The size of the speaker is determined according to the characteristics of the speaker, including the equivalent volume of the speaker, Q value, vibration quality, and effective radius. The size of speakers of different manufacturers and models is not fixed. We can customize speakers of any size according to customer requirements.
Speaker size introduction:
The size of an speaker can be calculated in inches by measuring the outer diameter of the speaker, 1 inch = 2.54 cm. For example, a 4-inch speaker has a diameter of 2.54*4=10.16 cm.
Almost all speakers on the market are calculated by size and actual mm. The inch in the speaker is inches (in), 1 inch = 63.5px = 25.4mm. A standard 2-inch speaker has a diameter of 50.8mm. Among them, the diameter of the horn refers to the caliber of the horn. For example, a speaker with a diameter of 100mm is required. The conventional recommendation is a speaker with a diameter of 100/25.4≈4 inches.
Under normal circumstances, a two-way speaker with a 6.5-inch bass speaker has a net volume of about 14 liters, an 8-inch speaker 36 liters, and a 10-inch speaker 44 liters.
The volume calculation method of the speaker is quite complicated, and it is related to the following factors:
1. Horn parameters: including the equivalent area of the diaphragm, resonant frequency, and Q value.
2. Speaker type: the so-called non-punched box is called a closed box or closed box; the so-called punched box is called an inverted box; there are other structural forms.
3. Leakage of the speaker itself: Except for the necessary openings, whether there is any leakage and how much leakage is.
4. The target parameters of the speaker to be designed (these parameters are also subject to items 1 and 2 at the same time): low-frequency cut-off frequency, flatness, etc.
As a professional bluetooth speaker manufacturer, we can customize and design any size speaker according to customer needs. Please kindly send us an inquiry for further customized information.
