Music streaming from one's laptop. Loud and clear DING alerts smartwatch users to new texts. BEEP, BEEP, BEEP: The phone's alarm wakes up its owner. Consumers expect great sound regardless of device size. As the size of electronic products continues to shrink, the importance of well-designed micro speakers is increasing. Simulation software can help you design the smallest miniature speakers with excellent sound quality.
Mikrodinamiklarni loyihalashdagi qiyinchiliklar
Planshetlar va smartfonlar yordamida iste'molchilar istalgan vaqtda va istalgan joyda striming xizmatlari, musiqa ilovalari va podkastlarni tinglashlari mumkin. Bundan tashqari, 2019 yil holatiga ko'ra, video global mobil ma'lumotlar trafigining taxminan 78 foizini tashkil etdi. Odamlar har doim eng yaxshi ovoz sifatini kutishadi, hatto ularning qurilmalari kichikroq va portativ bo'lib qolsa ham. Ajoyib ovoz sifati ehtiyotkorlik bilan tanlangan va{2}}yaxshi ishlab chiqilgan mitti dinamiklardan keladi.
The tiny frames of tiny speakers make them a design challenge. Luxurious and loud audio isn't easy for any speaker, especially one of this size. When faced with too extreme sound pressure levels (SPL), the delicate diaphragm can even crack, causing the speaker to pop. In addition to considering the fragile diaphragm, acoustic engineers also need to design a design that avoids melting the voice coil and diaphragm due to excessive current flow.
Simulyatsiya dasturiy ta'minotidan foydalangan holda, muhandislar mikrodinamik dizaynlarini ishlab chiqish tsikli davomida bir necha marta sinab ko'rishlari va yaxshilashlari mumkin, bu jismoniy prototiplarga bo'lgan ehtiyojni sezilarli darajada kamaytiradi va jarayonda vaqt va pulni tejaydi. Ushbu virtual dizayn halqasining an'anaviy jismoniy prototiplash va sinovdan yana bir afzalligi shundaki, simulyatsiya mikrodinamiklarning ishlashiga nima olib kelishini chuqurroq tushunish imkonini beradi. Simulyatsiya modellari ko'plab qimmatli ma'lumotlarni yaratadi, ularni jismoniy sinovlar orqali olish mumkin emas, chunki har qanday kattalikni modelning istalgan joyida har qanday chastotada o'lchash mumkin.
Below, we compare the characteristics of an Ole Wolff microspeaker to a loudspeaker simulation using the COMSOL Multiphysics® software and an additional Acoustics Module.

Modelga umumiy nuqtai
OWS-1943-8CP Micro Speaker Ole Wolff tomonidan ishlab chiqarilmagan miniatyura dinamikidir va bir nechta turli qismlardan iborat, jumladan:
diafragma
ovozli lasan
magnit
qutb bo'lagi
Ger
orqa shamollatish
Due to its size, the layout of the miniature speakers differs from that of conventional speakers. For example, diaphragms often function as both dust caps and spider webs. They're also pretty small: the tiny speakers modeled here measure about 19mm in diameter and 2.8mm tall, which is smaller than a penny!
