Detailed ways

Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals designate the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

The audio playing method, device and electronic equipment according to the embodiments of the present invention are described below with reference to the accompanying drawings.

FIG. 1 is a flowchart of an audio playing method proposed by an embodiment of the present invention.

As shown in Figure 1, the audio playback method includes the following steps:

Step 101, when playing audio, detect the signal strength of audio signals in the audio that are lower than a preset frequency.

At present, when a user uses a mobile phone to play audio, the sound can only be transmitted to the user's ear through a speaker or connected to an earphone. The user only has an auditory experience, and cannot produce other sensory enjoyment experiences. To this end, the present application proposes an audio playback method, which utilizes the vibration generated by the bone conduction earpiece and cooperates with the auditory experience on the audio, so that the user can have a better user experience.

In an embodiment of the present invention, when playing the audio, the audio signal of the audio can be collected first, and then Fourier transform is performed on the audio signal, and then the audio signal lower than the preset frequency can be obtained. After that, the root mean square value of the signal strength of the audio signal lower than the preset frequency can be calculated, and the root mean square value can be used as the signal strength of the audio signal lower than the preset frequency.

Wherein, the audio signal may be a PCM format signal or a wav format signal.

For example: when playing music or phone ringtones, audio signals in PCM format or wav format can be collected and Fourier transformed. Then, filter out the part whose frequency is above 300hz, keep the part below 300hz. Then calculate the reserved part to obtain the root mean square value of this part of the audio signal. The calculated value is the signal strength of the audio signal whose frequency is lower than 300 Hz.

Step 102, comparing the signal strength with a preset strength.

Step 103, when the signal strength is higher than the preset strength, control the bone conduction earpiece to vibrate.

Continuing the description of the above example, if the signal strength is higher than the preset strength such as 50, the bone conduction earpiece can be controlled to vibrate.

Step 104, when the signal strength is lower than the preset strength, control the bone conduction earpiece not to vibrate.

Continuing the description of the above example, if the signal strength is lower than the preset strength such as 50, it means that the audio signal is very weak, and there is no need to control the bone conduction earpiece to vibrate.

In addition, the vibration strength of the bone conduction earpiece can be determined according to the signal strength.

Specifically, when the signal strength is higher than the preset strength, the vibration strength of the bone conduction earpiece is proportional to the signal strength. That is, the stronger the signal strength, the stronger the vibration intensity; the weaker the signal strength, the weaker the vibration intensity.

Of course, the audio signal lower than the preset frequency such as 300 Hz can also be directly driven through the receiver driving circuit to directly drive the bone conduction earpiece to vibrate.

The vibration of the bone conduction earpiece is integrated into the playback of music or ringtones. During the playback process, the stronger the audio signal below 300hz, the stronger the vibration of the bone conduction earpiece, which enriches the user experience, not just Limited to auditory experience, to meet the higher needs of users.

In another embodiment of the present invention, as shown in Figure 2, the audio playback method also includes:

Step 105, before playing the audio, it is determined that the vibration function of the bone conduction earpiece is enabled; and/or it is determined that the application APP supports the vibration function of the bone conduction earpiece.

For example, if a music playback app supports the vibration function of the bone conduction earpiece, and the bone conduction earpiece vibration function in the mobile phone is also turned on at the same time, then when playing music, the bone conduction earpiece can be used to vibrate to achieve a more dynamic experience. Play experience.

In the audio playing method of the embodiment of the present invention, when playing audio, the signal strength of the audio signal lower than the preset frequency in the audio is detected, and the signal strength is compared with the preset strength, and when the signal strength is higher than the preset strength, Control the bone conduction earpiece to vibrate. When the signal strength is lower than the preset strength, control the bone conduction earpiece not to vibrate. By integrating the vibration of the bone conduction earpiece into the playback of music or ringtones, it enriches the user experience and satisfies the higher requirements of users. demand.

The first control module 330 is configured to control the bone conduction earpiece to vibrate when the signal strength is higher than a preset strength.

The second control module 340 is configured to control the bone conduction earpiece not to vibrate when the signal strength is lower than a preset strength.

As shown in FIG. 4 , the audio playback device in this embodiment of the present invention may further include a first determining module 350 .

The first determination module 350 is configured to determine the vibration intensity of the bone conduction earpiece according to the signal intensity.

When the signal strength is higher than the preset strength, the vibration strength of the bone conduction earpiece is proportional to the signal strength. That is, the stronger the signal strength, the stronger the vibration intensity; the weaker the signal strength, the weaker the vibration intensity.

As shown in FIG. 5 , the audio playback device in this embodiment of the present invention may further include a second determining module 360 .

The second determination module 360 is configured to determine that the vibration function of the bone conduction earpiece is enabled before playing the audio, and/or determine that the application APP supports the vibration function of the bone conduction earpiece.
