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 some, not all, embodiments of the present invention. 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.
The embodiment of the invention provides a sound channel switching method applied to electronic equipment.
Optionally, the first antenna and the second antenna are respectively disposed on two opposite sides of the electronic device, for example, a left side frame and a right side frame of the electronic device.
Alternatively, the electronic device may be a device capable of playing audio, such as a mobile phone, a tablet computer, a notebook computer, an MP3, an MP4, a wearable device, and the like.
Referring to fig. 1, fig. 1 is a flowchart of a channel switching method according to an embodiment of the present invention, and as shown in fig. 1, the channel switching method includes the following steps:
Optionally, the wireless connection may refer to a bluetooth connection, a wifi connection, a 3G connection, a 4G connection, a 5G connection, or the like.
In the embodiment of the invention, the earphone is a Bluetooth earphone, and the electronic equipment is provided with a Bluetooth chip and a Bluetooth antenna, so that the electronic equipment and the earphone can realize Bluetooth connection. For example, the first antenna and the second antenna are both bluetooth antennas, the first antenna and the second antenna are both connected to the same bluetooth chip, the bluetooth chip may be connected to a single-pole double-throw switch, a first output end of the single-pole double-throw switch is connected to the first antenna, a second output end of the single-pole double-throw switch is connected to the second antenna, and then the connection and control with the two bluetooth antennas are realized through one bluetooth chip, so that the hardware cost of the electronic device is saved. Or, the electronic device may be provided with a first bluetooth chip and a second bluetooth chip, the first antenna is connected with the first bluetooth chip, and the second antenna is connected with the second bluetooth chip, so that the two antennas are respectively controlled by different bluetooth chips.
Alternatively, in other alternative embodiments, the first antenna and the second antenna may be Ultra Wide Band (UWB) antennas, and the headset may be correspondingly provided with a UWB module, for example, the UWB module may be provided in a bluetooth chip of the headset, so that the headset can receive UWB pulse signals transmitted by the first antenna and the second antenna.
In the embodiment of the invention, under the condition that the electronic equipment is connected with the earphone in a Bluetooth mode, the first antenna and the second antenna which are arranged on the two opposite sides of the electronic equipment respectively send the first signal and the second signal to the left earphone, and the first antenna and the second antenna respectively send the third signal and the fourth signal to the right earphone.
102, acquiring wearing positions of the left earphone and the right earphone according to the time for sending the first signal and the second signal to the left earphone and the time for sending the third signal and the fourth signal to the right earphone.
In the embodiment of the present invention, the first antenna and the second antenna are respectively located on two opposite sides of the electronic device, and when the first antenna and the second antenna simultaneously transmit signals to the left earphone, since the first antenna and the second antenna are not located at the same position, a difference exists between a time when the left earphone receives the first signal and a time when the left earphone receives the second signal. Similarly, when the first antenna and the second antenna simultaneously transmit signals to the right earphone, the time when the right earphone receives the first signal and the time when the right earphone receives the second signal may be different. It can be understood that the wearing positions of the left earphone and the right earphone can be judged according to the time when the first signal and the second signal are sent to the left earphone and the time when the third signal and the fourth signal are sent to the right earphone.
Optionally, the step 102 may include:
acquiring the time for sending the first signal and the second signal to the left earphone, and judging that the left earphone is worn on the right ear under the condition that the time for sending the first signal to the left earphone is later than the time for sending the second signal to the left earphone;
and acquiring the time for sending the third signal and the fourth signal to the right earphone, and judging that the right earphone is worn on the left ear under the condition that the time for sending the third signal to the right earphone is earlier than the time for sending the fourth signal to the right earphone.
Referring to fig. 1a, in a case that a user faces a display screen of the electronic device 10, the first antenna 11 is disposed on a left frame of the electronic device 10, and the second antenna 12 is disposed on a right frame of the electronic device 10; when the electronic device 10 controls the first antenna 11 and the second antenna 12 to simultaneously transmit signals to the left earphone, that is, the first antenna 11 transmits the first signal S1, the second antenna 12 transmits the second signal S2, and if the time when the first signal S1 is acquired reaches the left earphone 21 is later than the time when the second signal S2 reaches the left earphone 21, which indicates that the second antenna 12 disposed on the right frame of the electronic device 10 is closer to the left earphone 21, it can be determined that the left earphone 21 is worn on the right ear of the user at this time.
In the same manner, when the electronic device 10 controls the first antenna 11 and the second antenna 12 to simultaneously transmit a signal to the right earphone 22, that is, the first antenna 11 transmits the third signal S3, and the second antenna 12 transmits the fourth signal S4, if the time of the third signal S3 reaching the right earphone 22 is earlier than the time of the fourth signal S4 reaching the right earphone 22, which indicates that the first antenna 11 disposed on the left frame of the electronic device 10 is closer to the right earphone 22, it can be determined that the right earphone 22 is worn on the left ear of the user at this time.
Of course, if the first signal S1 arrives at the left earphone 21 earlier than the second signal S2 arrives at the left earphone 21, it indicates that the left earphone 21 is worn on the left ear of the user; if the time when the third signal S3 reaches the right earphone 22 is later than the time when the fourth signal S4 reaches the right earphone 22, it indicates that the right earphone 22 is worn on the right ear of the user.
Therefore, the electronic equipment can simultaneously send signals to the left earphone and the right earphone by controlling the first antenna and the second antenna, and the wearing positions of the left earphone and the right earphone can be judged by comparing the receiving time of the signals, so that the electronic equipment is favorable for transmitting matched sound channel audio signals to the left earphone and the right earphone.
103, configuring a right channel audio signal for the left earphone and configuring a left channel audio signal for the right earphone under the condition that the left earphone is worn on the right ear and/or the right earphone is worn on the left ear.
It can be understood that, by sending signals to the left earphone and the right earphone through the first antenna and the second antenna, if it is determined that the left earphone is worn on the right ear and/or the right earphone is worn on the left ear, the electronic device configures the right channel audio signal for the left earphone and configures the left channel audio signal for the right earphone. Thus, even if the user wears the left and right earphones in reverse, the left ear still hears the left channel audio, and the right ear still hears the right channel audio.
It should be noted that, the switching of the left and right channel audio signals by the electronic device may be performed by exchanging the coding order of the left channel audio signal and the right channel audio signal during the process of coding the audio signals. For example, the electronic device is provided with a bluetooth chip, and the electronic device may transmit audio to the headset through a bluetooth transmission protocol. Specifically, after acquiring an audio file and decoding the audio file into an audio signal, the electronic device samples and encodes the audio signal based on a bluetooth transmission protocol, and encodes the audio signal into a left channel audio signal and a right channel audio signal; if the wearing positions of the left earphone and the right earphone obtained by the electronic device are opposite, the coding sequence of the left channel audio signal and the right channel audio signal can be exchanged in the coding process, so that the left channel audio signal is coded at the position originally corresponding to the right channel audio signal, and the right channel audio signal is coded at the position originally corresponding to the left channel audio signal. Thus, the left earphone receives i.e. the right channel audio signal and the right earphone receives i.e. the left channel audio signal.
According to the technical scheme provided by the embodiment of the invention, under the condition that the electronic equipment is wirelessly connected with the earphone, the first antenna and the second antenna which are arranged on the two opposite sides of the electronic equipment are controlled to respectively send signals to the left earphone and the right earphone, the wearing positions of the left earphone and the right earphone are determined by acquiring the time for sending the signals to the left earphone and the right earphone, and the right channel audio signal can be configured for the left earphone and the left channel audio signal can be configured for the right earphone under the condition that the left earphone is worn on the right ear and/or the right earphone is worn on the left ear. Therefore, even if the user wears the left and right earphones reversely, the user can be ensured to hear the audio suitable for the left ear and the right ear without taking off the earphones for replacement, and the listening experience of the user is ensured.
Or, in an optional implementation, after the electronic device acquires the wearing positions of the left earphone and the right earphone, the method may further include:
and sending prompt information to the earphone under the condition that the left earphone is worn on the right ear and/or the right earphone is worn on the left ear.
The prompt information may be audio information, for example, audio information that prompts the user to change wearing positions of the left earphone and the right earphone. The electronic equipment can understand that when the situation that the left earphone is worn on the right ear and/or the right earphone is worn on the left ear is obtained, the electronic equipment sends prompt information for changing the wearing positions of the left earphone and the right earphone to the earphones so as to remind a user of timely changing the wearing positions of the left earphone and the right earphone, and the auditory experience of the user is ensured.
Referring to fig. 2, fig. 2 is a flowchart of another channel switching method according to an embodiment of the present invention, where the electronic device includes a first antenna and a second antenna. As shown in fig. 2, the channel switching method includes the steps of:
This step can be implemented with reference to step 101 in the embodiment shown in fig. 1, and is not described in detail in the embodiment of the present invention to avoid repetition.
In the embodiment of the present invention, the first antenna and the second antenna are respectively located at two opposite sides of the electronic device, and when the first antenna and the second antenna simultaneously transmit signals to the left earphone, since the first antenna and the second antenna are not located at the same position, a phase difference also exists between the first signal and the second signal received by the left earphone. Similarly, when the first antenna and the second antenna simultaneously transmit signals to the right earphone, a phase difference also exists between the third signal and the fourth signal received by the right earphone.
Optionally, the step 202 may include:
acquiring a distance between the first antenna and the second antenna, calculating a first angle according to the distance and a phase difference between the first signal and the second signal, which are sent to the left earphone, and calculating a second angle according to the distance and a phase difference between the third signal and the fourth signal, which are sent to the right earphone;
and under the condition that the first angle is larger than the second angle, judging that the left earphone is worn on the right ear, and the right earphone is worn on the left ear.
It can be understood that the phase difference between the first signal and the second signal sent to the left earphone is related to the distance between the first antenna and the second antenna and the incident angle of the signal (i.e. the first angle), and the specific calculation formula is as follows:
wherein, theta1For the first angle, Δ Φ 1 is a phase difference between the first signal and the second signal sent to the left earphone, d is a distance between the first antenna and the second antenna, k is a first constant, λ is a second constant, and π is a third constant, and specific values of the constants may refer to related technologies, which is not described in detail in this embodiment. Thus, the first angle can be calculated according to the above formula.
In the same principle, the phase difference between the third signal and the fourth signal sent to the right earphone is related to the distance between the first antenna and the second antenna and the incident angle (i.e. the second angle) of the signal, and the specific calculation formula is as follows:
wherein, theta2And at the second angle, delta phi 2 is the phase difference of the third signal and the fourth signal sent to the left earphone, d is the distance between the first antenna and the second antenna, k is a first constant, lambda is a second constant, and pi is a third constant. The second angle can also be calculated according to the above formula.
In the embodiment of the present invention, when the first angle is greater than the second angle, it is described that the second antenna disposed on the right frame of the electronic device is closer to the left earphone, and it can be determined that the left earphone is worn on the right ear of the user at this time, and the right earphone is worn on the left ear of the user.
It can be understood that, by sending signals to the left earphone and the right earphone through the first antenna and the second antenna, if it is determined that the left earphone is worn on the right ear and/or the right earphone is worn on the left ear, the electronic device configures the right channel audio signal for the left earphone and configures the left channel audio signal for the right earphone. Thus, even if the user wears the left and right earphones in reverse, the left ear still hears the left channel audio, and the right ear still hears the right channel audio.
It should be noted that, for the switching of the left and right channel audio signals by the electronic device, reference may be made to the specific description in the embodiment illustrated in fig. 1, and details of the embodiment of the present invention are not repeated.
Optionally, after the electronic device obtains the wearing positions of the left earphone and the right earphone, the method may further include:
and sending prompt information to the earphone under the condition that the left earphone is worn on the right ear and/or the right earphone is worn on the left ear.
The prompt information may be audio information, for example, audio information that prompts the user to change wearing positions of the left earphone and the right earphone. The electronic equipment can understand that when the situation that the left earphone is worn on the right ear and/or the right earphone is worn on the left ear is obtained, the electronic equipment sends prompt information for changing the wearing positions of the left earphone and the right earphone to the earphones so as to remind a user of timely changing the wearing positions of the left earphone and the right earphone, and the auditory experience of the user is ensured.
According to the technical scheme provided by the embodiment of the invention, under the condition that the electronic equipment is wirelessly connected with the earphones, the first antenna and the second antenna which are arranged on the two opposite sides of the electronic equipment are controlled to respectively send signals to the left earphone and the right earphone, the wearing positions of the left earphone and the right earphone are determined by acquiring the phase difference of the signals sent to the left earphone and the right earphone and the distance calculation angle between the left earphone and the right earphone, and the right channel audio signal can be configured for the left earphone and the left channel audio signal can be configured for the right earphone under the condition that the left earphone is worn on the right ear and/or the right earphone is worn on the left ear. Therefore, even if the user wears the left and right earphones reversely, the user can be ensured to hear the audio suitable for the left ear and the right ear without taking off the earphones for replacement, and the listening experience of the user is ensured.
