Embodiment 1

[0047] An embodiment of the present invention provides a method for playing audio, which is applied to electronic equipment equipped with a hard disk and an audio output device, such as figure 1 As shown, the method may include the following processing flow:

[0048] Step 101, acquire audio data frames to be played.

[0049] Step 102: Decrease the volume value of the audio data corresponding to the pre-stored interference frequency point in the audio data frame, to obtain the audio data frame after volume reduction processing.

[0050] Step 103, perform audio playback according to the audio data frame after volume reduction processing.

[0051] In the embodiment of the present invention, when an electronic device equipped with a hard disk and an audio output device performs audio playback, the volume value of the audio data corresponding to the pre-stored interference frequency point in the audio data frame to be played is reduced, and the volume value after the volume reduct...

Embodiment 2

[0053] The embodiment of the present invention provides a method for playing audio, which is applied to electronic equipment equipped with a hard disk and an audio output device, such as portable electronic equipment such as a notebook computer. The hard disk here may specifically refer to a mechanical hard disk (or non-solid state hard disk). ). The method is preferably executed by an audio processing chip (such as a processing chip of a sound card) or a CPU (Central Processing Unit, central processing unit) of the electronic device.

[0054] The following will be combined with specific implementation methods to figure 1 The processing flow shown will be described in detail, and the specific content may be as follows.

[0055] Step 101, acquire audio data frames to be played.

[0056]Wherein, an audio data frame is a basic data unit of audio playback, and each audio data frame is used to record audio data played in a time slot. For example, an MP3 (an audio format) file is...

Embodiment 3

[0083] An embodiment of the present invention provides an audio playback device, which is applied to electronic equipment equipped with a hard disk and an audio output device, such as Figure 4 As shown, the device includes:

[0084] Obtaining module 410, for obtaining the audio data frame to be played;

[0085] The processing module 420 is used to reduce the volume value of the audio data corresponding to the pre-stored interference frequency point in the audio data frame, and obtain the audio data frame after volume reduction processing;

[0086] The playback module 430 is configured to perform audio playback according to the audio data frame after the volume reduction processing.

[0087] Preferably, the processing module 420 is specifically used for:

[0088] If the hard disk of the electronic device is performing data transmission, then reduce the volume value of the audio data corresponding to the pre-stored interference frequency point in the audio data frame, and obt...

Abstract

The invention discloses an audio frequency playing method and device, and belongs to the computer technical field; the method is applied in electronic equipment having a hard disk and an audio frequency output device; the method comprises the following steps: obtaining audio frequency data frames to be played; reducing volume value of audio frequency data corresponding to a pre-stored interference frequency point in the audio frequency data frames, thus obtaining the audio frequency data frames after volume reduction process; playing the audio frequency according to the audio frequency data frames after the volume reduction process. The method and device can improve work stability of the hard disk in the electronic equipment.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to an audio playing method and device. Background technique [0002] With the continuous development of hard disk technology, the hard disk has become a very important data storage device in electronic equipment. In the application process of electronic equipment, the stability of hard disk work is a very important performance index. The core work of the hard disk is to store and transmit data, so the stability of the hard disk can be directly reflected in the stability of the data transmission rate. [0003] In the process of realizing the present invention, the inventor finds that there are at least the following problems in the prior art: [0004] When an audio output device (such as a speaker) in an electronic device performs audio output, it will vibrate, which will cause the hard disk to vibrate accordingly. Especially portable electronic devices such as notebook computers...
