Abstract
The utility model discloses a double-sided acoustic radiation loudspeaker and relates to loudspeaker structures. A front vibration diaphragm (1) and a rear vibration diaphragm (2) are arranged in opposite directions coaxially and connected via a coil (5) and are symmetrical to each other; suspension edges (3, 4) are connected to ends of the front vibration diaphragm (1) and the rear vibration diaphragm (2) and serve as a suspension system; and magnets (7, 8) and a concentrating flux plate (6) form symmetrical magnetic fields. The double-sided acoustic radiation loudspeaker has the following advantages: firstly, the vibration, suspension and magnetic circuit systems are fully symmetrical in structure, so that consistent acoustic radiation can be generated and the audition position of a sweet spot is widened; secondly, the suspension system of the loudspeaker is disposed at two ends of the vibration system and achieves a better support effect with long moment, so that the coil is prevented from tilting and rubbing a magnetic circuit during vibration; and thirdly, after the loudspeaker is installed in a loudspeaker box, acoustic radiation is formed on the front and back sides, so that the loudspeaker is free from influence of air load in the box body, the dimension can be smaller, and the design of the box body can be freer.
Description
Technical field
The utility model relates to loadspeaker structure.
Background technology
Traditional loud speaker is by single vibrating diaphragm radiation sound, and directive property is poor, especially in the medium-high frequency section. and be subjected to the casing reaction to cause harmonic frequency of loudspeakers to raise behind the audio amplifier of packing into, and the LF-response variation.
Summary of the invention
The purpose of this utility model is to provide a kind of two-sided acoustic radiation pattern loud speaker.
Vibrating diaphragm (1) and rear vibrating diaphragm (2) before the symmetry that coaxial reverse setting is connected by coil (5); Front vibrating diaphragm (1) be connected the end of vibrating diaphragm (2) and connect outstanding limit (3,4) as suspension system; Magnetite (7,8) and magnetic conductive board (6) are set form symmetric magnetic field.
Its advantage of the utility model is:
1, loudspeaker vibration, suspention and magnetic circuit system are full symmetrical configuration, can produce self-consistentency
Acoustic radiation. widen ＂ emperor position ＂ LisPos.
2, the loud speaker suspension system is positioned at the vibrational system two ends, and long moment provides better support effect
Really, prevent coil in the crooked friction of when vibration to magnetic circuit.
3, loud speaker is packed into behind the audio amplifier, and front and back are two-sided all acoustic radiation, can not be subjected in the casing empty
The gas load effect, volume can be less, and cabinet design is liberalization more.
Description of drawings:
Accompanying drawing 1 is main pseudosection of the present utility model.
Embodiment:
Vibrating diaphragm (1) and rear vibrating diaphragm (2) before the symmetry that coaxial reverse setting is connected by coil (5).
Coaxial reverse two Zhang Zhen's films are connected by same speech coil framework, and are driven in symmetric magnetic field by same coil (5). front vibrating diaphragm (1) be connected the end of vibrating diaphragm (2) and connect outstanding two ends, limit (3,4) as suspension system; Magnetite (7,8) and magnetic conductive board (6) are set form symmetric magnetic field.
The utility model has improved conventional loudspeakers directive property problem by coaxial reverse two Zhang Zhen's film radiation sound.
Claims (1)
1. a two-sided acoustic radiation pattern loud speaker is characterized in that: vibrating diaphragm (1) and rear vibrating diaphragm (2) before the symmetry that coaxial reverse setting is connected by coil (5); Front vibrating diaphragm (1) be connected the end of vibrating diaphragm (2) and connect outstanding limit (3,4) as suspension system; Magnetite (7,8) and magnetic conductive board (6) are set form symmetric magnetic field.
