How to calculate speaker size
Size is a crucial factor when buying or making your own speakers. It not only affects the appearance and placement of the speakers, but is also directly related to the performance of the sound quality. This article will introduce in detail the calculation method of speaker size, and provide you with a structured guide based on hot topics and hot content in the past 10 days.
1. Basic concepts of speaker size
Speaker size usually refers to the overall dimensions of the speaker, including height, width and depth. In addition, the internal volume of the speaker is also an important parameter, which directly affects the low-frequency response and sound quality.
| parameter | illustrate |
|---|---|
| high | Speaker vertical dimensions |
| width | Speaker horizontal dimensions |
| depth | Speaker front and rear dimensions |
| internal volume | The effective space inside the speaker affects the low-frequency response |
2. Calculation method of speaker size
The calculation of speaker size is mainly divided into two parts: appearance size and internal volume. The following is the specific calculation method:
1. Calculation of overall dimensions
The calculation of overall dimensions is relatively simple and usually only needs to be determined based on design requirements. For example, if you want the height of the speaker to be 50 cm, the width to be 30 cm, and the depth to be 25 cm, then the overall dimensions would be 50 x 30 x 25 cm.
2. Calculation of internal volume
The calculation of the internal volume is more complicated and requires consideration of the parameters of the speaker and the design goals of the speaker box. Here are the steps for calculating internal volume:
| step | illustrate |
|---|---|
| 1. Determine the Vas parameters of the speaker | Vas is the equivalent volume of the speaker, usually provided by the manufacturer |
| 2. Calculate the Qtc value of the speaker | Qtc is the total Q value of the speaker system, usually between 0.7-1.1 |
| 3. Calculate internal volume | Use the formula: Vb = Vas / ( (Qtc / Qts)^2 - 1 ) |
3. The relationship between hot topics in the past 10 days and speaker size
In the past 10 days, smart home and sound quality optimization have become hot topics. Many users are concerned about how to place speakers in a small space while ensuring sound quality. Here are some hot topics:
1. Tips for placing speakers in small spaces
In small spaces, the size and placement of speakers are particularly important. It is recommended to choose smaller bookshelf speakers and place them at a certain distance from the wall to reduce low-frequency reflections.
2. Size trends of smart speakers
With the popularity of smart homes, smart speakers are becoming smaller and smaller. For example, the latest Amazon Echo Dot and Google Nest Mini both feature compact designs that are suitable for use in small spaces.
3. DIY speaker craze
Recently, DIY speakers have become a hot topic. Many users try to make their own speakers, and size calculation becomes a critical step. By accurately calculating the internal volume, sound quality can be significantly improved.
4. Things to note when calculating speaker size
When calculating speaker size, you need to pay attention to the following points:
| Things to note | illustrate |
|---|---|
| 1. Speaker parameters | Make sure the speaker parameters used are accurate to avoid calculation errors |
| 2. Material thickness | When calculating the internal volume, subtract the thickness of the speaker material |
| 3. Practical testing | After the calculation is completed, it is recommended to adjust the size through actual testing |
5. Summary
The calculation of speaker size is an important part of speaker design and purchase. By accurately calculating the external dimensions and internal volume, the sound quality and applicability of the speaker can be significantly improved. The hot topics in the past 10 days also show that users have a growing demand for small space speakers and smart speakers. Hope this article can provide you with valuable reference.
