Description

Sound box convenient for bidirectional voice communication

Technical Field

The utility model relates to a sound box technical field, in particular to audio amplifier convenient to two-way pronunciation are communicated.

Background

In the existing microphone and sound box all-in-one machine, when the function of playing sound by the sound box is realized, the sound directly coming from a loudspeaker is output, and the microphone and the sound box share a sound cavity, so that the sound head of the microphone is easy to pick up the sound emitted by the sound box, the howling problem is generated, and the problem is usually solved by reducing the gain in order to relieve the howling problem. However, the reduction of the gain can weaken the sound effect integrally, so that the voice is clumsy, the use experience of the user is reduced, and the good feeling of the user is weakened.

An aspect of the utility model discloses an audio amplifier convenient to two-way voice communication, the inside of box is hollow cavity, be equipped with loudspeaker on the at least panel of box, the box is not equipped with be equipped with the receiving phone window on other arbitrary panels of loudspeaker, be equipped with on the box with the holding chamber that the receiving phone window link up, be equipped with the microphone in the holding chamber, the pickup portion of microphone is aimed at the receiving phone window, the holding chamber with the cavity space is isolated, the bore of receiving phone window is 0.5mm to 1.5mm, the bore depth of receiving phone window is not more than 1.5mm.

Furthermore, a bearing plate is arranged on one side, close to the telephone receiving window, in the cavity, and the accommodating cavity is arranged between the end face of the bearing plate and the inner wall of the box body.

Furthermore, a loudspeaker is embedded in the front panel of the box body, the telephone receiving window is arranged on the top panel of the box body, and the bearing plate is arranged below the top panel of the box body at the top of the cavity.

Furthermore, one side of the accommodating cavity is provided with a wire groove communicated with the cavity, and a connecting wire is arranged in the wire groove and sealed by filler.

Furthermore, a rubber pad is arranged between the outer wall of the microphone and the inner wall of the accommodating cavity.

Preferably, the aperture of the receiving window is 1mm.

Preferably, the hole depth of the telephone receiving window is not more than 1mm.

The beneficial effects of the utility model are that:

1. the telephone receiving window and the loudspeaker are arranged on different panels of the box body, so that the interference of the sound production of the loudspeaker and the sound pickup of the microphone is prevented, the howling problem is relieved, and the two-way high-quality voice communication is realized;

2. the holding cavity is isolated from the cavity space to achieve the effect of sound insulation and ensure the high-quality sound pickup of the microphone.

Detailed Description

The invention will be further explained with reference to the drawings and examples.

The embodiment is as follows: as shown in fig. 1 to 4, a sound box facilitating two-way voice communication includes a box body, the inside of the box body is a hollow cavity, a speaker 1 is embedded on a front panel of the box body, a mesh enclosure 2 is covered on the speaker 1, a receiving window 3 is arranged on a top panel of the box body, a bearing plate 4 is arranged on one side of the cavity close to the receiving window 3, an accommodating cavity 41 communicated with the receiving window 3 is arranged on an end surface of the bearing plate 4, a microphone 5 is arranged in the accommodating cavity 41, a sound pickup portion of the microphone 5 is aligned to the receiving window 3, a sound pickup direction of the microphone 5 is perpendicular to a sound production direction of the speaker 1, the accommodating cavity 41 is isolated from the cavity space, an aperture of the receiving window 3 is 0.5mm to 1.5mm (preferably 1mm in this embodiment), and a hole depth of the receiving window 3 is not greater than 1.5mm (preferably 1mm in this embodiment). One side of the accommodating cavity 41 is provided with a wire slot 42 communicated with the cavity, a connecting wire is arranged in the wire slot 42 and sealed by filler, and the accommodating cavity 41 is ensured to be isolated from the cavity space. A rubber pad 43 is arranged between the outer wall of the microphone 5 and the inner wall of the accommodating cavity 41, so that the effects of vibration prevention and sound insulation are achieved, and high-quality sound pickup of the microphone 5 is guaranteed.

The working principle of the embodiment is as follows: during use, when the loudspeaker box receives a voice signal transmitted by a network, the voice signal is played through the loudspeaker 1, meanwhile, a receiver as information can also send out voice, the voice is transmitted to the microphone 5 in the accommodating cavity 41 through the receiving window 3, the microphone 5 transmits the picked voice signal to the loudspeaker box, the voice signal is transmitted to the other side through the network, and the function of bidirectional voice communication can be realized through a single loudspeaker box. Meanwhile, the loudspeaker box also has the functions of playing music and the like, and because the opening direction of the receiving window 3 is perpendicular to the audio broadcasting direction of the loudspeaker 1, audio playing and voice pickup can be carried out simultaneously without mutual interference, howling is avoided, and good voice communication experience is achieved.

The above is only the preferred embodiment of the present invention, the present invention is not limited to the above embodiment, there may be local minor structural modification in the implementation process, if it is right that various modifications or variations of the present invention do not depart from the basic principle and scope of the present invention, and belong to the claims and the equivalent technical scope of the present invention, then the present invention is also intended to include these modifications and variations.
