Plastic Speaker Cone History
ثبت نشده
چکیده
Paper is by far the dominant component in speaker cones. It is hard to beat cellulose paper for its mix of strength, lightness, stiffness, damping, and sound quality. Yet its strength drops off when it gets wet. The characteristics of paper cones shift due to humidity and tearing results from stress and punctures. I think almost everything has been used for speaker diaphragms, including acetic acid bacteria (Acetobacter) material, which is also used in flan recipes, and metals (e.g., magnesium, aluminum, and beryllium), but the most common alternative to paper cones are plastics.

Plastic flow potential for the cone region of the MRS–Lade model
The original formulation of the MRS–Lade model, with non–associated flow rule on the meridian plane in the cone region, has a corner. In order to reduce the computational effort of corner solution algorithms, a modified plastic flow potential for the cone part is found in the literature. This modification may have a non–admissible flip over of the flow vector in the cone–cap intersection if the...
متن کاملNovel Flexible Belt-shaped Coaxial Microcables with Tunable Multicolor Luminescence, Electrical Conduction and Magnetism
We designed a specially designed coaxial spinneret in this study. The inner stainless-steel needle was connected to the inner plastic syringe just like the traditional one. The outer stainless-steel needle was replaced by a plastic nozzle, and connected to the outer plastic syringe. The tip of the inner stainless-steel needle was shortened 2 cm from the tip of the outer plastic nozzle. This str...
متن کاملSeismic Behavior and Dissipated Plastic Energy of Performance-Based-Designed High-Rise Concrete Structures with Considering Soil–Structure Interaction Effect
Since the structure and foundation are built on soil, the soil is the major platform by which seismic vibrations are transmitted to the structure, and has noticeable effects on the response and behavior of structure during earthquakes. In this research, the recently introduced Performance-based plastic design (PBPD) and its modified Performance-based plastic design (MPBPD) method in which soil ...
متن کاملA new method of measuring plastic limit of fine materials
Index properties such as the liquid limit and plastic limit are widely used to evaluate certain geotechnical parameters of fine-grained soils. Measurement of the liquid limit is a mechanical process, and the possibility of errors occurring during measurement is not significant. However, this is not the case for plastic limit testing, despite the fact that the current method of measurement is em...
متن کاملVelocity Feedback Compensation of Electromechanical Speakers for Acoustic Applications
Electromechanical speakers are commonly used as actuators in acoustic control applications and have non-constant velocity frequency response making them poor actuators. Velocity feedback compensation designed to minimize magnitude and phase variations in speaker velocity response is developed in this work. A proportional feedback compensator acting on the error between desired velocity input an...
