You can't use high-power stage speakers at home, because the speakers are powerful and need power amplifiers. If the power amplifier is too low, the sound of the speaker will be interrupted. (If the power amplifier exceeds 2/3 of the output power, it will be seriously distorted. )
The rated power of 60- 100W is enough for home use, and the speaker of 60W needs the power amplifier of 120W to push it, so the sound quality is very good. Because 120W is only turned on below 60W, there is no distortion. (60W*2 sound effect, a room within 40 square meters is enough)
The cost of the speaker is very simple, that is, speaker+divider+box.
Now there are many fake speakers, fake speakers. The speakers of these speakers are cheap and inferior speakers with low cost and poor bass.
A big horn is a big magnet. The installation of large magnetic steel is very simple, without technical content, and ordinary magnetic steel is worthless; However, the bass frequency technology of the horn is relatively high. Generally, small factories do not have this technology, but the appearance does not mean that the bass is not good.
Brand-name 15 inch speakers are more expensive, with good bass, but very powerful, which is not suitable for home use.
A famous brand speaker 15 inch 1000 yuan, a cottage speaker 15 inch 100 yuan, but not a professional, there is no way to tell.
Therefore, home speakers cannot choose high-power stage speakers.
How much does it cost to buy a speaker? What do you think of the sound quality?
When configuring audio, the following requirements should be considered when purchasing speakers:
1. For general enjoyment, using a computer or handheld digital device as the sound source (software decoding), it is recommended to choose an active speaker within 2000 yuan.
2. If the pursuit of perfection (voice fever), the use of specialized playback equipment (CD, DVD, Blu-ray player, decoder) as the sound source (hard decoding), the price of the whole set of equipment should be more than 3,000 yuan. At this time, the speaker accounts for 1/3 ~ 1/2 of the whole equipment price (mainly considering whether the speaker is in place at one time) (1) If the speaker configuration is in place at one time, the speaker accounts for 1/2 of the whole equipment quotation. (2) If the loudspeaker upgrade is considered in the future, it is suggested that the loudspeaker account for 1/3 of the quotation of the whole set of equipment.
How to calculate the cost price?
Cost price calculation method:
1, production cost = direct materials+direct wages+direct expenses.
2. Sales cost = production cost+sales expenses, including advertising fees, freight, taxes, etc.
3. Ending cost = opening balance+current period increase-current period decrease.
4. Total product cost = total fixed cost+total variable cost = total fixed cost+variable cost per unit product × total product.
5. Target cost per unit product = predicted ex-factory price ×( 1- tax rate)-profit target/predicted output.
6. Product unit cost = (total fixed cost ÷ total product)+unit variable cost = total product cost ÷ product output.
7. Cost of finished products = output of finished products × distribution rate.
8. Stock cost = the price of stock purchase+brokerage fee+stamp duty+transfer fees.
1, cost price originally refers to the price of goods purchased by merchants. Cost price is not ex-factory price. The cost price includes certain formalities fees, and sometimes other fees are added. If it is a self-produced commodity, its cost price includes raw materials, workers' wages, depreciation expenses to be shared, production management personnel's wages, utilities, maintenance fees, etc. ; If the goods are purchased, the cost price is the purchase value of the goods. If there is freight, the freight will be added, sometimes called ex-factory price.
2. But in the stock market, the cost price refers to the actual price of the stock, and the cost price of the stock is the collection of stock price, brokerage fee, stamp duty and transfer fees. The cost price in a stock refers to a part of what users spend when buying a stock. The mainland stock market stipulates that users do not need to collect stamp duty when purchasing, but only charge a handling fee. No matter how much investors invest, as long as there is a transaction, there is a cost. Buying stocks is different from buying goods by merchants. Commodity prices will not change rapidly, but stock prices will fluctuate in a short time.
Principles to be followed in calculating cost:
1, the principle of legality;
2. The principle of reliability, including authenticity and verifiability;
3. The principle of relevance;
4. The principle of accounting by stages;
5. The principle of accrual basis;
6, the actual cost pricing principle;
7. The principle of consistency;
8, the principle of importance.
