It is to be understood that the embodiments described are only a few embodiments of the present application and not all 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 application.
Referring to fig. 1, fig. 1 is a flowchart of a conference sound collecting method in an embodiment of the present application, which is applied to a battery box of a wireless headset. The wireless headset may be embodied as a bluetooth headset, such as a TWS headset, among others. Among them, TWS is called True Wireless Stereo entirely, meaning True Wireless Stereo. The TWS earphone does not have traditional physical wires, and a stereo system can be formed by the left earphone and the right earphone through Bluetooth.
The method comprises the following steps:
s101, near-end conference sound is obtained.
In this embodiment, a plurality of operation modes such as a non-conference mode and a conference mode can be set in advance for the battery pack of the wireless headset, and the current mode can be indicated by on/off, color or flashing of the mode light. The specific working mode can be switched or selected through a plurality of modes such as a function key physical key in the battery box, a touch key, voice control and the like.
It should be noted that, in this embodiment, at least 2 conference terminals of the online conference may be provided, and in this embodiment, a scheme that one of the conference terminals participates in the online conference by using a battery box of a wireless headset is described in detail, and the conference terminal is referred to as a near-end conference terminal, accordingly, conference sound of a participant at the near-end conference terminal is referred to as near-end conference sound, accordingly, other conference terminals are far-end conference terminals, and conference sound corresponding to the far-end conference terminal is far-end conference sound. The near-end and the far-end are only different from each other in the described angle, and in practical application, the far-end conference device may also participate in a specific processing scheme of conference sound collection and playing, such as described in this embodiment.
When the conference mode is entered, the battery pack can acquire near-end conference sounds.
Specifically, there are various ways for the battery box to acquire the near-end conference sound, and each of the acquisition ways will be described in detail below.
Mode 1: the near-end conference sound is collected directly by using a microphone in the battery box. Namely, a microphone in the battery box is used for collecting near-end conference sound.
Mode 2: the method comprises the steps that a wireless earphone is used for adopting near-end conference sound, namely, the near-end conference sound sent by the wireless earphone is received; the near-end conference sound is a sound signal collected by the wireless earphone.
Specifically, a microphone in the wireless headset is used for collecting sound signals at the wireless headset. Preferably, in order to reduce the energy consumption of the wireless headset, the sound playing function in the wireless headset may also be turned off, i.e. the Receiver function of the wireless headset is turned off.
Mode 3: combine wireless earphone and battery case itself to gather near-end meeting sound, concrete collection process includes:
step one, receiving earphone sound sent by a wireless earphone;
collecting sound at the battery box by using a microphone in the battery box;
and step three, carrying out audio processing on the sound at the earphone and the sound at the battery box to obtain near-end conference sound.
In this embodiment, the number of the wireless earphones is not limited, and for example, only one wireless earphone may be used to collect the sound signal at a position far away from the battery box, or a plurality of wireless earphones and microphones in the battery box may be used to form a microphone matrix.
The sound at the wireless earphone and the sound at the battery box can be simply superposed, and the sound can be weighted and superposed after being denoised (for example, the sound at the wireless earphone is amplified and then superposed).
Preferably, in view of practical application, the smaller sounds (such as the speaking of the participant) emitted by the participant need not be transmitted to the remote conference device. Based on this, the process of obtaining the near-end conference sound by performing audio processing on the sound at the earphone and the sound at the battery box may specifically include, but is not limited to, the following cases:
in the first situation, if the volume of the sound at the earphone and the volume of the sound at the battery box are both larger than a preset volume threshold, the sound at the earphone and the sound at the battery box are superposed to obtain near-end conference sound;
in the second situation, if the sound at the earphone is larger than the preset volume threshold, the sound at the earphone is taken as the near-end conference sound;
and in the third case, if the volume of the sound at the battery box is larger than the preset volume threshold, the sound at the battery box is taken as the near-end conference sound.
That is, when the volume of only one sound is greater than the preset volume threshold, the sound is regarded as a near-end conference sound; and when the volume of the two sounds is larger than the preset volume threshold, overlapping the two sounds, and taking the overlapped sound as near-end conference sound. When all the sounds are smaller than the preset volume threshold, it can be considered that no sound transmission is needed, and no near-end conference sound exists.
The preset volume threshold may be set or adjusted according to actual application requirements, and the specific size of the preset volume threshold is not limited in this embodiment.
The microphone in the battery pack may also pick up sound at the wireless headset (less volume than at the wireless headset), while the wireless headset may also pick up sound at the battery pack microphone (less volume than at the battery pack). In order to reduce the sound interference, denoising processing can be performed based on the two sound signals. Specifically, for the second case, the obtaining of the near-end conference sound may include:
step 2.1, noise reduction processing is carried out on the sound at the earphone by using the sound at the battery box;
and 2.2, taking the sound at the earphone obtained by noise reduction as near-end conference sound.
That is, if the sound at the battery pack is small, the sound at the battery pack can be used to filter a part of the sound corresponding to the sound at the battery pack collected in the sound at the earphone, so as to obtain a noiseless sound at the earphone, and the noiseless sound at the earphone can be used as the near-end conference sound.
Specifically, for case three, the obtaining of the near-end conference sound may include:
step 3.1, noise reduction processing is carried out on the sound at the battery box by utilizing the sound at the earphone;
and 3.2, taking the sound at the battery box position obtained by noise reduction as near-end conference sound.
That is, if the sound at the earphone is small, the sound at the earphone can be used to filter a part of the sound at the battery box corresponding to the sound at the earphone, which is collected from the sound at the battery box, to obtain a noiseless sound at the battery box, which is used as the near-end conference sound.
S102, sending the near-end conference sound to the near-end conference equipment so that the near-end conference equipment sends the near-end conference sound to the far-end conference equipment.
After the battery box acquires the near-end conference sound, the near-end conference sound can be sent to the near-end conference device.
The near-end conference device may be specifically a terminal device such as a mobile phone, a landline phone or a computer capable of realizing an online conference, and the embodiment does not limit the near-end conference device. Correspondingly, the far-end conference device may also be a terminal device capable of realizing an online conference, and is not limited herein.
Particularly, the near-end conference device can also participate in conference sound collection, and specifically, the sound collected by the near-end conference device can be superimposed with the near-end conference sound to obtain the final near-end conference sound.
Of course, in practical applications, the wireless headset may also directly establish a wireless communication connection with the near-end conference device, that is, the wireless headset directly transmits the collected sound at the headset to the near-end conference device.
After the near-end conference sound obtained by the near-end conference device, the near-end conference sound can be sent to the far-end conference device through the network. After the far-end conference equipment receives the near-end conference sound, the near-end conference sound can be played, so that the participants at the far-end conference equipment can clearly hear the sound of the participants at the near-end conference equipment.
The conference sound acquisition method provided by the embodiment of the application is applied to the battery box of the wireless earphone, and the battery box acquires near-end conference sound; and sending the near-end conference sound to the near-end conference equipment so that the near-end conference equipment sends the near-end conference sound to the far-end conference equipment. Namely, in the online conference process, the battery box of the wireless headset acquires near-end conference sound and then sends the near-end conference sound to the near-end conference equipment. Therefore, the conference sound which cannot be clearly collected by the near-end conference equipment can be collected by the battery box. User experience can be improved, and conference quality can be improved.
Referring to fig. 2, fig. 2 is a flowchart of a conference sound playing method in an embodiment of the present application, which is applied to a battery box of a wireless headset.

In this embodiment, there are various ways to play the far-end conference sound, which are described below:
mode 1: the battery box directly plays: namely, the loudspeaker in the battery box is used for playing the far-end conference sound. Specifically, a speaker may be directly provided in the battery pack, and then the speaker may be used to play the sound of the remote conference.
Mode 2: the wireless earphone can be used for playing, namely, the far-end conference sound is sent to the wireless earphone, so that the wireless earphone can play the far-end conference sound. Specifically, because wireless earphone also has the sound instant music, consequently, in order to avoid keeping away from the participant of battery case and can't hear far-end meeting sound clearly, also can let wireless earphone broadcast far-end meeting sound.
Mode 3: the wireless earphone and the loudspeaker in the battery box can play the far-end conference sound at the same time.
That is to say, playing the far-end conference sound specifically includes: and the loudspeaker and/or the wireless earphone in the battery box are/is used for playing the remote conference sound.
