Background technique:
As digital audio and video signals handle the continuous development with audio content transmission technology, in consumer electronics product,
Audio-frequency function is being played a greater and greater role.For some non-dedicated audio-frequence player devices, such as smart phone, notes
This computer, tablet computer etc., the compact that these equipment need to do is light, because, and do not have enough spaces to hold
Receive independent high-fidelity loudspeaker, for above equipment, the loudspeaker of installation needs to have opposite high-fidelity loudspeaker
Thinner, light, small and exquisite loudspeaker.
Utility model content:
The purpose of this utility model provides a kind of miniature loudspeaker aiming at the deficiencies in the prior art, can
The use for meeting the non-dedicated audio-frequence player device such as smart phone also has more light on the basis of meeting loud-speaking function
Small and exquisite shape.
The technology solution of the utility model is as follows:
A kind of miniature loudspeaker comprising external frame, external frame are hollow structure, and loudspeaker assembly is mounted on outer
The inside of portion's frame, the side of external frame are provided with the acoustical ports of output sound outward；Loudspeaker assembly includes magnet group
Part, audio radiation surfaces and voice coil, magnet assembly are fixedly mounted on the inside of external frame, and audio radiation surfaces can by suspension element
Movably it is suspended on magnet assembly；Magnetic flux gap, the side that voice coil passes through chemical bonding or mechanical connection are formed on magnet assembly
Formula is attached to the bottom surface of audio radiation surfaces, and a part of voice coil is inserted into magnetic flux gap.
Further, external frame with a thickness of 8.5mm to 10mm, external frame is adopted made of plastic.
Further, the field drives voice coil of magnet assembly moves up and down, and voice coil drives audio radiation surfaces relative to magnet group
Part generates sound wave in a manner of vibrating.
Further, the upper surface of suspension element and the bottom surface of audio radiation surfaces connect, the lower surface of suspension element and magnet
The upper surface of component connects.
Further, suspension element is located in the area of coverage of audio radiation surfaces.
Further, suspension element extends vertically between audio radiation surfaces and magnet assembly.
Further, suspension element is made of elastic material, and elastic material is silicone resin, rubber or gel rubber material.
The utility model has the beneficial effects that: since acoustical ports are located at the side of external frame, enable loudspeaker
Enough that sound occurs outward from side, i.e. sound is exported on loudspeaker is lateral, can be effectively reduced the thickness of loudspeaker,
The thickness of loudspeaker can be made to be in the range of 8.5mm to 10mm.
Detailed description of the invention:
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the structural schematic diagram of utility model works state.
Specific embodiment:
It is right with reference to the accompanying drawing in order to keep the above objects, features, and advantages of the utility model more obvious and easy to understand
Specific embodiment of the present utility model is described in detail.
As shown in Figs. 1-2, a kind of miniature loudspeaker comprising external frame 102, external frame 102 are hollow structure,
Loudspeaker assembly is mounted on the inside of external frame 102, and the side of external frame 102 is provided with the acoustics end of output sound outward
Mouth 120；Loudspeaker assembly includes magnet assembly 104, audio radiation surfaces 106 and voice coil 108, and magnet assembly 104 is fixedly mounted on
The inside of external frame 102, audio radiation surfaces 106 are movably suspended on magnet assembly 104 by suspension element 112；Magnetic
Magnetic flux gap 118 is formed on body component 104, voice coil 108 is attached to acoustically radiating firing table by way of being chemically bonded or being mechanically connected
A part of the bottom surface 116 in face 106, voice coil 108 is inserted into magnetic flux gap 118.
Since acoustical ports 120 are located at the side of external frame, enable loudspeaker that sound occurs outward from side, i.e.,
Sound is exported on loudspeaker lateral (direction shown in arrow 130 in Fig. 1), can be effectively reduced the thickness of loudspeaker
Degree, can be such that the thickness of loudspeaker is in the range of 8.5mm to 10mm.
External frame 102 with a thickness of 8.5mm to 10mm, external frame 102 is adopted made of plastic.
Wherein, the field drives voice coil 108 of magnet assembly 104 moves up and down, and voice coil 108 drives 106 phase of audio radiation surfaces
Sound wave is generated in a manner of vibration for magnet assembly 104.
Wherein, the upper surface 132 of suspension element 112 is connect with the bottom surface 116 of audio radiation surfaces 106, suspension element 112
Lower surface 134 is connect with the upper surface of magnet assembly 104.
Suspension element 112 is located in the area of coverage of audio radiation surfaces 106.
