Voice optimization loudspeaker

Abstract

The invention relates to a voice optimize loudspeaker used in portable device, which is a hollow box. Wherein, the surface of box is arranged with a mounting base for the player, a loudspeaker voice inlet and at least one outlet; said inlet is arranged opposite to the loudspeaker of player; the voice of internal loudspeaker of portable device, via the reflection inside the box and initializing the box to resonate, is played from the outlet, with amplified volume and beautiful tone, without any addition expanding circuit and loudspeaker, with low cost and small volume.

Description

technical field [0001] The invention relates to a sound-optimized loudspeaker device. In particular, a passive sound-optimized amplification device. Background technique [0002] With the development of electronic technology, various portable devices such as walkmans and handheld computers are increasingly widely used. Due to the need for portability, these devices mostly use earphones or built-in small speakers to play the sound. The earphones can only meet personal appreciation, and long-term use will cause ear hearing damage, while the output power of the built-in small speakers is small, and the sound quality is poor. Difficult to meet the needs of music playback. In view of the above problems, the prior art uses an external speaker device to solve it, which can be divided into two types: passive and active. Among them, the passive speaker device is realized by installing a speaker with a smaller driving power in the box. However, due to the The sound output power of ...

Problems solved by technology

Due to the need for portability, these devices mostly use earphones or built-in small speakers to play the sound. The earphones can only meet personal appreciation, and long-term use will cause ear hearing damage, while the output power of the built-in small speakers is small, and the sound quality is poor. Difficult to meet the needs of music playback

In view of the above problems, the prior art uses an external speaker device to solve it, which can be divided into two types: passive and active. Among them, the passive speaker device is realized by installing a speaker with a smaller driving power in the box. However, due to the The sound output power of itself is limited, and the volume of passive speaker devices is still low. At the same time, the power consumption of portable devices is increased and the use time is shortened; while active speaker devices need to add additional amplification circuits and speakers, which can solve the problem. The volume and sound quality are problematic, but its disadvantage is that it needs power supply and is large in size. Even if dry batteries are used as the power supply, its use time is still limited, and it is difficult to meet the needs of portability.
