Problems solved by technology

[0002] At present, wearable products on the market, including smart watches and smart bracelets, usually only have the external speaker mode, which makes it easy for the user to use the wearable product to play music or the sound of a call, and the sound is easily heard by the surrounding People eavesdrop, so it is difficult to achieve the effect of anti-eavesdropping
In practical applications, in order to prevent the played sound from being eavesdropped by the surrounding people as much as possible, users usually need to figure 1 In this way, the wearable product is closely attached to the ear for listening, but this method still has the risk of the call being eavesdropped by the people around; It will bring great inconvenience to listening when it is attached to the ear; further, when the user puts the wearable product close to the ear, he can only hear the mono sound, and cannot obtain the stereo effect

Embodiment 1

[0084] see figure 2 , figure 2 It is a schematic flowchart of an audio signal processing method disclosed in an embodiment of the present invention. Such as figure 2 As shown, the audio signal processing method may include the following steps:

[0085] 201. The first wearable device divides an audio signal to be played by the first wearable device into a left channel signal and a right channel signal.

[0086]In the embodiment of the present invention, the first wearable device may include wearable products including smart watches and smart bracelets, which is not limited in the embodiment of the present invention.

[0087] In the embodiment of the present invention, the audio signal to be played by the first wearable device may include a music audio signal to be played by the first wearable device, for example, the first wearable device may divide the singing sound included in the music audio signal to be played The audio signal to be played by the first wearable devic...

Embodiment 2

[0098] see Figure 4 , Figure 4 It is a schematic flowchart of another audio signal processing method disclosed in the embodiment of the present invention. Such as Figure 4 As shown, the audio signal processing method may include the following steps:

[0099] 401. The first wearable device detects whether the first wearable device is in a wearing state, and if yes, execute step 402; if no, end this process.

[0100] As an optional implementation manner, in the above step 402, the detection by the first wearable device of whether the first wearable device is in the worn state may include:

[0101] The first wearable device detects the distance value between the bottom of the first wearable device and an external obstacle through an infrared detection module located at the bottom of the first wearable device;

[0102] And, the first wearable device judges whether the distance value between the bottom of the first wearable device and the external obstacle is less than or eq...

Embodiment 3

[0131] see Figure 5 , Figure 5 It is a schematic structural diagram of an audio signal processing device disclosed in an embodiment of the present invention. Such as Figure 5 As shown, the audio signal processing device may include:

[0132] A sound division unit 501, configured to divide the audio signal to be played by the first wearable device into a left channel signal and a right channel signal;

[0133] The control unit 502 is configured to control the bone conduction module in the first wearable device to convert the left sound channel signal into a first vibration signal and transmit it through the bone medium;

[0134] The transmission unit 503 is configured to transmit the right channel signal to a second wearable device communicatively connected to the first wearable device, so that the second wearable device controls bone in the second wearable device. The conduction module converts the right sound channel signal into a second vibration signal and transmits ...

Abstract

The embodiment of the invention relates to the field of audio signal processing, and discloses an audio signal processing method, device and system. The method comprises the following steps of: dividing an audio signal to be played by first wearable equipment into a left channel signal and a right channel signal; controlling a bone conduction module in the first wearable equipment to convert the left channel signal into a first vibration signal and transmit the first vibration signal through a bone medium; and, transmitting the right channel signal into second wearable equipment in communication connection with the first wearable equipment, so that the second wearable equipment controls the bone conduction module in the second wearable equipment to convert the right channel signal into a second vibration signal and transmit the second vibration signal through the bone medium. By means of the embodiment of the invention, sound can be listened conveniently; the risk that sound is eavesdropped by people around can be reduced; and the stereophonic effect is obtained.
