Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As will be appreciated by one skilled in the art, embodiments of the present invention may be embodied as a system, apparatus, device, method, or computer program product. Accordingly, the present disclosure may be embodied in the form of: entirely hardware, entirely software (including firmware, resident software, micro-code, etc.), or a combination of hardware and software.
The principles and spirit of the present invention are explained in detail below with reference to several representative embodiments of the invention.
The transmitting channel of the wireless earphone generally comprises a modulator, a DAC, a mixer, a power amplifier and the like, wherein the power amplifier is an amplifying circuit capable of providing enough signal power for an antenna, the main function is to amplify a radio-frequency signal with small power generated by the modulator and feed the radio-frequency signal to the antenna for radiation, the radio-frequency signal is the most core component of the radio-frequency front end of the wireless communication equipment, the performance of the radio-frequency front end directly determines the communication distance, the signal quality and the standby time (or power consumption) of the wireless terminal, and the power amplifier is also the device with the largest power consumption of the radio-frequency front end. Wherein, for DAC, mixer and power amplifier, each stage has adjustable gain. Conventionally, reducing the transmit power can reduce the input data amplitude, and can also reduce the gain of one or more stages of the DAC, mixer, power amplifier. However, if the gain is reduced at the DAC or mixer or power amplifier, the transmit power is reduced with little to no reduction in power consumption. This is because power consumption is mainly consumed in the power amplifier, and the gain of a certain stage or stages of the DAC, the mixer, and the power amplifier is reduced, but power consumption caused by the dc bias of the power amplifier is not reduced. Thus, despite the reduction in transmit power, the power consumed by the power amplifier is not reduced proportionally, or even hardly.
Therefore, the technical scheme of the invention discloses a wireless earphone and a communication method of the wireless earphone, wherein a plurality of radio frequency power amplifiers are used in a transmitting channel of the wireless earphone, and when the transmitting power needs to be reduced, the radio frequency power amplifiers can be used less, so that the power consumption is reduced. Specifically, by detecting the data transmission condition of the wireless earphone, when the signal transmission of the wireless earphone is better, one radio frequency power amplifier is used for working, namely when the signal transmission of the wireless earphone is better, the transmission power can be reduced, and in order to reduce the transmission power and reduce the power consumption better, only one power amplifier working mode is used, so that when the wireless earphone transmits low power, compared with a plurality of power amplifier working modes, high transmission efficiency can be maintained, and the power consumption is reduced; when the signal transmission of the wireless earphone is poor, a plurality of power amplifier working modes are used, namely a plurality of power amplifiers are started to work, so that high transmitting power (which cannot be output by one power amplifier) can be output, better radio frequency performance is achieved, and the balance optimization of the radio frequency performance and the earphone power consumption is realized. It can be understood by those skilled in the art that the "power amplifier", "radio frequency power amplifier" and "radio frequency power amplifier" mentioned in the embodiments of the present invention all refer to PA devices applied in wireless headsets, and refer to the same in the same embodiment.
Fig. 1 is a schematic structural diagram of a wireless headset according to an embodiment of the present invention. In this embodiment, the wireless headset comprises a first headset 11 and a second headset 12. Each of the first earphone 11 and the second earphone 12 includes: a power amplifier group 110 including at least two radio frequency power amplifiers; and a processor 111 configured to: and determining to adopt one or more of the at least two radio frequency power amplifiers according to the data transmission condition of the wireless headset. The two rf power amplifiers in fig. 1 are shown as an example, and 3, 4 or even more rf power amplifiers may be included according to the actual circuit situation of the wireless headset.
In a wireless headset, one or more rf power amplifiers are typically used to power amplify the wireless rf signal for retransmission to another device (e.g., another headset, other smart device, etc.) via the transmitting device (including the antenna) of the headset. When the output power of a single radio frequency power amplifier does not reach the power required by application, the output powers of a plurality of radio frequency power amplifiers can be synthesized or added, but when the output power requirement is lower, the plurality of radio frequency power amplifiers work simultaneously, and the transmitting power consumption is increased. This is because, when the requirement for output power is low, if the rf power amplifier is not reduced, the efficiency of the rf power amplifier is reduced only by reducing the gain of the rf power amplifier or reducing the input of the rf power amplifier, and the power consumption of the rf power amplifier cannot be reduced well. If the number of the radio frequency power amplifiers is reduced, for example, the number of the radio frequency power amplifiers is changed from 2 to one, the radio frequency power amplifiers are changed from 2 added power consumptions to one power consumption of the radio frequency power amplifiers, and when the two radio frequency power amplifiers are consistent, approximately half of the power consumption is reduced.
When the earphone is used for ear communication, the two earphones are often shielded by the head bags of users, the shielding degree of different users is different, the modes of wearing the earphones by different users are different, and the power of the other earphone for receiving signals is different. Therefore, the number of enabled radio frequency power amplifiers can be determined according to the data transmission condition. When the smart device is close to the earphone or/and has little shielding, the power of the wireless signal transmitted by the earphone can be reduced, and at the moment, in order to reduce the power consumption, part of the radio frequency power amplifier can be turned off. When the data transmission condition is better, less radio frequency power amplifiers are configured, when the data transmission condition is good, only one radio frequency power amplifier needs to be enabled, and the other radio frequency power amplifiers are turned off. When the data transmission condition is poor, all N radio frequency power amplifiers can be enabled, so that the transmitting power is maximum. And the larger transmitting power can resist larger wireless interference.
In the present invention, the processor 111 may comprise a general-purpose processor or a dedicated processor dedicated to a particular process, one or more programmable circuits, one or more dedicated circuits, or a combination thereof. For example, the processor 111 may be any one or a combination of a Micro Processing Unit (MPU), an SOC (system on chip), a DSP (digital processing). The programmable circuit may be, for example, a Field Programmable Gate Array (FPGA), but is not limited thereto. The dedicated circuit may be, for example, an Application Specific Integrated Circuit (ASIC), but is not limited thereto.
In the embodiment of the present invention, the processor 111 collects the data transmission status of the wireless headset, and determines to amplify the signal power by using one or more of the at least two rf power amplifiers according to the data transmission status, so that when the data transmission status is good, one rf power amplifier is used to operate to reduce power consumption, and when the signal transmission of the wireless headset is poor, a plurality of rf power amplifiers are turned on to operate to achieve good rf performance.
In some embodiments, the data transmission condition of the wireless headset may be determined by an amount of buffered audio data of the wireless headset. Under the condition that the amount of the cached audio data of the wireless earphone is larger than a first threshold value, a radio frequency power amplifier is adopted; under the condition that the amount of the cached audio data of the wireless earphone is smaller than a second threshold value, a plurality of radio frequency power amplifiers are adopted; wherein the second threshold is less than the first threshold. If the amount of buffered audio data of the wireless headset is between the first threshold and the second threshold, the current radio frequency power amplifier mode may be kept unchanged. In another embodiment, the first threshold and the second threshold may be the same, and only one threshold is set to determine to use one rf power amplifier or a plurality of rf power amplifiers. It can be understood that, when the amount of the buffered audio data of the wireless headset is greater than a certain threshold, it proves that the radio frequency transmission efficiency of the wireless headset is better, and at this time, only one radio frequency power amplifier may be turned on to reduce the power consumption of the whole headset. However, when the amount of the buffered audio data of the wireless headset is smaller than a certain threshold, it is proved that the signal transmission quality is low, and at this time, more radio frequency power amplifiers need to be turned on to improve the radio frequency performance and improve the anti-interference capability of wireless transmission, thereby improving the data transmission capability of the wireless headset. In this embodiment, the first threshold (e.g., corresponding to 80ms audio data) and the second threshold (e.g., corresponding to 30ms audio data) may be determined empirically by one skilled in the art.
In other embodiments, the data transmission condition of the wireless headset is determined by a data transmission error parameter of the wireless headset. The data transmission error parameter is determined based on at least one of a frame error rate, a packet error rate, a bit error rate, and a packet loss rate of data transmission of the wireless headset. Determining to employ a plurality of radio frequency power amplifiers if the data transmission error parameter of the wireless headset is greater than a third threshold. It can be understood that when at least one of the frame error rate, the packet error rate, the bit error rate, and the packet loss rate of the wireless headset is higher, for example, higher than a certain threshold, it is proved that the signal transmission quality is lower, and at this time, more radio frequency power amplifiers need to be turned on to improve the radio frequency performance and improve the interference resistance of wireless transmission, so that the high efficiency of data transmission of the wireless headset is ensured at first. In the present embodiment, the third threshold value may be empirically determined by those skilled in the art.
In other embodiments, the data transmission condition of the wireless headset is determined by RSSI of a received wireless signal of the wireless headset; determining to employ a plurality of radio frequency power amplifiers if the RSSI of the wireless headset is less than a fourth threshold. It can be understood that, when the RSSI value of the wireless signal received by the wireless headset is low, for example, lower than a certain threshold, it is proved that the wireless signal received by the wireless headset has a small amplitude and is susceptible to wireless interference, and thus the signal transmission quality may be low, and at this time, more radio frequency power amplifiers need to be turned on to improve the radio frequency performance, and ensure the high efficiency of data transmission of the wireless headset. In the present embodiment, the fourth threshold value may be empirically determined by those skilled in the art.
In some embodiments, the power amplifier group 110 includes at least two rf power amplifiers, such as the embodiment of fig. 1, which includes only a first rf power amplifier and a second rf power amplifier. Therefore, whether the data receiving condition is determined according to the amount of the buffered audio data of the wireless earphone, the RSSI received by the wireless earphone, or the received bit error rate/packet error rate/frame error rate/packet loss rate, only one threshold needs to be set, and then one radio frequency power amplifier or two radio frequency power amplifiers can be used. In other embodiments, if the power amplifier group 101 includes more than two rf power amplifiers, after one or more thresholds are set, another threshold may be set, and it is determined whether two or three or more rf power amplifiers are used when multiple rf power amplifiers are used, which may be set by a person skilled in the art according to practical working experience, so as to set the usage of multiple rf power amplifiers more accurately according to data transmission conditions, thereby implementing balanced optimization of rf performance and headset power consumption.
Fig. 2 shows a schematic diagram of communication connections between respective headsets of a wireless headset and between the headsets and a smart device according to an embodiment of the disclosure. As shown in fig. 2, the wireless headset and smart device established communication system 100 includes a smart device 101, a first headset 102, and a second headset 103. The smart device 101 may be various portable smart terminals including, but not limited to, a mobile phone, a tablet computer, a wearable smart device, and the like. In this embodiment, the first earphone 102 establishes the first communication connection 104 with the intelligent device 101, directly obtains audio data from the intelligent device 101 through the first communication connection 104, and returns ACK/NACK information to the intelligent device 101 according to the receiving condition. In addition, the first earphone 102 further establishes a second communication connection 105 with the second earphone 103, and after receiving the audio data sent by the smart device 101, the first earphone 102 can forward the audio data to the second earphone 103 through the second communication connection 105. In this embodiment, the first wireless link 104 and the second wireless link 105 may be any one of a WIFI communication mode, a classic bluetooth communication mode, a BLE communication mode, an LE audio, a Zigbee communication mode, and a UWB communication mode.
In this embodiment, for the first earphone 102, when the first earphone 102 is connected to the smart device 101 through the first wireless link 104, it is determined to use one or more of at least two rf power amplifiers in the first earphone 102 to communicate with the smart device according to the data transmission condition of the first earphone 102 in the first wireless link 104; when the first earphone 102 is connected with the second earphone 103 through the second wireless link 105, it is determined to use one or more of at least two radio frequency power amplifiers in the first earphone 102 to communicate with the second earphone 103 according to the data transmission condition of the first earphone 102 in the second wireless link 105.
In this embodiment, for the second earphone 103, when the second earphone 103 is connected to the first earphone 102 through the second wireless link 105, it is determined to use one or more of at least two rf power amplifiers in the second earphone 103 to communicate with the first earphone according to the data transmission condition of the second earphone 103 in the second wireless link 105.
Fig. 3 shows a schematic diagram of communication connections between respective headsets of a wireless headset and between the headsets and a smart device according to another embodiment of the disclosure. As shown in fig. 3, the wireless headset and smart device established communication system 100 includes a smart device 101, a first headset 102, and a second headset 103. The smart device 101 may be various portable smart terminals including, but not limited to, a mobile phone, a tablet computer, a wearable smart device, and the like. In this embodiment, the first earphone 102 establishes a first communication connection 104 with the smart device 101, and directly obtains audio data from the smart device 101 through the first communication connection 104, and the first earphone 102 also establishes a second communication connection 105 with the second earphone 103, and the first earphone 102 can transmit relevant communication parameters to the second earphone 103, so that the second earphone 103 listens to the first communication connection, i.e. the listening connection 106, by using the relevant communication parameters. In some embodiments, the relevant communication parameters include, but are not limited to, a communication connection address of the smart device 101, encryption parameter information of the communication connection, etc., such that the second earpiece 103 need not perform pairing and establishment of the communication connection, but may masquerade as the first earpiece 102 to listen and receive signals transmitted by the smart device 101 via the first communication connection 104. By listening to the first communication connection 104 by the second earphone 103 without repeating the establishment of the first communication connection 104 or forwarding all audio data received by the first earphone 102 from the smart device 101 to the second earphone 103, information transmission between the smart device 101 and the two earphones 102 and 103 can be more efficiently achieved, and the time difference between the information received by the first earphone 102 and the second earphone 103 can be reduced, thereby improving the synchronization thereof. In this embodiment, the second earphone 103 sends an indication frame to the first earphone 102 to indicate whether the second earphone 103 correctly receives the audio data from the smart device 101, and the first earphone 102 may return ACK/NACK information to the smart device 101 through the first communication connection 104. When the first earphone 102 and the second earphone 103 both receive correct audio data, the first earphone 102 returns ACK to the smart device 101, otherwise NACK is returned to the smart device 101. In another embodiment, the first earpiece 102 sends an indication frame to the second earpiece 103, indicating whether the first earpiece 102 correctly received audio data from the smart device 101, and ACK/NACK information may be returned by the second earpiece 103 to the smart device 101 over the listening connection 106. When both the first earphone 102 and the second earphone 103 receive correct audio data, an ACK is returned by the second earphone 103 to the smart device 101, otherwise a NACK is returned to the smart device 101.
This embodiment differs from the embodiment shown in fig. 2 in that the second earpiece 103 also has a listening connection 106 established with the smart device 101. Therefore, in addition to the same power amplifier selection according to the data transmission condition of the first wireless connection 104 and the second wireless connection 105 as the embodiment shown in fig. 2, the method further includes: for the second earphone 103, when the second earphone 103 communicates with the smart device 101 through the listening connection 106, it is determined to use one or more of at least two radio frequency power amplifiers in the second earphone 103 to communicate with the smart device 101 according to the data transmission condition of the second earphone 103 in the listening connection 106.
