Novel theta 0.5 miniature voice coil

Technical Field

The utility model belongs to the technical field of loudspeakers, and particularly relates to a novel theta 0.5 miniature voice coil.

Background

The speaker (commonly called as a loudspeaker) is inseparable in life and work of people, and most of the speakers can not be separated as long as the speaker emits sound information by electricity, and a core component in the speaker is a voice coil, namely, the voice coil is a coil passing audio current, is an important component of an electrodynamic speaker vibration system, and can also be called as the heart of the speaker.

The performance of the voice coil affects the sound pressure frequency characteristics, sound pressure level, impedance curve, distortion, transient characteristics, speaker parameters, sound quality, etc. of the speaker, particularly the power rating and life of the speaker. Just as a fatal factor of heart disease, speaker damage often begins with the voice coil former. Traditional polyimide voice coil loudspeaker voice coil skeleton is with the polyimide film, behind the spirit high temperature resistant self-adhesive that coats with the curtain coating method to cut into the slice and coil into the cylinder again, then wind the coil, a longitudinal gap can be left to such voice coil loudspeaker voice coil skeleton, influences the performance and the life of voice coil loudspeaker voice coil.

Patent number is CN201921085020.8 a voice coil loudspeaker voice coil winding instrument and by the double voice coil loudspeaker voice coil that this instrument was made, voice coil loudspeaker voice coil winding instrument includes the coiling disk body, voice coil loudspeaker voice coil winding post, leading-out terminal and inlet wire end, wherein, voice coil loudspeaker voice coil winding post sets up in the center of coiling disk body, leading-out terminal and inlet wire end set up in the edge of coiling disk body, a serial communication port, the inlet wire end includes first inlet wire end and second inlet wire end, the leading-out terminal includes first leading-out terminal and second leading-out terminal, and first inlet wire end sets up with first leading-out terminal is adjacent, the second inlet wire end sets up with the second leading-out terminal is adjacent.

The size of the traditional voice coil is basically more than 6.0, so that the traditional voice coil is not suitable for new electronic equipment; the voice coil is too large, so that the influence on the loudspeaker is large; the size of the voice coil is reduced, but the functions cannot be compatible, and therefore a novel theta 0.5 miniature voice coil is provided.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1 to 3, the present invention provides a technical solution: the utility model provides a novel theta 0.5 miniature voice coil, including skeleton 1, the cross sectional shape of skeleton 1 sets up to circular, and skeleton 1 sets up to theta 0.5, the product that all is 0.5 more than 6.0 now does not basically, the theta 0.5 size of adoption, be favorable to using in less lighter and thinner electronic equipment, the outside of skeleton 1 is provided with coil scroll 2, the upper end outside of skeleton 1 is provided with lead wire 4, be applicable to outdoors during the use, or to the higher specific condition's of weatherability requirement application, coil scroll 2 and lead wire 4 set up the upper and lower both ends at skeleton 1 respectively, make things convenient for coil scroll 2 and lead wire 4 to install and use, arrange neatly and reduce extravagantly.

As apparent from the above description, the present invention has the following advantageous effects: the framework 1 adopts theta 0.5, so that the composite material is favorable for being applied to smaller and thinner electronic equipment and can be applied to the outdoor or the specific conditions with higher requirement on weather resistance.
