Detailed Description
The following description of the embodiments of the present invention will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are some, but not all embodiments of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
The embodiment of the invention provides a sound channel switching method applied to electronic equipment, which comprises a first antenna and a second antenna.
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, tablet computer, notebook computer, MP3, MP4, wearable device, etc.
Referring to fig. 1, fig. 1 is a flowchart of a channel switching method according to an embodiment of the present invention, as shown in fig. 1, the channel switching method includes the following steps:
step 101, under the condition that the electronic device and the earphone are in wireless connection, the first antenna and the second antenna are controlled to respectively send a first signal and a second signal to the left earphone, and the first antenna and the second antenna are controlled to respectively send a third signal and a fourth signal to the right earphone.
Alternatively, the wireless connection may refer to a bluetooth connection, a wifi connection, a 3G connection, a 4G connection, a 5G connection, etc.
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 be connected by Bluetooth. For example, the first antenna and the second antenna are both bluetooth antennas, the first antenna and the second antenna are both connected with the same bluetooth chip, the bluetooth chip can be connected with a single-pole double-throw switch, the first output end of the single-pole double-throw switch is connected with the first antenna, the second output end of the single-pole double-throw switch is connected with the second antenna, and then connection and control with two bluetooth antennas are realized through one bluetooth chip, so that hardware cost of electronic equipment 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 optional embodiments, the first antenna and the second antenna may be Ultra Wideband (UWB) antennas, and the earphone is correspondingly provided with a UWB module, for example, may be provided in a bluetooth chip of the earphone, so that the earphone can receive UWB pulse signals sent by the first antenna and the second antenna.
In the embodiment of the invention, under the condition that the electronic equipment and the earphone are connected by Bluetooth, a first signal and a second signal are respectively sent to the left earphone through a first antenna and a second antenna which are arranged on two opposite sides of the electronic equipment, and a third signal and a fourth signal are respectively sent to the right earphone through the first antenna and the second antenna.
Step 102, 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, wearing positions of the left earphone and the right earphone are obtained.
In the embodiment of the invention, the first antenna and the second antenna are respectively positioned at two opposite sides of the electronic device, and when the first antenna and the second antenna send signals to the left earphone at the same time, as the first antenna and the second antenna are not positioned at the same position, the time when the left earphone receives the first signal and the time when the left earphone receives the second signal are different. 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 also have differences. It can be understood that the wearing positions of the left and right earphones can be judged according to the time when the first and second signals are transmitted to the left earphone and the time when the third and fourth signals are transmitted to the right earphone.
Optionally, the step 102 may include:
acquiring the time of the first signal and the second signal sent to the left earphone, and judging that the left earphone is worn on the right ear when the time of the first signal sent to the left earphone is later than the time of the second signal sent to the left earphone;
and acquiring the time when the third signal and the fourth signal are sent to the right earphone, and judging that the right earphone is worn on the left ear when the time when the third signal is sent to the right earphone is earlier than the time when the fourth signal is sent to the right earphone.
Referring to fig. 1a, in a case that a user faces a display screen of the electronic device 10, a first antenna 11 is disposed at a left frame of the electronic device 10, and a second antenna 12 is disposed at 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 and the second antenna 12 transmits the second signal S2, if the time when the first signal S1 arrives at the left earphone 21 is acquired later than the time when the second signal S2 arrives at the left earphone 21, it is determined that the second antenna 12 provided on the right frame of the electronic device 10 is closer to the left earphone 21, and then the left earphone 21 is worn on the right ear of the user.
In the same principle, when the electronic device 10 controls the first antenna 11 and the second antenna 12 to simultaneously transmit signals 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 third signal S3 arrives at the right earphone 22 earlier than the fourth signal S4 arrives at the right earphone 22, it is determined that the first antenna 11 disposed at the left frame of the electronic device 10 is closer to the right earphone 22, and the right earphone 22 is worn at the left ear of the user.
Of course, if the first signal S1 reaches the left earphone 21 earlier than the second signal S2 reaches the left earphone 21, it is indicated that the left earphone 21 is worn on the left ear of the user at this time; if the third signal S3 arrives at the right earphone 22 later than the fourth signal S4 arrives at the right earphone 22, this indicates that the right earphone 22 is worn on the right ear of the user.
Therefore, the electronic equipment can send signals to the left earphone and the right earphone simultaneously by controlling the first antenna and the second antenna, and can judge the wearing positions of the left earphone and the right earphone by comparing the receiving time of the signals, so that the electronic equipment is beneficial to transmitting matched sound channel audio signals to the left earphone and the right earphone.
Step 103, configuring a right channel audio signal for the left earphone and configuring a left channel audio signal for the right earphone when the left earphone is worn on the right ear and/or the right earphone is worn on the left ear.
It may be appreciated that, signals are sent to the left earphone and the right earphone through the first antenna and the second antenna, and 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 a right channel audio signal for the left earphone and configures a left channel audio signal for the right earphone. Thus, even if the user wears left and right headphones in reverse, the left ear still listens to the left channel audio and the right ear still listens to the right channel audio.
It should be noted that, the switching of the electronic device to the left and right channel audio signals may be that the coding sequence of the left channel audio signal and the right channel audio signal is exchanged 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 the electronic device acquires the audio file and decodes 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 electronic device obtains that the wearing positions of the left earphone and the right earphone are opposite, the coding sequence of the left channel audio signal and the right channel audio signal may be exchanged in the coding process, so as to code the left channel audio signal at the position corresponding to the original right channel audio signal, and code the right channel audio signal at the position corresponding to the original left channel audio signal. Thus, the left earpiece receives, i.e., right channel audio signals, and the right earpiece receives, i.e., left channel audio signals.
According to the technical scheme provided by the embodiment of the invention, under the condition that the electronic equipment is in wireless connection 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 of 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 earphone and/or the right earphone is worn on the left earphone. Therefore, even if the user wears left and right earphones reversely, the user does not need to take off the earphones to replace, the user can hear the audio suitable for the left ear and the right ear, and the hearing experience of the user is ensured.
Or, in an alternative embodiment, 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 when the left earphone is worn on the right ear and/or the right earphone is worn on the left ear.
The prompting information can be audio information, for example, the prompting information can be audio information prompting the user to change the wearing positions of the left earphone and the right earphone. It can be understood that when the electronic device obtains that the left earphone is worn on the right ear and/or the right earphone is worn on the left ear, the electronic device sends a prompt message for exchanging the wearing positions of the left earphone and the right earphone to the earphone so as to remind the user to timely replace the wearing positions of the left earphone and the right earphone and ensure the hearing experience of the user.
Referring to fig. 2, fig. 2 is a flowchart of another channel switching method provided in 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:
step 201, under the condition that the electronic device establishes wireless connection with the earphone, the first antenna and the second antenna are controlled to respectively send a first signal and a second signal to the left earphone, and the first antenna and the second antenna are controlled to respectively send a third signal and a fourth signal to the right earphone.
This step may be performed with reference to step 101 in the embodiment shown in fig. 1, and in order to avoid repetition, details are not described in the embodiment of the present invention.
Step 202, obtaining 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 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 sent to the right earphone, so as to obtain wearing positions of the left earphone and the right earphone.
In the embodiment of the invention, the first antenna and the second antenna are respectively positioned at two opposite sides of the electronic device, and when the first antenna and the second antenna send signals to the left earphone at the same time, as the first antenna and the second antenna are not positioned at the same position, a phase difference exists between the first signal and the second signal received by the left earphone. Similarly, when the first antenna and the second antenna send signals to the right earphone at the same time, a phase difference exists between the third signal and the fourth signal received by the right earphone.
Optionally, the step 202 may include:
acquiring the distance between the first antenna and the second antenna, calculating a first angle according to the distance and the phase difference between the first signal and the second signal sent to the left earphone, and calculating a second angle according to the distance and the phase difference between the third signal and the fourth signal 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 θ 1 For the first angle, ΔΦ1 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, pi is a third constant, and specific values of the constants may refer to related technologies, which will not be 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 signal incident angle (i.e. the second angle), and the specific calculation formula is as follows:
wherein θ 2 For the second angle, ΔΦ2 is the phase difference between the third signal and the fourth signal sent to the left earpiece, d is the distance between the first antenna and the second antenna, k is the first constant, λ is the second constant, and pi is the third constant. The second angle can also be calculated according to the above formula.
In the embodiment of the invention, when the first angle is larger than the second angle, the second antenna arranged on the right frame of the electronic device is closer to the left earphone, so that the left earphone is worn on the right ear of the user at the moment, and the right earphone is worn on the left ear of the user.
Step 203, configuring a right channel audio signal for the left earphone and configuring a left channel audio signal for the right earphone when the left earphone is worn on the right ear and/or the right earphone is worn on the left ear.
It may be appreciated that, signals are sent to the left earphone and the right earphone through the first antenna and the second antenna, and 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 a right channel audio signal for the left earphone and configures a left channel audio signal for the right earphone. Thus, even if the user wears left and right headphones in reverse, the left ear still listens to the left channel audio and the right ear still listens to the right channel audio.
It should be noted that, the switching of the electronic device to the left and right channel audio signals may refer to the specific description in the embodiment described in fig. 1, and the embodiments of the present invention are not repeated.
Optionally, after acquiring the wearing positions of the left earphone and the right earphone, the electronic device may further include:
and sending prompt information to the earphone when the left earphone is worn on the right ear and/or the right earphone is worn on the left ear.
The prompting information can be audio information, for example, the prompting information can be audio information prompting the user to change the wearing positions of the left earphone and the right earphone. It can be understood that when the electronic device obtains that the left earphone is worn on the right ear and/or the right earphone is worn on the left ear, the electronic device sends a prompt message for exchanging the wearing positions of the left earphone and the right earphone to the earphone so as to remind the user to timely replace the wearing positions of the left earphone and the right earphone and ensure the hearing experience of the user.
According to the technical scheme provided by the embodiment of the invention, under the condition that the electronic equipment is in wireless connection 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 phase difference 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 earphone and/or the right earphone is worn on the left earphone. Therefore, even if the user wears left and right earphones reversely, the user does not need to take off the earphones to replace, the user can hear the audio suitable for the left ear and the right ear, and the hearing experience of the user is ensured.
