Problems solved by technology

[0002] When using a telephone, mobile phone, etc. to make a call, the user should put the earpiece on the ear to answer, or when listening to audio equipment such as MP3, the earphone earpiece should be inserted into the ear, and the volume of the earpiece is preset or manually adjusted by the user. , if the initial volume is too high, it may damage the user's hearing, if the initial volume is too low, it may not be clear
Moreover, the preset volume may not be suitable for the user in different environments. For example, in a noisy environment, the preset volume may be too low for the user to hear clearly, or in a quiet environment, the preset volume may be too low for the user to hear clearly. The volume may be too loud, causing damage to the user's hearing

Embodiment 1

[0011] Such as figure 1 As shown, Embodiment 1 of a method for automatically adjusting the volume includes:

[0012] Step 101, collecting ambient volume. During specific implementation, a microphone, which is what we usually call a microphone, may be used to collect the ambient volume, and the ambient volume signal is an analog signal.

[0013] Step 102, converting the analog signal into a digital signal. Specifically, after the analog signal is amplified and filtered by a circuit, the filtered signal is quantized and sampled to obtain a digital signal.

[0014] Step 103, judging the ambient volume according to the digital signal, and adjusting the volume of the earpiece through the audio amplifier circuit according to the ambient volume.

[0015] Wherein, the required volume of the earpiece can be determined according to the corresponding relationship between the ambient volume and the volume of the earpiece, and then the volume of the earpiece can be adjusted to the requi...

Embodiment 2

[0017] figure 2 Shown is a second embodiment of a method for automatically adjusting the volume, including:

[0018] Step 201. Generate a specific audio signal, and send the specific audio signal through the earpiece. The specific audio signal may be ultrasound with a frequency greater than 20KHz, or a general sound signal.

[0019] Step 202, collecting ambient volume. During specific implementation, a microphone may be used to collect ambient volume. The microphone can be placed near the earpiece.

[0020] During the user’s answering process, under the same volume condition of the earpiece, if the user puts the earpiece completely on the ear, the earpiece and the ear form a closed cavity, and the sound heard by the user is relatively loud; if the earpiece is far away from the ear or there is no Airtight, the sound heard by the user is relatively small. Using the solution provided in Embodiment 2, the ambient volume collected in step 202 includes not only the sound signa...

Abstract

The embodiment of the invention discloses a method for automatically regulating the volume and a device thereof, comprising: collecting the volume of the environment, wherein the volume signal of the environment is the analog signal, which is converted to the digital signal; judging the volume of the environment according to the digital signal, adjusting the volume of the headphone through the volume amplifying circuit according to the volume of the environment. Through detecting the volume of the environment, the embodiment of the invention controls and adjusts the volume of the headphone through the detected volume of the environment, which provides the proper volume under different condition for the users.

Description

technical field [0001] The present invention relates to the technical field of communications, in particular to a method and device for automatically adjusting volume. Background technique [0002] When using a telephone, mobile phone, etc. to make a call, the user should put the earpiece on the ear to answer, or when listening to audio equipment such as MP3, the earphone earpiece should be inserted into the ear, and the volume of the earpiece is preset or manually adjusted by the user. , if the initial volume is too high, it may damage the user's hearing, and if the initial volume is too low, it may not be clear. Moreover, the preset volume may not be suitable for the user in different environments. For example, in a noisy environment, the preset volume may be too low for the user to hear clearly, or in a quiet environment, the preset volume may be too low for the user to hear clearly. The volume of the audio system may be too loud, causing damage to the user's hearing. ...
