Search Symbol (Half-width)	Description of Search Symbols
Space	"AND" indicates the intertwining of key terms used in a search
Double Quotation Marks ("") ( " " )	Double quotation marks indicate the beginning and end of a phrase, and the search will only include terms that appear in the same order of those within the quotations. Example: "image process" ： " image process "
?	Indicates a variable letter. Entering two ? will indicate two variable letters, and so on. Example: "Appl?", search results will yield apple, apply… e , appl y … ( (often used to English word searches) )
*	Indicates an unlimited number of variable letters to follow, from 1~n. Example: Enter "appl*", search results will yield apple, apples, apply, applied, application…(often used in English word searches) e , appl es , appl y , appl ied , appl ication … ( (often used to English word searches) )
AND、OR、NOT	Boolean logic combinations of key words is a skill used to expand or refine search parameters. (1) AND (1) AND: Refines search parameters (2) OR (2) OR: Expands search parameters (3) NOT: Excludes irrelevant parameters

DOI stands for Digital Object Identifier （ D igital O bject I dentifier ） ,
and is the unique identifier for objects on the internet. It can be used to create persistent link and to cite articles.

Using DOI as a persistent link

To create a persistent link, add「http://dx.doi.org/」「 http://dx.doi.org/ 」 before a DOI.
For instance, if the DOI of an article is 10.5297/ser.1201.002 , you can link persistently to the article by entering the following link in your browser: http://dx.doi.org/ 10.5297/ser.1201.002 。
The DOI link will always direct you to the most updated article page no matter how the publisher changes the document's position, avoiding errors when engaging in important research.

Cite a document with DOI

When citing references, you should also cite the DOI if the article has one. If your citation guideline does not include DOIs, you may cite the DOI link.

DOIs allow accurate citations, improve academic contents connections, and allow users to gain better experience across different platforms. Currently, there are more than 70 million DOIs registered for academic contents. If you want to understand more about DOI, please visit airiti DOI Registration （ doi.airiti.com ）。

Parallel Abstract 〈TOP〉

This research focus on testing and simulating on Microspeaker, by using frequency testing system to obtain the characteristics of Microspeaker. We received T-S parameter through impedance curve then brought parameter back to simulation of circuit model calculation therefore we can predict characteristics of Microspeaker. Due to T-S parameter is one of absolute index for deciding speaker’s characteristic therefore we can predict speaker’s performance by T-S parameter nonetheless accuracy of testing will affect reliability of T-S parameter. Getting T-S parameter must use changing volume of the sealed box to be testing conditions, due to sealed level of volume and space within speaker, those conditions will possibly affects result of T-S parameter. This research by changing testing conditions in order to understand conditions changed of T-S parameter. We are looking for appropriate results and regularity. There are two results of simulation. One is the impedance curve and the other one is frequency response. Furthermore, we will observe speaker’s characteristic tendency by adding rear volume, front volume and front vent to speaker. From what we found on result of tendency, we will follow its regularity for future Micro-Speaker development.
