Method and device for determining the area of ​​the sound hole of the sound box

Abstract

The invention discloses a method and a device for determining the areas of sound out holes of a sound box, relates to the technical field of sound box designs, and aims to realize optimal sound quality for a user while meeting the ID (Industrial Design) of the sound box. According to the main technical scheme of the invention, the method comprises the following steps: receiving product data information of the sound box, wherein the product data information at least includes performance parameter information of a built-in speaker of the sound box and structure size information of the sound box;processing the product data information with a punching rate model to obtain a corresponding relationship between a sound pressure level and a punching rate, wherein the punching rate model is a pre-trained model for executing output of the corresponding relationship between the sound pressure level and the punching rate according to input product data information, and the punching rate refers tothe percentage of the areas of the sound outlet holes on the sound box and the area of a sound outlet surface; selecting a punching rate according to the obtained corresponding relationship between the sound pressure level and the punching rate; and determining the areas of the sound out holes of the sound box according to the preset area of the sound outlet surface and the selected punching rate. The method and the device are mainly used for selecting an optimal punching rate of the sound box in order to obtain the optimal areas of the sound outlet holes.

Description

technical field [0001] The invention relates to the technical field of sound box design, in particular to a method and a device for determining the area of ​​a sound hole of a sound box. Background technique [0002] A speaker is a device that can convert an audio signal into sound, and its built-in main sound-generating component is a speaker. With the continuous development of audio-visual technology, speaker manufacturers have developed a variety of audio source products, such as split, combined, desktop, and portable speakers, to meet the needs of users in different environments. For example, portable speakers are small in size and can be Portable, no need for external power supply, low power consumption, etc., it is especially favored by outdoor sports enthusiasts. [0003] At present, speaker manufacturers also apply the concept of Industrial Design (ID) to the product development process to add fashion elements to audio source products, which greatly meets the indivi...

Problems solved by technology

However, since the speaker generally radiates the sound energy converted from audio power to the space outside the speaker device through the sound outlet on its outer surface, the sound outlet will occupy the appearance area of ​​the speaker, but the appearance area of ​​the speaker is limited. Therefore, while fully displaying the ID design of the speaker on the appearance of the speaker to cater to the user's preferences, the area of ​​the sound outlet may be reduced accordingly, thereby reducing the quality of the sound effect received by the user.
