Description

speaker

The invention relates to a loudspeaker.

The horn (or loudspeaker) is a very common sound player at present. The function of the horn is to convert the electrical signal into the mechanical vibration of the diaphragm, and then make the surrounding air change in density to produce sound for the people around to listen to. .

For some large speakers, in order to enhance the sound pressure in the low frequency range, bass reinforcement devices, such as bass reflex tubes (Bass reflex) or passive radiators (Passive Radiator), etc. are generally added to the speakers to take advantage of the phase inversion characteristics , to achieve the effect of strengthening the low frequency.

With the development of thinner and lighter speakers today, many speakers (such as smart phones, tablet computers or notebook computers, etc.) have small internal space, so most of them use micro-speakers to reduce the occupied volume and thickness. However, the speaker volume of the micro-speaker is very small, which will detract from the original output performance of the speaker.

Therefore, a number of private enterprises or related academic and research units have invested a lot of money, manpower and time in the research of speakers, and are eager to improve various characteristics of speakers.

In view of this, an object of the present invention is to provide a speaker capable of solving the above-mentioned problems, which includes a casing, a rubber speaker, a sound output unit, and a plastic fixing ring. The rubber speaker is fixed on the casing. The rubber speaker accommodates the sound unit, and the plastic fixing ring is connected between the rubber speaker and the sound unit, wherein the plastic fixing ring surrounds the sound unit, and the rubber speaker surrounds the plastic fixing ring.
