Electronic equipment and loudspeaker thereof

Abstract

The invention discloses a loudspeaker of electronic equipment. The loudspeaker comprises a hollow frame (1) connected with the electronic equipment, a vibrating device for vibrating and producing sound, a voice coil (2) for driving the vibrating device to move, and a magnetic circuit (3) having magnetic property installed at the lower end in the hollow frame (1), wherein an end face opening is installed at the upper end of the hollow frame (1); the vibrating device covers the end face opening; one end of the voice coil (2) is connected with the vibrating device, while the other end can enter a slit of the magnetic circuit (3) and repeatedly move; the vibrating device comprises a vibrating diaphragm and a globe roof (4) fixedly installed in the middle of the vibrating diaphragm; an outer edge of the vibrating diaphragm is connected with an outer edge of the end face opening; the vibrating diaphragm is a single elastic diaphragm. The loudspeaker can output the voice frequencies having lower distortions at large power and at high volume. The invention further discloses electronic equipment comprising the loudspeaker.

Description

technical field [0001] The invention relates to the field of audio output, in particular to a loudspeaker of electronic equipment. In addition, the present invention also relates to an electronic device including the above speaker. Background technique [0002] With the wide application of electronic devices such as mobile phones and tablet computers, and because the volume of electronic devices is getting smaller and smaller, there are also higher and higher requirements for the speakers used in conjunction with them. As the installation space left for the speakers becomes smaller, but the requirements for sound quality are constantly improving, the speakers are required to have the characteristics of small size, high volume, low distortion, high power, and the ability to work at large amplitudes. [0003] In the existing loudspeaker, generally, a dome is installed on the diaphragm to form a vibrating device, and the vibrating device is driven by the voice coil to reciproc...

AI Technical Summary

Problems solved by technology

Due to the need for multi-layer thin film compounding, and based on the nature of the material itself, the thickness of the diaphragm is relatively thin, so that the diaphragm composed of multiple thin film materials has a small elastic linear range during vibration, which is easy to produce Unbalanced vibration, low reliability, and exceeding the linear stretch range at large amplitudes, resulting in high distortion, which in turn affects the quality of audio output, and cannot be used for audio output that requires high power and high volume
