FIG. 1 is a perspective view of a rear housing in a preferred embodiment of the present invention;
FIG. 2 is another perspective view of the rear housing in the preferred embodiment of the present invention;
fig. 3 is a sectional view of a rear case according to a preferred embodiment of the present invention.
Detailed Description
The technical solution of the present invention will be further explained with reference to the accompanying drawings and the detailed description.
Referring to fig. 1-3, in the embodiment, taking the rear housing of the television as an example, the technical solution of the present invention can be applied to any other electronic products with a display screen, such as a mobile phone, a notebook computer, a tablet computer, and the like.
The television rear shell is divided into a first surface 1 facing the back side of the display screen and a second surface 2 far away from the back side of the display screen; an accommodating space is formed between the first surface 1 and the second surface 2, and the first surface 1 and the accommodating space fill a gap between the second surface 2 and the back of the display screen; the rear shell is also provided with a hole 4 for installing the loudspeaker unit 3, and the hole 4 is communicated with the accommodating space to reuse the rear shell as a box body of the sound box.
Thus, the space existing in the original television is utilized to be the box body of the loudspeaker unit 3, the loudspeaker unit 3 and the rear shell jointly form a sound box, and the box body of the sound box is very large, so that the tone quality of the sound box can be greatly increased.
In this embodiment, the rear case is integrally formed by blow molding. Thus, the desired shape can be blown out through the blow molding process for different models of televisions, so that the rear shell can be adapted to all televisions for use.
Because the electronic product is provided with components such as the control circuit board besides the display screen, the components need the heat dissipation air duct for heat dissipation, and if the accommodating space is filled with the heat dissipation air duct, the heat dissipation is greatly influenced. Therefore, the accommodating space avoids the heat dissipation air duct of the display screen and the control circuit board.
Meanwhile, the second surface 2 is provided with an air inlet and an air outlet corresponding to the position of the heat dissipation air duct. Therefore, outside air can enter the heat dissipation air duct through the air inlet and then be blown out from the air outlet to take away heat, and heat dissipation is achieved.
In this embodiment, the rear housing is further provided with a sound releasing structure 6 for guiding out the sound emitted by the speaker unit 3 at the hole 4; the sound releasing structure 6 includes:
a loading chamber 61, the loading chamber 61 communicating with the cone of the speaker unit 3;
at least one flat horn 62 connected transversely to the loading chamber 61; and a sound releasing port 63 at the end of each of the flat horns 62; wherein the cone is communicated with the free space through a complete airflow passage formed by the loading cavity 61, the flat horn 62 and the sound releasing port 63 in sequence.
The loading chamber 61 may have a cross-section that completely accommodates the cone; the flat horn 62 gradually expands on a vertical plane of the cone central axis from the loading chamber 61 to the release port 63.
In this embodiment, the opening direction of the sound releasing port 63 is perpendicular to the central axis of the cone.
Because the loading cavity 61 is transversely connected with the flat horn 62, the scheme of a loudspeaker system can be completed in a very limited thickness space, the loudspeaker is hidden, and the frequency response effect of the loudspeaker can be processed in a targeted manner, so that the aim of optimizing the effect of the loudspeaker is fulfilled.
The loudspeaker unit 3 is arranged in the loading cavity 61, and the axial reserved space at the back part of the loudspeaker unit is small; the traditional thinking can think that the axial sound reflection in the reserved space can generate reflection standing waves, so that the loading cavity can not be designed in a flat mode, and a deep loading cavity is needed; in fact, the frequency of the standing wave can be accurately controlled according to the thickness of the reserved space, so that the frequency of the standing wave is limited to be out of an effective output frequency band, the auditory effect is not affected despite the standing wave, and the technical bias is overcome.
The loading cavity 61 is transversely connected with the flat horn 62, so that symmetrical horn input ports in the same plane can be distributed, a composite design of multiple horns is formed, and the sound effect can be processed and improved in multiple bands.
The loading cavity 61 is transversely connected with the flat horn 62, so that the sound cone with various shapes can be adapted, and the system has strong compatibility.
The loading chamber 61 is designed to face the cone shape of the speaker unit, which can form an effective load for the speaker and ensure output efficiency.
The sound release port 63 of the flat horn 62 can output sound volume under a very limited frame width, further improving the effect of hiding the speaker.
In this embodiment, flat horn 62 is circular-arc for release mouth 63 is just to the user, can increase very little size just so at the display screen bottom and can lead to spectator with the sound of loudspeaker, avoids loudspeaker to produce different reflection downwards, leads to sound to transmit spectator to have more uncontrollable factor occasionally.
The above description is only an exemplary embodiment of the present invention, and the scope of the present invention should not be limited accordingly. The equivalent changes and modifications made according to the patent scope and the content of the specification of the present invention should still fall within the scope covered by the present invention.
