I pierced a hole in a cone shaped cardboard's tip and attached it to my phone speaker. Surprisingly the sound produced when attached is three times louder than the sound when it is removed. I do know that it is something relevant to trumpet loud speaker.What makes it to produce louder sounds?

What you did actually is the so-called horn loudspeaker. And what horns do is to narrow the propagation of sound produced by the loudspeaker. Conventional loudspeaker propagates a lot of sound up, down, left, right, etc. in relation to the axis of the cone. Horns concentrate the sound along the axis, which is therefore louder for the listener (if not located extremely to the side). That's why the police or other people who want to communicate in open space use such devices.

More technically (physically) speaking, given the displacement of the driver in your speaker (which does not change as you put the horn to it) the small cross-sectional area of the horn restricts the passage of air, which means increased air pressure in the direction of the listener as compared to your loudspeaker without the added horn, and increased pressure means increased sound volume.

As Carl Witthoft below suggested (thank you) another contributor to the higher efficiency of horn loudspeakers is the fact that they are better matching acoustical impedances of the source of the sound and the so-called load (air). The higher pressure increases the external impedance - which is naturally low due to low air density - to (better) match the impedance of the source. In (conventional) direct radiating loudspeakers this mismatch leads to a lot of energy being converted to heat within the driver instead of into the sound wave.

This has also some positive "side-effects". If designed and manufactured properly, i.e. when you are concerned mostly with the sound quality and not just with the loudness produced (which is not always the case, as you might have noticed with the police devices), horns contribute to better efficiency of the loudspeaker and lower distortion of sound. The loudspeaker's cone simply does not need to be displaced so much from rest position to produce the same volume as conventional speaker. Less displacement means less distortion of sound (and lower requirements concerning the amplifier), which can be demonstrated by the fact that good horns can produce total harmonic distortion 10 times lower than their conventional peers also considered good quality.

For quite some time horn loudspeakers were in retreat - they are big after all (especially if you want them to produce the whole spectrum of sound, including the bass, this way, as longer wave requires larger horn), which means their so-called WAF* (Wife Acceptance Factor) is rather low. Recently, however, they are coming back and are highly valued by many audiofiles, as the limitations of the smaller conventional loudspeakers became obvious. Also, more and more people are beginning to realize that the main culprit of poor sound quality is not the CD (turntable) or amplifier, but the loudspeakers.

*However, WAF can always be worked on, as can be seen - arguably - below. The real challenge is to match great sound with great visual design.

Without the cardboard, the sound waves emitted through the speakers would propagate in all directions. With the cardboard however, the sound waves emitted would be forced to propagate only from outwards the coned surface, beginning from the small opening. Since their is a smaller area for the sound waves to propagate, the sound waves interfere with each other, causing an increase in amplitude. This increase in amplitude is what causes the increased loudness.

the sound waves interfere with each other - hmmm, I can't see that this is a fair description of the physics. The sound is louder simply because the energy per unit area is higher. There is no interference involved.

One effect is, as others have already pointed out, that the cone concentrates the sound power in a narrow direction, thereby making it louder in that direction.

However, that's only part of the answer. Another important part is impedance matching. Whatever little thingy that is vibrating in the phone to make sound is much more dense than the air immediately around it. Most of the power in driving it goes into moving the thing itself. Very little of that power gets transferred to the air. Or put another way, the air getting pushed is hardly loading the speaker. It would take about the same amount of driving power to run the speaker in a vacuum.

A horn presents more load onto the driving element at the narrow end, by causing more air to get moved at the wide end. The ideal shape for such a horn is exponential, but a simple cone still works much better than nothing, as you have seen. The horn is a impedance matcher that converts the high impedance at the wide end to a low impedance at the narrow end. This low impedance can pick up more power from the low impedance motion of the small speaker in the phone.

This effect is exactly why most wind intruments are horn shaped. Think of a tuba, trumbone, or even a clarinet to some extent. Your vibrating lips (tuba, trumbone) or vibrating reed (clarinet) produce sound at a low impedance, which the horn shape helps couple to the air better.

In summary, the sound is getting concentrated in a more narrow beam, AND there is more sound power extracted from the same speaker.
