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 invention.
In view of the above problem, in the present embodiment, a mode switching method for sound reproduction is particularly proposed. The method may be implemented in dependence on a computer program which is executable on a computer system based on the von neumann architecture.
As shown in fig. 1, the mode switching method for sound playing out provided in this embodiment is applied to a sound system, where the sound system is provided with a first playing out mode and a second playing out mode, and the mode switching method for sound playing out specifically includes the following steps:
step 102: and acquiring the current environmental parameter value in a preset time period.
The first external playing mode and the second external playing mode are two preset sound external playing modes of a sound system, more specifically, the first external playing mode refers to a sound external playing mode which can be applied to public occasions, namely a sharing external playing mode, in the first external playing mode, a user and people around the user can hear external playing sound, the second external playing mode refers to a sound external playing mode which needs to pay attention to privacy or places sensitive to sound disturbance, namely a privacy external playing mode, in the second external playing mode, only the user can hear obvious external playing sound, and people around the user cannot hear the external playing sound, or the external playing sound is very small. The current environment parameter value is index data for reflecting the sensitivity of the current environment to sound, and may be one or a combination of multiple kinds of information such as vibration (intensity, frequency), brightness of ambient light, ambient sound (loudness, frequency), location (position, and location change speed), and the like of the current environment. The current environmental parameter value is obtained once every other specific time within a preset time period, which may be 5 minutes, 6 minutes, 7 minutes, or the like, and may be determined specifically according to an actual application, and is not specifically limited herein. It is understood that, by obtaining the current environmental parameter value within a preset time period, the sound play mode switching decision is made subsequently based on the current environmental parameter value.
Step 104: and determining the current environment type corresponding to the current environment parameter value through a preset environment classifier, wherein the output result of the preset environment classifier is the first environment or the second environment.
The preset environment classifier of the embodiment is used for classifying different current environment parameter values into one of a first environment and a second environment. In particular, a classifier that can be classified using at least one machine learning model. The machine learning model may be one or more of the following: neural networks (e.g., convolutional neural networks, BP neural networks, etc.), logistic regression models, support vector machines, decision trees, random forests, perceptrons, and other machine learning models. As part of the training of such a machine learning model, the training input is various environmental feature quantities, such as temperature, vibration, sound, brightness, and the like, and a relational classifier is established by training the environmental feature quantities and the environmental types. And the preset environment classifier is enabled to have the capability of judging whether the current environment type corresponding to the input current environment parameter value is the first environment or the second environment. In this embodiment, the classifier is a classifier, and two classification results, that is, the first environment or the second environment, are obtained.
For example, a branch model of the machine learning model may be added, and the environment feature amount corresponding to the first environment may be subjected to classification training, and the classification result is the first a environment, the first B environment, the first C environment, or the like, or the environment feature amount corresponding to the second environment may be subjected to classification training, and the classification result is the second a environment, the second B environment, the second C environment, or the like.

Specifically, after the current environment type corresponding to the current environment parameter value is judged to be the first environment, the sound playing mode of the sound system is set to be the sound playing mode corresponding to the first environment, namely, the first playing mode, so that automatic switching of the sound playing mode of the sound system is achieved, and the situation that a user needs to manually switch or set the sound playing mode is avoided. Under first environment, the user can carry out sound amplification with sharing amplification mode for the user can enjoy sound amplification naturally, has promoted user experience.
Step 108: and if the current environment type is the second environment, setting the sound play-out mode of the sound system to be the second play-out mode.
Specifically, after the current environment type corresponding to the current environment parameter value is judged to be the second environment, the sound playing mode of the sound generating system is set to be the sound playing mode corresponding to the second environment, namely the second playing mode, so that automatic real-time switching of the sound playing mode of the sound generating system is achieved, and convenience in switching of the sound playing mode is improved. Further, under the second environment, the user can play sound in the privacy play-out mode, so that the user can naturally enjoy the sound play-out without disturbing people around, the privacy of the user is protected, and the user experience is improved. Moreover, privacy risks caused by untimely manual switching of a user or manual random switching of the sound playing mode are avoided.
It should be noted that the first environment and the second environment in this embodiment may also be continuously divided into a plurality of first sub-environments and second sub-environments, such as a first a environment, a first B environment, a first C environment, and the like, a second a environment, a second B environment, a second C environment, and the like, and accordingly, the first play mode and the second play mode may be correspondingly divided into a first a-level play mode, a first B-level play mode, a third C-level play mode, and the like, a second a-level play mode, a second B-level play mode, a second C-level play mode, and the like. Further, the first environment and the second environment, and the first play-out mode and the second play-out mode in this embodiment are only examples, and do not serve as grounds for limiting the present application.

In this embodiment, the training sample set includes first environment and the environmental parameter value and the second environment that correspond and the environmental parameter value that corresponds, has guaranteed the comprehensiveness of training sample set, utilizes the environmental classification ware that training sample set trained out like this can learn more comprehensive accurate environmental classification rule, has improved the efficiency that the classifier was predetermine in training machine learning to can further improve the efficiency of distinguishing first environment and second environment.
The above steps 110 and 112 describe a training process of the environment classifier, and in practical applications, the environment classifier can be obtained by a plurality of training methods, as shown in fig. 3a, which is a flowchart of a possible implementation manner of the training method of the environment classifier, including:

and 112F, acquiring the training times of the preset classifier, and determining that the preset classifier is completely trained to obtain the preset environment classifier under the condition that the training times reach the maximum preset times.
Specifically, training times corresponding to a preset classifier are obtained, when the training times reach the maximum preset times, it is determined that the preset classifier is trained completely, and a parameter value used by the preset classifier for machine learning is obtained, otherwise, the obtained parameter value and a test sample set are used for continuing training the preset classifier for machine learning.
