speaker

Abstract

The invention discloses a loudspeaker, which comprises a shell, a vibration system and a magnetic circuit system, and is characterized in that the vibration system comprises a diaphragm and a voice coil for driving the diaphragm to vibrate; the magnetic circuit system comprises a magnet yoke, and a central magnetic circuit structure and a side magnetic circuit structure which are arranged above the magnet yoke; a gap is formed between the shell and the side magnetic circuit structure, the loudspeaker further comprises an elastic supporting piece which is fixed on the shell and is positioned below the diaphragm, a conductive framework which is conducted with an external circuit is connected between the diaphragm and the elastic supporting piece, the conductive framework comprises a side wall which is arranged between the diaphragm and the elastic supporting piece, and the side wall is positioned in the gap; the elastic supporting piece comprises a balance diaphragm, one end of the balance diaphragm is connected with the conductive framework, and the other end of the balance diaphragm is connected with the diaphragm to form an integrated structure and is fixed with the shell. According to the loudspeaker, the diaphragm and the balance diaphragm are connected into an integrated structure, the diaphragm and the balance diaphragm can be independently positioned at a time in the assembling process, the technological process is simplified, and the concentricity of the balance diaphragm is easy to control in the assembling process.

Description

technical field [0001] The invention relates to the technical field of acoustic devices, in particular to a loudspeaker. Background technique [0002] A speaker is a transducer device that converts electrical signals into acoustic signals, and has been widely used in electronic products such as mobile phones, computers, and earphones. Micro speakers are usually composed of a vibration system, a magnetic circuit system and a support system. The vibration system includes an upper vibration system and a lower vibration system. The upper vibration system includes a voice coil and a diaphragm. The upper and lower vibrating systems are respectively arranged on the upper and lower parts of the product structure. Among them, the diaphragm, the balance diaphragm and two separate materials need to be positioned separately during the assembly process, the process is complicated, and it is difficult to control the concentricity of the balance diaphragm during the bonding process. Con...
