Abstract
A terminal speaker includes an enclosure with accommodating space with an affixed sound production monomer. The sound production monomer has a diaphragm configured to vibrate to produce sound. The enclosure includes a first inner bottom wall and an inner sidewall fastened to the first inner bottom wall. The diaphragm is fastened to the inner sidewall, dividing the accommodating space into front and rear cavities. The first inner bottom wall is in the front cavity. A sound outlet hole penetrates the inner sidewall. The front cavity is in communication with the sound outlet hole by a front cavity channel. The diaphragm is tilted relative to the first inner bottom wall. The perimeter of the end of the front cavity in communication with the sound outlet hole is greater than the perimeter of the end of the front cavity remote from the sound outlet hole.
