Description

Crossover speaker

The present invention is a type of speaker, especially a speaker that integrates a high frequency, intermediate frequency and low frequency speaker unit.

In daily life, music can provide users with leisure and entertainment, and can also mediate physical and mental state. Therefore, if the user carries a mobile phone or an MP3 headset, or an audio device installed in the vehicle, or a home theater set in the home, This is to satisfy the user's desire to listen to music anytime and anywhere, but the above-mentioned device for outputting sound requires a plurality of speakers or speakers with multiple speakers to emit complete music, and the existing speaker is suitable for the user to pick the sound quality. Most of the ears are divided into three components: the tweeter (high frequency), the midrange speaker (intermediate frequency) and the woofer (low frequency), which are placed in the speaker to provide better sound effects for their audio characteristics. However, setting up three cells will increase the cost and space for the speaker to occupy a large space. Therefore, common solutions such as car audio combines a mid-range speaker with a woofer as a single unit, and then independently set the tweeter, or a multi-channel audio device such as a home theater, which integrates the treble and bass into the same speaker. , then set the woofer separately to another speaker to enhance its bass or bass Now, there are still concerns about poor sound quality and the need to not meet the sound quality, which is necessary for improvement.

As mentioned above, in order to improve the sound quality, the existing user speakers use three speaker units to generate high-pitched, mid-range and low-pitched sounds, which may increase the cost and space occupied by the speakers. Therefore, the main purpose of the present invention is to provide a point. The frequency speaker is mainly used to integrate high-pitched (high-frequency), mid-range (intermediate frequency) and low-frequency (low-frequency) speaker units on the basin frame, which can reduce the speaker volume and cost, and the loudspeakers can transmit through the loudspeakers. The body produces high-pitched, mid-range and bass, and the bass part is further adjusted by the diaphragm, the tuning piece and the air hole to adjust the bass sound, which solves the problem that the cost of using multiple speaker units increases and the space occupied by the speaker.

The main technical means adopted for achieving the foregoing purpose is that the crossover speaker comprises: a basin frame having a surface, a bottom surface, two sets of holes penetrating the surface, the bottom surface, a through hole and a plurality of air holes, The sleeve holes are located on opposite sides of the basin frame, the insertion holes are located in the center of the basin frame, and the air holes are arranged around the insertion holes; three speaker units are respectively arranged in the holes of the basin frame and two holes a set of holes; a diaphragm disposed on the surface of the basin, the edge of the diaphragm being connected to the basin frame; More than one tuning piece is disposed on the bottom surface of the basin frame and covers the air holes.

By using the crossover speaker composed of the foregoing components, the speaker units integrated on the basin frame can provide a single sound path, a second sound path and/or a three sound path signal by a crossover device to emit high, middle and low sounds. The diaphragm and the tuning film cover the surface and the bottom surface of the basin frame to form a gas chamber, and the speaker unit in the hole is energized to push the diaphragm to vibrate to generate sound, and the air in the air chamber can adjust the flow rate through the air holes. Or the vibration stroke of the diaphragm, which can improve the bass effect when the stroke is long, thereby integrating multiple speaker units into one, and the splitter can generate more than one sound path and reduce the volume and cost of the speaker. The bass portion of the speaker is further adjusted by the diaphragm, the tuning film and the air holes to solve the problem of the bass sound, thereby solving the problem that the cost of using the plurality of speaker units increases and the space occupied by the speaker.

Figure 3 is a top plan view of a preferred embodiment of the present invention.

Figure 4 is a cross-sectional view (I) of a preferred embodiment of the present invention.

Figure 5 is a cross-sectional view (2) of the preferred embodiment of the present invention.

With regard to the preferred embodiment of the present invention, please refer to Figures 1 and 2 As shown, it includes a basin frame 10, two first speaker units 20, a second speaker unit 30, a diaphragm 40 and two tuning sheets 50. As shown, the basin frame 10 has a surface and a bottom surface. The tray 10 is configured to provide the first horn unit 20 and the second horn unit 30, and the diaphragm 40 and the tunable sheet 50 are respectively disposed on the basin frame 10. Surface and bottom surface.

The basin frame 10 is formed with a recess 11 and two sleeve holes 12 formed on the surface of the basin frame 10. The sleeve holes 12 are through the surface and the bottom surface of the basin frame 10 and are located on the basin frame 10. The recesses 11 are disposed on opposite sides of the two sets of holes 12, and in the preferred embodiment, the sleeve holes 12 are circular, and the basin frame 10 is in the shape of a disk. The groove 11 has a larger width at both ends in the longitudinal direction thereof, and the width at the center is smaller and the edges at the center are curved to match the outer shape of the sleeve holes 12, and therefore, the insertion groove 11 The groove 11 is butterfly-shaped, but is not limited thereto. The recessed groove 11 is formed with a through hole 111 and a plurality of air holes 112. The insertion holes 111 are located at the center of the basin frame 10 and the recessed groove 11, and the air holes 112 are arranged around the insertion hole 111; as shown in the figure, The air holes 112 are arranged on the two sides of the insertion hole 111 in an arc-like manner in four and five numbers, and the number of the air holes 112 can be increased or decreased as desired by the user.
