Abstract
The utility model discloses a loudspeaker, which comprises a bracket, a magnetic circuit system and a vibration system. The magnetic circuit system and the vibration system are both connected with the bracket. The magnetic circuit system comprises a magnetic steel, a polar plate and a magnetic cup. The magnetic steel is arranged inside the magnetic cup, and the polar plate is arranged at the upper part of the magnetic steel. The vibration system comprises a sound film and a sound coil. The sound film is combined on the sound coil. The magnetic steel, the polar plate and the magnetic cup are all square, and the bracket has a thickness of 2.9-3.2 mm. The loudspeaker provided by the utility model is thin and has good low-frequency effect and low infidelity.
Description
Technical field
The utility model relates to a kind of electronic component, especially a kind of loud speaker that is used on mobile phone or the associated electrical product.
Background technology
Loud speaker is widely used on the means of communication such as mobile phone, and along with the raising that the client requires electroacoustic performance, common loadspeaker structure and performance do not satisfy requirement of client.
The structure of common loud speaker can't satisfy the structural requirement of current ultra thin handset, and in the situation that satisfies the thin speaker requirement, its sensitivity meeting decreases, the low-frequency effect imperfection.
Summary of the invention
The purpose of this utility model is a kind of high-quality low-frequency effect, low distortion will be provided and be slim loud speaker.
The utility model realizes that the technical scheme of above-mentioned purpose is, a kind of loud speaker, comprise support, magnetic circuit system and vibrational system, described magnetic circuit system, vibrational system all with the support load, described magnetic circuit system comprises magnet steel, pole plate and magnetic bowl, be provided with magnet steel in the described magnetic bowl, pole plate is equipped with on described magnet steel top, described vibrational system comprises sound film and voice coil loudspeaker voice coil, described sound film is compounded on the voice coil loudspeaker voice coil, its improvement is: described magnet steel, pole plate and magnetic bowl are square, and described backing thickness is 2.9～3.2mm.
Described sound film is a composite membrane.
The utility model than the typical circular magnetic circuit, has higher magnetic force value and lower resonance frequency because the design magnetic structure is square, thereby reaches desirable high sensitivity value of client and low-frequency effect preferably.Reaching under high sensitivity value and the low-frequency effect situation preferably, reduce backing thickness, make it to satisfy the structural requirement of client's ultrathin mobile phone.
Description of drawings
Fig. 1 is a cutaway view of the present utility model;
Fig. 2 is a structural perspective of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is done and to be described in further detail.
