[0035] Such as image 3 Shown is a flow chart of the signal switching method in one embodiment. The signal switching method in this embodiment runs on figure 1 Take the terminal and/or headset as an example in the description. The signal switching method is applied to a device with audio communication function, the device includes such as Figure 4 As shown in the audio processing circuit, the audio processing circuit includes a signal converter, a signal switching unit and at least two audio transceiver units. The signal switching party includes the following steps 302 to 306:

[0036] Step 302: Acquire audio signals received by at least two of the audio transceiver units.

[0037] Among them, the audio processing circuit is used to realize the signal conversion process, for example, the audio processing circuit processes the uplink voice and the downlink voice during a voice call. When the audio processing circuit processes the uplink voice, it converts the sound wave signal into an electrical signal and transmits it to the line Medium; When the audio processing circuit processes the downlink voice, it converts the electrical signal into a sound wave signal and transmits it to the speaker. The audio transceiver unit is used to collect audio signals or send (play) audio signals. Optionally, the audio transceiver unit includes a speaker and a microphone. The speaker can convert electrical signals into acoustic signals, and the microphone can convert audio signals into electrical signals. That is, the audio processing circuit implements the audio signal transceiving process through the audio transceiving unit.

[0038] When the audio signal is processed by the audio processing circuit, the audio signals received by at least two audio transceiver units are acquired to obtain at least two audio signals.

[0039] Step 304: Connect at least two channels of the audio signals to the signal converter through the signal switching unit.

[0040] Wherein, the signal switching unit is used to switch between multiple audio signals, and the signal switching unit adopts a single-pole multi-throw switch. Optionally, the signal switching unit may also be a radio frequency switch. The signal converter is used to convert analog and digital signals. The signal converter includes ADC (Analog-to-Digital Converter) and DAC (Digital-to-Analog Converter). When the signal When the converter is an ADC, the analog signal can be converted into a digital signal, and when the signal converter is a DAC, the digital signal can be converted into an analog signal.

[0041] Specifically, the signal switching unit includes a control terminal and at least two switching terminals, the control terminal is connected to the signal converter, and the switching terminal is connected to each audio transceiver unit in a one-to-one correspondence. The audio signal is connected to the signal converter through the signal switching unit, so that a signal transmission path is formed between the signal converter and at least two audio transceiver units.

[0042] Step 306: Control the signal switching unit to switch the signal transmission path according to a preset switching strategy, so that the signal converter performs signal conversion on at least two channels of the audio signal.

[0043] Specifically, when the signal converter and the two audio transceiving units form at least two signal transmission paths, the signal switching unit may be controlled to sequentially switch between the two signal transmission paths according to a preset time interval. Among them, in order to make the signal more continuous, the switching interval is set to time division switching. The time division switching method divides the time into several non-overlapping time slots, establishes different sub-channels from different time slots, and exchanges the network through time slots. The time slot movement of the signal is completed, thereby realizing the switching of audio signals between different signal transmission paths.

[0044] Optionally, the signal transmission path may also be switched according to the audio signal strength, the signal strength of the audio signal received by each audio transceiver unit is detected, and the signal switching unit is controlled to switch to the signal transmission path with the highest audio signal strength. For example, when accessing the audio signal collected by each audio transceiver unit, it is necessary to detect and record the signal strength of the current audio signal. The signal strength reflects the sound strength. Compare the signal strength of each audio signal and switch the signal. The switching end of the unit is connected to the signal transceiving unit corresponding to the audio signal with the highest signal strength.

[0045] The signal transmission path is switched by controlling the signal switching unit, so that the signal converter performs signal conversion on at least two audio signals. In this embodiment, the signal converter is an ADC, which converts at least two audio signals into electrical signals, where the audio signals are analog signals and the electrical signals are digital signals.

[0046] In the above signal switching method, by acquiring at least two audio signals received by the audio transceiving unit, at least two channels of the audio signal are connected to the signal converter through the signal switching unit, and the control station is controlled according to a preset switching strategy. The signal switching unit switches the signal transmission path, so that the signal converter performs signal conversion on at least two channels of the audio signal. Through the above method, the ADC in the circuit is reduced, the hardware cost of the ADC is saved, and the utilization of hardware resources is improved.

[0047] In one embodiment, the audio transceiver unit includes an electro-acoustic transducer, such as Figure 5 As shown, the acquiring audio signals received by at least two audio transceiver units includes the following steps 502 and/or step 504:

[0048] Step 502: Receive the audio signal obtained by the electroacoustic transducer on the terminal.

[0049] Specifically, the terminal has an electroacoustic transducer, which refers to a device used to receive electrical (or acoustic) input signals and convert them into acoustic (or electrical) output signals, such as speakers and microphones. And receiver etc. When performing audio communication through the terminal, the audio signal obtained by the electroacoustic transducer on the terminal is received. For example, when a call is made through the terminal, the microphone on the terminal collects the sound wave signal generated by the vibration of the user's vocal cord, and transmits the sound wave signal to the audio processing unit for signal conversion processing.

[0050] Step 504: When the terminal is in a communication connection with the earphone, receive the audio signal obtained by the electroacoustic transducer on the earphone.

[0051] When a headset is connected to the terminal, the audio signal sent from the terminal and the audio signal that the terminal needs to collect are all carried through the headset by default. When the audio processing circuit processes the audio signals collected by the signal transceiver unit, it receives the audio signals obtained by the electroacoustic transducer on the earphone. Wherein, the audio signal includes user voice and/or surrounding environment sound.

[0052] Specifically, the earphone includes an electro-acoustic transducer, and the electro-acoustic transducer can be used as a speaker to convert the electrical signal corresponding to the audio signal into a sound wave signal that the user can hear. At the same time, the electro-acoustic transducer is very sensitive to sound waves. When receiving the sound waves, it can cause the speaker cone to vibrate, and drive the coil connected to the cone to cut the magnetic field lines in the magnetic field of the permanent magnet, thereby generating a motion that follows the sound waves. The changing electric current (the phenomenon of generating electric current is called electromagnetic induction phenomenon in physics), and at the same time, the electromotive force of audio frequency will be output at both ends of the coil. Therefore, the electroacoustic converter can also collect audio signals. That is, the electroacoustic transducer can also be used as a microphone.

[0053] Electroacoustic transducers, although their types, functions or working conditions are different, they all include two basic components, namely the electrical system and the mechanical vibration system. Inside the electroacoustic transducer, the electrical system and the mechanical vibration system pass between Certain physical effects are interconnected to complete energy conversion.

[0054] Optionally, audio signals can also be collected through a microphone set in the headset. The microphone can be set on the headset housing or on the headset cable; it is understandable that the microphone can also be set near the user’s vocal cord. Any location in the vicinity is not limited in this embodiment.

[0055] In one embodiment, when a call is made through a headset, the user's voice is collected based on an electroacoustic transducer that plays an audio signal in the headset; where the electroacoustic transducer includes a left microphone and a right microphone. According to the left microphone and the right microphone on the headset, the left channel signal and the right channel signal are obtained respectively.

[0056] It is understandable that a headset usually includes a left-channel headset and a right-channel headset. When the electroacoustic transducer that plays the audio signal in the headset is used as a microphone to collect sound, the headset has a left microphone and a right microphone, and the left microphone The audio signal collected by the microphone is the left channel signal, and the audio signal collected by the right microphone is the right channel signal. Among them, the left channel signal is a sound wave signal collected by the left microphone simulating the hearing range of a human left ear, and the right channel signal is a sound wave signal collected by the right microphone simulating the hearing range of a human right ear.

[0057] Further, the electroacoustic transducer on the earphone transmits the collected left and right channel signals to the audio signal processing circuit, and the audio signal processing circuit controls the signal switching unit to control the left channel signal and the right channel signal according to a preset time interval. The channel signal is switched, so that the signal converter converts the left channel signal and the right channel signal collected by the earphone into an electrical signal for sending call information.

[0058] Optionally, the audio processing circuit may also be provided in the headset, and the headset further includes a processing chip, and the processing chip completes the audio signal processing process.

[0059] In one embodiment, such as Image 6 As shown, the signal switching method further includes the following steps 602 to 606:

[0060] Step 602: Obtain the electrical signal sent by the device, and obtain two audio signals after the electrical signal is converted by the signal converter.

[0061] The device includes a terminal and earphones connected in communication. When the audio signal is played through the audio processing circuit on the device, the electrical signal sent by the device is obtained, and the electrical signal is converted by a signal converter to obtain two audio signals. For example, when playing music through headphones, the terminal sends an electrical signal containing music information to a DAC, and the DAC converts the electrical signal containing music information into a left channel signal and a right channel signal for the user to listen to with both ears.

[0062] Step 604: Connect the two audio signals to the corresponding audio transceiver unit through the signal switching unit.

[0063] Specifically, the signal switching unit includes a control terminal and at least two switching terminals, the control terminal is connected to the signal converter, the switching terminal is connected to each audio transceiver unit in a one-to-one correspondence, and two audio signals are passed through The signal switching unit is respectively connected to the corresponding audio transceiver unit, so that a signal transmission path is formed between the signal converter and the two audio transceiver units. For example, the audio transceiver unit includes an electro-acoustic transducer on the earphone. The electro-acoustic transducer includes a left speaker and a right speaker. The left speaker and the right speaker are used to play the left channel signal and the right channel signal respectively, which are converted by DAC The resulting left channel signal and right channel signal are respectively transmitted to the signal transmission paths corresponding to the left speaker and the right speaker on the earphone.

[0064] Step 606: Control the signal switching unit to switch the two channels of audio signals according to the preset time interval, so that the two channels of audio signals are respectively used for audio playback through the corresponding audio transceiver unit.

[0065] Among them, in order to make the signal more continuous, the switching interval is set to time division switching. The time division switching method divides the time into several non-overlapping time slots, establishes different sub-channels from different time slots, and exchanges the network through time slots. The time slot movement of the signal is completed, thereby realizing the switching of audio signals between different signal transmission paths. For example, if the preset time interval is 5ms, the signal switch will switch every 5ms. When playing music, the left channel signal and the right channel signal after DAC conversion will pass through the left speaker of the earphone at a time interval of 5ms. And the right speaker to switch between the left and right channels.

[0066] In the signal switching method provided by this embodiment, the electrical signal sent by the device is obtained, the electrical signal is converted by the signal converter to obtain two audio signals, and the two audio signals are passed through the The signal switching unit accesses the corresponding audio transceiver unit, and controls the signal switching unit to switch the two audio signals according to a preset time interval, so that the two audio signals are respectively played through the corresponding audio transceiver unit , Reducing the use of DAC in the circuit, saving the hardware cost of the DAC, and improving the utilization of hardware resources.
