Audio output switching method, method for feeding back earphone wearing state, device and earphone

technical field

The invention relates to the field of audio processing, in particular to an audio output switching method, a method and device for feeding back the wearing state of an earphone, and an earphone.

Background technique

With the popularization of terminal mobile phones, more and more users use mobile phones as media tools for watching videos, listening to music, listening to radio, and calling. However, in some scenarios where headphones are used, the switching of audio output channels is very inhumane. For example, when the user plugs in the earphone to watch video or listen to the radio, after a long time or the user's environment changes, when the user takes the earphone out of the ear, the user will expect the sound It can be broadcast directly from the speaker of the terminal. At this time, the user needs to manually pull out the earphone from the terminal, that is, the user needs to manually turn on the external speaker, which brings inconvenience to the user. For another example, when the user is driving a vehicle, the mobile phone is connected to a wired headset or a Bluetooth headset to make a call. If the user wants to switch to the hands-free after the call is over or during the call, the user needs to take off the headset and then turn on the hands-free function. Operation also brings inconvenience to users. It can be seen that how to improve the intelligent switching of audio output channels and improve the user experience of end users has become an urgent problem to be solved.

At present, in the prior art, the voice channel can be switched by plugging and unplugging the earphone. For example, the user inserts the earphone into the terminal to make a call or listen to music, and after the earphone is dialed out from the mobile phone, it is automatically switched to the mobile phone call. Or, during a call through the earphone, the user manually touches the function button to switch the call mode to hands-free. However, most terminals currently do not support the insertion of earphones, and switch the audio playback to external playback. However, manual switching of audio channels cannot satisfy the user in various scenarios of audio switching scenarios. When the user is driving the vehicle, the user makes a call through the Bluetooth headset/ordinary headset. After the call is completed, if the user needs to switch the audio to the normal mobile phone Mode or hands-free mode, you need to manually unplug the headset or manually turn off the Bluetooth connection, which is very dangerous for users who are driving. Moreover, the user hears the audio through the earphone. After pulling out the earplug from the ear, the audio is still sent from the earphone. The audio can only be transmitted from the external device of the terminal after the connection between the earphone and the terminal must be manually disconnected. The operation steps are very cumbersome. resulting in poor user experience.

The method for feeding back the wearing state of the earphone provided in this embodiment can detect the wearing state of the user, and send the wearing state of the user to the terminal, so that the terminal can determine whether the earphone is currently worn by the user according to the earphone wearing state information sent by the earphone, so as to determine whether to switch The current audio output channel of the terminal enables the terminal to automatically switch the audio output channel of the terminal according to the situation when the earphone is worn, making the audio playback of the terminal more intelligent.

third embodiment

This embodiment provides a kind of earphone, and this earphone can be earplug or earphone, and this earphone can comprise at least five pressure contacts, and this pressure contact is arranged on the contact place of user's ear when earphone is worn by user, for example, can be The circle part where the earphone is in contact with the ear canal is evenly distributed with five contacts similar to the touch screen. As shown in Figure 3, the five pressure contacts are evenly arranged on the periphery of the earphone hole, and each pressure contact of the earphone can be A pressure sensor is set, which can also be a pressure sensing element such as a piezocapacitance, and the pressure sensor is used to detect the pressure signal received by the pressure contact; the earphone also has a second sending module, which is used to transmit the pressure signal detected by the pressure sensor The pressure signal is converted into the first audio electrical signal and then sent to the terminal.

Preferably, the microphone input signal line of the headset in this embodiment supports the voltage of the second audio electrical signal converted from the voice signal received by the microphone, and the voltage of the first audio electrical signal, the voltage of the first audio point signal The value is greater than the voltage value of the second audio electrical signal. Preferably, the microphone input signal line of the existing earphone can be modified to support a larger voltage range.

Functionally, the headset provided in this embodiment may include the following components:

Headphone contact sensing module: When the headset is inserted into the terminal or the Bluetooth headset is connected to the mobile phone, the 5 contacts on the headset are powered on. The 5 contacts are similar to the contacts on the touch screen of the mobile phone. If the contact is not squeezed, the default signal of the contact is "0", and when the contact is pressed, the active feedback signal of the contact is "1". There are 5 contacts evenly distributed in the earplug part of the mobile phone. In order to facilitate the identification of the contacts, ID (identification) labels are added to the 5 contacts, so the format of the contact signal can be, 1, 0. This signal indicates that the ID is 1. If the signal of the contact is 0, it means that the contact does not detect pressure at this time. The headphone contact sensing module periodically (that is, the above-mentioned first preset time period) (according to the user's usage habits, the collection period is defined as 0.5S) obtains the current contact status information from the contact and sends it to the sensing data transmission module .

There are four signal lines in the headphone jack, which are left channel, right channel, ground and microphone. The direction of each signal in the interface is fixed, the left channel and the right channel are used to drive the earphone, so it is the output for the mobile phone; the microphone is used to collect the voice signal, so the direction is the input for the mobile phone, and the microphone (microphone) converts the mechanical vibration Converted to an electrical signal, analog audio technology uses the magnitude of an analog voltage to indicate the strength of a sound. Compared with mobile phones, the headphone jack interface provides two output channels and one input channel, which can meet the requirements of two-way communication between mobile phones and hardware peripherals.

The contact signal collected by the module is an electrical signal, and the electrical signal is converted into an audio electrical signal (fixed voltage value) and input to the microphone input connection line.

It should be noted that when the user is listening to audio or watching video, the microphone does not work, and the microphone electrical signal input channel can be conveniently used. If the current user is in the process of talking, audio and electrical signals are being transmitted in the microphone electrical signal input channel. Therefore, the electrical signal superposition method used in this embodiment transmits the value of whether the earplug is inserted into the earphone to the terminal, and modifies the transmission line of the microphone audio electrical signal to increase the voltage range of the transmission line. For example, the voltage range of an ordinary earphone is 0-1.8V, and the voltage range of the earphone transmission line in this embodiment is increased to 0-4V. When pressure sensing occurs on the earplug contacts, the voltage of the analog audio signal is maintained at 2V.

If the user uses a headset to talk, the voltage of the microphone transmission line changes between 0-1.8, and if the user inserts earplugs into the ear, the voltage changes between 2-3.8. Based on this, the terminal needs to reduce the collected audio electrical signal when restoring the voice Handle to prevent audio exceptions.

If the 5 sets of audio electrical signals collected in the period are all less than 2, it can be considered that the user has pulled out the earplugs, and an audio channel switching will be initiated.

Sensing data transmission module, the main function of this module is to periodically receive audio electrical signals of 5 contacts from the earphone contact sensing module (microphone input electrical signal) and convert them into XML (json) format that can be recognized by mobile phone software. Sent to the induction data processing module, the XML format of the data transmission is as follows:

[info]

<ID>1</ID>//contact identification

<signal>0<signal>//current status

<ID>2<ID>

<signal>1<signal>//Current status

…

[/info]

Based on the above components of the earphone provided in this embodiment, the following components can be set in the terminal involved in this embodiment to cooperate with the above components of the earphone to realize the audio output channel provided by the present invention switch. The terminal involved in this embodiment may specifically have the following components:

Induction data processing module: this module is mainly for the data of the earphone contact obtained from the inductive data transmission module (this module is arranged in the earphone, which will be described in the third embodiment below) (that is, the earphone contact sensor The measured pressure information) is calculated and processed. Every time the data in XML format is obtained, the module will analyze the XML data for calculation. The core of the calculation is to read the signal signal values of 5 contacts at the same time (among them, the 5 In the contact, if the contact detects pressure, the signal signal value is 1, if no pressure is detected, the signal signal value is 0), and a simple addition operation is performed, if the superimposed value of 5 signal signal data sigsum>= 3. It is considered that the earphone is inserted into the user's ear at this time point. Although the earplug part has 5 contacts, due to the user's different usage habits, if all 5 contacts are required to be signal1, the accuracy of the judgment may decrease. Therefore, when sigsum>=3, the bool type insert value of whether the defined earplug is inserted is set to true. Taking 5 sets of data as a cycle (that is, within the first preset time period mentioned above), when there are 4 true insert values in the calculated 5 sets of data, it is considered that the current user's earplugs are inserted into the ear and passed to the audio channel switch The insertdata of the module is 1, if the cumulative insert value is less than 4 true. The insertdata passed to the audio channel switching module is 0.

The current audio channel data acquisition module, this module is mainly responsible for reading the current audio channel audioway, the earphone channel is 1, and the normal channel of the mobile phone is 0.

In the audio channel switching module, the condition for switching the audio channel is to compare the values of audioway and insertdata. For example, if the audioway is 1 and the received insertdata is 1, the current audio channel will continue to be maintained. Audioway is 0 and received insertdata is 1, audio switching is performed.

The earphone provided in this embodiment can detect the wearing state of the user, and send the wearing state of the user to the terminal, so that the terminal can determine whether the earphone is currently worn by the user according to the earphone wearing state information sent by the earphone, so as to determine whether to switch the current audio output of the terminal channel, so that the terminal can automatically switch the audio output channel of the terminal according to the situation of wearing the earphone, making the audio playback of the terminal more intelligent.
