, the outer surface of the housing 1 is provided with a second positioning slot 11, and the panel 10 is installed in the second positioning slot 11 and can be connected to the housing 1 by gluing, for example. By providing the second positioning groove 11, the distance between the panel 10 and the flexible circuit board 3 can be further shortened, and the sensitivity of the touch sensor can be improved.

The panel 10 is provided with a light-transmitting portion 100, one possible shape of the light-transmitting portion 100 being shown in dashed lines in fig. 7. In a preferred embodiment, the panel 10 is made of a transparent material, such as PC or PMMA with high light transmittance, and the panel 10 is coated with an opaque material, and the portion uncovered by the opaque material forms the light-transmitting portion 100. The main control panel 2 includes a light source 20 disposed corresponding to the light transmission portion 100, and the light source 20 is preferably an LED lamp bead, and can emit light under the control of the main control panel 2, and when the light source 20 emits light, it can illuminate the light transmission portion 100, so that a person can observe the illuminated light transmission portion 100. The light-transmitting portion 100 may be, for example, text or pattern information such as a brand name and a logo, which can enhance the aesthetic appearance of the product, or may be used as an indicator light, which gives a different indication to the user by information such as a color and/or a blinking frequency.

It is understood that there may be one or more light sources 20, and when the length or width dimension of the light-transmitting portion 100 is large, the number of light sources 20 may be increased adaptively, so as to illuminate the light-transmitting portion 100 reliably.

In order to enable the light of the light source 20 to be reliably transmitted to the light-transmitting portion 100, the flexible circuit board 3 is provided with an avoiding hole 31 corresponding to the light source 20, the housing 1 is provided with a through hole 12 corresponding to the light source 20, and the outlines of the avoiding hole 31 and the through hole 12 are all around the outside of the light-transmitting portion 100 to prevent the flexible circuit board 3 and the housing 1 from shielding the light. Light emitted from the light source 20 is irradiated to the light-transmitting portion 100 through the through hole 12 and the escape hole 31, so that the light-transmitting portion 100 emits light.

In addition to the light guide 4 to increase the uniformity of the emitted light from the light transmission part 100, the light diffusion film 6 may be provided to increase the uniformity of the emitted light from the light transmission part 100. As shown in fig. 10, the light diffusion film 6 is located between the panel 10 and the housing 1, is disposed opposite to the panel 10, and at least covers the light transmission portion 100, so that when light enters the light diffusion film 6, refraction, reflection and scattering phenomena can occur in the film, and the light can be corrected into a uniform surface light source to achieve an optical diffusion effect, thereby making the brightness of the light transmission portion 100 more uniform. As shown in fig. 11 and 12, the casing 1 is provided with a third positioning groove 15 on the groove bottom surface of the second positioning groove 11, and the light diffusion film 6 is installed in the third positioning groove 15, and may be connected to the groove bottom surface of the third positioning groove 15 by, for example, adhesive.

It will be appreciated that the control cabin may be provided with both the light guide 4 and the light diffusing film 6. Preferably, when the light guide bar 4 and the light diffusion film 6 are disposed at the same time, the light guide bar 4 is made of a material with high light transmittance, such as PC or PMMA, and the like, and no light scattering agent is added to reduce the loss of light after the light is transmitted through the light guide bar 4.

As shown in fig. 8 and 13, the control cabin further includes a light-shielding ring 5 located between the casing 1 and the main control panel 2, the light-shielding ring 5 surrounds the outside of the light source 20, so that light leakage of the light source 20 can be reduced, and light leakage is prevented, and thus, even if a gap is formed at a joint between the casing 1 and the cover 7, a bad phenomenon of light leakage does not occur. Referring to fig. 14, in the present embodiment, one end of the light shielding ring 5 is adhered to the end of the ring portion 14, and the other end abuts against the main control board 2. In other embodiments, the light-shielding ring 5 may be wound around the outside of the ring portion 14 at one end and abutted against the main control board 2 at the other end, and in embodiments where the ring portion 14 is not provided, the light-shielding ring 5 may be directly abutted against the inner wall of the housing 1. The shading ring 5 is made of flexible materials, for example, the shading ring can be made of foam, sponge and the like, and a plurality of electronic elements are arranged on the main control board 2, so that the electronic elements are not easily crushed by the shading ring 5 made of the flexible materials, and the shading effect is ensured by filling the gaps among the electronic elements with adaptive deformation.
