Problems solved by technology

Sound-generating devices, such as earphones and stereos, are emerging in an endless stream. However, in the prior art, most of the improvements to the sound quality of sound-generating devices focus on the improvement of their built-in speakers, while the improvement of the shell is less
But the response of the shell to the sound quality is also great, which directly affects the effect of the speaker
[0003] Taking the earphone as an example, the shell of the earphone mostly affects the sound effect of the speaker and the whole earphone due to resonance and reverberation. The shell of the earphone in the prior art is made of plastic or resin, which causes the reverberation of the sound of the earphone to be relatively long, and the sound of the shell is relatively long. The resonance is strong, and the sound effect is not clear enough, which makes the earphones have the problem of poor sound quality
In addition, plastic or resin casings have poor durability, are easily deformed, and are not light enough

Embodiment Construction

[0018] Hereinafter, the sound generating device of the embodiment of the technical solution will be described in detail with reference to the accompanying drawings.

[0019] The technical solution provides a sound emitting device, which includes a hollow housing and a speaker arranged inside the housing. The sound device can be earphones, stereos, speakers, mobile phones, notebook computers or TVs.

[0020] See figure 1 The embodiment of the present technical solution takes the earphone 10 as an example. The earphone 10 includes a hollow earphone housing and a speaker 14 arranged inside the housing. The earphone 10 may be a head-mounted type, an ear-hook type, an in-ear type, or an earplug type.

[0021] The speaker 14 can be of electric type, capacitive type, electrostatic type, pneumatic type and piezoelectric type. The speaker 14 is used to convert electrical signals into sound signals. Specifically, the speaker 14 can convert an audio electric power signal within a certain ran...

Abstract

The invention relates to an earphone which comprises a shell and a loudspeaker, wherein the loudspeaker is arranged in the shell; the shell is made of a magnesium base composite material; the magnesium base composite material comprises magnesium base metal and nano reinforcing phases which are dispersed in the magnesium base metal; and compared with an earphone which has the same shape and adopts a shell made of AZ91D magnesium alloy, the earphone reduces the total harmonic distortion by 10 percent in a frequency range of 20Hz to 50Hz.

Description

Technical field [0001] The invention relates to an earphone, in particular to an earphone using an alloy shell. Background technique [0002] With the continuous development of new technologies and new materials, people have higher and higher requirements for audio-visual quality. Sound-producing devices, such as earphones and stereos, are emerging in endlessly. However, in the prior art, the improvement of sound quality of sound-producing devices focuses more on the improvement of their built-in speakers, and there is less improvement on the casing. But the response of the shell to the sound quality is also great, which directly affects the effect of the speaker. [0003] Taking headphones as an example, their shells mostly affect the sound effect of the speakers and the entire earphone due to resonance and reverberation. The earphone shells in the prior art are made of plastic or resin, which causes the earphones to have a long reverberation. The resonance is strong, and the so...
