Abstract

The invention provides a portable sound box, and belongs to the technical field of machinery. The portable sound box comprises a box, a baffle, and a screen. The box is made of an aluminum alloy. The appearance of the sound box is beautiful. Furthermore, the sound box is provided with a first handle and a second handle, and thus the sound box is convenient to carry and deliver. Due to the phase reversal hole, the low pitch sound effect of the sound box is good, and at the same time, the noise is avoided. The provided screen can protect the loudspeaker and is capable of preventing dusts entering the sound box. The box is made of alumina alloy, and the mechanical performance and service life of the box are both improved therefore.

Description

technical field [0001] The invention belongs to the technical field of machinery and relates to a portable sound box. Background technique [0002] The speaker is the terminal of the entire audio system and an extremely important part of the audio system. Its function is to convert audio power into corresponding sound energy and radiate it into the space. With the development of audio-visual technology, audio source products show a trend of diversification, and various types such as split type, combined type, desktop, and portable have appeared for different users and different usage environments. [0003] The pace of life is accelerating, and busy work brings a lot of pressure to life. Listening to music is one of the best ways to relieve stress. However, due to environmental constraints, listening to music has become a luxury for people who often go out to work. In this market context, portable speakers were born. [0004] The portable speaker can be carried with you, do...
