Description

Bass Boosted Speakers

technical field

The utility model relates to a sound box, in particular to a bass enhanced sound box.

Background technique

With the popularization of consumer electronic products such as notebook computers, mobile phones, and Walkmans and the continuous advancement of technology, today's consumer electronic products are paying more and more attention to their audio-visual functions, especially the application of music playback. Therefore, how to make the original sound Reproducibility has become a big topic.

The sound quality of the sound played by electronic products is not only related to the speaker itself, but also very related to the speaker covered outside the speaker. According to the internal structure of the speaker, it can be divided into closed type, phase-inverted type, transmission line type, etc., especially The closed speaker is one of the most used speakers at present. The so-called closed speaker is to install the speaker in a completely closed box, and use the box to separate the sound radiation from the front and back of the speaker to prevent acoustic short circuit. Since the air in the closed speaker has a certain damping effect on the vibration of the speaker, it has a certain impact on the resonance frequency and quality factors of the speaker, and the increase in the volume of the speaker can reduce the above effects.

However, due to people's aesthetic needs and the limitation of external space, the speakers are often required to be as small as possible. When the current speakers are small, the pronunciation effect is bound to be greatly reduced, especially the effect of the bass part is even worse, and it may even make the playback The music has no bass effect, so that the listener cannot feel the dynamics of the music, resulting in distortion. Therefore, it is very important to improve the design of the speaker.

Utility model content

The purpose of the utility model is to provide a bass-enhanced speaker with smaller volume and better low-frequency performance in view of the defects and deficiencies of the above-mentioned prior art.

In order to achieve the above object, the bass enhanced sound box provided by the utility model includes a sound box body and a loudspeaker, the sound box body includes a front side box wall and a rear side box body, the loudspeaker is fixed on the front side box wall, and the front side box The walls have a certain rigidity, and the rear box includes a first box made of elastic material.

According to the principle that the larger the vibration area and the lower the regeneration frequency described in physics and acoustics, the utility model uses the resonance energy of the back wave of the speaker to make the first box of the rear box made of elastic material Resonance makes the first box become the sounding surface of the speaker, thereby increasing the vibration area of the speaker, pushing more air, and generating more low frequency, so that a smaller volume speaker can achieve better low frequency performance.

Description of drawings

Fig. 1 is a perspective view of a sound box body of an embodiment of the bass enhanced sound box of the present invention.

The reference signs of each component in the figure are explained as follows:

Speaker body 1 Front side wall 2

Rear cabinet 3 First cabinet 31

Second box 32

Detailed ways

In order to describe the technical content, structural features, achieved goals and effects of the present utility model in detail, the following will be described in detail in conjunction with the embodiments and accompanying drawings.

Please refer to Fig. 1, the bass enhanced sound box of the present utility model comprises a sound box body 1 and loudspeaker (not shown in the figure), and this sound box body 1 comprises a front side box wall 2 and a rear side box body 3, and the loudspeaker is fixed on the front side on the box wall.

The front side box wall 2 is made of a material with a certain rigidity, and the specific material is not limited, so that the front side box wall 2 has a certain rigidity.

The rear box 3 includes a second box 32 with a certain rigidity and a first box 31 placed inside the second box 32 . The second box body 32 of the rear side box body 3 is integrally formed with the first box body 31 , or the first box body 31 is glued to the inner side of the second box body 32 . The second box body 32 of the rear side box body 3 is made of a material with a certain rigidity, not limited to a specific material, and the first box body 31 of the rear side box body 3 is made of an elastic material, not limited to a specific material. In addition, the sound box body 1 can be a circular body, a triangular body, a polygonal body and other box structures with certain shapes.

When the utility model bass-enhanced sound box is used, according to the principle that the larger the vibration area described in physics and acoustics, the lower the regeneration frequency, the resonance energy of the back wave of the speaker is used to make the rear box 3 made of elastic material The first cabinet 31 resonates so that the first cabinet 31 becomes the sounding surface of the speaker, thereby increasing the vibration area of the speaker, pushing more air, and generating more low frequencies.

To sum up, the first box body 31 made of elastic material for the bass-enhanced speaker of the present invention can increase the vibration area of the speaker, so that a smaller volume of the speaker can achieve better low-frequency performance.
