TW201916699A - Speaker structure capable of avoiding occurrence of unstable audio output caused by unbalanced vibration of the diaphragm - Google Patents

Abstract

A speaker structure includes a speaker unit, an edge and a damper. The speaker unit at least has a basin and a diaphragm. The damper is composed of an inner frame body, an outer frame body and at least one wave piece. The edge and the damper can be fitted to each other and disposed upside down. The diaphragm is coupled to a lower side or upper side of the edge and the damper. When the speaker unit is driven to emit sound, the diaphragm will vibrate synchronously. In the meantime, the damper can be used to position and balance the vibration state of the diaphragm, such that when the speaker is subjected to high power driving, the speaker unit can be effectively thinned and occurrence of unstable audio output caused by unbalanced vibration of the diaphragm can be avoided.

Description

Speaker structure

The invention relates to a speaker structure, in particular to a speaker which can be fixed on a sound emitting surface of a speaker unit by an elastic wave member, and which can thin the single body by the elastic wave member and at the same time stabilize the diaphragm to balance the vibration. structure.

The conventional speaker structure is an electronic device for converting an electronic signal into an audio signal, which mainly generates a mutual repulsive relationship with the magnet after the voice coil is energized, and forms a piston-like action, thereby pushing the diaphragm in front of the magnet. The sound wave in front of the diaphragm radiates to the periphery. In addition, a ring-shaped elastic wave is used to fix the voice coil. Since the elastic wave is disposed between the magnet and the diaphragm, the speaker cannot be reduced in size because The limitation of volume cannot be applied to many electronic products that are light and thin.

The current technology-based electronic products (such as thin TVs, notebooks, tablets, PDAs, MP3 players, or mobile phones) are designed to meet the overall slimness of the model or to be easy to carry. The specifications and sizes are very small, and the space for accommodating the speakers is very limited. Therefore, many flat-panel speakers are produced. This type of smaller-sized flat-panel speakers tends to be light and thin, so the speakers will be used. The internal elastic wave structure is removed to make the overall structure thinner, but the practice of changing the structure is such that, at low power output, since the vibration amplitude of the diaphragm is not large, distortion is not easily generated; but at the time of high power output, The vibration amplitude of the diaphragm is large, and the diaphragm will generate unbalanced vibration and shaking, which also makes the output of the sound very unstable. Therefore, the conventional thin speaker can only meet the low power output performance. High power output produces a corresponding limit.

Therefore, if a speaker structure can be provided, a ballistic member is fixed on the sound emitting surface of the speaker unit, so that the speaker can be effectively positioned and balance the vibration of the diaphragm through the high-power driving vibration. The state that allows the sound to output smoothly should be an optimal solution.
