Abstract
The utility model discloses a mini resonance speak, comprising a bottom shell, an upper shell, a circuit board, a high-energy magnetic loop body, a voice coil, a balance weight and a surface cover, wherein the bottom shell is fixedly connected with the upper shell to form a resonant cavity; the high-energy magnetic loop body and the voice coil are arranged in the resonant cavity; and the weight balance is fixedly on the upper shell through the surface cover. The mini resonance speaker is characterized in that: elastic rib strip structures are uniformly distributed on the part of the bottom shell outside the central area of the bottom surface. The mini resonance speaker is simple in structure and capable of effectively improving the resonance effect of mini resonance speakers.
Description
Technical field
The utility model relates to the sound technique field, is a kind of mini resonance loudspeaker specifically.
Background technology
Common mini resonance loudspeaker generally comprise drain pan, upper casing and resonance speaker body, balancing weight and cover, and drain pan and upper casing are fixedly connected to form a resonant cavity; The resonance speaker body is installed in the resonant cavity, and balancing weight is fixed on the upper casing through cover together, and the resonance speaker body comprises that wiring board, magnetic return and voice coil loudspeaker voice coil; Voice coil loudspeaker voice coil is installed on the drain pan; When this mini resonance loudspeaker were worked, drain pan and voice coil loudspeaker voice coil contact site were difficult to produce vibrations, because the distortion of whole drain pan reaches unanimity; Therefore it is not obvious to resonate, and is difficult to reach people's needed effect.
Summary of the invention
The purpose of the utility model provides a kind of simple in structure, effectively improves the mini resonance loudspeaker of resonance effect.
The purpose of the utility model realizes through following technical scheme.
A kind of mini resonance loudspeaker; Comprise drain pan, upper casing, wiring board, high energy magnetic ex vivo, voice coil loudspeaker voice coil, balancing weight and cover; Drain pan and upper casing are fixedly connected to form a resonant cavity; High energy magnetic ex vivo and voice coil loudspeaker voice coil are installed in the resonant cavity, and balancing weight is fixed on the upper casing through cover together, it is characterized in that: the outside that is positioned at the bottom surface central region on the said drain pan is evenly equipped with the elastic bar structure.
The bottom surface central region of said drain pan is provided with the cannelure that voice coil loudspeaker voice coil is installed, and the bottom surface of voice coil loudspeaker voice coil contacts with the bottom land of cannelure, and wiring board is fixedly connected with drain pan, and the central region on the inboard shell ground of upper casing is provided with magnetic and returns installation cavity.
The utility model compared with prior art has the following advantages:
The outside that is positioned at the bottom surface central region on the utility model drain pan is evenly equipped with the elastic bar structure, and when the voice coil loudspeaker voice coil vibration, the bottom surface central region of drain pan is that the convex annular slot part is also vibrated, so can effectively improve resonance effect like this.
Description of drawings
Fig. 1 is the mini resonance loudspeaker of a utility model decomposition texture sketch map;
Fig. 2 is the drain pan structural representation of the mini resonance loudspeaker of the utility model.
Embodiment
Below in conjunction with accompanying drawing the mini resonance loudspeaker of the utility model are described in further detail.
Like Fig. 1, Fig. 2; The mini resonance loudspeaker of the utility model; Comprise drain pan 1, upper casing 2, balancing weight 3, cover 4, wiring board 6, high energy magnetic ex vivo 7 and voice coil loudspeaker voice coil 8; Drain pan 1 is fixedly connected to form a resonant cavity with upper casing 2, has guaranteed the alignment and the isometry of last lower casing, and high energy magnetic ex vivo 7 is installed in the resonant cavity with voice coil loudspeaker voice coil 8; Balancing weight 3 is fixed on the upper casing 2 through cover 4 together; The outside that on drain pan, is positioned at the bottom surface central region is uniformly distributed with and makes drain pan have suitable flexible elastic bar structure 5, between two adjacent elastic bar structures 5, forms gap 51 like this, that is to say that the bottom surface central region constitutes the bottom surface of drain pan 1 after other zone passage elastic bar structure 5 of bottom surface connects.Central region is provided with the cannelure 11 that voice coil loudspeaker voice coil is installed in the bottom surface of drain pan 1, and the bottom surface of voice coil loudspeaker voice coil 8 contacts with the bottom land of cannelure 11, and wiring board 6 is fixedly connected with drain pan 1, and the central region on the inboard shell ground of upper casing 2 is provided with magnetic and returns installation cavity.
