TECHNICAL FIELD

The present disclosure relates to the technology field of speakers, and in particular to a speaker box structure and an electronic device.

TECHNICAL BACKGROUND

Some electronic devices on the market today are made very thin in order to have a good-looking appearance. Correspondingly, ultra-thin speaker box structures are also required. Currently, in order to match the overall appearance, this type of speaker box structure is equipped with a single or two full-range speakers of the same specifications inside the speaker, and then a sound guiding structure or horn is added in front of the speaker to guide the sound out. However, after the full-range speaker is reflected by the sound guiding structure or horn, the high frequency will have large losses, which will lead to poor overall sound effects. In order to have better high-frequency sound effects, the vibration quality of the speakers can only be made lighter, but this will also cause a certain loss in the low frequencies. In order to improve the low-frequency sound quality, currently it only can be improved by adjusting and increasing DSP, but when the DSP is adjusted too high, excessive distortion will be caused.

Therefore, it is necessary to design a speaker box structure with better high-pitched and bass effects.

Referring toFIGS.1to4, an embodiment of the present disclosure provides a speaker box structure, which may be applied to a variety of electronic devices, such as interactive display screens. According to this embodiment, the speaker box structure includes: a speaker box housing1, a sound guiding member2, a high-pitched speaker3, and a mid-bass speaker4.

The sound guiding member2is installed on the speaker box housing1. The sound guiding member2forms a high-pitched sound guiding channel201and a mid-bass sound guiding channel202at intervals. The high-pitched sound guiding channel201has a sound inlet facing the speaker box housing1and a sound outlet2012facing away from the speaker box housing1. Similarly, the mid-bass sound guiding channel202has a sound inlet2021facing the speaker box housing1and a sound outlet2021facing away from the speaker box housing1. The sound inlet2011of the high-pitched sound guiding channel201and the sound inlet2021of the mid-bass sound guiding channel202are located at the same end of the sound guiding member2. The sound outlet2012of the high-pitched sound guiding channel201and the sound outlet2022of the mid-bass sound guiding channel202are also located at the same end of the sound guiding member2.

The high-pitched speaker3is disposed on the speaker box housing1and is opposite to the sound inlet2011of the high-pitched sound guiding channel201. The high-frequency sound emitted by the high-pitched speaker3may pass through the sound inlet2011of the high-pitched sound guiding channel201and emits from its sound outlet2012after being guided through the high-pitched sound guiding channel201.

The mid-bass speaker4is disposed on the speaker box housing1and is opposite to the sound inlet2021of the mid-bass sound guiding channel202. The mid-low frequency sound emitted by the mid-bass speaker4may pass through the sound inlet2021of the mid-bass sound guiding channel202, and emits from its sound outlet2022after being guided through the mid-bass sound guiding channel2022.

It can be seen from the above technical solution that, according to the embodiment of the present disclosure, the speaker box structure respectively emits sounds of different frequencies by arranging the high-pitched speaker3and the mid-bass speaker4, and guides and transmits separately the high-frequency and mid-low frequency sounds by arranging the high-pitched sound guiding channel201and the mid-bass sound guiding channel202in the sound guiding member2. The two sounds are constrained by their different sound guiding channels, which can better guide and transmit the sounds. It not only effectively improves the sound effect, but also achieves the emission of full-range sounds. According to the embodiment of the present disclosure, the speaker box structure has better high-pitched and bass effects without additional adjustments, and has a simple overall structure. The guide and transmission of sounds is concentrated on a sound guiding member2, which makes installation and use more convenient.

It should be noted that there are two wiring and sound separation methods for the high-pitched speaker3and the mid-bass speaker4.

A first type, the high-pitched speaker3and the mid-bass speaker4may be connected to the wire7separately. The wire7is led out and connected to an external electronic crossover. The external electronic crossover transmits signals of different frequencies to the high-pitched speaker3and the mid-bass speaker4respectively, thereby realizing the emission of sounds. A second type, by installing an audio crossover inside the speaker box housing1, the high-pitched speaker3and the mid-bass speaker4are connected to the audio crossover, thereby realizing the emission of sounds of different frequencies.

It should be noted that the number of high-pitched sound guiding channels201and mid-bass sound guiding channels202may be adjusted according to actual needs, as long as the number of high-pitched speaker3and high-pitched sound guiding channels201is in one-to-one correspondence, and the number of mid-bass speakers4and mid-bass guiding channels202is in one-to-one correspondence.

In order to achieve a better bass effect, preferably, in this embodiment, two mid-bass sound guiding channels202are provided, and the two mid-bass sound guiding channels202are symmetrically arranged on both sides of the high-pitched sound guiding channel201, thereby obtaining better bass sound quality. Definitely, in order to make the high-pitched effect better, in some other embodiments, there are two high-pitched sound guiding channels201, and the two high-pitched sound guiding channels201are symmetrically arranged on both sides of the mid-bass sound guiding channel202(not shown in the figures), thereby obtaining better high-pitched sound effect.

As shown inFIGS.1,3, and4, in this embodiment, a plurality of shunt partition bars23are provided in the mid-bass sound guiding channel202, and the plurality of shunt partition bars23are arranged at intervals in sequence to separate the mid-bass sound guiding channel202to multiple branch channels2023. The mid-bass-frequency and low-frequency sounds are output to the sound outlet2022through multiple branch channels2023. The sounds are isolated from each other, which can effectively avoid sound interference in the horizontal and left directions, making the output bass sound better. Specifically, the shunt partition bar23extends along the direction from the sound inlet2021to the sound outlet2022of the mid-bass sound guiding channel202.

The sound guiding member2may be integrally formed, but in order to facilitate production and reduce manufacturing costs, the sound guiding member2according to this embodiment includes a first sound guiding housing21and a second sound guiding housing22that are connected to each other. The first sound guiding housing21and the second sound guiding housing22collectively surround and form a high-pitched sound guiding channel201and a mid-bass sound guiding channel202.

In order to facilitate the assembly of the overall speaker box structure, the sound guiding member2according to this embodiment includes a clamping groove24at the sound inlet2011of the high-pitched sound guiding channel201. The high-pitched speaker3is clamped and fixed in the clamping groove24, and the high-pitched speaker3is disposed on the speaker box housing1at intervals, that is, there is a certain gap between the high-pitched speaker3and the speaker box housing1, so that the heat dissipation effect of the high-pitched speaker3can be improved.

In one embodiment, the speaker box housing1of this embodiment includes an installation groove111, and the mid-bass speaker4is embedded in the installation groove111, which can effectively improve the air tightness of the mid-bass speaker4and facilitate the installation of the mid-bass speaker4.
