Description

Technical Field

[0001] The utility model relates to the technical field of microphones and sound boxes, in particular to a handheld microphone sound box. Background Art

[0002] A handheld microphone speaker (or "speaker and microphone all-in-one" or other names) includes a speaker and a microphone. In the prior art, the sound head of a handheld microphone speaker is usually set vertically upward on the top of the speaker shell. This setting has at least the following characteristics: (1) In actual use, people are accustomed to making the microphone speaker and their mouths roughly at the same height (rather than pointing their mouths from top to bottom at the top of the microphone to make sounds), and there is a certain angle between the direction of sound wave propagation and the normal direction of the sound head (that is, there is a certain angle between the direction of the user's sound and the sound pickup direction of the sound head), which affects the sound pickup effect; (2) The angle between the normal line of the sound head and the normal line of the speaker is approximately 90°, and the sound emitted by the speaker itself will also be picked up by the sound head, affecting the sound pickup effect and even causing howling. In view of the above technical problems, the utility model proposes a new technical solution that can make the sound head of the handheld microphone speaker pick up sound more conveniently and cleanly during actual use. Utility Model Content

[0003] In view of the above-mentioned deficiencies in the prior art, the purpose of the present invention is to provide a handheld microphone speaker, aiming to solve the technical problems in the prior art that the sound head of the handheld microphone speaker is inconvenient to pick up sound and easily causes howling during use.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A handheld microphone speaker comprises a handle and a speaker housing. A speaker is arranged in the speaker housing. A sound head is obliquely arranged on the top of the speaker housing. The angle between the axis of the sound head and the axis of the speaker is greater than 90° and less than 270°.

[0006] Furthermore, in the handheld microphone speaker, the angle between the axis of the sound head and the axis of the speaker is an obtuse angle.

[0007] Furthermore, in the handheld microphone speaker, the sound head is arranged on a sound head bracket, and the sound head bracket is connected to the top of the speaker housing.

[0008] Furthermore, in the handheld microphone speaker, the top of the speaker shell is provided with an inclined surface, and a plug rod is provided on the inclined surface; the sound head bracket is provided with jacks equal in number to the plug rods and corresponding to each other, and each jack is respectively mounted on the corresponding plug rod.

[0009] Furthermore, in the handheld microphone speaker, the normal line of the inclined surface is parallel to the axis of the sound head.

[0010] Furthermore, in the handheld microphone speaker, a passive panel is also arranged inside the speaker housing.

[0011] Furthermore, in the handheld microphone speaker, the passive panel and the speaker are arranged back to back.

[0012] Beneficial effects: The utility model provides a handheld microphone speaker. Compared with the prior art, due to the inclined setting of the sound head, it has at least the following technical advantages: (1) when in use, the sound head is directed toward the user's mouth, which makes sound pickup more convenient; (2) the direction of the sound head is opposite to that of the speaker, and the sound emitted by the speaker will not be picked up by the sound head, making the sound pickup cleaner and preventing howling.

[0019] The utility model provides a handheld microphone speaker. To make the purpose, technical solution and effect of the utility model clearer and more specific, the utility model is further described in detail below. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not used to limit the utility model.

[0020] See also Figures 1 to 6 The utility model provides a handheld microphone speaker. The drawings are only used to explain the structural principle and are not proportional to the actual product. The drawings only show the structures related to the invention of this application, and some conventional structures are not specifically shown. For example, the drawings do not show conventional structures such as mesh heads and spray-proof cotton, so as to facilitate the observation of structures related to the invention.

[0021] The handheld microphone speaker comprises a handle 1 and a speaker housing 2, a speaker 31 is arranged in the speaker housing, a sound head 5 is arranged obliquely on the top of the speaker housing, and the angle between the axis 501 of the sound head and the axis 502 of the speaker is ( Figure 4 The angle A shown is greater than 90° and less than 270°. Figure 4 As shown, preferably, the angle between the axis of the sound head and the axis of the speaker is an obtuse angle.

[0022] In practical application, the sound head is arranged on the sound head bracket 4, and the sound head bracket is connected to the top of the sound box housing. By arranging the sound head bracket, the installation of the sound head is facilitated, and the sound head can also be reduced in vibration.

[0023] Preferably, the top of the speaker housing is provided with an inclined surface 21, on which an insertion rod 22 is provided; the sound head bracket is provided with jacks 400 equal in number to the insertion rods and corresponding to each other, and each jack is respectively sleeved on a corresponding insertion rod. During actual assembly, the sound head is set on the sound head bracket, and the jack of the sound head bracket is aligned with the insertion rod on the top of the speaker housing and buckled in.

[0024] Preferably, the normal line of the inclined plane is parallel to the axis of the sound head, that is, the angle of the inclined plane also determines the inclination angle of the sound head, and facilitates the connection between the sound head bracket and the sound box housing.

[0025] Furthermore, a passive panel 32 is also arranged in the speaker housing.

[0026] Preferably, the passive plate and the speaker are arranged opposite to each other, that is, the passive plate and the speaker are spaced 180° apart in the circumferential direction.

[0027] It is understandable that those skilled in the art can make equivalent substitutions or changes based on the technical solution and the utility model concept of the utility model, and all these changes or substitutions should fall within the protection scope of the utility model.
