Description
Technical Field
The present application relates to the field of electronic devices and wireless communication technologies, and in particular, to a method and an apparatus for reducing interference to a speaker, and an electronic device.
Background
With the social progress and the improvement of the living standard of people, many portable electronic devices, such as mobile phones, tablet computers, various wearable devices, etc., have become essential living goods for people. Some of these electronic devices have a speaker, such as a mobile phone, a wireless headset, etc., which is usually a passive device and is susceptible to electromagnetic interference, so as to emit interference noise such as "sand" and "buzz".
In the implementation of the solution of the present application, the inventor finds that one of the sources of electromagnetic interference to the speaker of the electronic device comes from the battery in the electronic device. On one hand, because many electronic devices are small in size, the battery is close to the speaker, and on the other hand, once the power consumption of the electronic device fluctuates, for example, the power of the electronic device is sometimes high and sometimes low in a certain period of time due to wireless transmission or other reasons, the output voltage or current of the battery may also fluctuate, which causes electromagnetic radiation, and thus interferes with the speaker.
Take wireless transmission as an example: many electronic devices have a wireless module, for example, the wireless module may be one or more of bluetooth (such as classical bluetooth, bluetooth low energy, LE audio, etc.), WiFi, ZigBee, and mobile communication systems (2G, 3G, 4G, 5G, and 6G), and the wireless module is usually TDD, that is, time division, and in short, when wirelessly transmitting, the wireless module has the characteristics of transmitting for a period of time and not transmitting for a period of time. The power consumption during wireless transmission is much larger than that during non-transmission, and even if the power consumption of a wireless receiving module, a processor module and the like is smaller and smaller along with the progress of the process, the power during wireless transmission is still larger due to the requirements of various related wireless protocol transmission power. Just because the power consumption when the wireless module of electronic equipment is transmitted wirelessly is much greater than when not transmitting, so the electric current that comes from the battery when wireless transmission is also much bigger, cause the battery output current to change when wireless transmission and not transmitting, or because the existence of battery internal resistance makes battery output voltage change when wireless transmission and not transmitting, and the electric current of battery or voltage change can cause electromagnetic radiation, the interference speaker, make it send out interference sound such as "sand and sand", "buzz".

in step S101, it is determined whether the electronic device enters a designated mode, where the designated mode includes a first state and a second state, and power consumption of the electronic device in the first state is greater than power consumption of the electronic device in the second state.
In step S102, if the electronic device enters the designated mode, when the electronic device is in the second state, a preset policy is executed to make the actual power consumption of the electronic device in the second state reach or approach the power consumption of the electronic device in the first state.
As an example, the electronic device may be a wireless headset. Further, the wireless headset may specifically be a true wireless stereo TWS headset, for example.
TWS is an abbreviation of True Wireless Stereo, True radio Stereo. The TWS technology is developed on the basis of the Bluetooth technology. The TWS earphone comprises a pair of wireless earphones, one of the wireless earphones is a main earphone, the other wireless earphone is a secondary earphone, the mobile phone is connected with the main earphone in a wireless mode, the main earphone is connected with the secondary earphone in a wireless mode, and real Bluetooth left and right sound channel wireless separation use is achieved.
The embodiment is not limited to specific contents of the specific mode, the first state and the second state, and those skilled in the art may select and design according to different requirements/different scenarios, and these selections and designs may be used herein without departing from the spirit and scope of the present application.
As an example, in this embodiment or some other embodiments of the present application, the electronic device may include a wireless module, the specified mode includes a process of establishing and/or being in a wireless connection, the first state includes a state in which specified information is wirelessly transmitted in the process, and the second state includes a state in which the specified information is not wirelessly transmitted in the process.
As to the wireless communication technology related to the embodiments of the present application, the present application is not limited, and any communication standard or protocol may be used, for example, but not limited to, GSM (Global System for Mobile communication), GPRS (general packet Radio Service), CDMA2000(Code Division Multiple Access2000 ), WCDMA (Wideband Code Division Multiple Access, TD), Time Division-Synchronous Code Division Multiple Access (Time Division-Synchronous Code Division Multiple Access), FDD-LTE (Frequency Division-Long Term duplex Evolution, Frequency Division-Long Term Evolution), TDD-LTE (Time Division-Long Term Evolution, and the like.
The process in the wireless connection and the specific content of the specific information are not limited in this embodiment, and those skilled in the art may select and design themselves according to different needs/different scenarios, and these choices and designs may be used herein without departing from the spirit and scope of the present application.
As an example, in this embodiment or some other embodiments of the present application, the wireless module may include a bluetooth module, the establishing of the wireless connection includes initiating a bluetooth backhaul connection, the first state includes a state in which an ID packet is transmitted during initiating the bluetooth backhaul connection, and the second state includes a state in which the ID packet is not transmitted during initiating the bluetooth backhaul connection.
For example, in some other embodiments, the electronic device may have a USB interface, the designated mode may be a mode when the USB is in operation (for example, the electronic device is connected to a computer through the USB), the first state may be a USB data transceiving state in which power consumption is high, and the second state may be a state in which the USB does not transceive data in the mode in which power consumption is lower than that in transceiving data.
It should be noted that, in the embodiment of the present application, when the specified mode exits or ends, for example, the bluetooth connection is completed or the USB connection is disconnected, the method will not be executed any more, and after entering the specified mode again, the method is executed again. Because this application scheme can additionally consume the electric quantity of some batteries more, so this application scheme prescribes to the executive condition in appointed mode, just launches under the mode that the interference is comparatively serious and time is shorter the method to avoid the excessive consumption of battery electric quantity, realized losing balance between the consumption and avoiding speaker interference, richened the product function, promoted user experience.
The specific content of the preset policy, that is, what kind of preset policy is specifically executed to enable the actual power consumption of the electronic device in the second state to reach or approach the power consumption in the first state, is not limited in this embodiment, and those skilled in the art may select and design the preset policy according to different needs/different scenarios, and these choices and designs that may be used herein do not depart from the spirit and scope of the present application.
It is easy to understand that, in some cases, the actual power consumption in the second state can be increased to a level equal to the power consumption in the first state through precise power consumption control, and in other cases, the actual power consumption in the second state can be close to the power consumption in the first state, and this embodiment does not need to quantify or limit the specific degree of the proximity, and those skilled in the art can design according to specific scenarios and requirements as long as the power consumption becomes relatively smooth and the speaker is not interfered or is less interfered.
For a specific preset strategy, some examples are given below:
in this embodiment or some other embodiments of the present application, the electronic device may include a switchable redundant resistor and/or a switchable redundant hardware circuit, and the preset strategy may include:
when in the second state, the redundant resistor and/or the redundant hardware circuit are used to increase the power consumption of the electronic device.
For example, the battery of the electronic device may be connected to the Vbat pin, and the resistor is internal to a chip of the electronic device, connected to Vbat.
The chip includes, for example, a wireless module, an audio module, a processor, and the like. The chip has a Vbat pin.
Specifically, taking an electronic device with a time division wireless transmission module as an example, a resistor with a switch may be added as a redundant resistor, and in a non-transmission stage of the time division wireless transmission module, the switch is turned on to make the resistor consume battery power. The resistor is selected to consume power equal to or close to power consumption 1-power consumption 2, wherein power consumption 1 is power consumption in the first state, and power consumption 2 is power consumption when a preset strategy is not executed in the second state. The resistor may operate at Vbat. The battery is connected to the Vbat pin and the resistor is internal to the chip, connected below Vbat. In another embodiment, the resistor may operate at other voltages as well, as long as the resistor is selected to consume power at or near power consumption 1-2.
In another embodiment, operational circuitry, which may be redundant hardware circuitry, may be added to consume power at or near power consumption 1-2.
In this embodiment or some other embodiments of the present application, the preset policy may include:
when the electronic device is in the second state, the circuit which does not work originally in the current state is used to increase the power consumption of the electronic device, and/or all circuits or part circuits of a chip of the electronic device are enabled to work at higher voltage to increase the power consumption of the electronic device.
In a second state, for example, in a non-operating stage of the wireless transmission module, a part of circuits that are not otherwise operating, for example, a part of circuits of the wireless transmission module, may be operated to increase power consumption. Similarly, if the wireless receiving stage is not currently in use, a part of the wireless receiving circuit which is not originally in use can be operated to increase power consumption.
In this embodiment or some other embodiments of the present application, the preset policy may include:
when the electronic equipment is in the second state, the work load of a chip processor of the electronic equipment is increased, and/or the processor works at a higher clock frequency to increase the power consumption of the electronic equipment.
For example, the processor may be caused to repeatedly read certain memory data to increase power consumption.
In the embodiment of the application, after an electronic device (e.g., a wireless headset) enters some specified modes (e.g., bluetooth loopback) which are susceptible to interference, even if power consumption fluctuation occurs due to some reasons (e.g., wireless transmission), the power consumption can be weakened, counteracted or leveled by dynamically adjusting the power consumption, so that the power consumption becomes relatively stable, thereby avoiding current or voltage fluctuation of a battery, avoiding or reducing generation of electromagnetic radiation, further preventing or reducing interference on a speaker in the specified mode, enhancing the anti-interference capability of the speaker, and improving user experience.
The following takes the TWS headset as an example, and further describes the solution of the present application in combination with a specific application scenario that the TWS headset and a terminal (e.g., a mobile phone) are connected back. Of course, the following application scenarios are only exemplary, and in practical applications, the application scenarios may also be applied to other application scenarios.
Bluetooth is a wireless communication technology, and can implement wireless connection between two devices within a certain distance range. Once the distance between two devices exceeds the maximum distance supported by bluetooth technology or is blocked or interfered with, the connection between the two devices is broken. When the distance between two devices is less than the maximum distance supported by bluetooth technology or when channel conditions become good, the two devices that have been previously connected may be reconnected, and this process of reconnection may be referred to as bluetooth reconnection.
Referring to fig. 3, in fig. 3, 301 is a main earphone, 302 is a sub-earphone, 301 and 302 form a pair of TWS earphones, and 303 is a terminal (e.g., a handset) connected to the main earphone.
When the TWS headset is disconnected from the connected terminal, the connection may be re-made. For example, when the TWS headset is out of the box (removed from the charging box), a reconnect operation may be triggered. Or may trigger a loopback operation when the TWS headset is worn on the ear.
In the reconnection process, when a main earphone in the TWS earphone performs reconnection operation with the terminal, the main earphone needs to send an ID packet to the terminal, and the terminal receives and responds to the ID packet, and finally completes reconnection. When the main earphone transmits an ID packet, since the transmission power is large, power consumption becomes large, and battery current or voltage is likely to fluctuate to cause interference with an earphone speaker.
Fig. 2 shows a schematic structure of a bluetooth frame of a physical layer. Packet format of basic rate as shown in fig. 2, a bluetooth frame of a physical layer includes 3 fields, in a direction from least significant bit to most significant bit, an access code 201, a header 202, and a payload 203, respectively, where: access code 201 is a flag for picoet, used for timing synchronization, offset compensation, paging, and inquiry; the packet header 202 contains information for bluetooth link control; the payload 203 carries useful information, which may be, for example, bluetooth audio data.
The master earphone sends an ID packet to the terminal, which may only comprise an access code, so that the ID packet has a duration of 72us for classical Bluetooth; and may also include an access code and a header, the ID packet duration is 126 us.
The bluetooth slot is 625 us. When connecting back, the main earphone sends ID packets to the terminal, and sends one ID packet every 625us/2, namely, two ID packets are sent in one time slot. When the master earphone sends the ID packet, the power consumption is relatively large because the transmission power is relatively large. The ID packet has a short duration (e.g., 72us), so that the ID packet is not sent most of the time during the loopback process. In the process of the main earphone being connected back, the power consumed by the battery is large during the period of sending the ID packet, and the fluctuation can interfere with the loudspeaker through electromagnetic radiation and generate noise when the sending interval is small. Further, since the sending duration of the ID packet is long during the loopback, from the second level to several tens of seconds, the interval for sending the ID packet is short, and one ID packet is sent every 625us/2, the speaker is seriously disturbed, and audio noise is generated. Therefore, under the scene, the scheme of the application can be applied, namely, the power consumption of the Bluetooth non-emission stage is compensated during the loop connection, so that the power consumption of the emission stage and the power consumption of the non-emission stage during the loop connection are the same or close to each other, the power consumption is stabilized, and the earphone loudspeaker cannot be interfered by electromagnetic radiation or interference is reduced.
While in other phases of the TWS headset operation, such as the bluetooth non-transmission phase when not connected back, the method is not performed in the solution of the present application, and the power consumption of the non-transmission phase is not increased to make the power consumption of the non-transmission phase close to that of the transmission phase, because the extra power consumption is avoided. For example, in a bluetooth connection state, a time slot is 625us, for a single slot frame, the duration of each frame of transmission and reception is less than 625us, and when the switching frequency of the power consumption is relatively back-connected, the frequency is relatively infrequent, the interference to the speaker is relatively small, and the anti-interference processing may not be performed. Therefore, the scheme only compensates the power of the Bluetooth non-transmission stage during the reconnection, the reconnection stage accounts for a short proportion of the whole time period used by the earphone, and once the ID packet sent by the main earphone responds to the terminal and enters the connection state, the main earphone does not need to send an ID packet every half time slot. The scheme only increases the power consumption in the non-transmission stage of the Bluetooth when the Bluetooth is connected back (namely the process that the main earphone continuously sends the ID packet), so that the influence on the whole power consumption of the Bluetooth earphone is small, the elimination or weakening of serious interference is realized through a small amount of power consumption, the serious interference is far greater than the loss, and the beneficial technical effect is achieved.
The following are embodiments of the apparatus of the present application that may be used to perform embodiments of the method of the present application.
