Abstract
The utility model relates to a rear protrusion plane solid diaphragm with flat front in the flat panel loudspeaker field. The diaphragm designs the back of a plane sound board into prominent cone solid structure; selecting light hard materials to facilitating the diaphragm of loudspeakers being able to ensure the diaphragm to gain ideal rigidity, reduce the weight of the diaphragm to the less degree and greatly reduce the impact of segmentation vibration on the tone quality.
Description
Technical field
The utility model relates to the prominent type dynamic planar loudspeakers vibrating diaphragm of a kind of back of the body in loud speaker field.
Background technology
Current loud speaker is in order to obtain the high-fidelity playback, require loud speaker to make the piston vibration sounding, each parts to loud speaker propose to compare higher requirement, common loud speaker is owing to make concave surface cone vibrating diaphragm with paper or other thin material, usually in frequency response, require vibrating diaphragm light and have good rigidity, because being subjected to the restriction of material to improve rigidity must gain in weight, weight reduction certainly will influence the rigidity of vibrating diaphragm again and strengthen cuts apart generation of vibration, particularly in current panel speaker, generally all use two-sided smooth thin plate to do vibrating diaphragm, the vibrating diaphragm of this structure more is easy to generate harmful vibration of cutting apart, and more makes both poor sound quality.
Summary of the invention
The purpose of this utility model provides the outstanding plane entity vibrating diaphragm of a kind of positive flat back.
The technical scheme that its technical problem that solves the utility model adopts is: the utility model comprises voice coil loudspeaker voice coil connection hole portions, vibrating diaphragm ring coupling part, front working portion, back side tapering part, it is characterized by positive flat back and is the outstanding real core of cone-shaped; As preferred version, the utility model adopts the polyethylene foam plastics to make.
The utility model is because the version that its back side jut is similar to the triangle mechanics has been strengthened the integral rigidity of vibrating diaphragm, add with light hard material such as foamed plastic and make and reduced weight to greatest extent, lowered effectively and cut apart generation of vibration, promoted the tonequality of loud speaker.
Description of drawings
Figure one is the structural representation of the utility model one embodiment.
With reference to figure one, this vibrating diaphragm by 1., back side cone ledge, 2., the plane working portion, 3., the voice coil loudspeaker voice coil connection hole portions, 4., the ring coupling part forms.
Embodiment
With reference to figure one, the utility model execution mode is to make vibrating diaphragm ring coupling part 4. mutually bonding with ring on the basis of existing loud speaker technology, the voice coil loudspeaker voice coil connecting hole is 3. bonding with the driving voice coil loudspeaker voice coil, the former concave surface cone vibrating diaphragm that is replaced loud speaker by the outstanding plane entity vibrating diaphragm of positive flat back uses, and is assembled into plate shaped loud speaker.
Claims (2)
1. a back side is given prominence to positive smooth plane entity vibrating diaphragm, is comprised voice coil loudspeaker voice coil connection hole portions, vibrating diaphragm ring coupling part, front working portion, back side tapering part, it is characterized in that positive flat back is the outstanding real core of cone-shaped.
2. the outstanding positive smooth plane entity vibrating diaphragm in the back side according to claim 1 is characterized in that making with the polyethylene foam plastics.
