Embodiment

[0023] Embodiment: The present invention effectively reduces the sound box player of standing wave, and its structural diagram is as follows figure 1 , figure 2 As shown, including the speaker, the speaker includes the front cover of the speaker and the back cover of the speaker, the front cover of the speaker and the back cover of the speaker constitute the surface of the speaker, and the surface of the speaker is an irregular whole made of several polygonal facets The facet angles between them are all greater than 145 degrees. The speaker is provided with three buttons 5 for pairing Bluetooth, volume plus and volume keys, and the three buttons are provided with meter dots. The internal structure diagram of the speaker player is as follows: figure 2 As shown, there are two speakers 2 near the front cover in the speaker, and a passive speaker 3 near the back cover in the speaker. The passive speaker is fixed on the passive speaker bracket, and the passive speaker bracket i...

Abstract

The invention discloses a sound box player capable of effectively reducing standing waves. The sound box player comprises a sound box, wherein the sound box comprises a sound box front cover and a sound box back cover, the sound box front cover and the sound box back cover form a sound box surface, two loudspeakers are arranged in positions inside the sound box near the front cover, the sound box surface is an irregular whole body formed by a plurality of polygonal prism surfaces through split joint, and an included angle between the two loudspeakers is 150 to 170 degrees. Through the design that the sound box surface is formed by the polygonal prism surfaces and the two loudspeakers are positioned on different planes, the influence on the sound waves sent out from the sound box caused by the standing waves can be effectively reduced, and meanwhile, the bass tone expression of the machine can be improved through the passive loudspeaker design. In addition, the sound box player has the advantages that the layout is ingenious, the realization is easy, the practicability is high, and the price is low.

Description

technical field [0001] The invention relates to an audio playback device, in particular to a sound box player which can effectively reduce standing waves. Background technique [0002] At present, due to design limitations, the speaker player will be interfered by standing waves when playing sound. The principle of the standing wave is that when the sound is transmitted to the surrounding obstacles through the air, the obstacles will reflect the sound wave, and the sound wave of the reflected sound of the sound of a certain frequency is just in the same vibration direction as the source sound, then the sound of this frequency will be It will be strengthened, so the sound of this frequency will become louder, and the reflected sound of some frequencies is just in the opposite vibration direction to the source sound, so the sound of this frequency will be weakened. Improper presence of standing waves in the speaker box will make the sound of the speaker more or less affect th...
