Detailed ways

The existing wireless earphones do not have a power management function, so when the user does not use the wireless earphones, the wireless earphones will continue to consume power, resulting in considerable unnecessary power consumption. In contrast, the embodiment of the present invention is equipped with a sensor on the wireless earphone, and the sensor can sense whether the wireless earphone is worn by the user. When the user does not wear the wireless earphone, the operation of the wireless earphone is meaningless, so the wireless earphone can be put into a power saving mode, and even the operation of the wireless earphone can be turned off. In this way, unnecessary power consumption of wireless earphones can be reduced. Embodiments of the present invention will be described in detail below with reference to the accompanying drawings, which illustrate embodiments of the present invention, wherein the same reference numerals indicate the same or similar steps.

Fig. 1 is a schematic diagram of a wireless earphone and a host end according to an embodiment of the present invention; Fig. 2 is a schematic diagram of a device of a wireless earphone according to an embodiment of the present invention; please refer to Fig. 1 and Fig. 2 together, in this embodiment The wireless earphone 10 is described by taking a head-mounted Bluetooth earphone as an example, but the present invention is not limited thereto. In other embodiments, the wireless earphone 10 may also be other types of earphones, such as radio frequency (Radio Frequency) earphones, ear-hook earphones, earbud earphones, or single-ear earphones.

The wireless earphone 10 may include a sensor 30 , a control module 40 , a speaker 50 and a wireless communication module 60 . The control module 40 is coupled to the sensor 30 , the speaker 50 and the wireless communication module 60 . The host end 20 includes a wireless communication module 61 and a host 70 . The host 70 is coupled to the wireless communication module 61 .

The sensor 30 can receive the clock signal CS. In addition, the sensor 30 can be used to sense whether the wireless earphone 10 is worn by the user, and accordingly generate a sensing result SR to the control module 40 . In this embodiment, the sensor 30 is described as a proximity sensor. The sensor 30 can be disposed inside the earcup, for example.

The control module 40 can control various devices of the wireless earphone 10 according to the sensing result SR. For example, the control module 40 can control the switch or volume of the speaker 50 , the switch of the wireless communication module 60 or the operation of the sensor 30 , but the invention is not limited thereto.

The speaker 50 can convert an audio signal (Audio Signal) into a sound recognizable by a user. The wireless communication module 60 can be used to communicate with the wireless communication module 61 of the host terminal 20 . For example, the wireless communication module 60 can be used to receive the audio signal transmitted by the wireless communication module 61 .

The host 70 of the host 20 is, for example, a notebook computer, but the present invention is not limited thereto. In other embodiments, the host 70 can also be other electronic devices, such as mobile phones or music players. The following will be further explained in conjunction with the flow chart,

Fig. 3 is a flow chart of a method for saving power of a wireless earphone according to an embodiment of the present invention. First, in step S301 , the sensor 30 detects whether the wireless earphone 10 is worn by the user, and generates a sensing result SR accordingly. When the sensing result SR indicates that the wireless earphone 10 is not worn by the user, it means that the operation of the wireless earphone 10 is meaningless at this time, so step S302 can be continued, and the control module 40 executes the power saving procedure.

In this embodiment, the power saving procedure is, for example, that the wireless earphone 10 enters the power saving mode, and the control module 40 can reduce the volume of the speaker 50 . In this way, unnecessary power consumption of the wireless earphone 10 can be reduced.

Please note that after the wireless earphone 10 enters the power saving mode, step S301 can be executed again at regular intervals. If the sensing result SR indicates that the wireless earphone 10 is not worn by the user, the wireless earphone 10 will continue to maintain the power saving mode ; If the sensing result SR indicates that the wireless earphone 10 is worn on the user, the step S303 can be continued, and the wireless earphone 10 returns to the normal state, which can reduce the impact of the wireless earphone 10 entering the power saving mode on the user.

It should be noted that although a possible form of the wireless earphone and its power saving method has been described in the above embodiment, those skilled in the art should know that each manufacturer has different designs for the wireless earphone and its power saving method. Likewise, the application of the present invention should not be limited to this possible form. In other words, as long as it detects whether the wireless earphone is worn by the user and decides whether to execute the power saving procedure accordingly, it is already in line with the spirit of the present invention. Several implementations are given below so that those skilled in the art can further understand the spirit of the present invention and implement the present invention.

Those skilled in the art should know that, in the above embodiments, the proximity sensor is only an optional embodiment of the sensor 30 , and the present invention is not limited thereto. In other embodiments, other types of sensors may also be used to sense whether the wireless earphone 10 is worn by the user. For example, the sensor 30 can also be an infrared sensor, which utilizes the infrared blocking principle to sense whether the wireless earphone 10 is worn on the user. For another example, the sensor 30 may also be a capacitive sensor, which utilizes the principle of charge distribution to sense whether the wireless earphone 10 is worn by the user.

The above-mentioned flow chart of FIG. 3 is only an optional embodiment, and the present invention is not limited thereto. Those skilled in the art can change the flowchart of the power saving method according to their requirements. For example, FIG. 4 is a flowchart of a power saving method for a wireless earphone according to an embodiment of the present invention. Please refer to FIG. 1 and FIG. 4 together. Firstly, in step S401 , the sensor 30 senses whether the wireless earphone 10 is worn by the user according to a preset period of the clock signal CS, wherein the preset period is, for example, 30 seconds.

If the sensing result SR indicates that the wireless earphone 10 is not worn by the user, the control module 40 may execute a power saving procedure according to the status of the wireless earphone 10 in step S402 . For example, step S404 may be used to implement a corresponding power saving program according to the specific state of the wireless earphone 10 . On the other hand, if the sensing result SR indicates that the wireless earphone 10 is worn by the user, the control module 40 may control the wireless earphone 10 to return to the normal state at step S403, and return to step S401. A power saving program S404 is provided below for reference by those skilled in the art.

In this embodiment, the state of the wireless earphone 10 is divided into three states, namely the first state, the second state and the third state. In this embodiment, the first state may be the normal state described in step S403. For example, the first state may be that both the speaker 50 and the wireless communication module 60 are activated, and the volume control of the speaker 50 is operated in a user mode (volume set by the user). The second state may be that both the speaker 50 and the wireless communication module 60 are activated, and the volume control operation of the speaker 50 is in the power saving mode (the control module 40 executes the power saving procedure S404 to lower the volume of the speaker 50 ). The third state may be that the speaker 50 is in an off state, and the wireless communication module 60 is in an on state. In this embodiment, the power consumption in the first state is greater than the power consumption in the second state, and the power consumption in the second state is greater than the power consumption in the third state. Dividing the state of the wireless earphone 10 into multiple states can change the state of the wireless earphone 10 in stages, which can not only achieve power saving effect, but also reduce the impact of the power saving process on the user.

Firstly, in step S405, check whether the state of the wireless earphone 10 is the first state, if so, execute step S406, lower the volume of the speaker 50 of the wireless earphone 10, and return to step S401; otherwise, execute step S407.

In step S407, it can be checked whether the state of the wireless earphone 10 is the second state, if so, execute step S408, turn off the speaker 50 of the wireless earphone 10, and return to step S401; otherwise, execute step S409.

In step S409, it can be checked whether the state of the wireless earphone 10 is the third state, and if so, execute step S410 to turn off the wireless communication module 60 of the wireless earphone 10; otherwise, return to step S401.

Please note that during the power-saving program and before the wireless earphone 10 has not completely stopped working, if the sensor 30 senses that the wireless earphone 10 is worn on the user, the wireless earphone 10 can immediately return to the normal state (steps S401, S403 ), which can reduce the impact on the user of the wireless earphone 10 executing the power saving program. In addition, after the wireless earphone 10 stops working completely (eg, step S410 ), the user can restart the wireless earphone 10 to return to the normal state. This can prevent the wireless earphone 10 from consuming a large amount of unnecessary power when the user leaves for a long time.

Those skilled in the art should know that the three states of the wireless earphone 10 listed in this embodiment are just an optional embodiment, and the present invention is not limited thereto. In other embodiments, the wireless earphone 10 may also have a different number of states, and each state may be defined differently. Of course, those skilled in the art can also perform corresponding power saving steps according to the above-mentioned different states.

In addition, although the preset period in this embodiment is described by taking 30 as an example, the present invention is not limited thereto. Those skilled in the art can extend or shorten the above preset period according to their needs. By extending the preset period, the sensor 30 does not need to perform high-frequency sensing, which can reduce the power consumption of the sensor 30 . If the preset period is shortened, the sensor 30 will perform sensing at a higher frequency, which can speed up the response time for the wireless earphone 10 to enter the power-saving state or return to the normal state.

To sum up, the present invention can sense whether the wireless earphone is worn by the user and decide whether to execute the power saving procedure accordingly. Therefore, the power consumption of the wireless earphone can be effectively reduced. In addition, the embodiments of the present invention can save power for the wireless earphones in stages, which can not only reduce the power consumption of the wireless earphones, but also reduce the impact of the power saving program on the user. A better balance between power consumption and response time can be achieved by adjusting the preset sensing period of the sensor.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: it can still be Modifications are made to the technical solutions described in the foregoing embodiments, or equivalent replacements are made to some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
