Abstract

The invention discloses an electric hair drier, and belongs to the field of household appliances. The electric hair drier comprises an electric hair drier body and a handle, wherein the two ends of the electric hair drier body are provided with an air inlet and an air outlet respectively, the air inlet and the air outlet are provided with sound quality regulating devices respectively, and each sound quality regulating device comprises a shell body matched with the shape of the electric hair drier body and a sound production assembly arranged in the corresponding shell body; the two ends of each shell body are provided with sealing plates, the inner portion of each shell body is provided with a spiral airflow channel in the axial direction of the shell body, each sound production assembly comprises a microcontroller comprising a storage module and a micro speaker arranged in an outlet of the corresponding spiral airflow channel, and sound files are pre-stored in the storage modules. Combined with the noise elimination design of the spiral airflow channels, the loudness of the noise of the electric hair drier is reduced, according to the used air volume gear of the electric hair drier, the preset sound files are played automatically through the sound production assemblies, the time-frequency characteristics of the noise of the electric hair drier are regulated, the sound comfortlevel is improved, and the sound quality of the electric hair drier is improved.

Description

technical field [0001] The invention relates to the field of household appliances, in particular to a hair dryer equipped with a sound quality control device. Background technique [0002] Electromechanical products will produce sound during use, and the sound quality of products can be evaluated by acoustic comfort. The sound generated when the hair dryer is in use includes airflow noise, mechanical rotation noise, motor electromagnetic noise, and secondary noise radiated by shell vibration, among which airflow noise and mechanical noise are the main noise sources. [0003] Aiming at airflow noise, the current Chinese patent document with the notification number CN205180660U discloses an air inlet structure of a hair dryer, and at the same time discloses a hair dryer including the air inlet structure. The air inlet structure includes a main air inlet and an auxiliary air inlet. The main air inlet is arranged at the tail of the hair dryer casing, and the auxiliary air inlet...
