Description

Bluetooth sound box

Technical Field

The invention relates to the field of sound boxes, in particular to a Bluetooth sound box.

Background

The bluetooth speaker indicates built-in bluetooth chip to the stereo set equipment that traditional wire rod was connected is replaced in the bluetooth connection, through being connected with bluetooth playback devices such as cell-phone panel computer and notebook, reaches convenient and fast's purpose.

At present, bluetooth speaker uses portable audio amplifier as the main, and the appearance is generally comparatively small and exquisite portable, and bluetooth speaker technique also relies on its characteristics that make things convenient for the people to be valued at the consumer gradually and accept, and common bluetooth speaker on the market is mostly single sound channel audio amplifier (single speaker unit), has also emerged the multichannel audio amplifier that some tone quality are excellent simultaneously (two or more speaker unit).

The Bluetooth sound box is generally of an integrated shell structure, and the shell of the structure has poor shock resistance, so that when the whole sound box falls on the ground carelessly, internal electronic components can be damaged; moreover, because speaker and mainboard set up in a cavity, its heat can transmit each other, leads to the mainboard heat to increase, and heat dispersion worsens, and in addition, the vibrational force when the speaker broadcast can transmit the mainboard for the rear end, and consequently the vibration that lasts can lead to the long-time vibration of mainboard component and life-span to reduce. In addition, the existing Bluetooth sound box is smaller and smaller in size, and when the Bluetooth sound box is placed on a desktop, due to the fact that the Bluetooth sound box is of a round structure in many times, the Bluetooth sound box is not well placed, the desktop area is occupied, clamping can be carried out only by additional clamps, and the structure is complex.

As the preferred technical scheme, install the speaker in the first casing, install the bluetooth mainboard in the second casing, install the bluetooth chip on the bluetooth mainboard, match through bluetooth chip and cell-phone bluetooth audio frequency, be connected through the speaker connecting wire between bluetooth mainboard and the speaker, the connecting wire passes the inlet and outlet air aperture on first casing and the second casing respectively, the outside end of first casing is just facing the speaker and is provided with out the sound net.

As an optimized technical scheme, the elastic piece adopts a return spring, one end of the return spring is fixedly bonded with the end face of the first shell through glue, and the other end of the return spring is fixedly bonded with the end face of the second shell through glue.

As the preferred technical scheme, the soft layers are all elastic rubber layers with deformation recovery capacity, one sides of the elastic rubber layers, opposite to the elastic parts, are provided with more than one air suction holes, and the air suction holes are communicated with the air storage cavities in the elastic rubber layers.

As a preferable technical scheme, the anti-slip patterns are scribed on the opposite surfaces of the first soft layer and the second soft layer.

The invention has the beneficial effects that: according to the Bluetooth sound box, the loudspeaker is separated from the main board, the problem of heat transfer is solved, the vibration influence of the loudspeaker on the main board is reduced, meanwhile, the split type shell can be used for clamping and fixing at any position, the Bluetooth sound box is more convenient, and has very good heat radiation performance and anti-falling capacity.

Drawings

In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings used in the description of the embodiments or the prior art will be briefly described below, it is obvious that the drawings in the following description are only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to the drawings without creative efforts.

FIG. 1 is a schematic view of the present invention in its non-use configuration;

fig. 2 is a schematic structural diagram of the invention during clamping.

Detailed Description

As shown in fig. 1 and fig. 2, the bluetooth speaker includes a first casing 1 and a second casing 7, a first soft layer 11 is disposed on one side of the first casing 1 opposite to the second casing 7, a second soft layer 8 is disposed on one side of the second casing opposite to the first casing, a through hole 2 is disposed between the first soft layer 11 and the second soft layer 8, an elastic member 6 is disposed in two adjacent through holes 2, one end of the elastic member 6 passes through the through hole 2 and is connected and fixed with the first casing 1, the other end of the elastic member 6 passes through the through hole 2 and is connected and fixed with the second casing 7, a clamping cavity is formed between the first casing 1 and the second casing 7, and more than one small air inlet and outlet holes 5 are disposed on the surfaces of the first casing 1 and the second casing 7 contacting with the elastic member 6.

In this embodiment, a speaker 3 is installed in a first housing 1, a bluetooth motherboard (not shown) is installed in a second housing 7, a bluetooth chip is installed on the bluetooth motherboard, the bluetooth chip is matched with a bluetooth audio frequency of a mobile phone, the bluetooth motherboard is connected with the speaker 3 through a connecting wire 4, the connecting wire 4 respectively passes through air inlet and outlet small holes 5 on the first housing 1 and the second housing 7, and an outer side end of the first housing 1 is opposite to the speaker and is provided with an audio outlet network 13.

In this embodiment, the elastic member 6 is a return spring, one end of the return spring is fixedly bonded to the end surface of the first housing through glue, the other end of the return spring is fixedly bonded to the end surface of the second housing 7 through glue, and the return spring can tension the first housing 1 and the second housing 7 by using the return spring when not being stretched, so that the first soft layer and the second soft layer are mutually contacted and compressed, and the first soft layer and the second soft layer are made to be a main structure without affecting the aesthetic property.

Wherein, the soft layer all adopts the elastic rubber layer that has the deformation resilience ability, and more than one air suction hole 14 has all been seted up to the relative elastic component one side in elastic rubber layer, and air suction hole 14 communicates with each other with the inside gas storage chamber 12 in elastic rubber layer, when not using, because contact each other between two soft layers, consequently has very good shock resistance, even drop subaerial, can not cause direct mechanical shock yet, reduces the impaired degree of inner assembly, increases the security.

Wherein, the anti-skid lines are carved on the opposite surfaces of the first soft layer 11 and the second soft layer 8. When needs clamping, as long as it is first to pull open, the second casing, make first soft layer and the direct separation contactless of second soft layer, this moment with between the mounting of its clamping outside, can utilize reset spring to compress tightly, accomplish the clamping, need not to set up the clamping subassembly in addition, after the clamping, the vibrational force that the speaker sound production produced can be transmitted for soft layer, the vibrational force can continuous vibration extrusion soft layer, make the inside gas in soft layer extruded, the gaseous part of extruding can pass and advance the aperture of giving vent to anger and enter into first, inside the second casing, dispel the heat respectively speaker and mainboard, increase certain heat dispersion.

The above description is only an embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that are not thought of through the inventive work should be included in the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope defined by the claims.
