Abstract

A loudspeaker structure includes a loudspeaker unit, a cantilevered edge, and an acoustic wave element. The loudspeaker single system has at least a basin frame and a diaphragm. The acoustic wave element is composed of an inner frame and an outer shell. The frame and at least one wave plate are composed, and the overhanging edge and the elastic wave piece can be fitted together and can be set upside down, and the diaphragm is combined with the overhanging edge and the elastic wave piece below or above When the speaker unit is driven to emit sound, the diaphragm will vibrate synchronously. At this time, the vibration state of the diaphragm can be located and balanced by the elastic wave member, so that the speaker can effectively perform when subjected to high-power driving. The thinning of the ground can also prevent the diaphragm from generating unbalanced vibrations, which can cause unstable output audio.

Description

Speaker structure

The invention relates to a loudspeaker structure, in particular to a loudspeaker that can be fixed to the sound emitting surface of a speaker unit by an elastic wave element, and the unit can be thinned by the elastic wave element, and at the same time, the diaphragm can be stabilized so that it can balance vibration structure.

The conventional speaker structure is an electronic device that converts electronic signals into sound signals. After the voice coil is energized, it will mutually repel with the magnet, forming a piston-like effect. Therefore, the diaphragm in front of the magnet will be pushed forward. The sound wave in front of the diaphragm is radiated to the surroundings. In addition, a ring-shaped elastic wave is used to fix the voice coil in the structure. Since the elastic wave is placed between the magnet and the diaphragm, the volume of the speaker cannot be reduced. The size limitation cannot be applied to many thin and light electronic products.

The current scientific and technological electronic products (such as: thin TVs, notebook computers, tablet computers, PDAs, MP3 players, or mobile phones, etc.), in order to meet the overall model with thin and light features or for easy portability, its overall design The specifications and dimensions are very small, so the space for accommodating speakers is also very limited, so many flat speakers are created accordingly. And this type of smaller flat speakers is often in pursuit of thinness, so the speakers are The internal elastic wave structure is removed to make the overall structure thinner. However, when the structure is changed in this way, the distortion of the diaphragm is not easy to occur at low power output; however, at high power output, The vibration amplitude of the diaphragm is large. At this time, the diaphragm will produce unbalanced vibration and shaking, so it also makes the sound output very unstable. Therefore, the conventional thin speaker can only meet the low power output performance. High power output creates corresponding restrictions.

Therefore, if a speaker structure can be provided, an elastic wave member is fixed on the sound emitting surface of the speaker unit, so that when the speaker is driven by high power to generate vibration, it can effectively locate and balance the vibration of the diaphragm through the elastic wave member. State, so that sound can be output smoothly, should be an optimal solution.
