Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

In order to make those skilled in the art better understand the solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

A wireless earphone provided by an embodiment of the present invention, as shown in FIGS. 1 to 7 of the specification, includes an elastic earplug cover 1 and an earphone body 2 , and the elastic earplug cover 1 and the earphone body 2 are connected to each other.

The elastic earplug cover 1 is used to be worn in the ear canal. Specifically, when a wireless earphone needs to be worn, the elastic earplug cover 1 is worn in the ear canal. After the elastic earplug cover 1 is squeezed and deformed by the ear canal, the elastic earplug cover 1 The position of the ear canal is fixed. At this time, the elastic earplug 1 and the ear canal can be regarded as interference interference; when there is no need to wear the wireless earphone, the elastic earplug 1 is taken out from the ear canal, and the elastic earplug is removed. 1Return to original shape.

The elastic earplug cover 1 has a magnetic powder layer 11, and the magnetic powder layer 11 can also be deformed by being squeezed by the ear canal. The magnetic powder layer 11 can be regarded as a part of the elastic earplug cover 1, and the elastic earplug cover 1 and the magnetic powder layer 11 can be integrated.

When the wireless earphone needs to be worn, the elastic earplug cover 1 and the magnetic powder layer 11 will be squeezed and deformed by the ear canal, and the positions of the elastic earplug cover 1 and the magnetic powder layer 11 are fixed relative to the ear canal; when the wireless earphone is not required to be worn When the elastic earplug cover 1 is taken out from the ear canal, the elastic earplug cover 1 and the magnetic powder layer 11 after taking out return to the original shape.

The headphone body 2 is provided with a Hall sensor 21 and a control device 22. The output end of the Hall sensor 21 is connected to the control device 22. The magnetic powder layer 11 is located in the sensing area of the Hall sensor 21, that is, the Hall sensor 21 can sense the magnetic powder layer. 11 variants.

Obviously, the Hall sensor 21 should have a sensing area, and the sensing area is the area where the Hall sensor 21 can sense the change of the magnetic field of the magnetic powder layer 11 ; please refer to FIG. (dotted line), the magnetic field of the magnetic powder layer 11 can change the magnetic flux inside the Hall sensor 21, and then the output electrical signal of the Hall sensor 21 will change. After the control device 22 receives different electrical signals, it will execute the corresponding action.

Referring to Figures 4, 6 and 7 of the description, when the elastic earplug cover 1 is not yet worn in the ear canal, that is, when the elastic earplug cover 1 is in its initial shape, the magnetic powder layer 11 is located at the position B in Figure 3 of the specification, At this time, the magnetic flux of the Hall sensor 21 can be recorded as φB. When the elastic earplug cover 1 is worn in the ear canal, the elastic earplug cover 1 and the magnetic powder layer 11 are squeezed and deformed by the ear canal, and the elastic earplug cover 1 and the magnetic powder layer 11 are in the In the dotted line position shown in FIG. 7 of the specification, the magnetic powder layer 11 is located at the position A in FIG. 3 of the specification. At this time, the magnetic flux of the Hall sensor 21 can be recorded as φA; obviously φA>φB.

It can be seen that when the Hall sensor 21 monitors that the magnetic flux increases from φB to φA, and the control device 22 receives the electrical signal that the magnetic flux increases, it can be considered that the elastic earplug cover 1 is worn in the ear canal at this time, and the control device 22 Corresponding action I will be performed; wherein, the corresponding action I performed by the control device 22 includes but is not limited to: turning on the devices such as the speaker 24 and the microphone 25 of the wireless headset, receiving instructions from the mobile phone through the Bluetooth connection link, etc., so that the wireless headset Realize the call function and realize the functions of phone access or dialing, that is, control the wireless headset to open the call function.

When the Hall sensor 21 detects that the magnetic flux decreases from φA to φB, and the control device 22 receives the electrical signal that the magnetic flux decreases, it can be considered that the elastic earplug cover 1 has been taken out from the ear canal at this time, and the control device 22 executes the corresponding Action II; wherein, the corresponding action II performed by the control device 22 includes but is not limited to: turning off the devices such as the speaker 24 and the microphone 25 of the wireless headset, turning off the Bluetooth connection link, etc., so that the wireless headset can turn off the call function and turn off the phone access.

Therefore, the size of the Hall sensor 21 can be set to be small, so as to avoid occupying more space of the sound transmission channel 202 .

In addition, since the space in the cavity 201 is larger than that of the sound transmission channel 202, and in order to avoid affecting the sound transmission effect, the control device 22 is placed in the cavity 201, so that the placement position of the control device 22 is relatively High flexibility.

The hall sensor 21 and the control device 22 can be connected through the flexible circuit board 23. Since the space size of the cavity 201 and the sound transmission channel 202 is small, the flexible characteristics of the flexible circuit board 23 can be used to adapt to different shapes of space, which is helpful to improve the Space utilization rate; in addition, the flexible circuit board 23 can be fitted to the inner wall of the earphone body 2, thereby further reducing the space occupancy rate.

The Hall sensor 21 can be attached to the inner wall of the sound transmission channel 202 by means of gluing or the like. Taking the orientation shown in FIG. 1 of the specification as an example, the left end of the sound transmission channel 202 is connected to the cavity 201, and the right end of the sound transmission channel 202 is connected. For the sound output end, the sound wave is transmitted from left to right, and the Hall sensor 21 can be attached to the inner wall of the sound transmission channel 202, which can minimize the interference of the Hall sensor 21 to the sound wave, so as to ensure that the sound quality is less affected. .

The speaker 24 can be arranged next to the sound transmission channel 202, that is, the control device 22 and the speaker 24 are arranged in the cavity 201, and the sound waves emitted by the speaker 24 can be directly transmitted from the sound transmission channel 202, and do not propagate in the cavity 201, which can further improve the sound quality.

A battery 26 may also be provided in the cavity 201, and the battery 26 is located on the left side of the control device 22, that is, the speaker 24 and the battery 26 are located on two sides of the control device 22, respectively, and a first cable can pass between the control device 22 and the speaker 24. 27 is connected, and the control device 22 and the battery 26 can be connected by a second cable 28 .

The control device 22 , the speaker 24 and the battery 26 can be fixed to the inner wall of the cavity 201 by means of snap-fitting, and certainly can be fixed to the cavity 201 by other means. In addition, the control device 22, the speaker 24 and the battery 26 may be spaced apart, so as to provide a certain installation space and facilitate assembly.

Regarding the setting method of the elastic earplug cover 1 , referring to FIG. 5 of the specification, it can be known that the connecting part 101 and the wearing part 102 connected with the elastic earplug cover 1 can be integrally arranged.

The connection part 101 is used to be sleeved on the outer periphery of the sound transmission channel 202. The shape of the connection part 101 should match the shape of the sound transmission channel 202. As shown in FIG. 1 of the specification, the sound transmission channel 202 101 should also be arranged in a column shape, so that the connecting part 101 and the sound transmission channel 202 are connected.

The wearing part 102 is located on the outer periphery of the connecting part 101, the wearing part 102 is used to be worn in the ear canal, and the magnetic powder layer 11 is arranged on the wearing part 102; obviously, the wearing part 102 and the magnetic powder layer 11 should have elasticity, which can be specifically made of silica gel and magnetic powder. Mixed materials, the connecting portion 101 can be made of a plastic material.

The end of the connecting part 101 facing away from the cavity 201 is connected to the wearing part 102 , the wearing part 102 can be in the shape of an umbrella, and the wearing part 102 gradually expands in the direction facing the cavity 201 , so that the wearing part 102 can smoothly extend into the ear canal.

Regarding the specific shape of the elastic earplug cover 1, as shown in FIG. 8 and FIG. 9 of the specification, the connecting part 101 can be cylindrical. When the connecting part 101 is sleeved on the sound transmission channel 202, the connecting part 101 and the sound transmission channel 202 Relative rotation can occur between them, that is, the elastic earplug cover 1 can rotate around the sound transmission channel 202, and the magnetic powder layer 11 can be evenly distributed on the wearing part 102, so that the magnetic powder layer 11 is located in the sensing range of the Hall sensor 21. In this way, , no matter how the elastic earplug cover 1 rotates relative to the earphone body 2 , the Hall sensor 21 can monitor the deformation of the magnetic powder layer 11 , that is, monitor whether the elastic earplug cover 1 is worn in the ear canal.

As shown in FIG. 9 in the description, the connecting portion 101 can also be set in an elliptical shape, and correspondingly, the sound transmission channel 202 should also be set in an elliptical shape. There is no rotation between the sound transmission channels 202; based on this, the magnetic powder layer 11 can be located at the position of the dotted line on the left in Figure 9 of the specification, and the Hall sensor 21 located in the sound transmission channel 202 should be located in Figure 9 of the specification In this way, since the relative position between the connecting part 101 and the sound transmission channel 202 is fixed, that is, the position of the elastic earplug cover 1 and the earphone body 2 is fixed, the Hall sensor 21 can be ensured. Whether the elastic earplug cover 1 is worn in the ear canal is monitored in real time.

Similar to the setting method of the wireless earphone above, based on the change of the distance between the magnetic powder layer 11 and the Hall device 01, the magnetic flux of the Hall device 01 of the electronic device changes, and then the electronic device can be controlled to perform corresponding functions.

Taking the electronic device as the charging box as an example, the charging box can place two wireless earphones, the charging box is provided with a charging interface 03, and the charging interface 03 is connected to the control board 02. When the wireless earphones are placed in the charging box, the Hall device of the charging box is 01 is affected by the magnetic powder layer 11 of the wireless headset, the magnetic flux of the Hall device 01 becomes larger, the control board 02 can control the charging interface 03 to charge the wireless headset, and of course, the control board 02 can also control the light-emitting part 04 to flash to indicate this When the wireless earphone is charging; when the wireless earphone is taken out of the charging box, the magnetic flux of the Hall device 01 becomes smaller, and the control board 02 controls the charging interface 03 to stop discharging, and also controls the light-emitting component 04 to turn off.

The charging box can also be provided with an energy storage part 05 , the energy storage part 05 is connected to the control board 02 , and the energy storage part 05 provides electrical energy to the charging interface 03 .

The electronic device herein can also be a wearable device with wireless earphones, etc. When the control board 02 learns that the wireless earphone is worn in the ear canal through the magnetic flux change of the Hall device 01, the control board 02 can control the wearable device to perform the first action; And when the control board 02 learns that the wireless earphone is not worn in the ear canal, the control board 02 controls the wearable device to perform the second action. The first action and the second action can be set according to different wearable devices, which will not be detailed here. The in-situ detection method for a wireless earphone provided by the embodiment of the present invention is applied to the wireless earphone provided with the elastic earplug cover 1 described above, and in combination with the wireless earphone and the electronic device described above, the in-situ detection method for the wireless earphone includes: :

acquiring the first magnetic flux of the Hall sensor 21 disposed in the wireless earphone and used to sense the magnetism at the magnetic powder layer 11 of the elastic earplug sleeve 1;

If the first magnetic flux is greater than or equal to the first trigger value, it indicates that the elastic earplug cover 1 is greatly deformed. At this time, the elastic earplug cover 1 is worn in the ear canal. At this time, the control device 22 can perform the above corresponding action I, that is, Control the wireless headset to turn on the call function.

If the first magnetic flux is smaller than the first trigger value, it indicates that the elastic earplug cover 1 has not undergone a large deformation, and the elastic earplug cover 1 is not worn in the ear canal at this time, and the control device 22 can perform the above-mentioned corresponding action II at this time, That is to control the wireless headset to turn off the call function.

In this paper, the Hall device 01 is set in the charging box as an example. Since the wireless earphone is usually placed in the charging box, before performing the above steps, it is also possible to first detect whether the wireless earphone is taken out of the charging box.

acquiring the second magnetic flux of the Hall device 01 disposed outside the wireless earphone and used to sense the magnetic properties at the magnetic powder layer 11 of the elastic earplug sleeve 1;

Obviously, the Hall device 01 should be installed in the charging box and located outside the wireless earphone; if the second magnetic flux is greater than or equal to the second trigger value, it means that the elastic earplug sleeve 1 has been elastically deformed, and the wireless earphone is placed in the charging box. When the wireless headset is directly controlled to be in a low power consumption mode, the wireless headset can also be charged.

If the second magnetic flux is smaller than the second trigger value, it is necessary to further determine the relationship between the first magnetic flux obtained by the Hall sensor 21 and the first trigger value.

In the above, since the positions of the Hall sensor 21 and the Hall device 01 are different, the magnitudes of the first magnetic flux and the second magnetic flux are different for the deformation of the elastic earplug cover 1, so the first trigger value and the second trigger value are different. The specific value should also be determined according to actual needs, and this article will not expand.

It should be noted that in this specification, relational terms such as first and second are only used to distinguish one entity from several other entities, and do not necessarily require or imply the existence of any such entity between these entities The actual relationship or sequence.
