Antistatic dustproof cell phone horn

Abstract

The invention discloses an antistatic dustproof cell phone horn comprising an antistatic loop, a support, an outer cover, a sound collecting cylinder, magnets, yokes, a pedestal equipped with grooves, and a vertical column. The vertical column is disposed on the center of the pedestal equipped with the grooves. The pedestal equipped with the grooves and the vertical column are integrally formed. The yokes are disposed on the two side grooves of the pedestal equipped with the grooves. The magnets are disposed over the yokes. An inner pressure sheet is arranged over the magnets. A vibrating diaphragm is arranged over the inner pressure sheet. The antistatic loop sleeves the outer side of the vibrating diaphragm. The vibrating diaphragm is arranged in the sound collecting cylinder. The sound collecting cylinder in a basin stand shape is disposed over the outer sides of the yokes. The top of the sound collecting cylinder is provided with an outwardly-bent edge. A dustproof diaphragm is disposed over the sound collecting cylinder. An outer pressure sheet is disposed over the dustproof diaphragm. The dustproof diaphragm and the outer pressure sheet successively press the bent edge of the sound collecting cylinder. The bent edge is pressed on the top end face of the support. The outer side of the support is provided with an outer cover buckled on the periphery of the support.

Description

technical field [0001] The invention relates to the technical field of speakers, in particular to an antistatic and dustproof mobile phone speaker. Background technique [0002] Radio communication devices, such as radio walkie-talkies or wireless telephones, are indispensable electronic products for modern people, especially mobile phones, which are currently very popular electronic communication devices. Generally speaking, a mobile phone uses a speaker to convert the received radio signal into an electronic signal with a frequency in the audio frequency range, and converts the electronic signal into sound through the speaker. The radio wave signal is converted from sound waves into radio wave signals by the transmitting party, and transmitted to the receiver through the transmitter. And this wireless mobile phone usually utilizes a loudspeaker as a receiver to convert the user's voice into an electronic signal, and convert it into an electric wave signal for transmission...
