Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of earphone performance detection, in particular to a temperature and humidity simulation device. Background Art
[0002] Headphones are an indispensable tool for listening to audio nowadays. They can be generally divided into earplug type, ear hook type, in-ear type and head mounted type. Among them, the basic components of head mounted headphones include headband and two earmuffs with built-in speakers. When in use, the headband is worn on the head, and the two earmuffs are respectively covered on the left and right ears. This wearing method does not cause a sense of weight in the ear canal, thus greatly improving the comfort during use.
[0003] Headphones need to undergo a series of simulation tests during the research and development or production process. The existing technology only measures the acoustic performance at room temperature. During actual use by users, the headphones are covered on the ears, and due to the evaporation of human sweat, exhaust from pores, etc., there will be an impact of temperature and humidity in the real use environment. However, the tests in the existing technology do not apply the temperature and humidity of a simulated human head to the product to evaluate the impact on the product's appearance, structure, and function.

In some embodiments of the present invention, the shell is a rectangular hexahedron, and an artificial ear is installed on each of the two sides. The water tank is used to hold water, and the water in the water tank is heated by a humidity control mechanism to generate steam to increase the humidity in the internal cavity of the shell. The temperature and humidity sensor is used to sense the temperature and humidity inside the shell; and the temperature and humidity sensor is arranged near the artificial ear, and its measurement result is more realistic.

Therefore, the present invention is provided with a head-mounted support, the shape of which can simulate the top of a person's head or other shapes to play the role of supporting the headband.
[0018] More preferably, the shell includes an outer shell, a filling layer and an inner shell from the outside to the inside.
