Description

a loudspeaker device

technical field

The utility model relates to a loudspeaker device, in particular to a loudspeaker device that can rotate in a horizontal plane.

Background technique

In the prior art, the speakers of the TV are mostly fixed on both sides of the TV and cannot be rotated. Although there are some public information showing that the speakers of a small number of TVs can be rotated, the positive direction of the speaker can be directed towards the Audience, to achieve a more ideal reception, but there are still some defects.

For example, Chinese patent 200520034698.5, which was authorized and announced on November 29, 2006, shows a speaker device that can rotate in the horizontal plane. The device is turned slightly inward, so that the audience can receive the highest and clearest sound, but it does not consider the situation of a large number of people, that is, when there are many audiences, not all of them must be located directly in front, especially the tweeter unit has an impact on the sound field. Strong directivity is required so that no matter how you turn the speaker, someone will get a less-than-ideal hearing. In addition, even if a small number of people listen to it, it is impossible to obtain more reception options with different effects according to personal preferences.

Utility model content

Based on this, the technical problem to be solved by the utility model is to provide a loudspeaker device, the loudspeaker of which can be rotated within a certain range, can meet the audio-visual needs of multiple people, and can form different auditory experiences.

In order to solve the above problems, the speaker device of the present invention includes a rotatable left channel speaker, a right channel speaker and a support, and is characterized in that there are at least two left and right channel speakers respectively, which are respectively connected to the same Left and right sound output sources, and at least one speaker on each side can be rotated horizontally.

A rotating device matched with the rotatable loudspeaker is arranged on the support.

The bracket can be an independent support body with a base, or a multi-component combination that needs to be fixed on the walls of other objects.

Since the utility model adopts a plurality of independent speakers, and at least one of the left and right speakers can be rotated horizontally, various sound effect combinations can be formed, and when there are many people, the listeners who are not directly in front of the speakers can also feel The strong sound effect can achieve the auditory effect as if you are in the front. In addition, by turning the pronunciation direction of each speaker, it is possible to form a free combination of different styles according to the preference of a single listener.

Detailed ways

Now in conjunction with accompanying drawing, the utility model is described in further detail.

As shown in Fig. 1, 2, 3, what show is that each channel of the utility model has two rotatable loudspeakers when a kind of connection structure that combines with common TV, the left upper loudspeaker 21 and left lower loudspeaker 21 are equipped with on the left side of TV casing 1. Loudspeakers 22 are fixed on the left side of the TV through combined brackets 23, 24, 25, wherein the right side of the bracket is externally connected to the left side of the TV casing 1, and there are many specific ways, as an example, If the bracket 23 has a bent inverted F shape, a screw through hole 231 is punched in the plane part on the right side, the through holes are at least two and equal in height, and the screw holes corresponding to it are punched on the TV casing 1, then the screw can be used. Fix the bracket 23 on the side of the casing 1 . The fixing method of the brackets 24 and 25 can be similar to that of the bracket 23 . In this way, the upper left speaker 21 can be placed between the brackets 23 and 24 , and the lower left speaker 22 can be placed between the brackets 24 and 25 .

In order to allow the loudspeaker 21 to have better positioning and rotatable flexibility after being put in, various methods can also be adopted. To give an example here, for example, a cylindrical protruding portion 232 can be made in the center of the lower side of the bracket 23, and a groove 211 can be made in the corresponding part of the top center of the upper left speaker 21. The speaker 21 rotates around the cylindrical protrusion 232 as an axis. If the lower left loudspeaker 22 is to be fixed, it can be the same with this principle, the screw through holes 241,251 of the supports 24,25 and the cylindrical protrusion 242 of the support 24 are the same as the support 23.

The fixing and connection methods of the upper right speaker 31 and the lower right speaker 32 can be the same as that of the left side.

The rotatable speaker device described in the utility model does not have to be hung on the left and right sides of the TV, because a large number of independent speaker devices have emerged at present. This independent speaker can be erected on both sides of the TV, but not It is tightly hung on the left and right sides of the TV, and it is not integrated with the TV. As shown in FIG. 4 , a rotatable independent speaker device is shown. The left speaker has an upper left speaker 21 and a lower left speaker 22 , and the right speaker has an upper right speaker 31 and a lower right speaker 32 . The sound signal output source on the left side of the TV can be divided into two signal lines and connected to the upper left and lower left speakers, and the sound signal output source on the right side of the TV can also be divided into two signal lines to be connected to the upper right and lower right speakers. The left and right brackets respectively have a supporting part and a spatial position for accommodating a single loudspeaker. Here, a rotating shaft similar to that shown in FIG. 2 and FIG. 3 can also be used to make the single speaker easier to rotate.

As shown in FIG. 5 , the sound receiving effect principle of the rotatable speaker device will be further described in detail. As shown in the figure, point O is the center point of the TV screen, and its left side is the upper left speaker 21 and the lower left speaker 22. Generally, when all the speakers are facing the front, the listeners in points C to D can obtain better sound effects. Since the sound must have a higher intensity in the direction of forward propagation, take the sound in the N direction in the figure as an example, it must have better intensity when it reaches point C, and it will sound attenuated at point E. At the same time, the listener at point E hears the sound at point D on the other right side is weaker, and considering the factors after it is mixed with the sound on the right side, the sound effect is bound to be not very good. In particular, the tweeter unit has a strong directional requirement for the sound field, which is even more prominent.

In the published Chinese patent 200520034698.5, it is mentioned that the left and right sides should be rotated inwards to align with the audience A directly in front. At this time, although the intensity of point A is the highest and the effect is good, the audiences of points B and E are not satisfied. need. And the utility model has solved the problem of taking care of one thing and losing another well, that is, the left and right loudspeakers are respectively made into two, and can rotate in the horizontal plane. When there are listeners at points A, B, and E, you can adjust the upper left or lower left speaker so that one is facing straight ahead and the other is turned slightly to the outside. In this way, since the M sound wave is sent to point E, the listeners at points E and B can also Satisfy the demand, so as to achieve a balance, that is, whether the listener is directly facing the TV or slightly facing the audience, the sound intensity and sound effect felt by them are similar, and there will be no obvious difference in strength or weakness.

In addition, when only the listener is at point A, due to different personal preferences, he does not necessarily like the left and right speakers to turn inwards to point A. At this time, due to the rotatability of the four individual speakers, it is determined that multiple Different sound effect styles, for example, the upper left speaker 21 and the upper right speaker 31 are directly facing the front, and the lower left speaker 22 and the lower right speaker 32 are turned outward to aim at the indoor wall, relying on the reflected sound of the wall and the forward direction (as shown in the figure 5 in N direction) sound mixed to form different effects.

The independent loudspeaker in Figure 4 has an effect principle similar to that described above.

Based on the above principles, according to the utility model, at least one left speaker can rotate in the horizontal direction, and at least one right speaker can rotate in the horizontal direction, that is to say, the four speakers can all rotate horizontally, and It can be that the upper left speaker 21 and the upper right speaker 31 are fixed as conventional speakers, and only the lower left speaker 22 and the lower right speaker 32 can be rotated horizontally, or an approximate combination. These changes can be determined according to product requirements.

The above is only a preferred implementation example of the present utility model, and cannot limit the protection scope of the present utility model with this. Various changes and modifications made by those skilled in the art without departing from the spirit and scope of the present utility model are included in the utility model. within the coverage.
